Electric vehicle drivers are being charged more to top up their batteries on long journeys than people behind the wheel of petrol cars pay for fuel, according to new analysis.
The RAC said the average price of using rapid chargers on a pay as you go basis has increased by nearly 26p per kilowatt hour (kWh) since May, reaching 70.3p per kWh this month.
This rise – caused by the soaring wholesale costs of gas and electricity – means drivers pay around 20p per mile for their electricity when using the chargers.
It’s vital that the numbers stack up— Simon Williams, RAC
The per mile cost for a petrol car achieving an economy of 40 miles to the gallon is just 17p.
The equivalent cost for drivers of diesel cars is 20p per mile.
Most electric car owners predominantly use slower chargers at home, which cost less than half the price of public rapid devices.
But those taking longer trips beyond the range of their car’s battery depend on rapid and ultra rapid public chargers to complete their journeys.
RAC spokesman Simon Williams said: “For drivers to switch to electric cars en masse, it’s vital that the numbers stack up.
“In time, the list price of new electric models will come down but charging quickly has also got to be as affordable as possible.
“It continues to be the case that those who can charge at home or at work and who don’t use the public charging network very often get fantastic value – even given the relatively high domestic energy prices right now.
There’s no question they have to pay far more, and in some cases more than petrol or diesel drivers do to fill up on a mile-for-mile basis— Simon Williams, RAC
“Sadly, the same can’t be said for people who either can’t charge at home or at work, or who regularly make longer journeys beyond the range of their cars.
“There’s no question they have to pay far more, and in some cases more than petrol or diesel drivers do to fill up on a mile-for-mile basis.”
Figures published by the Society of Motor Manufacturers and Traders show battery electric new cars took a market share of 16.6% in 2022, surpassing diesel for the first time to become the second most popular powertrain after petrol.
Some 22.9% of all new cars registered were plug-in vehicles, which includes pure electrics and plug-in hybrids.
Sales of new petrol and diesel cars and vans in the UK will be banned from 2030.
