Abstract: A reefer truck power unit employs a plurality of power sources including roof mounted solar panels, momentum generation, shore power and high capacity storage batteries. The refrigeration system is configured for refrigerating a payload area of the vehicle utilizing power from the power sources, and employs a voltage converter for augmenting the power from the propulsion vehicle source for use with a native vehicle charging//starting system, and a transport load transformer for converting power from the power sources to 3 phase power for powering the refrigeration system. A bank of batteries stores power from the sources for subsequent dispersal to the refrigeration unit.

Abstract: A vehicle energy management system for gathering, storing the energy, and distributing the stored energy supports various subsystems on the vehicle such as driver comfort systems, payload refrigeration, liftgate mechanisms, and roof de-icing, for example. The system harvests energy from various sources available to the vehicle, such as solar panels, regenerative braking and shock absorbers. The harvested energy is gathered for battery storage. Management logic allocates the stored electricity to various vehicle loads defined by the subsystems, based on factors such as time of day, ambient temperature, and weather conditions, which are used to predict the electrical demand called for by the loads.

Abstract: In a satellite power distribution system such as for use in a communications satellite, a first load powering power distribution bus receives power from a first solar panel. A second load powering power distribution bus receives power from a second solar panel. One of the buses is connected to a battery system to provide power to loads during night periods. The loads connected to the other bus are not powered during the night periods.
