Patent number: 11973348Abstract: A controller initiates operation of a climate system in advance of a departure time defined by a user such that the climate system operates for a duration defined by the user before the departure time, provided that grid power from a plug is not available to power the operation. The controller also initiates operation of the climate system at a start time selected by the controller such that a temperature within a cabin achieves a target temperature defined by the user in advance of the departure time and the climate system does not operate for a duration defined by the user before the departure time, provided that the grid power is available to power the operation.Type: GrantFiled: January 12, 2021Date of Patent: April 30, 2024Assignee: Ford Global Technologies, LLCInventors: Charles Everett Badger, II, Angel Fernando Porras

Patent number: 11465533Abstract: A vehicle includes an electric machine, a battery, an accelerator pedal, a battery cooling system, and a controller. The electric machine is configured to propel the vehicle. The battery is configured to provide electrical power to the electric machine. The battery cooling system is configured to cool the battery in a plurality of cooling modes. A transition between cooling modes of the battery cooling system corresponds to either an increase or a decrease in battery power being utilized to cool the battery. The controller is programmed to truncate an acceleration request under certain conditions to prevent an increase in battery power output in order to reduce a rate at which the battery temperature increases and to prevent a transition to a cooling mode that requires an increase in battery power output.Type: GrantFiled: December 18, 2019Date of Patent: October 11, 2022Assignee: Ford Global Technologies, LLCInventors: Yanan Zhao, Xiaohong Nina Duan, Jeffrey Allen Doering, Angel Fernando Porras, Jordan Mazaira
