Beschreibung
Zusammenfassung:	A vehicle having a mixed chemistry battery having first and second battery modules, a temperature sensor, a battery heating system configured to selectively heat the first battery module and/or the second battery module, and a controller. The controller configured to monitor the temperature of the first battery module, activate the heating system based on a determination that the temperature is below a minimum threshold value, monitor a first state-of-charge (SoC) of the first battery module and the second battery module, calculate a minimum set-point temperature for the first battery module based on the first SoC, the second SoC, and a maximum current load of the first battery module, and instruct the battery heating system to provide a portion of a total available heating power of the battery heating system to the first battery module and a remainder of the total available heating power to the second battery module.
