Thanks to their convenience and environmental friendliness, electric vehicles are widely loved by consumers and can be seen on every street. But with constant use, many headaches appear. For example, the self-discharge of an electric vehicle has become a problem that troubles everyone. So why does an electric vehicle battery lose charge? The Xupai team explains:

First: storing the battery discharged for a long time.

An electric vehicle should be fully charged before being left in storage, because storing it in a low state of charge seriously shortens its service life, and the longer it sits idle, the worse the damage. This also makes the battery lose more charge.

Second: high-current discharge.

An electric vehicle should avoid carrying overly heavy loads, and you should pedal to assist when starting off and climbing slopes. At such moments the motor current grows, the battery discharges too fast, and the voltage drops quickly, which greatly damages the battery.

Third: the battery chronically short of charge.

The battery is often left half-hungry. Many riders get into the habit of charging only when the battery is almost empty. In fact, riding the electric vehicle every day, whether for 10 km or 50 km, you should charge it in time so that the battery stays in a fully charged state.

Fourth: no periodic deep discharge.

The correct method is to perform a deep discharge once every two months, that is, ride a long distance until the low-voltage indicator flashes and the power runs out, and then recharge to restore the battery capacity.

That is all for the causes of battery self-discharge. We hope this helps. To learn more about electric vehicles, you can follow the Xupai official account.
