Flat tyres rather than flat batteries let EVs down – report

A flat tyre is the most common EV breakdown call-out.

So says United Kingdom-based breakdown provider Start Rescue, adding that EVs are less likely to suffer a flat battery than petrol or diesel cars.

It suggests an EV should be regularly used to keep its 12-volt battery charged.

“Our data shows 29% of electric car call outs are due to a flat tyre,” says Start Rescue managing director Lee Puffett.

“This is similar to petrol and diesel cars as many new cars no longer have a spare wheel fitted in order save weight and emissions, and larger puncture holes cannot always be repaired with foam sealant.”

Start Rescue’s data shows that EV battery range is not an issue for electric car drivers.

However, they still need to look after the 12-volt battery that powers the same functions as petrol and diesel cars such as the dashboard which enables the vehicle to start, as well as lights and wipers, it says.

A flat battery in EVs accounts for 23.7% of call outs compared to 29.7% for petrol and diesel, Start Rescue says.

“Regular use will keep the 12-volt battery in good condition and avoid breakdown call outs as EVs still need this system to open the doors and start,” it explains.

Puffett adds that EVs can be more complex to repair at the roadside – “our data shows a petrol or diesel car is twice as likely to be fixed at the roadside – so it is vital to look after your EV’s 12-volt battery”.

In a What Car? Survey of Best Breakdown Cover, Start Rescue came top for best response time, reaching 77% of call outs in 30 minutes to an hour and didn’t leave anyone waiting for more than two hours.

Start Rescue also won best in the survey for performing temporary repairs that let people continue with their journeys.

Launched in 2009, Start Rescue is an integral part of the UK’s fourth largest breakdown and recovery service, Call Assist, which has more than two million UK customers.
