Patent number: 11958380Abstract: Dynamic allocation of power modules for charging electric vehicles is described herein. The charging system includes multiple dispensers that each include one or more power modules that can supply power to any one of the dispensers at a time. A dispenser includes a first power bus that is switchably connected to one or more local power modules and switchably connected to one or more power modules located remotely in another dispenser. The one or more local power modules are switchably connected to a second power bus in the other dispenser.

Patent number: 11780345Abstract: 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.Type: GrantFiled: February 9, 2021Date of Patent: October 10, 2023Assignee: CHARGEPOINT, INC.Inventors: David Baxter, Carl F.

Patent number: 11148551Abstract: 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.Type: GrantFiled: August 17, 2020Date of Patent: October 19, 2021Assignee: CHARGEPOINT, INC.Inventors: Richard J.
