Electric vehicle is a kind of travel tool that is often encountered, and its structure is relatively simple. The key components of electric vehicle include frame, motor, battery and regulator. The function of the regulator is to adjust the circuit of the whole vehicle. If there is no regulator, the electric car can't run normally. Most regulators will be fixed under the back seat. Motor is the power source of electric vehicle, which can drive the vehicle forward. Battery is a component used to store electric energy in electric vehicles, which can supply power for all electronic devices in electric vehicles. The battery is a wearing part and needs to be replaced regularly. With the increase of charge and discharge times, the performance of the battery may also decrease continuously.

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 may also decrease, and of course the performance of the battery may also decrease. If you can maintain accurate car habits, you can still effectively extend the service life of the battery. When charging, a suitable charger must be used, and overcharge and overdischarge of the battery must be avoided. When you use the car at ordinary times, you must charge the battery regularly, otherwise the battery will be dead.
