Vehicle electrical system
The vehicle electrical system is designed to provide power and control to various electrical and electronic systems and devices, such as:
* Engine
* Lighting
* Heater
* Sound system
* Electric windows
* Security systems
Components of the electrical equipment system:
1. Battery
* Provides electrical energy when the engine starts and powers electrical systems when the engine is not running.
2. Generator
* Charges the battery and provides power to electrical systems when the engine is running.
3. Electric starter
* Starts the engine.
4. Electrical wiring
* Connects electrical components and ensures the transmission of electricity.
5. Fuses and relays
* Protect electrical systems from overload and short circuit.
* Control turning electrical devices on and off.
6. Switches and switches
* Control lighting, power windows and other electrical devices.
7. Electrical control unit
* Controls various electrical systems, including the engine, lighting and sound system.
8. Ground terminals
* Provide electrical contact between components and the vehicle chassis.
9. Car computer (ECU)
* Controls the operation of the engine and transmission, as well as other electrical systems.
Operating principle of the electrical equipment system:
1. The battery provides electricity to the starter to start the engine.
2. Once the engine starts, the alternator begins to charge the battery and power the electrical systems.
3. Electrical wiring carries electricity from the generator and battery to various electrical devices.
4. Fuses and relays protect electrical systems from damage.
5. Switches and switches control the turning of electrical devices on and off.
6. The electronic control unit controls various electrical systems and devices.
