Abstract

See full text

A multiple EVSE installation employs a power sharing system for EVSE pairs which share a common circuit breaker. When only one EVSE is connected to an electric vehicle for charging, the connected EVSE is allowed to charge at full capacity. When a second EV connects to the second EVSE of the pair, while the first EVSE is charging, a controller senses the latter event and issues commands to both EVSE units to limit their current so that the rated circuit breaker capacity is not exceeded. The controller continuously monitors the charging of each of the EVSE units and sends commands to adjust the supply of current to each EVSE accordingly.
