US Patent 11973348 Grid power dependent preconditioning of vehicle

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.
