The Power Control Unit is required:
- For charging the auxiliary battery.
- For supplying the vehicle electrical system from the auxiliary battery.
The Power Control Unit (PCU) contains a DC/DC converter with a power of 500 W.
The preconditions for the direction of the energy management are calculated from the use of the vehicle. The auxiliary battery is charged by the PCU when the engine is running. During the phases in which the combustion engine is not running, e.g. automatic engine start/stop function, the PCU supplies energy from the auxiliary battery to the vehicle electrical system.
