What are the components of automotive electrical equipment and what are their functions?

Power supply equipment and electrical equipment.

1. The power supply includes storage battery, generator and voltage regulator, and its function is to supply power to the electrical equipment of the whole vehicle.

1, the main function of the battery is to start the engine. When the engine is not working, it supplies power to the electrical equipment of the whole vehicle.

2, the role of the generator When the generator is running above idle speed, it replaces the battery to supply power to all electrical equipment except the starter, and at the same time charges the battery.

3. The voltage regulator is mainly used to automatically maintain the output voltage of the generator when the engine speed and load change to ensure safe work.

Second, there are many kinds of electrical equipment with different functions, which can be divided into ignition device, starting device, lighting and light signal device, instrument and auxiliary electrical device according to their functions.

1, the starting device is powered by the battery, which converts the electric energy of the battery into mechanical energy to drive the engine to rotate and start the engine.

2. The ignition device generates high-voltage electricity according to the working sequence of the engine, and the spark plug ensures the accurate ignition of the mixed gas in the cylinder.

3. Lighting and lighting signal devices ensure the safety of the car at night, in rain and fog, and various types of lighting tools are installed on the car. There are mainly front lighting, front small lights, taillights, license plates and fog lights.

4. In order to ensure the driving and parking safety of the car, various signal lights can be installed on the car, and the instruments respectively display the state parameters of various parts of the car, such as engine water temperature and oil pressure. Residual fuel, speed, etc.

5. Auxiliary electrical equipment includes wiper, heater, air conditioner and other auxiliary tools.

Extended data:

The first charge of the battery is called initial charge, which has a great influence on the service life and charging capacity of the battery. If charging is insufficient, the charging capacity of the battery is not high and the service life is short. If the battery is overcharged, its electrical performance will be good, but it will also shorten its service life, so the new battery should be charged carefully.

For dry-charged lead storage batteries, according to the instruction manual, if they need to be used within the specified two-year storage period, they can be put into use without charging as long as the electrolyte with the specified density is allowed to stand for 15min. However, if the storage period is more than two years, due to the partial oxidation of the electrode sheet, it should be recharged before use and recharged for 5 to 8 hours before use.
