In order to ensure reliable power for charging electric vehicles is available at each charging station at a charging site having multiple charging stations, the systems and methods disclosed herein provide for charge transfers between batteries of such charging stations. A plurality of charging stations at a charging site are connected via local alternating current (AC) circuit in order to transfer energy between the charging stations, such as to balance the energy stored at the respective batteries of the charging stations. Each charging station includes a system controller controlling operation of the charging station and a bidirectional inverter to convert AC input power from a power grid or the local AC circuit to direct current (DC) power for storage in a battery of the charging station and to convert DC power from the battery to AC output power to the local AC circuit, as controlled by the system controller.
