1. A method for controlling a vehicle charging and thermal operation comprising:
monitoring at least a charge characteristic of a battery system and a thermal characteristic of the battery system;
predicting a battery system temperature at a future time (t) based at least in part on the monitored characteristics using a predictive physics model;
maintaining the battery system temperature above a minimum temperature threshold and below a maximum temperature threshold by adjusting a charging profile based at least in part on the predicted battery system temperature; and
adjusting the charging profile comprises applying a cost function, the cost function being configured to optimize for at least maximum charging power with minimum heating power and minimum cooling power.
