1. An electrified vehicle, comprising:
a battery;
a thermal management system configured to thermally condition the battery at one of a plurality of thermal conditioning levels, wherein each of the thermal conditioning levels corresponds to a respective one of a plurality of battery temperature thresholds; and
a controller,
wherein the controller is configured to determine which of the plurality of battery temperature thresholds is met or exceeded based on a temperature of the battery and to command the thermal management system to thermally condition the battery at corresponding one of the plurality of thermal conditioning levels,
wherein, when a state of health of the battery is outside a predefined range, the controller is configured to adjust each of the plurality of battery temperature thresholds.
