Parts of a Car Charging System


The battery is a reservoir to store energy. It is kept on standby for functions like starting the car and providing power when the power supply is low.

If you were to rely solely on battery power, though, your car wouldn’t run for long without being charged.


It’s why we have the alternator. The alternator is the component that produces that power. As you’re driving along, the alternator creates energy to power the system while the excess energy is used to recharge the battery.

Voltage Regulator

The voltage regulator ensures that the maximum amount of voltage in the circuit is kept constant. It can, therefore, prod the alternator to up production or prompt it to reduce energy production.

The idea is to create a steady stream of current that can power the vehicle consistently. The excess power doesn’t go to waste because it charges the battery.
