A hybrid electric drive system including a hydraulic power system for a hybrid powered vehicle which includes a transmission, and a combustion engine and an electric motor both mechanically coupled to the transmission to provide engine and/or motor drive power for the vehicle. A plurality of hydraulic circuits communicate with an electrically driven hydraulic pump. The hydraulic pump is configured to provide fluid circulation to the plurality of hydraulic circuits. The hydraulic circuits are each connected to the transmission and other corresponding vehicle components. An electrical power supply is configured to power the electrically driven hydraulic pump, and the electrical power supply is electrically communicating with a rechargeable high voltage (HV) battery system. The electrically driven hydraulic pump communicates with the plurality of hydraulic circuits to provide fluid pressure in the hydraulic circuits.
