This is how electric cars must never be charged, warns an expert

Electric car owners must never let the battery drop to 0 percent. It wears down the battery pack unnecessarily, says an expert.

In the vast majority of cases, you no longer get into an electric car when 0 is written next to the battery percentage. There is 0 range left. And that's a really bad idea.

Especially if you just leave the car idle. That's what Benny Christensen says, who is a technical consultant in the Norwegian answer to FDM, NAF.

In fact, Benny Christensen compares leaving the car to a dead battery with frequent lightning charging. Both parts wear out the battery pack faster.

– There will be battery wear, in the same way as when you fast charge too often. The battery is unlikely to be damaged. But we do not recommend that the battery is empty. Something is happening to the chemistry in the battery.

According to NAF, a normally functioning battery pack in an electric car loses around 1 to 2 percent current over the course of 24 hours when the car is just standing still.

If you are therefore going to be away from the car for a longer period of time, or do not use the car for a period of time, it may for the same reason be a good idea to check how much current is in the battery.

And if you are away from the electric car for more than five months, you should connect the car to a charging station, which can take care of maintaining the battery. In those situations, the voltage on the battery should always be somewhere between 50 and 60 percent. A car brand like Tesla recommends exactly the same.

– If the battery charge level drops to 0 percent, connect to the power supply. If you leave the car disconnected for a long period of time, it may no longer be possible to charge the car.

– It may be that you have to use a jump starter or replace the 12 volt battery to get started again, says Tesla.
