How Heat Affects Electronic Cars And How To Protect Them

Many of us know that petrol and diesel cars and heat do not mix very well, but rising temperatures can have even more of a detrimental effect on electric cars.

Experts at ElectricalDirect explain how the UK heatwave could be affecting electric vehicles, and how to prevent issues.

The battery life of most electronic devices is compromised and less effective when exposed to higher temperatures, and electric cars are no exception, with a study conducted by GeoTab on 6,000 electric vehicles¹ showing that the capacity of an electric car battery is reduced when driven in hot weather.

As well as this, tyre pressure can be affected on all types of vehicles in warmer weather, and with electric vehicles often being heavier than standard vehicles, tyre pressure could be diminished further.

How to prevent issues

1) Park your electric vehicle in the shade

Parking any vehicle in the shade during hot weather is best practice, but it is particularly important for electric vehicles to be kept cool to ensure optimal function of their lithium-ion batteries. If this is not possible, taking other preventative measures to keep your vehicles temperature down such as a sunshade for your windscreen will help.

2) Avoid driving between 12pm and 3pm

Just like we are all advised to avoid being directly in the heat when it is at its most powerful, the same goes for your electric vehicle. This will help to make the most of your vehicle’s energy and range, as well as preserving the vehicle’s tyre pressure.

3) Charge your vehicle to 80%

Electric vehicles share the same type of battery as other portable electronic devices such as laptops and smartphones, meaning that these devices run the risk of being overcharged. Overcharging is often coupled with overheating, which when combined with increased temperatures, elevates the chance of damage occurring. Therefore, only charging your vehicle to 80% capacity will significantly reduce this risk.
