  • a charging station configured for connecting multiple electric vehicles (EVs) to a single charging station for receiving and sharing current from a power grid;

    a coordinator system coupled to each said charging station for generating multiple pilot control signals, one for each EV being charged, for communicating information with each of said multiple EVs and specifying maximum charge current available to each of said multiple EVs;

    a gateway device configured for communicating with and controlling said coordinator system;

    said gateway device sends commands to said coordinator system to set said maximum charge current for each EV in response to distributing an amount of charge current available at the charging station toward dividing it up across the number of EVs coupled to the charging station.
