Abstract

The present disclosure relates to an electric vehicle opportunistic charging system and method. A vehicle includes an electric machine arranged to exchange electrical power with a traction battery. The vehicle also includes a thermal regulation system for affecting the temperature of the battery and a controller configured to schedule charging of the battery. In response to the temperature of the traction battery exceeding a threshold, the controller issues a command to operate the thermal regulation system prior to the scheduled battery charge to achieve a predetermined battery temperature when the battery charge begins.

Description

technical field [0001] The present application generally relates to charging a traction battery of a hybrid electric vehicle using an engine. Background technique [0002] A hybrid electric vehicle may include an internal combustion engine (ICE), at least one electric machine, which may be configured as an electric motor or generator, and a traction battery. The traction battery provides electrical power to the electric motors for propulsion and to supply certain accessory loads. Vehicles utilizing high voltage traction batteries may be referred to as electrified vehicles. Traction batteries have a state of charge (SOC) that indicates how much charge is held in the battery. To increase SOC, a hybrid electric vehicle can employ a number of methods including: using the vehicle's momentum to turn an electric generator to charge the traction battery, operating the ICE to turn an electric machine configured as a generator, and turning the The traction battery is electrically c...
