Transportation refrigeration unit with cold climate battery heating

Abstract

A transportation refrigeration unit (26) comprising: a compressor (58) configured to compress a refrigerant; a compressor motor (60) configured to drive the compressor (58), the compressor motor (60) being powered by an energy storage device (152); an evaporator heat exchanger (76) operatively coupled to the compressor (58); a controller (82) to control operation of the transportation refrigeration unit (26); an ambient air temperature sensor (83) in electronic communication with the controller (82), the ambient air temperature sensor (83) detects ambient air temperature outside of the transportation refrigeration unit (26), wherein the controller (82) adjusts operation of a temperature control system (153) for the energy storage device (152) in response to the ambient air temperature, the temperature control system (153) adjusts a temperature of the energy storage device (26).
