About this episode

Average used EV battery health in a large UK study lands at 95.15%, with an annual degradation rate of 2.3% and a median of 93.5% for 4–5 year cars—pushing back on worst-case “scare stories.” The hosts then track UK BEV growth past 2 million and unpack drivers like ZEV mandate pressure and changing economics. They pivot to the electric Hilux: 150 miles WLTP, ~110–120 real-world, plus towing/payload limits. Charging coverage, road charges, and retail “dwell time” charging round it out.

UK battery health study (8,000 EVs)

"This week, 8,000 electric cars tested. The UK's largest battery health study just dropped. The answer is not what the scare stories tell you. We'll go through the real numbers."

The hosts talk about a big UK study that tested thousands of EV batteries. They use it to answer whether buying a used EV battery is really risky.

Company

Electroverse

"And I know that there was a study by Electroverse and Auto Trader Insight this week. And one of the great worries and concerns is about battery health in used electric cars."

Electroverse is mentioned as a company that helps measure how healthy EV batteries are. The episode uses their study results to challenge common fears.

Company

Auto Trader Insight

"And I know that there was a study by Electroverse and Auto Trader Insight this week. And one of the great worries and concerns is about battery health in used electric cars."

Auto Trader Insight is mentioned as part of the group that produced the battery health study. The point is that it’s based on real testing, not just rumors.

Concept

used battery electric vehicle (BEV) battery degradation scare stories

"And one of the great worries and concerns is about battery health in used electric cars. And it's kind of a myth. So let's just get going with it."

The segment is addressing a common fear that used EV batteries “degrade” quickly enough to make the car’s range unusable or require a very expensive replacement. The hosts frame this as a myth versus what large-scale testing shows.

Term

state of health

"Here's the headline result. Average battery health, state of health across the entire fleet, 95.15%. Let me sit with that for a second. The average across 8,000"

State of health is a number that estimates how much battery capacity is left compared to when it was new. Higher SoH generally means more usable range.

Term

annual degradation rate

"Annual degradation rate across the whole sample came out at 2.3% per year. So a car that's four or five years old... is sitting in a median state of health of 93.5%."

Annual degradation rate is how fast the battery’s capacity drops each year. If it’s low, the battery is wearing out more slowly.

Concept

used EV battery health still matters

"Now, I'm not saying every used EV is fine. There's real variance in the data and generational are quite clear that the spread is widening as vehicles age. A 10% state of health reading on an older car is rare, but it exists."

The point is that EV batteries don’t all age the same. Even if most used EVs look good, some individual cars can have worse battery health than average.

Term

battery health certificate

"If you want to check the specific car you're looking at, ask the dealer for a battery health certificate. Most manufacturers can produce a diagnostic showing current battery capacity as a percentage of original."

A battery health certificate is documentation provided by the manufacturer or dealer that reports the battery’s current capacity (often as a percentage of original). It’s used to verify the battery’s condition before purchase.

Term

diagnostic

"Most manufacturers can produce a diagnostic showing current battery capacity as a percentage of original. Anything above 80% is considered healthy."

Here, a diagnostic means running a battery check that estimates how much capacity the battery still has. The result is usually shown as a percentage of the original battery.

Term

BEVs

"That's a 59% increase on April last year. BEVs, battery electric vehicles, hit 26.2% market share."

BEV means a battery-electric car. It runs on electricity from a battery, not gasoline.

Concept

market share

"BEVs, battery electric vehicles, hit 26.2% market share. More than one in four new cars sold in April was electric."

Market share is how big a slice of new car sales a type of car gets. Here, it’s the share of new cars that are electric.

Concept

year on year growth

"And when you look at April's 59% year on year growth, [372.4s] there's something real happening here."

Year-on-year growth means “this year compared to the same time last year.” It helps show if things are really increasing, not just changing with the calendar.

Company

SMMT

"But I want to give you the full picture because the SMMT, [378.7s] that's the Society of Motor Manufacturers and Traders, they actually revised their 2026 forecast down this week."

SMMT is an industry group that monitors car sales in the UK. They update forecasts for how many EVs are expected to be sold.

Term

ZEV mandate

"And they've pointed to the ZEV mandate as a pressure the market's feeling more than it's responding to. What that means in plain English, manufacturers have to sell a certain percentage of electric cars or face fines."

A ZEV mandate is a government rule that makes car companies sell a certain number of zero-emission cars. If they don’t, they can get fined.

Concept

incentives

"Whether those buyers were going to switch, make the switch anyway, or whether they've been pulled forward by the incentives is harder to unpick."

Incentives are money-saving deals that make EVs cheaper to buy. They can make people buy sooner than they otherwise would.

Company

Renault

"There's another story underneath the mandate numbers. Renault reported this week that EV inquiries have risen 42% since the start of the Iran conflict at the end of February."

Renault is a car company. In this segment, they share UK data showing more people are asking about EVs and that EVs are a big part of their registrations.

Term

charging infrastructure

"more EVs on the road means more used EVs coming, more charging infrastructure justified,"

Charging infrastructure is the network of charging stations for EVs. If there are more chargers, it’s easier to own an electric car.

Term

plug-in hybrids

"Electrified vehicles overall, BEVs, plug-in hybrids, full hybrids hit 53.2% of all new registrations in April,"

A plug-in hybrid uses both electricity and a gasoline engine. You can charge it at home or at a charging station using a plug.

Term

full hybrids

"Electrified vehicles overall, BEVs, plug-in hybrids, full hybrids hit 53.2% of all new registrations in April,"

A full hybrid uses a gas engine and an electric motor together. You usually don’t plug it in—the battery charges as you drive.

Car

Toyota Hilux electric

"Okay, we're into Story 3, the electric Hilux. This is a new Toyota electric vehicle that's just come out... There it is, the Toyota Hilux electric, battery electric vehicle. It's interesting because this is a pickup."

This is a Toyota Hilux pickup that runs on electricity instead of a traditional engine. The big idea is using an electric powertrain in a truck that people normally use for hauling and tough jobs.

Term

plug-in van grant

"Orders open in June, priced with the plug-in van grant because it qualifies as a commercial vehicle, 52,845 pounds. Without the grant, 57,845 pounds."

The plug-in van grant is a government discount for certain plug-in vehicles used for work. In this segment, it’s the reason the price is lower when the car qualifies.

Term

light commercial vehicle

"That grant is worth 5,000 pounds and it applies here because the Hilux is classified as a light commercial vehicle. It's not classed as a car."

A light commercial vehicle is a category for smaller vehicles used for work. Here, that category matters because it can make the EV qualify for a government grant.

Term

kilowatt-hour battery

"The powertrain is a 59.2 kilowatt-hour battery, front and rear electric motors, permanent all-wheel drive."

kWh is how much energy the EV battery can store. More kWh usually means the car can potentially drive farther, but it depends on how efficiently the car uses that energy.

Term

permanent all-wheel drive

"The powertrain is a 59.2 kilowatt-hour battery, front and rear electric motors, permanent all-wheel drive."

Permanent AWD means the car sends power to all four wheels all the time. That can help with grip on wet, snowy, or rough surfaces.

Term

WLTP range

"The powertrain is a 59.2 kilowatt-hour battery, front and rear electric motors, permanent all-wheel drive. WLTP range and this is where we need to have a conversation is 150 miles."

WLTP range is a standardized test number for how far a car can go on a charge. Your real range may be different in everyday driving.

Term

towing capacity

"then 150 miles is a problem. Towing capacity is 1600 kilograms. Payload is 715 kilos."

Towing capacity is the maximum weight a vehicle is rated to pull safely. The segment contrasts the electric Hilux’s towing capacity (1600 kilograms) with the diesel’s much higher rating (3500 kilograms), showing why the EV may struggle on heavy, long-distance work.

Term

Payload

"Towing capacity is 1600 kilograms. Payload is 715 kilos. For context, the diesel version of the same truck tows 3500 kilograms and carries 1000 kilograms of payload."

Payload is how much weight you can load into the truck for work. They’re comparing the electric version’s lower payload to the diesel version’s higher payload.

Car

Ram 3500

"...ontext, the diesel version of the same truck tows 3500 kilograms and carries 1000 kilograms of payload. ..."

The Ram 3500 is a large pickup truck made for heavy work like towing trailers and carrying loads. The podcast mentions the diesel version because it can tow a lot and carry a lot of weight. That’s the main reason it’s relevant to a conversation about vehicle capability.

Term

Multi-terrain select

"What Toyota deserve credit for here is the off-road system. Multi-terrain select is still there."

Multi-terrain select is a set of off-road driving modes. It helps the truck adapt its traction and power delivery to different surfaces like dirt or rough ground.

Term

torque control

"Electric motors give you the extraordinary torque control at low speeds, actually better suited to slow technical off-roading than diesel in some ways."

Torque control is how smoothly and precisely the vehicle can apply pulling force. The hosts are saying electric motors can manage that force really well at low speeds, which helps when crawling over rough terrain.

Term

DC charging speed

"The DC charging speed is rated as best in class for this segment. So when you do need to rapid charge, it's quick."

DC charging speed is how fast the car can charge on a fast-charging station. If it’s quick, you can add enough range during a busy day instead of waiting for a full overnight charge.

Concept

fleet of service vehicles

"but if you've got a fleet of service vehicles doing short daily rounds, if you're operating from a fixed base, if you're a council or a utility company trying to electrify your commercial fleet..."

A fleet of service vehicles is a company’s set of work trucks. The idea here is that EVs make more sense when the routes are predictable and the vehicles can charge at the same place every day.

Term

fixed depot

"and if they've got fixed depot, I think that's the important number to look at here. And if you've"

A “fixed depot” is a home base location where the vehicle stays most of the time. If you can charge there reliably, the EV is much easier to run for work.

Term

fast kilowatt DC charging

"And if you've got access to fast kilowatt DC charging somewhere, then the car is going to charge quickly for you."

DC fast charging is the kind of public charging that can add a lot of energy quickly. It’s usually faster than charging at home or at a normal outlet.

Car

Volkswagen Golf

"Right, next up is segment four and we've got the squeeze. The VW Golf EV and the road charge."

The Volkswagen Golf is a very common car, and an electric “Golf EV” would be the electric version of that everyday model. The episode is saying Volkswagen isn’t bringing it out on the timeline people expected.

Term

road charge

"The VW Golf EV and the road charge. I think this is quite an interesting story. It's the Golf EV that won't happen and the road charge that will happen."

A “road charge” is a government fee for driving on public roads. It can matter more as cars switch from petrol/diesel to electric, because fuel taxes may no longer apply the same way.

Car

Volkswagen Id3

"Volkswagen confirmed this week that there will be no electric Golf in 2028. The ID3 NEO is coming."

The ID.3 is Volkswagen’s electric hatchback. “ID3 NEO” here means a newer version that Volkswagen is planning to bring out instead of an electric Golf.

Concept

cannibalise

"Or that the ID3 NEO is close enough that they don't want to cannibalise it."

“Cannibalise” here means one car model might steal buyers from another model in the same company’s lineup. The idea is that selling an EV Golf could reduce sales of the ID.3.

Term

EVD

"Story two that links to this, we think, is the EVED that's coming... This is the mileage-based road charge for electric vehicles, announced in the autumn budget and arriving April 2028."

EVD is a new kind of road charge that’s based on how many miles you drive. Instead of being built into fuel prices, it would be charged per mile for EVs.

Term

fuel duty

"the average petrol car driver is currently paying somewhere between £900 and £1200 a year in fuel duty alone... as the fleet continues to electrify and the government needs to replace the fuel duty revenue it's losing."

Fuel duty is the tax included in the price of petrol and diesel. If more people drive EVs, the government collects less of this tax, so it looks for other ways to fund roads.

Concept

OBR forecast

"The OBR estimate, the EVD, will cost the average EV driver about a fifth of that... The OBR forecast that the EVED will result in nearly 440,000 fuel EVs sold by 2031."

The OBR is a UK government watchdog that makes forecasts about money and the economy. In this segment, they’re used as the source for an estimate of future EV sales.

Concept

fuel EVs

"The OBR forecast that the EVED will result in nearly 440,000 fuel EVs sold by 2031. Some of that will be offset by other measures..."

The phrase “fuel EVs” doesn’t sound like standard EV wording. Based on the context, they’re talking about how many EVs (electric vehicles) could be sold in the future.

Term

public charging

"Keep an eye on the rates and see what they're doing for public charging and so on."

Public charging is charging your EV at stations that aren’t in your driveway—like at shops or along roads. If you can’t charge at home, these stations matter a lot.

Brand

B&Q

"Okay. Let's go to the B&Q story. So B&Q gets £11 million of EV chargers."

B&Q is a UK store. In this story, they’re putting EV charging stations in their parking lots so drivers can charge while they shop.

Term

EV charge points

"Raw charging and B&Q announced an £11 million roll out of EV charge points across B&Q car parks nationwide."

EV charge points are the individual charging stations you plug into at a site. The number and placement of charge points affects queueing, availability, and how reliably drivers can top up when they’re parked for shopping or errands.

Company

Raw charging

"Raw charging and B&Q announced an £11 million roll out of EV charge points across B&Q car parks nationwide."

Raw charging is the company building and running some of the EV chargers. They’re expanding chargers into places like retail parks, not just on highways.

Concept

dwell time location

"Because B&Q is not a destination in the same way as a motorway service station. It's a dwell time location. You go, you spend 45 minutes to an hour, you come out."

It means a charging spot where you’re parked for a while, like while you shop. Because you stay there, the car has time to add enough battery range to matter.

Concept

charging network

"That is exactly the category of charging that makes electric car ownership work for people without home charging. The retail park is the gap in the charging network that nobody really talks about."

A charging network is the set of charging places around an area. If there are more chargers where you already stop (shops, gyms), it’s easier to plan trips and less stressful.

Car

Dodge Charger

"...g about supermarket charging. I went and filmed a charger down in Devon that was sitting, it was an old Pow..."

The Dodge Charger is a car model made by Dodge, usually known for being a bigger, performance-focused sedan. In this podcast, it’s brought up because the host is talking about a charging point labeled “Charger” that they found in Devon. That means it’s about charging equipment, not the car itself.

Term

PowerPoint charger

"I went and filmed a charger down in Devon that was sitting, it was an old PowerPoint charger, sitting in a Sainsbury's"

This sounds like an older, simpler kind of charging setup. The host is basically saying it didn’t look like one of the newer, high-speed chargers.

Brand

Tesco

"I went and filmed a charger down in Devon that was sitting, it was an old PowerPoint charger, sitting in a Sainsbury's or no in a Tesco car park actually I think at the time in North Devon"

Tesco is a supermarket brand mentioned as the place where the charger was located. It supports the idea that charging is showing up where people already park to shop.

Brand

Sainsbury's

"I went and filmed a charger down in Devon that was sitting, it was an old PowerPoint charger, sitting in a Sainsbury's or no in a Tesco car park actually"

Sainsbury's is a supermarket brand mentioned in the story about where a charger was found. The point is that chargers are often in places like grocery store parking lots.

Term

kilowatt charging

"been used in years. So I did a film. It's got seven kilowatt charging on it and everyone is commenting"

It’s basically how fast the charger can refill your EV’s battery. The higher the number (kW), the faster it can charge—assuming the car can accept that speed too.

Term

off-street parking

"in North Devon or you have enough space for off-street parking so you're probably going to charge at home"

It means you can park at home somewhere you control. That matters for EVs because it makes it easier to charge at home instead of relying on public stations.

Term

PowerPoint charging

"and why did they take away all the free PowerPoint charging when they put it in originally?"

This sounds like charging from a normal outlet at a place you can plug into. It’s usually slower than the fast public chargers.

Term

tethered

"It doesn't have a case, it's not tethered so you have to get the cable out of your car, plug it into the PowerPoint charger"

“Tethered” means the charger has the cable attached to it. You just plug the car in, instead of taking a cable out of your own car.

Term

destination charging

"and I'm looking forward to finding out more about what raw charging and doing with B&Q because that's a massive investment are going to be interesting and I hope are going to be more based on destination charging and dwell time at charge points because that's the key thing around using these electric cars."

This is charging while you’re parked somewhere for a while, like shopping or at work. Since you’re not in a hurry, you can charge more easily without needing super-fast chargers.

Term

DC in there

"so getting a quick squirt of DC in there and adding 100 miles range sorts you out for the week"

They mean a short fast-charge stop to add enough range for your week. It’s like topping up quickly so you don’t have to charge every day.

Concept

lease returns wave hitting the market simultaneously

"The main pressure was a wave of 2020 to 2022 lease returns hitting the market simultaneously that wave is moving through the sweet spot right now"

A lease returns wave is when many EVs from earlier lease terms come back to dealers at the same time. When that happens, supply can temporarily increase and push used prices down until the market works through that inventory.

Term

battery certificate check

"our lead story today was about battery health being at 95% so get a battery certificate check the car should be fine."

A battery certificate check is a verification process that documents the EV battery’s condition—typically including measured state-of-health figures. It’s used to confirm whether the battery degradation is within expected limits before buying a used EV.

Concept

EVED

"Question two does the EVED mean buying an EV is now a worst financial decision. The running cost numbers still work"

EVED appears to be a shorthand used in the episode for an EV-related financial metric or decision framework—here, framed as whether buying an EV is a “worst financial decision.” Because the transcript doesn’t expand the acronym in this slice, listeners may need the show to define what EVED stands for and how it’s calculated.

Term

rapid charging

"it gets more complicated is if you're doing high mileage and mostly rapid charging publicly. Home charging means that remains the financial engine"

Rapid charging refers to faster public charging (typically higher power DC charging) compared with slower home charging. It can affect both costs and battery wear patterns, which is why the episode distinguishes it from charging overnight at home.
