Help your electric battery keep the cold at bay

Published by on 02.11.2019 - 3 min

Extreme winter temperatures can negatively impact the performance of your electric car’s battery. Follow our advice to maximise your battery’s life - even if it’s minus 20°C - by taking advantage of all the features your car offers.

Why are electric car batteries less efficient in extremely cold temperatures?

Maintaining a constant temperature is a requirement for the proper operation of your electric car’s battery. In winter, the cold reduces the performance of the battery, both in terms of its range and its charging capacity.
In winter conditions, the use of your vehicle’s heating system is another factor that impacts your electric car’s range. Luckily, smart solutions exist to limit your car’s energy consumption, even in very cold weather.

A battery’s life: the little things that make a big difference

First, it is recommended that you charge your battery 100% before departing. This will offer you greater range knowing that the heating system will be turned on, even though the use of pre-conditioning is strongly advised. Available for ZOEs and Kangoo Z.E.s, this feature lets you program the heating system from your smartphone or hands-free card before you hit the road.

If pre-conditioning is initiated while the car is connected to a power supply, the energy necessary to heat the interior will come directly from the electric grid and the range of your electric car will not be affected. That way you can drive having an easy mind!

Once on your way, select the “ECO” mode to automatically optimise your energy consumption, especially if you’re planning a long trip. This feature will allow you to gain up to 10% more range.

Drive smoothly

Aside from switching to “ECO” mode, your driving can also have a strong impact on your energy consumption. If you tend to enjoy the ZOE’s aggressive acceleration, that can have an impact on energy use. With the arrival of snow, ice and fog, take advantage of wintertime to try out an eco-driving style. The more you avoid sudden stops and starts, the more you will save your battery’s energy! Anticipating your next move is still your best choice when it comes to a smooth ride and will reduce your vehicle’s energy consumption.

And as for regenerative braking, it rounds out your vehicle’s energy use optimisation. It allows you to store energy during the most acute moments of braking or deceleration. This energy recovery braking system, developed by Renault, converts kinetic energy into electricity. It can recover up to 20% of electric car range!

At the end of your journey, and if you have the option, it is advised that you park your electric vehicle in a garage or other enclosed space to shield it from temperature changes.
