Single electric vehicle charger for electrically connecting to multiple electric vehicles simultaneously while automatically charging the multiple electric vehicles sequentially
First Claim
1. A single electric vehicle charger for electrically connecting to multiple electric vehicles simultaneously while automatically charging the multiple electric vehicles sequentially in order to control electric consumption of the single electric vehicle charger to avoid exceeding electric service limitations feeding the single electric vehicle charger, comprising:
- a) an AC to DC rectifier;
b) at least one ground fault circuit interrupter; and
c) at least two physical electrical disconnects;
wherein said AC to DC rectifier is for electrically connecting to an AC power source;
wherein said AC to DC rectifier is for converting AC power to DC power so as to allow DC batteries of the multiple electric vehicles to be charged from the AC power source;
wherein said at least one ground fault circuit interrupter is in electrical communication with said AC to DC rectifier;
wherein said at least one ground fault circuit interrupter is for disconnecting whenever current becomes unbalanced between an energized conductor and a return neutral conductor;
wherein said at least two physical electrical disconnects are in electrical communication with said at least one ground fault circuit interrupter; and
wherein said at least two physical electrical disconnects are for isolating the multiple electric vehicles that are electrically connected but are not being charged, with only one physical electrical disconnect being closed at any given instant so as to allow for the electrically connecting to the multiple electric vehicles simultaneously while automatically charging the multiple electric vehicles sequentially in order to control the electric consumption of the single electric vehicle charger to avoid exceeding, the electric service limitations feeding said single electric vehicle charger.

Abstract
A single electric vehicle charger for electrically connecting to multiple electric vehicles simultaneously while automatically charging the multiple electric vehicles sequentially. The charger includes an AC to DC rectifier, at least one ground fault circuit interrupter, and at least two physical electrical disconnects. The AC to DC rectifier electrically connects to an AC power source and allows DC batteries of the multiple electric vehicles to be charged from the AC power source. The at least one ground fault circuit interrupter is in electrical communication with the AC to DC rectifier and disconnects whenever current becomes unbalanced between an energized conductor and a return neutral conductor. The at least two physical electrical disconnects are in electrical communication with the at least one ground fault circuit interrupter and isolate the multiple electric vehicles that are electrically connected but are not being charged, with only one physical electrical disconnect being closed at any given instant.
