The working principle of the car battery wire is based on electrochemical reactions. Automotive batteries usually use lead-acid batteries, which are composed of positive plate (lead dioxide), negative plate (lead) and electrolyte (dilute sulfuric acid). During the charging process, the current from the external power source converts the lead dioxide on the positive plate to lead sulfate, while the lead on the negative plate is converted to lead sulfate, and this process converts electrical energy into chemical energy for storage. In the discharge process, lead sulfate is re-converted into lead dioxide and lead, and chemical energy is converted into electrical energy to power the electrical equipment of the vehicle
Starting function : When the vehicle starts, the battery starts the engine by providing an instantaneous high current. The battery instantly releases a large amount of electric energy, which drives the engine to run by starting the motor, thus starting the vehicle
power supply function : when the engine is not running, the battery provides electric energy for the vehicle's electrical equipment, such as lights, audio and so on
convenient maintenance : understanding the working principle of the battery is helpful to correctly judge the status of the battery, rationally arrange the use of the vehicle, choose the appropriate charging method, so as to extend the service life of the battery
