Abstract
An electrified vehicle includes a traction battery, an engine, and a controller. The controller is configured to generate a request for the engine in response to an input passing a threshold and to adjust the threshold when a state of health (SOH) of the traction battery is at a chance of violating a target, such as a warranty target. The request for the engine may be an engine pull up (EPU) request for starting the engine with the threshold being an EPU threshold in which case the controller lowers the EPU threshold when the battery SOH is at a chance of violating the target. The request for the engine may be an engine pull down (EPD) request for stopping the engine with the threshold being an EPD threshold in which case the controller lowers the EPD threshold when the battery SOH is at a chance of violating the target.
