Abstract
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 a direct current (DC) bus 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 DC bus connection to provide DC current from the battery to the DC bus and to provide DC current from the DC bus to the battery, as controlled by the system controller. A centralized management system may also communicate with and control aspects of operation of the respective system controllers of the charging stations.
