EVSE DOUBLER ADD-ON UNIT
First Claim
1. An adapter to double available charging handles for an electric vehicle charging station, comprising:
- an adapter controller configured to electrically connect to a charging port of an electric vehicle charging station, the adapter controller being further configured to electrically connect to two electric vehicle charging handles configured to charge two electric vehicles;
a charge sharing control circuit in the adapter controller, coupled to two electric vehicle control pilot connectors in two electric vehicle charging handles and coupled to a charging station control pilot socket in the charging port of the electric vehicle charging station, the charge sharing control circuit being configured to determine a modified available charging rate to be offered to each of the two electric vehicles, for sharing power by simultaneously charging the two electric vehicles, based on connection states of the two electric vehicles to the electric vehicle charging handles and based on an available charging rate offered by the charging station; and
the adapter controller being configured to transmit to each of the two electric vehicles, a charging rate offer representing the determined modified available charging rate.

Abstract
An add-on adapter 110 enables a single charging port 102 of an electric vehicle charging station 100 to simultaneously charge two electric vehicles. An adapter controller 120 determines the available charging rate offered by the charging station. Electric vehicle charging handles 150A, 150B are determined to be connected to the electric vehicles. A charge sharing control circuit 300 in the adapter controller, determines modified available charging rates to be offered for simultaneously charging the electric vehicles. The modified available charging rates are based on the connection states of the electric vehicles and the available charging rate offered by the charging station. The adapter controller controls two contactors 130A, 130B to switchably connect a charging station power socket to the electric vehicle charging handles, to provide shared power at the determined modified available charging rate to the electric vehicles, for simultaneous charging.
