Patent number: 12071041Abstract: A charging system includes a charging controller and an estimated completion time deriver. The charging controller adjusts a temperature of an on-board battery with a heater so that the temperature of the battery is kept equal to or higher than a predetermined temperature. The battery is chargeable with electric power supplied from a power supply outside a vehicle. The charging controller charges the battery with charging power excluding temperature adjustment power consumed by the heater from permitted suppliable power supplied from the power supply to the vehicle. The estimated completion time deriver derives an estimated completion time based on an estimated value of the permitted suppliable power in a future and an estimated value of the temperature adjustment power that is derived based on an estimated value of an outside air temperature in the future. The estimated completion time is a time when charging is predicted to complete.Type: GrantFiled: October 1, 2020Date of Patent: August 27, 2024Assignee: SUBARU CORPORATIONInventor: Yosuke Ohtomo
