Abstract
An electrified vehicle includes a traction battery and a battery thermal control system. A controller is configured to receive an initial regenerative braking capability and operation the battery thermal control system to precondition the traction battery during a charge event to a temperature that corresponds to the initial regenerative braking capability such that, during a subsequent drive cycle, the regenerative braking capability is at least equal to the initial regenerative braking capability for at least a predetermined duration into the subsequent drive cycle.
Claims20
An electrified vehicle comprising:
- a traction battery;
- a battery thermal system configured to heat and cool the traction battery;
- a user interface configured to receive a user entry defining an initial regenerative braking capability for a next drive cycle;
- and
- a controller programmed to operate a braking system to incorporate regenerative braking up to a regenerative power capability that is based on operating conditions of the traction battery during a drive cycle, and responsive to the electrified vehicle being connected to an external charger, operate the battery thermal system prior to a start of the next drive cycle to precondition the traction battery to a predetermined temperature corresponding to the initial regenerative braking capability such that the regenerative power capability is at least equal to the initial regenerative braking capability for a predetermined duration into the next drive cycle.
A method comprising:
- receiving, by a controller, an initial regenerative braking capability of a vehicle for a subsequent drive cycle;
- and
- responsive to an external charger being coupled to vehicle, operating, by the controller, a thermal control system for a traction battery using energy from the external charger to precondition the traction battery to a predetermined temperature corresponding to the initial regenerative braking capability prior to a subsequent drive cycle such that a regenerative braking capability of the vehicle is at least equal to the initial regenerative braking capability for a predetermined duration into the subsequent drive cycle.
A battery thermal control system for a vehicle comprising;
- a heating element configured to provide heat to a traction battery;
- a cooling element configured to cool a traction battery;
- and
- a controller programmed to receive an initial regenerative braking capability for a subsequent drive cycle entered by a user of the vehicle and, responsive to the traction battery being charged from an external charger, operate the heating element and the cooling element to precondition the traction battery to a predetermined temperature corresponding to the initial regenerative braking capability prior to a start of the subsequent drive cycle.
