  • Patent number: 10654341
    Abstract: A system including mode, engine, and battery modules, where the mode module determines whether to operate in an engine mode or a battery mode based on parameters. The engine module, while operating in the engine mode, runs a compressor at a first speed based on a temperature within a temperature controlled container of a vehicle and permits passage of refrigerant through eutectic plates independent of the temperature. A battery, while in the engine mode, is charged based on power received from an electrical source. The battery module, while operating in the battery mode and based on the temperature, runs the compressor at a second speed and prevents passage of the refrigerant through the eutectic plates. While in the battery mode, the battery is not being charged based on power from a shore power source and the electrical source from which power is received during the engine mode.
