BERLIN: While many gained a sense of security, even satisfaction, through filling up the tank of a vehicle with a combustion engine, things are a little different when it comes to electric cars.
You shouldn't charge your EVs battery to 100% of its capacity, according to experts at TÜV Thüringen, a German technical inspection association.
Some modern charging systems limit charging to 80%, which is usually sufficient for everyday use. If you are taking a longer trip, on the other hand, you should enable full charging, as this is the only way to cover a long distance.
That will keep your battery healthy as long as it doesn't become a habit. Generally, try to prevent the charge from dropping below 10%, to avoid accelerating the reduction in capacity.
Another no-go: frequent fast-charging. Instead, try to charge your car's battery at a gentle pace at home or at public charging stations with 11 to 22 kW.
The battery, which is after all your e-car's most vital organ, also doesn't like long periods of just sitting around or excessive cold or heat. If your car is parked for a longer period of time, make sure your battery is charged to between 30% and 70%, with the vehicle ideally kept in a garage.
Not only does every charging cycle put a strain on the battery, but according to TÜV Thüringen, the capacity also inevitably decreases over time due to age.
However, most manufacturers provide a guarantee for the battery, for example that after 160,000km or eight years of use, at least 70% of the original capacity is still usable.
