The power supply device performs one-side charge control for controlling the system main relay, the charging relay, the series connection relay, the parallel connection relay, and the first and second neutral point relays so that only the first power storage unit is charged using the external DC power until the voltage of the first power storage unit becomes equal to or higher than the voltage of the second power storage unit before the first and second neutral point relays are turned on and the power storage device is charged using the external DC power.

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.
