you can't get a card without my name, so friends need to pay attention. Electric vehicle is a common travel tool, and its structure is very 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. Without the regulator, the electric vehicle can't run normally. Most adjusters will be fixed under the rear seats. The motor is the power source of the electric vehicle, which can drive the electric vehicle forward. Battery is a part of electric energy stored in electric vehicles, which can supply power to all electronic devices on electric vehicles. However, the battery is also a fragile part and needs to be replaced regularly. With the increase of charge and discharge times, the performance of the battery may also decrease. During the charging and discharging process, 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. Encourage friends to use a suitable charger when charging, and be sure to avoid overcharging the battery. Overcharging will damage the battery. Encourage friends not to charge the battery just after riding.
