  • Power management system for integrated transport refrigeration unit
    Patent number: 7874169
    Abstract: A power management system (36) supplies power to a refrigeration unit (20) of a vehicle (22). When a vehicle engine (40) is running, the refrigeration unit receives power from a DC power source (38). When the vehicle engine is not operating, power is supplied through an AC source (46). A converter (42) within the power management system converts the AC power to Dc power and sends the power to the refrigeration unit. If the user attempts to start the vehicle engine when the refrigeration unit is receiving power through the converter, there is conflict in power supply. The power management system will activate an alarm (48) to alert the user to an attempt to power the refrigeration unit with two different power systems.
