Brits who own an electric vehicle (EV) have been advised to follow one rule when charging their cars in the coming days to protect their motor’s battery health and charging speed
Brits with electric vehicles (EVs) are being urged to follow one simple rule when charging their cars this weekend, or risk damaging their battery.
There’s no denying the UK EV market is booming, with 29,634 new Battery Electric Vehicles (BEVs) — cars powered entirely by the electricity stored in a battery, as apposed to hybrids, which also use petrol engines — sold in January 2025 alone, and one in three used EVs now being available for under £20,000.
This surge in new and used EVs means more drivers than ever are plugging in and making the switchover to greener motoring. As the EV revolution accelerates, experts are keen to ensure drivers get the most from their motors, particularly as the summer season brings fresh challenges for charging and battery care.

Richard Evans, head of technical services at webuyanycar, has therefore shared some essential advice for EV owners about charging this weekend. The expert pointed out that the temperature of the location where you charge your car can make a big difference, stating: “On hot days, heat can slow your EV’s charging or damage the battery if not properly managed.
“This applies to temperatures above 30°C. Optimal charge temperature is 15 to 25°C.” This advice isn’t just relevant during heatwaves, as freezing temperatures can also trouble the efficiency of charging an EV’s battery.
Richard added: “Cold weather can also have the same effect as heat, resulting in a slower charge. During the summer months, it’s best to charge your car in the shade and avoid fast charging repeatedly to reduce extra strain on the battery.”

This advice comes at a crucial time, as forecasters predict that the UK is set for a spell of unusually high temperatures this weekend, continuing into next week. The Met Office announced another incoming heatwave, with conditions set to remain sweltering for some time.
This Friday — July 11 — is predicted to be the hottest day of the scorching run, with the mercury likely topping out at 32°C across the southeast of England and parts of the east coast. But nearly everywhere in the UK, including vast areas of Scotland, Wales and Ireland will see an extended spell of extreme heat.
So as Britains gear themselves up for another heatwave, EV owners are being urged to seek out shaded spots or covered charging bays, whether at home or at public stations. By following expert advice and charging in the right place, drivers can protect their batteries, ensure reliable performance, and make the most of their EVs as the temperatures rise.
