What primarily provides power to a car?
1 Answers
The car's power supply system mainly consists of the battery, generator, and voltage regulator. The generator is responsible for charging the battery, keeping it fully charged over time. Both the battery and generator supply power to all the vehicle's electrical components. Below is relevant information: 1. Battery: It can be divided into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses lead-calcium alloy for the grid frame, the amount of water decomposed during charging is minimal, and water evaporation is low. 2. Generator: It is the main power source of the car. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally (above idle speed), while also charging the battery. 3. Voltage regulator: Since the generator is driven by the car's engine, and the engine speed is not constant, this can cause instability in the generator's output voltage. Therefore, an electronic device is necessary to control the generator.
