Pierburg A/C Compressor (eCC) for Electric Vehicles

The new unit is of compact design so that it can fit in the usual installation spaces and serves the regular voltage levels HV2 and HV3. The three modules - mechanical compressor unit, electric motor and power electronics - are modularly integrated.

​During development, particular emphasis was placed on low weight and high operating efficiency. This ensures economical power management with the limited electrical energy available from the high-voltage storage unit in the vehicle.

The well thought-out design of the machine allows not only classical air conditioning operation at warm outside temperatures but also heat pump operation at low ones. By using a heat pump to heat the driver's cab, the energy flow from the high-voltage storage unit can be reduced as required, thus increasing the vehicle's travel range.

​A further development focus was the low noise of the compressor, since its sound and vibrations are perceived as disturbing by the driver and occupants.
