Abstract
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.
Claims8
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 the maximum amount of electric current supported by the electrical circuit supports less than a complete utilization of the electric vehicle charging stations;
- and
- dynamically allocating electric current to at least two of the electric vehicle charging stations based on at least an amount of electric current presently allocated on 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 electric vehicle charging stations to draw electric current through the electrical circuit for at least some amount of time.
