Energy management and control of a solar electric vehicle

This paper deals a detailed study, control and energy management of a solar vehicle Multisource Power Supply. A PVG is used as the principal energy source and the batteries are used as secondary/storage source. The use of this last source can reduce strongly the power stress imposed on the primary source. The power sources (PVG- battery) are connected to the DC bus by two DC / DC converters to establish the power transmission to the traction part. The main source (PVG) is connected to a Boost converter which controlled by an MPPT strategy. Finally an energy management strategy based on satisfying the load power requirement is used, for this reason a DC-DC buck-boost converter to control batteries bank is used. The modeling of the system allowed to test the control strategy for this vehicle with an NEDC urban cycle. Simulation results showing significant efficiency achievements.
