1. A climate control system for a hybrid heavy duty vehicle having an engine-on condition while driving and an engine-off condition while parked, comprising:

  • an electrically powered compressor;

    an energy storage device connected in electrical communication with the electrically powered compressor for supplying power thereto;

    at least one sensor capable of outputting signals indicative of an engine-on condition or an engine-off condition; and

    a controlling component operable to receive the signals of the at least one sensor, and based on said signals and energy storage level data from the energy storage device, operate to selectively control the power supplied to the electrically powered compressor so as to provide a first compressor output level during a vehicle engine-on condition and a second, lower, compressor output level during a vehicle engine-off condition, wherein the second compressor output level is selected so as to allow the compressor to operate at a lower output as compared to the first compressor output level for a predetermined period of time.
