293 The Strategic Road Network Episode
About this episode
Gary recounts his first EV road trip from Hampshire to Yorkshire, when motorway charging was sparse and often unreliable—then pivots to how the strategic road network (SRN) is rapidly improving. Using the M1 corridor as a proxy, he breaks down charger growth at motorway service areas, the rise of ultra-rapid hubs from operators like Gridserve, Apple Green, Tesla, Ionity, and others, and compares utilization and pricing. He argues MSAs are still busiest and may become strained as EV adoption grows, while off-motorway hubs are increasingly the smarter long-trip option.
This episode explores the current state and future of electric vehicle charging infrastructure along the UK strategic road network, focusing on the M1 corridor in particular.
Gary discusses charging patterns, infrastructure growth, and strategic considerations for EV drivers.
Key topics
- Growth of EV charging infrastructure on the M1 and strategic road network
- Charging patterns and peak times for EVs along the M1

Kia Soul
"The car I had at the time, a 30kWh Kia Soul, had a Chathamow connector, around 100 miles of range on the motorway and it charged at allegedly 80kW but in reality around 50kW"
The “30kWh” is how big the battery is. A bigger battery usually means you can drive farther before needing to charge, but real range depends on things like speed and weather.
This refers to a Kia Soul EV with a 30 kWh battery pack. Battery size strongly affects real-world range, especially on motorways where speeds and HVAC loads increase energy use.
Chathamow connector
"The car I had at the time, a 30kWh Kia Soul, had a Chathamow connector, around 100 miles of range on the motorway and it charged at allegedly 80kW but in reality around 50kW"
This is the plug type your EV uses to charge. If a charger has the wrong plug (or you don’t have the right adapter), you may not be able to use it easily.
A “connector” is the physical plug/interface used to charge the car. In the UK, early EV charging often involved different connector standards and adapter setups, which could affect convenience and compatibility at specific stations.
80kW
"and it charged at allegedly 80kW but in reality around 50kW if I was lucky."
80kW is how fast the charger is supposed to be. In real life, your car may charge slower than the sign says because of battery conditions and the car’s limits.
80 kW is the charger’s rated power, which largely determines how quickly an EV can add energy. However, real charging speed can be lower due to battery state of charge, temperature, charger limits, and the vehicle’s own maximum charging capability.
50kW
"and it charged at allegedly 80kW but in reality around 50kW if I was lucky."
50kW is the speed the charger really gave. That difference matters because slower charging means longer stops on road trips.
50 kW is the actual charging power the speaker experienced, lower than the advertised figure. This highlights how “nameplate” charger ratings don’t always translate to consistent real-world charging speeds.
range left to avoid running out
"Firstly, I was very cautious when I got my EV about making sure I stopped with plenty of range left to avoid running out and I think everybody's the same with their first EV."
They’re talking about keeping some extra battery so you don’t get stuck. If charging is slower than expected, having a buffer makes the trip less stressful.
This describes EV “buffering” on road trips: keeping extra battery reserve to reduce the risk of arriving at a charger with too little charge. It’s especially important when charging speed is inconsistent or chargers may be occupied or out of service.
MSAs
"And secondly, all of my stops were off motorway rather than at the MSAs. The reason I didn't use the MSAs is because at that time they were all equipped with a single, often temperamental ABT charger"
MSAs are the motorway rest stops. If they have good EV chargers, they make long drives easier; if not, you may need to plan stops elsewhere.
MSAs are motorway service areas—places designed for rest stops along highways. For EV drivers, the presence (or absence) of reliable chargers at MSAs can strongly affect trip planning and charging strategy.
Ecotristy network
"The reason I didn't use the MSAs is because at that time they were all equipped with a single, often temperamental ABT charger installed by Dale Vinson and his Ecotristy network."
This is the company/network that ran those chargers. If the network’s equipment was unreliable, it could make you choose different places to stop.
This refers to an EV charging network associated with the chargers at the time. Charging networks influence reliability, uptime, and where stations are placed, which can affect how comfortable drivers feel using them on trips.
ABT charger
"The reason I didn't use the MSAs is because at that time they were all equipped with a single, often temperamental ABT charger installed by Dale Vinson and his Ecotristy network."
This is a particular kind of charger. The host is saying it often worked poorly or unreliably, which is why they avoided using it.
An “ABT charger” is a specific charging hardware type referenced as being installed at motorway service areas. The speaker emphasizes that it was “often temperamental,” meaning it didn’t deliver consistent performance or availability.
Dodge Charger
"... equipped with a single, often temperamental ABT charger installed by Dale Vinson and his Ecotristy networ..."
The Dodge Charger is a car built for performance, with a focus on fast driving. If the podcast is talking about an “ABT charger,” it’s referring to the charging equipment used to power the car. The “temperamental” wording suggests the charging setup may not always work smoothly.
The Dodge Charger is a performance-focused sedan (or “muscle car” style vehicle) known for strong acceleration and a long-running lineup. In an EV-charging context, it may be discussed because owners sometimes use charging setups or adapters to power their vehicle, especially when charging infrastructure is inconsistent. That “ABT charger” mention suggests a specific charging hardware arrangement that can be a point of troubleshooting or reliability talk.
Nissan Leaf
"They were relatively low powered and often occupied with Nissan Leafs doing similar journeys,"
The Nissan Leaf is a common electric car. If lots of Leafs are charging at the same time, the chargers can be busy and you might wait or find them unavailable.
The Nissan Leaf is a widely sold EV, so it’s common to see them occupying popular charging stations. Mentioning Leafs in this context highlights how charger availability can be affected by demand during road trips.
Polar Plus
"The reason the Holiday Inn was a great place to stop was that they had 50 kilowatt chargers installed there by Polar Plus from Chargemaster who were later brought out by BP Pulse and with my subscription offering..."
Polar Plus is a company that helps put EV chargers in place. They’re involved in getting charging hardware installed at places like hotels.
Polar Plus is an EV charging operator/installer mentioned as having installed chargers at the Holiday Inn. In practice, companies like this handle the hardware deployment and sometimes ongoing site management for charging networks.
Chargemaster
"The reason the Holiday Inn was a great place to stop was that they had 50 kilowatt chargers installed there by Polar Plus from Chargemaster who were later brought out by BP Pulse..."
Chargemaster is a company that helped run EV charging. The host says it later got bought by BP Pulse, which can affect how you pay and which app you use.
Chargemaster is referenced as the original charger provider/brand that Polar Plus was associated with. The host notes it was later acquired by BP Pulse, which matters because it can change pricing, app support, and charger availability.
50 kilowatt chargers
"The reason the Holiday Inn was a great place to stop was that they had 50 kilowatt chargers installed there by Polar Plus from Chargemaster..."
“50 kilowatt” is how strong the charger is. A stronger charger usually means you can add energy faster, though your specific EV still has limits.
“50 kilowatt” refers to the charger’s power output, which strongly affects how quickly an EV can add energy. While real-world charging speed also depends on the car’s onboard charging limits and battery state of charge, higher kW generally means faster charging.
BP Pulse
"...installed there by Polar Plus from Chargemaster who were later brought out by BP Pulse and with my subscription offering..."
BP Pulse is an EV charging brand. The host says it ended up taking over Chargemaster, which can change how the chargers work for you day to day.
BP Pulse is mentioned as the company that later acquired Chargemaster. For drivers, ownership changes can influence charging network reliability, pricing models, and which payment/subscription options work at those stations.
EVED
"...if the government succeeds in implementing this ridiculous three-pence-a-mile EVED that they've announced, the EVED on that particular journey alone will cost me about £6 almost twice what the charging cost me in 2018."
EVED is referenced as a government policy described as “three-pence-a-mile” for EVs. The host uses it to compare future per-mile costs against earlier charging costs, highlighting how taxes/levies can change the economics of EV driving.
strategic road network
"...today's topic, which is just the strategic road network and the charging infrastructure around it. Stick around, this could be quite a long detailed episode. The EV Musings podcast is sponsored by Zatmap..."
The strategic road network is the UK’s main set of big roads—motorways and major A-roads. The host uses it to talk about where EV charging is most important and how it’s organized.
The strategic road network (SRN) is a UK-managed set of major motorways and key A-roads. In this segment, the host explains it as roughly 4,500 miles in England managed by the highways agency, and uses it as the framework for discussing how charging infrastructure is planned and deployed along high-traffic routes.
charging infrastructure
"...today's topic, which is just the strategic road network and the charging infrastructure around it. Stick around, this could be quite a long detailed episode..."
Charging infrastructure just means the network of EV charging stations. Where they’re placed (especially on big roads) can make EV road trips easier or harder.
Charging infrastructure refers to the physical network of EV chargers—where they are located, how many there are, and what power levels they provide. The host ties this to the SRN, implying that charger placement along major roads affects long-distance EV usability.
Zatmap
"The EV Musings podcast is sponsored by Zatmap, the go-to app for EV drivers, helping you find and pay for public charging with confidence."
Zatmap is the episode sponsor and is described as an app for EV drivers to find and pay for public charging. Apps like this typically aggregate charger locations, show availability/pricing, and streamline payment so drivers can charge with fewer surprises.
M1 Corridor
"In particular, I want to look at how it's changing for one specific road I use quite a lot, which is the aforementioned M1 Corridor. The M1 is considered one of the most heavily trafficked roads in the network..."
The M1 Corridor is just a specific stretch of the UK’s main M1 motorway. The episode uses it like a “test route” to show how EV charging has improved (or not) where people actually drive every day.
The M1 Corridor refers to the UK’s M1 motorway route and the surrounding travel corridor. In this segment, the hosts use it as a real-world case study for how EV charging availability and reliability have changed over time along a heavily used road.
motorway service areas
"...things have improved on all the motorway service areas in the UK and having said that, only about three or four years back, the M1 Corridor was still a relative wasteland of chargers..."
Motorway service areas are the official rest stops along the UK’s motorways. They’re important for EVs because that’s where you can reliably find chargers during long trips.
Motorway service areas (MSAs) are the UK’s designated rest stops along motorways, typically containing fuel stations and EV chargers. The segment focuses on how MSA charging went from sparse/less reliable to more robust coverage over time.
charger reliability and availability
"...the M1 Corridor was still a relative wasteland of chargers... every motorway service station on the M1 had at least one charger. It was usually a grid serve... In some cases... the chargers that were there were completely shut down and covered up."
It’s not enough for chargers to be “somewhere”—they also have to be working when you arrive. The host is describing a time when chargers on the M1 were sparse and sometimes even shut down, which makes planning a trip much harder.
The segment repeatedly contrasts “chargers exist” with “chargers are usable,” citing cases where chargers were shut down and covered up and describing how options were scarce near exits. For EV road trips, reliability and availability (not just raw charger count) determine whether a route is realistically drivable.
medium power
"It was usually a grid serve and it was classed as medium power, which meant it was under around 100 kilowatts, more often than not it was 50 kilowatts."
“Medium power” means the charger is fast, but not the fastest available. In this episode they’re talking about chargers around 50 to 100 kilowatts, which means you’ll generally spend more time charging than at the newest ultra-fast stations.
“Medium power” in EV charging usually refers to DC fast-charging levels that are slower than the latest high-power systems. In this segment, the host ties it to roughly 50–100 kW, which affects how quickly different EVs can replenish charge during a stop.
grid serve
"It was usually a grid serve and it was classed as medium power, which meant it was under around 100 kilowatts..."
Gridserve is a company that runs EV charging sites. The host is using it to describe what kind of chargers were common on the M1 back then, and how that has changed.
Gridserve is referenced as the typical operator for the chargers the host saw on the M1 during the earlier period. In the context of EV travel, operator choice can affect maintenance practices, uptime, and how quickly sites get upgraded.
kilowatts
"...it was classed as medium power, which meant it was under around 100 kilowatts, more often than not it was 50 kilowatts."
Kilowatts (kW) are a way to describe how fast a charger can deliver power. Higher kW usually means you can add charge faster, though your specific car still matters.
Kilowatts (kW) measure charging power—how quickly energy can be delivered to the battery. Higher kW generally means faster charging, but the actual rate also depends on the EV’s charging curve and the charger’s limits.
Markham Vale
"There were very few options, you had a couple of locations such as Markham Vale near Chesterfield... Again, Markham Vale in South Yorkshire comes to mind..."
Markham Vale is a real place the host points to where you could find chargers off the main motorway stops. They’re basically saying that, back then, only a few locations like this made the route workable.
Markham Vale is mentioned as a specific charging location near Chesterfield, later reiterated as being in South Yorkshire. The host uses it as an example of the limited “outside the motorway service areas” options that existed when the M1 corridor still lacked dense coverage.
IONC
"...now sadly no longer there, although there are a handful of IONC units still remaining there."
IONC is an EV charging operator/brand referenced here as still having a handful of units remaining at the Milton Keynes Coatway area. This matters because the host is contrasting past coverage with what’s left now—showing how networks can thin out over time.
Instavolt
"There might have been a couple of Instavolt chargers at McDonalds or KFC locations just off the junctions..."
Instavolt is a company that provides EV chargers. Here it’s mentioned as one of the few charger options you might find near places like fast-food restaurants off the motorway exits.
Instavolt is an EV charging operator/brand. The segment uses it as an example of “outside the motorway service areas” charging options—typically smaller, site-specific installations at retail locations.
Osprey charging install
"...or even an Osprey charging install attached to a Marston's pub in a similar place."
Osprey is a company that runs EV charging. The host is saying that, off the motorway, chargers were rare and often depended on specific places like pubs or restaurants.
Osprey is an EV charging operator/brand, and the phrase “Osprey charging install” refers to a charger setup placed at a specific venue. The host’s point is that outside MSAs, charger coverage was extremely limited and often tied to particular businesses.
ultra rapid chargers
"there have been 174 additional ultra rapid chargers added at the MSAs along the M1 in the last 24 months alone... a site in this case is a block of ultra high powered chargers belonging to one CPO"
Ultra rapid chargers are the fast EV chargers you want for road trips. They can refill your battery much quicker than standard chargers, and the host is saying there are many more of them now along the M1.
“Ultra rapid” chargers are high-power EV charging stations designed to add significant energy quickly compared with slower public chargers. In this segment, the host tracks how many ultra rapid chargers have been added at motorway service areas (MSAs) along the M1, and how that capacity is organized by sites and operators.
CPO
"a site in this case is a block of ultra high powered chargers belonging to one CPO at either a northbound or a southbound MSA... some sites have multiple CPOs at each location"
A CPO is the company that runs the charging equipment at a station. The host is saying some motorway stops have chargers from one operator, while other stops have chargers from more than one operator.
CPO stands for Charge Point Operator, the company responsible for operating a set of charging points at a location. The host uses CPOs to define “sites” at MSAs—charging blocks belonging to one operator—and notes that some locations have multiple CPOs.
tip shelf or trowel northbound services
"Now at the moment these include tip shelf or trowel northbound services, does that make"
This is a specific service stop on the motorway. The host is probably pointing out whether it has fast chargers or only slower ones.
This appears to be a reference to specific motorway service locations on the M1 (northbound). The host is likely about to discuss which of these sites only have older, medium-power chargers, which matters for trip planning.
Ionity
"Leeds Skelton Lakes is an existing MSA that has no grid serve chargers in there at all, just ionity of which there are six 350kW units."
Ionity is a company that installs and runs fast EV chargers. Here, it’s mentioned because that particular motorway stop has Ionity’s very high-power chargers.
Ionity is a high-power EV charging network operator. In this segment, it’s mentioned as the operator at Leeds Skelton Lakes, where there are six 350kW units, illustrating how different networks populate different motorway service areas.
MSA (motorway service area)
"Leeds Skelton Lakes is an existing MSA that has no grid serve chargers in there at all... There's even a brand new welcome break services at Junction 33 Rotherham..."
An MSA is a motorway rest stop where you can park, eat, and (in this case) charge an EV. They’re using MSAs to talk about where fast chargers are located and which companies provide them.
MSA stands for motorway service area—dedicated rest stops on major roads that often host EV charging. The episode uses MSAs to compare how charging infrastructure is distributed across the UK motorway network, including which operators are present and at what power levels.
Welcome Break
"before we go much further, let's talk about grid serve and welcome break... This is a welcome break site which for whatever reason shut down the grid serve chargers there."
Welcome Break runs the motorway rest stops. They’re talking about how some Welcome Break locations had certain fast chargers turned off, and how other fast-charging brands were added later.
Welcome Break is a UK motorway service area operator. The episode discusses how Welcome Break sites can have grid-connected chargers shut down or absent, and then later redeploy different charging equipment (including high-power chargers from other operators).
Moto Charge
"Moto, who are one of the bigger MSAs, have recently added six of their own Moto Charge units in at Toddington services with this new Moto Charge brand."
Moto Charge is a charging service brand used at motorway stops. The episode is comparing how Moto is adding its own chargers alongside other companies’ chargers at the same service area.
Moto Charge is a charging brand associated with Moto, which operates motorway service areas (MSAs). In this segment, the hosts discuss Moto adding its own chargers at Toddington services and positioning them near existing grid operators’ chargers.
360kW
"They're almost co-located with the 12 grid serve chargers which is an increase from six to two years ago and are faster at 400kW versus 360kW than the grid serve ones."
360 kW is another measure of charger speed. It’s still very fast, but the episode is comparing it to an even faster 400 kW option.
360 kW is also a high-power DC fast-charging level, but it’s lower than the 400 kW being discussed for Moto Charge. The hosts frame it as a practical difference in charging speed at the same MSA locations.
400kW
"They're almost co-located with the 12 grid serve chargers which is an increase from six to two years ago and are faster at 400kW versus 360kW than the grid serve ones."
400 kW refers to very high-power DC fast charging, which can significantly reduce charging time compared with lower-power stations. The segment uses it to compare charger performance at the same location (Moto Charge vs Gridserve).
kWh
"Grid server priced at 85pkWh at Toddington and Moto charger priced at 89pkWh is the extra 4pkWh worth it for the additional potential 40kW of charge speed?"
kWh is how much electrical energy you’re buying when you charge. The episode compares the price per unit of energy and asks whether paying more for faster charging is actually worth it for most drivers.
kWh (kilowatt-hours) is the unit used for electricity consumption/energy pricing in EV charging discussions. Here, the hosts compare per-kWh prices (e.g., 85p/kWh vs 89p/kWh) and debate whether the extra cost is worth the speed gain.
Tesla Superchargers
"Well as I mentioned earlier the Zionity at Leeds skeleton lake and Tesla superchargers not open to the public at Woodall, Newport Pagonal North and Southbound and Rotherham services."
Tesla Superchargers are Tesla’s fast chargers. The hosts say that at some locations they aren’t available to everyone, which affects who can use them.
Tesla Superchargers are Tesla’s fast-charging network, referenced here as not open to the public at certain motorway service locations. This highlights access differences between networks (public vs restricted access) even when chargers are physically present.
Applegreen
"Applegreen have installed units at the following sites, Leicester Forest East North and Southbound with 16 units each, Rotherham services 20 units, Woodall 6 units Northbound and 16 Southbound, Newport Pagonal North and Southbound 16 units each side, London Gateway Junction 24 units."
Applegreen runs motorway service stations, and they’ve been adding EV chargers at several stops. The hosts are listing how many chargers they put at each location.
Applegreen is a motorway services operator that the hosts say has installed charging units at multiple MSA sites along the M1. The segment provides a site-by-site breakdown of charger counts, emphasizing how charger capacity is being distributed across locations.
plug and charge
"Although as they're all ABB units which don't support plug and charge and have an appalling user interface I would probably contest that but maybe that's just my personal point of view."
Plug and charge means you plug the car in and it starts charging automatically, without you tapping an app or card first. The episode says these chargers require extra interaction, which makes them less convenient.
Plug and charge is a feature where an EV can authenticate and start charging automatically when plugged in, typically using certificates and secure communication. The hosts criticize that the ABB chargers mentioned don’t support plug and charge, which can mean more steps (apps/cards) to begin charging.
ABB
"Although as they're all ABB units which don't support plug and charge and have an appalling user interface I would probably contest that but maybe that's just my personal point of view."
ABB is a company that makes some of the charging equipment. The hosts are saying that the ABB chargers at these locations aren’t as user-friendly because they don’t do plug-and-charge and the screens/apps are awkward.
ABB is an industrial technology company that also supplies EV charging hardware. In this segment, ABB chargers are singled out for not supporting plug and charge and for having a poor user interface, affecting user experience at the sites discussed.
BMW M6
"...nd Beckinsfield on the M40. Instavolt are at the M6 services at Corley and then Apple Green Electric ..."
The BMW M6 is a sporty, high-performance car made by BMW. The podcast mentions motorway services and charging stops, which is relevant if you’re planning a trip and need places to charge along the route. It’s basically about where you can stop and plug in during travel.
The BMW M6 is a high-performance version of BMW’s 6 Series, built for strong power and sporty driving dynamics. It may come up in a charging-route discussion because the podcast is referencing specific charging stops along a motorway corridor, which matters for planning trips. The mention of “M6 services” and nearby charging locations suggests the car is being considered in real-world travel scenarios where charging access and timing are important.
utilization figures
"With figures like this you'd think that Apple Green would be way ahead of GridServe in terms of sessions and usage right? Well looking at the utilization figures though a different picture emerges."
Utilization figures are a way to measure how busy the chargers are. Instead of just counting chargers, it looks at how many times each charger gets used.
Utilization figures describe how intensively chargers are used—often measured as sessions per charger per month. The segment argues that utilization can reveal which network is actually meeting demand, even if another operator has more total chargers.
sessions used
"The 108 ultra rapid chargers operated by GridServe were used nearly 27,000 times each month in December 25 and January 26. Compare that with the higher number of chargers for Apple Green that were only used a little over 16,000 times per month across the same two months."
Sessions used means each time someone plugs in and charges. The podcast uses session counts to compare how often different charging companies’ stations are being used.
“Sessions used” refers to individual charging events recorded per charger over a time period. In this episode, sessions used are used to compare utilization between networks and to infer demand patterns along the same route.
economic theory
"Now it's not cost because Apple Green charge 83 kWh and GridServe charge usually 89 kWh although some sites do vary slightly. In the perfect world of economic theory nobody would use the GridServe chargers unless all the Apple Green units were being used as a perfect market would go for the cheapest charger every"
They’re talking about a basic idea from economics: in a perfect world, people would always pick the cheapest option. The podcast suggests real charging choices don’t follow that perfectly.
The hosts invoke “economic theory” to describe a simplified market where EV drivers always choose the cheapest option. They use this as a contrast to the real-world utilization results, implying that factors beyond price (location, reliability, queueing, access rules) influence charging behavior.
first mover advantage
"But what he does highlight is the GridServe first mover advantage when it comes to motorway service charging... customer recognition and familiarity alongside a well-known brand."
First mover advantage means the company that gets there early can build trust and recognition before others arrive. The episode says GridServe benefited from being early, but competitors are now catching up.
“First mover advantage” refers to the benefits a company gains by being early in a market—such as brand recognition, customer familiarity, and early site partnerships. The host argues GridServe’s early presence at motorway charging locations is now being challenged as other operators expand.
motorway service charging competition
"Now this is of course good news for drivers... you can have your choice of charge point operators with different pricing strategies..."
This is basically about EV charging becoming a “choice” at motorway stops. Instead of one company dominating, multiple charging networks show up and drivers can pick the one that’s cheaper or more convenient.
The segment is about how EV charging at UK motorway service areas is becoming more competitive. As more operators deploy chargers at the same sites, drivers can choose between networks with different pricing strategies and access rules (Tesla-only vs open-to-all).
charging access rules (Tesla-only vs open to the public)
"Now this is a little bit remarkable given that Tesla have as a rule kept their motorway service area charges for Tesla drivers only... There are exceptions of course and this is one of them."
The host contrasts Tesla’s usual approach—keeping many motorway chargers restricted to Tesla vehicles—with exceptions where Tesla Superchargers are open to non-Tesla EVs. This affects real-world usability and can change which network is “best” for a given driver.
EVOLT network
"Or there's Gloucester services that have the EVOLT network with their 150 kWh charges at 69 pence a kWh and the Tesla public superchargers at 57 pence a kWh..."
EVOLT is a charging brand/operator mentioned at a specific motorway stop. The episode uses it to compare charging costs between different companies.
EVOLT is referenced as a charging network operating at Gloucester services, with the host quoting its per-kWh pricing and comparing it to Tesla public Superchargers nearby. This matters because it illustrates how pricing can vary widely even within the same service-area region.
M1 motorway service sites
"Consider also also that on the M1 there are only 13 official motorway service sites. Here they are, let me see if I can get through them all."
They’re talking about how many charging/rest stops exist along the M1 motorway. Because there are only a limited number, they can get crowded as more EVs use them.
The episode segment lists the limited number of official motorway service sites along the M1 and notes that one has recently opened. This framing sets up the later argument about how constrained charging infrastructure can be when EV adoption grows.
charger utilization / sessions per day
"The data I have from Zatmap indicate that each GridServe unit along the M1 corridor is being used an average of eight sessions per day."
Utilization is basically how busy a charging station is. If it’s used a lot every day, it’s more likely that the chargers will already be taken when you get there.
“Utilization” describes how heavily a charging site is used over time, often measured as sessions per day. Higher utilization means chargers are more likely to be occupied when you arrive, which increases the chance of waiting or having to reroute to another site.
charging demand peaks and troughs (time-of-day load)
"but this increase won't be evenly distributed across the day they're going to be charging speeds where more vehicles stop so around mealtimes are typical examples and there are going to be troughs where there is very little call for charging"
Charging demand changes depending on the time of day. More people stop to charge at certain times (like around meals), and fewer people charge late at night, so some periods will be much busier than others.
The episode explains that EV charging demand won’t increase evenly across the day; it will cluster around typical stop times (like mealtimes) and drop during low-traffic hours. This creates “peaks” where chargers are most likely to be occupied and “troughs” where capacity is underused.
probability of arriving to an occupied charger
"Now what this means is that there's a very high probability that the charges at your favorite msa's are going to be in use when you arrive there"
The big takeaway is that if charging stations get busier, you’re more likely to arrive and find the chargers already taken. That can mean waiting or having to choose a different stop.
The hosts connect utilization and time-of-day demand to a practical outcome: the likelihood that chargers at your preferred MSAs will already be in use when you arrive. This is essentially a queueing/availability problem—more EVs and more peak-time clustering increase the chance you’ll need to wait or reroute.
charging hubs (six or more rapid or ultra rapid devices)
"the number of hubs six or more rapid or ultra rapid devices has increased by just over 39 percent last year to 748"
A charging hub is a place where several fast chargers are grouped together. That makes it less risky to stop there because you’re more likely to find an available charger.
A “hub” in this context means a location with multiple rapid/ultra-rapid chargers clustered together, reducing the chance you’ll arrive and find no available stalls. The episode highlights growth in the number of these multi-charger hubs, which improves reliability for long-distance EV travel.
Pogo
"if i look at non tesla super chargers that have six or more devices there's pogo who have sites at the holiday in wakefield nice chargers not a great location to be honest"
Pogo is a company that provides public EV charging. The hosts are pointing out where Pogo has clustered fast chargers, and they even note when a location isn’t ideal.
Pogo is a charging network operator referenced here as providing multi-charger sites (six or more devices) near the SRN. The episode also comments on site quality/location, which matters because charger access and convenience affect real-world usability.
Sainsbury Smart Charge
"junction 35 sainsbury smart charge has one at fossilway near lester which is junction 21"
Sainsbury Smart Charge is a charging setup associated with Sainsbury’s. The idea is that some charging stations are placed near stores, so you can charge while you’re already stopping for something.
Sainsbury Smart Charge is referenced as having a charging site near a major junction, illustrating how retailers are also deploying EV charging. Retail-adjacent charging can be convenient because it pairs charging with shopping or errands during longer stops.
rapid charging
"raw charging coming on this podcast this season they have two hubs on the root but neither of them is a quick diversion from m1 shall recharge"
Rapid charging means the charger is faster, so you add more charge in less time. That matters on road trips because you don’t want to spend too long stopped.
“Rapid charging” refers to higher-power charging intended to add meaningful energy in a short time compared with slower chargers. In route planning, the presence (or absence) of rapid chargers often determines whether you can top up quickly enough to keep to schedule.
detour
"there's one just off a road just off a road just off the m25 near the m1 junction it's about a five minute diversion and 2.6 kilometers or 1.5 miles"
A “detour” here refers to leaving the main motorway corridor to reach a charging location, then rejoining the route. For EV planning, detours directly affect total trip time and whether the stop is worth it.
hub rather than a small site
"for a long distance drive i'm heading for a hub rather than a small site where a charger might be occupied or even worse iced"
A “hub” usually has several chargers in one place, not just one. That makes it less likely you’ll show up and find every charger in use.
In EV charging terms, a “hub” typically means a location with multiple chargers (often higher throughput and redundancy) compared with a single or small site. This reduces the risk of arriving to an occupied charger and improves trip reliability.
iced
"where a charger might be occupied or even worse iced what does this mean for me as an evie driver"
“Iced” means the charger is taken up by a regular car, so an EV can’t plug in. It’s frustrating because you can arrive ready to charge and still be stuck.
“Iced” is EV slang meaning a charger is blocked by a non-EV vehicle (often an internal-combustion car) so the EV can’t use it. It’s a practical reliability problem for drivers planning charging stops.
charging provision is increasing rapidly
"now firstly the charging provision is increasing rapidly we know this because zapmatt published the figures for charger growth on a regular basis"
They’re saying EV charging is getting added faster than before. That means a route that’s inconvenient today may be much easier later.
This segment highlights the trend that EV charging infrastructure is expanding quickly. The key takeaway is that the network is improving over time, so route viability can change even within a short period.
zapmatt
"we know this because zapmatt published the figures for charger growth on a regular basis"
Zapmap is a service that helps you find EV chargers. They also track how many chargers are being added, which is why the hosts cite their numbers.
Zapmap is a UK EV charging platform that tracks charger locations and availability, and it publishes data on charging growth. Mentioning Zapmap here signals the episode’s charging-infrastructure claims are based on tracked, regularly updated figures.
multi-unit dependable charging hubs
"i'm quite content to know that when i go and see my parents i have a bigger choice now than i did eight years ago of large multi-unit dependable charging hubs at which i can choose to charge"
This describes a charging site with several chargers that are more likely to be working when you arrive. More chargers at one place usually means you’re less likely to be stuck waiting.
“Multi-unit” means multiple charging stalls at the same site, and “dependable” implies reliability and availability rather than just theoretical capacity. The point is that having several working chargers reduces the risk of downtime and makes charging more predictable.
zapmap
"and i'm looking at you fast nerd the ev musings podcast is sponsored by zapmap to go to app for ev drivers helping you find and pay for public charging with confidence see what charge points are available right now with live availability"
Zapmap is an app for EV drivers. It helps you find charging stations nearby and see which ones are available right now, and it can help you pay.
Zapmap is a UK EV charging app and platform that helps drivers find public charge points and check live availability. The sponsor message emphasizes using it to pay and navigate charging with confidence.
fast nerd
"and i'm looking at you fast nerd the ev musings podcast is sponsored by zapmap"
This sounds like a specific person or account being mentioned by name. It’s probably a playful callout rather than a technical EV charging concept.
“Fast nerd” appears to be a person or channel being called out in a playful way, likely related to EV charging coverage or commentary. It’s not a standard automotive term, but it’s a named reference worth clarifying for listeners.
