Abstract
A power management method used for power distribution in a transportation refrigeration unit. The power management method includes calculating engine power according to engine operating parameters; calculating power generator real-time input power according to power generator excitation current; calculating available power based on the power generator real-time input power and the engine power; and managing power distributed to a compressor based on the available power. The present invention further relates to a power management system. The power management method and system have the advantages of simplicity, reliability, stable operation and the like, the power generator real-time input power can be calculated according to the power generator excitation current, thus more power can be provided to the compressor on the premise that the power supply to power generator loads is guaranteed, and the operating efficiency of the transportation refrigeration unit is improved.
