Slowest EV charging could cost the most – and MORE than petrol

The second EV Recharge report from the AA shows new peak and off-peak rates have increased the cost of charging an electric car.

The introduction of peak and off-peak rates by electric vehicle charging networks could make slow charging the costliest option for EV drivers. 

That is the message from the AA, which has just published its latest EV Recharge report, examining the charging market in December 2022. 

It finds that while slow charging costs fell by 17p per kWh since November 2022, the use of peak periods risks making it more expensive than ultra-rapid charging.

Peak hours at peak prices

Certain charging networks have introduced peak and off-peak hours for their 7kW chargers, in a bid to manage demand and usage. The aim is to allow power to be provided throughout the day, and prevent drivers charging for longer than necessary.

Not all operators have peak hours at the same times, meaning drivers need to pay particular attention when recharging. 

The AA’s research found networks charged an average of 72p per kWh to use a 7kW slow charger during peak times. By contrast, using the fastest ultra-rapid charging devices (in excess of 101kWh) cost only 70p per kWh. 

This means adding an 80 percent charge to a 50kW battery would cost £28.00 with an ultra-rapid charger at peak times, versus £28.80 with a 7kW device.

More price monitoring needed

These prices also mean using a slow 7kW charger at peak times costs 16.18p per mile driven. Yet with falling fuel prices, refilling a petrol car now costs only 14.45p per mile. 

The AA does note that many EV drivers will charge at home, however, reserving more expensive on-the-go options for a quick top-up.

Jack Cousens, head of roads policy and recharging for the AA, said: “The introduction of peak and off-peak charging mirrors many domestic energy providers’ offering to EV owners.

“We completely understand why this has been introduced as it allows the supply of electricity to remain constant throughout the day, while ensuring drivers don’t overstay their welcome.

“However the price gap between the two is staggering, so much like refilling a petrol or diesel car, drivers should check the rates they could be paying before plugging in.

“While pump prices are falling, electricity prices are going in the other direction, but we are hopeful prices could tail off later this year. The government must keep an eye on prices and act if necessary.

“Unlike fuel, EV charging already has a regulator in place to monitor public charging rates and they shouldn’t be afraid to step in if prices escalate.”
