Huang Ka is a formal license, and the white license is a temporary license. Electric vehicle is a common means of transportation, and its structure is relatively simple. The main components of electric vehicle include frame, motor, battery and controller. The controller is used to control the whole vehicle circuit. Without the controller, the electric vehicle can't run normally.

The motor is the power source of the electric vehicle, which can drive the electric vehicle forward.

Battery is a part of electric vehicle, which is used to store electric energy. The battery can supply power for all electronic devices on the electric vehicle.

If there is no battery, the electric car can't run normally.

The battery is also a vulnerable part that needs to be replaced regularly. With the increase of charge and discharge times, the performance of the battery will continue to decline, so it is necessary to replace the battery regularly.

During the charging and discharging process, the ions in the battery will move in the electrolyte, and some ions will react with the electrolyte when they move in the electrolyte.

With the increase of charge and discharge times, the number of ions in the battery will decrease continuously, so the performance of the battery will also decrease continuously.

If you can maintain the correct car habits, you can effectively extend the service life of the battery.

When charging, you must use a suitable charger, and you must prevent the battery from being overcharged.
