Managing electric current allocation of electric vehicle charging stations
First Claim
Patent Images
1. A method, comprising:
- receiving a first message that indicates a request for an allocation of electric current at a first one of a plurality of electric vehicle charging stations that are connected to a same main electrical circuit breaker, and wherein at least a second one of the plurality of electric vehicle charging stations is presently allocated electric current;
determining that granting the request would exceed a maximum amount of electric current supported by the main electrical circuit breaker; and
responsive to that determination, adjusting the electric current allocation of at least the second one of the plurality of electric vehicle charging stations such that the request for allocation can be granted; and
granting the request and allocating electric current to the first electric vehicle charging station.

Abstract
A message is received that indicates a request for an allocation of electric current at a first electric vehicle charging station that is connected to a same main electrical circuit breaker as a second electric vehicle charging station that is presently allocated electric current. Responsive to determining that granting the request would exceed a maximum amount of electric current supported by the main electrical circuit breaker, the electric current allocation of at least the second electric vehicle charging station is adjusted such that the request for allocation can be granted and the request is granted and electric current is allocated to the first electric vehicle charging station.

7. A method of sharing power between at least a first electric vehicle charging station and a second electric vehicle charging station so as to not exceed a capacity of a main electrical circuit breaker connected to the first electric vehicle charging station and the second electric vehicle charging station that would otherwise occur if the first electric vehicle charging station and the second electric vehicle charging station were each supplying current at their maximum ratings, comprising:
-
receiving, at a first electric vehicle charging station, a first message that indicates a first amount of current that is allowed to be drawn through the first electric vehicle charging station; responsive to receiving the first message, the first electric vehicle charging station limiting an amount of current to be drawn through the first electric vehicle charging station in accordance with the first message; receiving, at the first electric vehicle charging station, a second message that indicates a second amount of current that is allowed to be drawn through the first electric vehicle charging station, wherein the second amount of current is less than the first amount of current and is a value that allows the second electric vehicle charging station to draw at least some electrical current while not exceeding the capacity of the main electrical circuit breaker; and responsive to receiving the second message, the first electric vehicle charging station limiting the amount of current to be drawn through the first electric vehicle charging station in accordance with the second message. - View Dependent Claims (8, 9, 10, 11)

12. An apparatus, comprising:
-
a processor; and a non-transitory machine-readable storage media that contains instructions, which when executed by the processor, cause said processor to perform the following operations; receiving a first message that indicates a request for an allocation of electric current at a first one of a plurality of electric vehicle charging stations that are connected to a same main electrical circuit breaker, and wherein at least a second one of the plurality of electric vehicle charging stations is presently allocated electric current; determining that granting the request would exceed a maximum amount of electric current supported by the main electrical circuit breaker; and responsive to that determination, adjusting the electric current allocation of at least the second one of the plurality of electric vehicle charging stations such that the request for allocation can be granted; and granting the request and allocating electric current to the first electric vehicle charging station. - View Dependent Claims (13, 14, 15, 16, 17)
