This paper presents a switching bi-directional buck-boost converter (SBBBC) for vehicles to grid (V2G) system. The topology can provide an energy bi-directional flow path for energy exchange between the Li-battery/supercapacitor (SC) hybrid energy storage system (HESS) of the electric vehicle and the grid. This topology not only has buck-boost capability but also has the function of energy management. A Fuzzy Logic Controller (FLC) is utilized for energy management based on the predicted future state of the vehicle, in order to improve fuel consumption, emission, and performance. Then, the energy management system is modified to increase the state of charge (SOC) of the power train battery. The control strategy is given according to the state of charge (SOC) of the energy storage system to ensure that the output voltage and current are stable. And the Li battery is charged in constant current (CC) and constant voltage (CV) mode. In addition to a soft switched DC-DC conversion, the circuit also facilitates an additional output which makes the system capable of supporting multiple applications. The circuit under discussion uses fuzzy logic for the closed loop operation which has better overall performance compared to other conventional converters. Finally, the electrical feasibility of the topology, the suitability of the design controller and control strategy are verified by simulation and experiment.
