  • Patent number: 11865936
    Abstract: A direct current (DC) electric vehicle supply equipment (EVSE) that includes a secure enclosure. The secure enclosure encloses a set of one or more contactors to open and close to provide DC charge transfer with one or more electric vehicles; a conductor to electrically connect the contactors with DC input; a current sensor to measure current draw; a voltage sensing circuitry to measure voltage; and one or more circuits that receive current data from the current sensor and voltage data from the voltage sensing circuitry, the one or more circuits to perform one or more safety functions and one or more metering functions using the received current data and voltage data. The DC EVSE may also include, external to the secure enclosure, a controller that is coupled with the circuits to control the opening and closing of the set of contactors.

  • Patent number: 11780345
    Abstract: A plurality of charging equipment share a current capacity. A message is received that indicates a request for allocation of electric current through a first charging equipment of the plurality of charging equipment. Responsive to determining that granting the request would exceed the current capacity, the electric current is dynamically allocated among the plurality of charging equipment such that the first charging equipment is allocated electric current without exceeding the current capacity shared by the plurality of charging equipment.

  • Patent number: 11148551
    Abstract: A first dispenser receives a request to initiate charging service for charging an electric vehicle. The first dispenser determines an amount of power that is available for the charging service for charging the electric vehicle including determining an availability status of multiple power modules that are located in the first dispenser and a second dispenser. The first dispenser determines whether the available amount of power is enough to meet a requested or determined amount of power draw of the electric vehicle. If the available amount of power is not enough to meet the requested or determined amount of power draw of the electric vehicle, and if there is at least one of the power modules that is available, the first dispenser requests allocation of the available power module and charging service commences.
