Abstract: In order to provide power for non-charging loads located at charging sites, the systems and methods disclosed herein provide for controlling electric vehicle charging stations to provide alternating current (AC) power to the non-charging loads from power stored in their batteries. One or more charging stations are configured to charge their batteries from an AC power source that also powers a non-charging load at the charging site. Each charging station includes a battery, a bidirectional inverter, and a system controller configured to determine occurrence of a triggering condition associated with availability of the AC power source and to control the bidirectional inverter to convert a direct current (DC) power from the battery into an AC output current to provide to the non-charging load via a local AC circuit at the charging site. The non-charging load may thus be powered without drawing power from the AC power source.

Abstract: An integrated battery cooling module including a battery stack having a top end, a front end, a bottom end separated from the top end by a height of the front end, a back end separated from the front end by a length of the top end. The integrated battery cooling module also includes a frame at least partially enclosing the battery stack on the front end and the back end, the frame compressing the battery stack between the front end and the back end. Further, the integrated battery cooling module includes a cooling plate bonded to and structurally reinforcing the frame and in physical contact with one of the top end and the bottom end of the battery stack.

Abstract: A directed cooling system including a pack housing defining an enclosed volume. Additionally, the directed cooling system includes a first battery module disposed within the enclosed volume and a second battery module disposed within the enclosed volume adjacent the first battery module. The directed cooling system further includes an air cycle system operating in a first mode and a second mode. In the first mode, the air cycle system passes an airflow into the enclosed volume, over the first battery module in a first direction, over the second battery module in the first direction, and out of the enclosed volume. In the second mode, the air cycle system passes the airflow into the enclosed volume, over the second battery module in a second direction, opposite the first direction, over the first battery module in the second direction, and out of the enclosed volume.

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.

Abstract: In order to ensure continued charging of electric vehicles when a charging station is not currently received an input power from an external power source, the systems and methods disclosed herein provide for operation of the charging station in a resilient operating mode in which an operating current is derived from a charge previously stored in a battery of the charging station. The operating current is produced by a resilient power subsystem within the charging station using the stored charge and is provided by the resilient power subsystem to one or more system components within the charging station in order to enable continued operation of the charging station, including enabling continuing vehicle charging during a time interval in which the charging station is not receiving input power from an external power source.
