Off-peak electric vehicle (EV) charging across fast, rapid and ultra-rapid public charging fell by up to 28% in December, according to the latest AA EV Recharge Report. 

It came after one charge point provider reverted to offering a flat rate tariff across the day, rather than varying prices.

Jack Cousens, head of roads policy for the AA, said: “December saw a huge reduction in public charging prices, particularly at the quickest speeds.”

An AA survey of more than 14,600 drivers found that 60% of EV drivers use the total cost to recharge their car as their main metric, followed by 30% who use pence per kilowatt hour (p/kWh).

For petrol and diesel drivers, two thirds (66%) use the cost to fill the tank as their main method of tracking fuel spend, with 30% using miles per gallon (MPG). 

Only one in 25 (4%) use pence per mile (ppm) to monitor their fuel spend.

Interestingly, 16% of drivers said they don’t monitor how much they spend on recharging or refuelling their car

Eight out of 10 drivers believe forecourts outstrip EV devices

In the same poll, 80% of drivers believe there are more fuel stations, whereas just 6% felt there are more EV devices than forecourts.

While there are 8,329 forecourts across the UK, there are more than 37,000 public charging locations where drivers can plug in. 

There are 108,410 publicly available EV connectors, with more installations going live each month. 

However, the total number of publicly available chargers is only one aspect that combustion drivers are concerned about, according to the AA. 

Many cite the difference in time taken to refuel compared to recharging as a reason for deferring their transition to electric, as well as the inability to charge at home as they don’t have dedicated off-street parking. 

Cousens said: “As drivers reveal that they monitor the cost to ‘fill the tank’ to gauge fuel spend, drivers could save more than 50% with an EV compared to petrol.

“However, the public are still unclear as to how well the charging network is growing across the UK. 

“While there are certainly more charging sites than fuel forecourts, more are needed, and the positive message of the expanding the charging network needs to be understood in the public mindset.”

He added: “There is still work to do to help convince drivers to make the switch to EVs.

“While the number of publicly available chargers is only one factor, petrol and diesel drivers have other concerns that need alleviating first before swapping the pump for a plug. 

“The time taken to charge versus putting fuel into a car still remains an important consideration for those unsure about making the switch, however, the reality is that any driver should take a break after two hours driving which would give adequate time to charge up.”
