1. A vehicle comprising:
a traction battery having a plurality of cells configured to store electric energy; and
a controller programmed to, after start of the vehicle following a parking event having a duration that exceeds a duration threshold, reduce a maximum output power of the traction battery based on a sensed temperature of the traction battery when the parking event begins, a sensed ambient temperature when the parking event begins, a sensed ambient temperature when the parking event ends, and the duration.
