Electrical Circuit Sharing for Electric Vehicle Charging Stations

摘要

Electric vehicle charging stations are coupled with a circuit sharing controller. Multiple electric vehicle charging stations are wired on the same electrical circuit. The circuit sharing controller implements a circuit sharing process that dynamically allocates electric current to charging stations on the same electrical circuit such that the capacity of the electrical circuit is not exceeded while permitting each of those charging stations to draw electric current through that electrical circuit for at least some amount of time.

主权项

1. A method for a shared electrical circuit infrastructure for charging electric vehicles, comprising:
determining a maximum amount of electric current supported by an electrical circuit that is shared among a plurality of electric vehicle charging stations, wherein each of the electric vehicle charging stations are coupled with a circuit sharing controller; and dynamically allocating electric current to at least some of the electric vehicle charging stations based on at least an amount of electric current presently allocated for the electrical circuit such that the maximum amount of electric current supported by the electrical circuit is prevented from being exceeded while permitting each of the least some of the electric vehicle charging stations to draw electric current through the electrical circuit for at least some amount of time.
