What are the components of the car power system?
The battery is a reversible DC power supply. The most widely used starter battery in the car is in parallel with the engine to power the electrical equipment. The role of the battery is: when the engine starts, to start the engine and ignition system of power supply in power or not; start the machine under the condition of low voltage power supply to electrical equipment; when the number of electrical equipment and access, generator overload, assist the generator power supply; when the electric batteries keep not enough, but also less load generator when it can be a generator store energy into chemical energy. Therefore, it occupies an important position in the car. How to correctly use and maintain the battery is very important for prolonging the service life of the battery. Therefore, the automobile repair factory should be responsible for the maintenance, repair and opening of new batteries and other projects.
The generator is the main power supply of the automobile electric system. It supplies all the power equipment except the starter when it is working normally and charges the battery to supplement the electric energy consumed by the battery in use.
It includes battery, generator and regulator. Among them, the generator is the main power supply. When the generator is working normally, the generator supplies power to the whole vehicle electrical equipment and charges the battery at the same time. The function of the regulator is to keep the output voltage of the generator constant.
DC generator matching regulator is generally composed of voltage regulator, current limiter, cut-off relay three parts. The alternator regulator can be greatly simplified. Because the silicon diode has unidirectional conduction characteristic, when the generator voltage is higher than the accumulator motive force, the diode has prevented the reverse current the function, therefore the alternator does not need the cut-off relay.
Hello, the engine power supply system mainly has generator, battery, voltage sensor, AC generator management module, I hope my answer can satisfy you, I wish you a happy car!
