About this episode

Episode 300’s season-ending round table digs into why EV charging road signage is inconsistent and what drivers need to see—like kWh, speed, and price—especially on the SRN where approvals are strict. Guests discuss co-located CPOs, how signage affects confidence and utilization, and the economics behind reliability, maintenance, and pricing. The conversation then broadens to measurement accuracy (kilowatts per pound), ad-supported charging screens, and how incentives could offset friction. It closes with sponsor reads for ZapMap.

Dodge Charger

The Dodge Charger is a car that’s built for performance, meaning it’s designed to feel quick and powerful when you drive. It’s a sedan, so it has four doors and a trunk, and it’s been popular with drivers who want a sporty feel. In podcasts, it may be mentioned when people talk about how performance cars are changing with new technology.

kilowatt hour

"as you're entering the charge site, [259.3s] there's a tow term or something nearby that will state the kilowatt hour that's available, [264.3s] the speed of the charging, the price per kilowatt hour."

A kilowatt hour (kWh) is a way to measure how much electricity you’re getting. EV chargers often show kWh-related info so you can understand what you’ll be paying for and how much energy you’re taking in.

tariffs

"And I don't know how easy it is to change [270.4s] that based on the different tariffs, the rate, the time of day that you're charging, because of [274.1s] course those energy prices will change."

Tariffs are the charging price rules. They can change depending on things like the time of day, so the same charger might cost more or less at different times.

charging infrastructure

"which is for another [327.2s] provider. And it just builds this big visual impact that the charging infrastructure is here, [332.6s] where they may not necessarily see it."

Charging infrastructure refers to the network of EV charging points and how they’re presented and managed for drivers. The discussion here is about how visible signage and information can make that infrastructure feel “real” and usable, even if drivers don’t notice chargers without prompts.

traffic signs regulations and general directions rules

"because they do broadly adopt that kind of wider, it's called the [367.5s] something very long, the traffic signs regulations and general directions rules, which are what [372.2s] applies to the major roads."

These are the UK rules that control how road signs should look and where they should go. If local councils follow the same rules, EV charging signs are more consistent and easier for drivers to understand.

EV hub sign

"And that is that requires as a CPO us to apply for it, [615.5s] we would pay for it all ourselves. And because it's on the SRN, which is national highways [619.5s] managed as opposed to the local authority road, it's where it's a little bit more freefall,"

It’s a special road sign that tells drivers where EV charging is. The episode explains that getting these signs approved and installed involves rules and paperwork, especially on major roads.

CPO

"And that is that requires as a CPO us to apply for it, [615.5s] we would pay for it all ourselves. And because it's on the SRN, which is national highways [619.5s] managed as opposed to the local authority road,"

A CPO is the organization that runs EV charging points. They’re the ones who handle the charging site and, in this case, the process and cost for getting certain EV signs approved.

SRN

"And because it's on the SRN, which is national highways [619.5s] managed as opposed to the local authority road, it's where it's a little bit more freefall, [623.3s] depending on what they want to permit."

SRN means the UK’s main road network—motorways and big A roads. The hosts say rules for signs are tougher there because they’re focused on safety.

national highways

"And because it's on the SRN, which is national highways [619.5s] managed as opposed to the local authority road,"

National Highways is the organization responsible for the UK’s major roads. In the episode, they’re mentioned to explain why the rules for signs are stricter on those roads.

topography

"And it is quite a process. It's things like all sorts of surveys, topography, [637.6s] like will you add extra weight to the existing signs, such as the topples over,"

Topography is the study of land shape and elevation, and it matters for road signage because it affects visibility and placement. The hosts mention it as part of the process for approving and installing EV signage.

surveys

"And it is quite a process. It's things like all sorts of surveys, topography, [637.6s] like will you add extra weight to the existing signs, such as the topples over,"

Surveys are checks done on-site to understand what’s there and what changes are safe and allowed. Here, they’re part of the paperwork and planning for EV signs.

purpose built hub

"when you just want to say [645.9s] there's an amazing hub of 16 charges at the next services or not even at the services, [650.6s] you know, there's a purpose built hub that we've spent, you know, upwards of a million pounds"

A purpose-built hub is a charging area that was designed specifically for EVs. The episode is saying these can be expensive and take a lot of effort to create.

Concept

co-location

"whilst it seems like fierce competition, I think in time, having co-location is not the worst thing in the world because it increases the availability, so it increases the, I guess, the reassurance for drivers that there will be a charger there."

“Co-location” here means multiple charging companies put their chargers at the same location. That can help because if one charger is busy or broken, there are other options nearby.

rapid charge points

"okay, in total, there are 40, 50 rapid charge points there for this merits, a non-branded EV hub sign on the main A road and that's really powerful..."

“Rapid charge points” are faster public EV chargers. They’re meant to get you charging quickly so you can add range in less time than slower home-style chargers.

EBCI

"the reliability of the charge, the safety and accessibility that user experience, and now recently with my EBCI hat on,"

EBCI is an acronym mentioned by the speaker, but they don’t explain it in this clip. It likely refers to a specific group or role connected to EV charging, but we’d need the full episode or surrounding context to be sure.

power delivery

"I think coming to that point about the overall [1227.2s] underperformance of then the power delivery is really, is kind of that next step. And I'd love [1232.2s] to hear a bit more, because I think it would be useful to talk about the analogy with petrol"

Power delivery refers to how much electrical power a charger actually provides to the vehicle over time. The discussion frames “underperformance of the power delivery” as the next step beyond site design and safety—meaning the charger must deliver the promised charging rate reliably.

wet fuel markets

"Absolutely. So in, we would call it the wet fuel markets. [1251.3s] So in the wet fuel market, they have, they are subject to inspections,"

“Wet fuel markets” means normal petrol/diesel fuel stations. They’re using that as an example of how those stations are regulated for accurate measurements, and how EV charging should be held to a similar standard.

metrology inspections

"So in, we would call it the wet fuel markets. [1251.3s] So in the wet fuel market, they have, they are subject to inspections, [1256.5s] metrology inspections, to ensure that the accuracy of the fuel per litre is, you know, [1262.4s] on the nose."

“Metrology inspections” means official testing to make sure measurements are accurate. In EV charging, it’s about confirming the charger is delivering the right amount of energy so you’re not overcharged.

margin for error

"So in the wet fuel market, they have, they are subject to inspections, metrology inspections, to ensure that the accuracy of the fuel per litre is, you know, [1262.4s] on the nose. I think there's like a 0.5% margin for error within that."

A “margin for error” is the small amount of inaccuracy that’s still considered acceptable. The point is that the system shouldn’t be meaningfully off when it measures what you’re paying for.

four port

"I think there's like a 0.5% margin for error within that. And if a single pump on a [1269.0s] four port fails that accuracy test, they'll shut the whole thing down until it's been recalibrated."

“Four port” means the charger has four separate charging connectors. The example is that if one connector’s measurements are wrong, the whole station might be taken offline until it’s fixed.

kilowatts per pound

"So how do we ensure that the margin for error and [1301.7s] delivering kilowatts per pound is accurate and that people aren't paying more for less?"

“Kilowatts per pound” is a way of saying “how much charging you get for the price.” The concern is that if measurements are off, you could pay more but get less charging than you should.

canopies

"particularly hubs is canopies. Now, if we look at, if we split the charge point operators who are out there sort of down the middle, there are a number who will always put canopies in at every site, MFG, Fastnet or example."

A canopy is a roof built over an EV charging station. It keeps the charger and people more comfortable in bad weather, but it can cost a lot to install.

Term

planning permission

"Fastnet are very selective and they will only build where they can get the permission for a canopy. So one of the barriers, as I know you know, is that there's things like planning permission and other kind of reasons and restrictions why canopies might not work."

Planning permission is official approval from the local council for building something. A charging-station canopy may need it before construction can happen.

case by case basis

"This moment in time, it is a case by case basis. I was always subject to those other things. It's a retail, you know, we operate quite a lot in retail car parks."

“Case by case” means they decide based on the specific location. Some sites can justify a canopy, while others can’t because of cost or approvals.

range anxiety

"She said, well, it was obviously range anxiety. And I said, and how did you solve that?"

Range anxiety is the worry that your EV battery won’t last long enough to get to a charger. It’s especially common when you’re new to EVs and aren’t sure how far you can really go.

public charging

"I said, and had you ever driven long distance and charged in public? She said, no. I said, how was it?"

Public charging is charging your EV at chargers you don’t own—like chargers in towns or at public locations. It matters because it’s different from plugging in at home.

third party advertising on charges

"But one thing we're starting to see now is the use of third party advertising on charges. Some of the more recent designs allow, for example, videos to be displayed as you're charging."

This is when EV chargers show ads on their screens while you’re charging. The hope is that those ads help pay for the charging, so the electricity cost could be cheaper.

three-pin charging cable

"Yeah, and I'm kind of okay with that. But if it said, for example, do you need a new three-pin charging cable, go to evcables.co.uk for a wide range of options, that's a different kind of advertising."

It’s the common type of EV charging lead that plugs into a regular wall outlet using a standard three-prong plug. It’s usually for slower charging compared with dedicated public chargers.

QR code

"And, you know, if there's a QR code saying, scan here and get a discount on your evcables, I think that's, from my point of view, acceptable."

A QR code is a little square you scan with your phone camera. Here, it’s used to quickly take you to a website or deal related to charging.

Concept

pricing hurdle

"I do take your point there about if you've got to, if there's, I did an episode of weeks ago where I talked about the pricing hurdle, which is a hurdle that you have to cross or go over to be able to get a discount."

A “pricing hurdle” is the minimum price/cost barrier you need to get over before a discount really matters. In this case, it’s like: you have to do something (like watch an ad) before the cheaper charging price kicks in.

landing page

"So you're right in that if you were going to go and buy, you know, some cabling and you wanted to scan a QR code, it should take you to a separate landing page for that"

A landing page is the specific webpage you end up on after you click a link or scan a QR code. It’s usually set up so the page matches the offer you were promised.
