Claim 0:
1. A transportation refrigeration unit (TRU) and power system comprising:
a compressor configured to compress a refrigerant, the compressor having compressor motor configured to drive the compressor;
an evaporator heat exchanger operatively coupled to the compressor;
an evaporator fan configured to provide return airflow from a return air intake and flow the return airflow over the evaporator heat exchanger;
a return air temperature (RAT) sensor disposed in the return airflow and configured to measure the temperature of the return airflow;
a TRU controller operably connected to the RAT sensor and configured to execute a process to determine an alternating current (AC) power requirement for the TRU based on at least the RAT;
a generator power converter, the generator power converter configured to receive a generator three phase AC power provided by an AC generator coupled to an axle or wheel hub and transmit a second DC power;
an energy storage system configured to receive the second DC power, provide a first three phase AC power, and receive a second three phase AC power; and
a power management system configured to receive the first three phase AC power and direct at least a portion of the three phase AC power to the TRU based at least in part on the AC power requirement, the power management system generating a TRU DC power from the first three phase AC power and directing the TRU DC power to the TRU system.
