A photovoltaic extended-range vehicle composite power supply control system and method

Abstract

The invention provides a photovoltaic augmentation type vehicle-mounted composite power supply control system and method. The system comprises a main control unit, a composite power supply system, a solar panel, a state monitoring unit, a composite power supply topology structure, an energy distribution unit and a driving system. The solar panel used to provide energy to the composite power systemand drive system, and can realize a variety of separate energy supply modes through the composite power supply topology; the composite power system for supplying power to the drive system; the statusmonitoring unit monitors the status information of the solar panel and the composite power system and transmits the status information to the main control unit. The main control unit allocates energyto the drive system by receiving state information and controlling the composite power supply topology and the energy distribution unit. As that scheme provide by the invention can fully utilize thesolar energy through the super capacitor, the performance of the composite power supply is taken into account, and the method has the advantages of simple structure, easy realization and low cost.
