An electric or hybrid electric vehicle has a climate control system using a heat pump having a condenser heat exchanger that exchanges heat between refrigerant and working fluid within a hot fluid chamber, and an evaporator heat exchanger that exchanges heat between refrigerant and working fluid within a cold fluid chamber. An insulated fluid reservoir may selectively be placed in fluid communication with the cold fluid chamber, and has a Positive Temperature Coefficient (PTC) heater that may be powered by a drivetrain battery unit or by a shore power source. The hot fluid chamber provides heat to at least one cabin heat exchanger and to at least one ambient air heat exchanger. The cold fluid chamber is connected to at least one vehicle interior cooling module and to a liquid cooled heat sink that may cool an electric motor and power electronics of the vehicle.
