Electricians in a car
The electrical system is a critical component of a modern vehicle, providing power and operation to various systems and components. Basic electrics in a car include:
Battery
* DC power supply to ignite the engine, power electronics, and provide backup power.
* Lead acid, gel or lithium ion.
Alternating current generator (alternator)
* Converts mechanical energy from the engine into electrical energy to charge the battery and power systems.
* Two- or three-phase, with external or built-in voltage regulator.
Starter
* An electric motor that runs a car’s engine.
* Battery powered, consumes high current.
Electronic control unit (ECU)
* The brain of the car, which controls the operation of the engine, transmission and other systems.
* Processes signals from sensors and issues commands to actuators.
Lighting systems
* Headlights, taillights, turn signals, brake lights, etc.
* Light-emitting diode (LED), halogen or xenon.
Infotainment system
* Radio, navigation, Bluetooth, USB ports, etc.
* May include touch screen, buttons or voice controls.
Air conditioning system
* Compressor, condenser, evaporator and fan.
* Cools or heats the air inside the car.
Security system
* Alarm, immobilizer, collision sensors.
* Detects and warns of unauthorized access or accidents.
Sensors and actuators
* Sensors measure various parameters such as speed, temperature and pressure.
* Actuators carry out commands from the ECU, such as turning valves on or off or adjusting dampers.
Electrical wiring and connectors
*Transmits electrical current throughout the vehicle.
* Connections are protected from corrosion and vibration.
Regular maintenance and repair of your vehicle’s electrical system is critical to keeping it running reliably and safely.
