Electric Vehicle Battery Charging Station based on Bipolar dc Power Grid with Grid-to-Vehicle, Vehicle-to-Grid and Vehicle-to-Vehicle Capabilities

An electric vehicle (EV) battery charging station (EV-BCS) based on a bipolar dc power grid is presented in this paper, which capable of delivering to the (vehicle-to-grid – V2G mode), and directly exchange between different EVs connected EV-BCS (vehicle-to-vehicle V2V besides traditional operation (grid-to-vehicle G2V mode). The three-level bidirectional buck-boost dc-dc converters has modular structure. Simulation results are with aim validating aforementioned modes, being considered two for simplicity reasons, since it enough validate proposed modes. comprise both balanced unbalanced terms from viewpoint, purpose considering real scenario operation, where consumption or injection side always guaranteed.
