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 controller is usually fixed under the back seat.
It is the power source of the motor and is responsible for driving 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.
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 will continue to decline.
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.
