What are the main components of automobile electrical system?

Automobile electrical system consists of seven parts, namely: charging system, starting system, ignition system, lighting and signal system, instrument system, auxiliary electrical system and electronic control system. 1. The charging system consists of storage battery, voltage regulator and alternator, which mainly provides the power needed for the system to work when the car starts and runs. 2. The starting system consists of battery, ignition switch, starter and its control circuit, which mainly provides starting torque for the engine to make it run normally. 3. The ignition system consists of ignition coil, spark plug, spark plug number generator and distributor assembly (distributor-free ignition system is a microcomputer control unit), which is used to ignite the mixed gas in the cylinder and provide power for the engine. 4. Lighting and signal system includes lighting system and signal system. The lighting system includes headlights, fog lights, position lights, license plate lights, luggage compartment lights, overhead lights and other lighting lights, which are used to help drivers obtain external road information when driving at night or in bad weather. The signal system includes turn signal lights, danger warning lights, brake lights, background lights and electric horns. , which is used to remind other drivers or pedestrians around to get information about driving vehicles and ensure traffic safety. 5. The auxiliary electrical system is composed of wiper system, electric window system, radio, low-temperature starting preheating device and cigarette lighter, which mainly improves the safety, comfort and stability of automobile driving. 6. The instrument and alarm system consists of oil pressure gauge, coolant thermometer, fuel gauge, speedometer and engine tachometer. It mainly provides the driver with information about the vehicle condition, helping the driver to find the vehicle problems in time and avoid accidents. 7. The electronic control system consists of engine control unit, brake locking device, electronic control suspension system, automatic air conditioner and electronic control automatic transmission. It interacts with sensors and actuators to control the system according to the optimal configuration parameters of the vehicle and ensure the normal operation of the module. The above is a brief introduction to the seven parts of automobile electrical system, and each part has its unique composition and function. Thank you for reading.
