In BMW motor vehicles, the battery voltage for passenger and light commercial vehicles is 12 volts. In commercial vehicles such as buses, trucks, and lorries, the electric voltage is 24 volts. In motor vehicles, electrical energy is chemically stored in batteries. Additionally, the entire lighting system of a vehicle is connected to its own battery system unless an external system is installed, drawing power from the battery.

The electrical system in cars is a system that provides power and signal transmission between the vehicle's electrical components. The importance of the electrical system can be explained as follows:

Operation of Electric Systems: There are many electric systems in cars, such as lighting, horn, turn signals, air conditioning, radio, electric windows, and central locking. The electrical system ensures that these systems operate correctly. Electrical energy is transmitted from the battery or alternator to these components through the electrical system, allowing the electric systems in the vehicle to be used effectively.

Power Transmission: The electrical system is a transmission line that delivers the power needs of the vehicle to the electric components. The electrical energy required for the engine to operate is produced by the alternator and reaches the electrical power needed by the engine through the electrical system. This way, the power needs of all electric components in the vehicle are met.

Fault Detection and Repair: The electrical system is important for detecting and repairing electrical faults in the vehicle. If an electric system or component fails, the circuits on the electrical system can be checked to identify the source of the problem. This allows electrical faults to be resolved quickly, and the vehicle's electric systems can be restored to proper working order.

Safety: The correct and robust operation of the electrical system is important for driving safety. Failures or short circuits in the electrical system can create dangerous situations. For example, incorrect connections or insulation failures can lead to electrical fires. Therefore, properly installing the electrical system, maintaining it, and quickly resolving faults is important to enhance driving safety.

The electrical system in cars ensures the efficient operation of the vehicle's electric components and plays a critical role in driving safety.
