1. Generator.
2. Rechargeable battery.
3. DC-DC converter (vehicles with i-stop system).
Note: The location of the starting system components is shown using a gasoline engine as an example. The arrangement of components for a diesel engine is completely similar.
The charging system uses a generator without a voltage regulator (with integrated power transistor). The generator has a stator with two delta connections. The generator is driven by the engine through a drive belt, generating the electricity needed to power all on-board consumers of the car.
The battery is used to store the electricity generated by the generator, as well as to provide power to consumers when the generator is not working. The battery is located on the left side of the vehicle's engine compartment.
Vehicles equipped with the i-stop system additionally have a DC-DC converter in the charging system, which is necessary to temporarily reduce the voltage in the on-board network to start the starter. The DC-DC converter is installed at the front of the vehicle on the left.
