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.
