1. A transport refrigeration system comprising:
a compressor, condenser and evaporator configured to circulate a refrigerant;
a motor configured to drive the compressor;
a battery and power electronics configured to power the motor;
an ambient air temperature sensor configured to monitor ambient air at the battery;
a cooling unit configured to cool the power electronics;
a controller, wherein the controller is configured to:
receive an ambient air temperature at the battery;
compare the ambient air temperature to a temperature threshold; and
based at least in part on the comparing the ambient air temperature to the temperature threshold, modifying an operating parameter of the power electronics, wherein the modifying the operating parameter of the power electronics includes increasing heat generated by the power electronics.
