One or more systems and methods for providing selective isolation between a grid and an electric vehicle (EV) during charging are disclosed. An isolation component may be located between input nodes, and one or more output nodes. The isolation component may be connected to the nodes by switches that select which one or more nodes is used to supply power for charging the EV battery. Other switches, such as relays, may bypass the isolation component when the grid is not connected. Further switches may isolate part of the system from the grid to connect the isolated power source to the EV, and in parallel connect the isolation component to the grid for combined power EV battery charging. The isolation component may comprise electrical energy storage devices with switches in series surrounding each device, where the switches may be operated in a break-before-make transition.
