Power Control Unit (PCU)
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

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.
