Zusammenfassung:	A transport refrigeration unit controllably cools a container, and includes a compressor (58) constructed and arranged compress a refrigerant and a compressor motor (60) configured to drive the compressor (58). A battery (52) of the unit is configured to at least in-part provide electric power to the compressor motor (60). A power management system of the unit includes a computer-based controller configured to generate diagnostic data from data signals received from a battery temperature sensor (122), a battery current sensor (124), and a compressor motor current sensor (126).
