1. A method for operating a battery system of a motor vehicle, the battery system including a battery, a system controller, and a thermal system, the method comprising:
receiving, via the system controller, a recharge signal indicating a request to schedule a recharge event for the battery of the battery system at a selected battery charging station;
determining, via the system controller responsive to receipt of the recharge signal, a target preconditioning temperature devised to optimize the recharge event of the battery;
determining a present state of voltage (SOV) or state of charge (SOC) for the battery at a vehicle location of the motor vehicle;
estimating a predicted SOV or SOC for the battery upon arrival of the motor vehicle at a charging station location, distinct from the vehicle location, of the battery charging station, the estimating the predicted SOV or SOC including forecasting a predicted SOV or SOC battery expenditure to drive the motor vehicle from the vehicle location to the charging station location;
estimating a predicted battery preconditioning time to thermally precondition the battery to the target preconditioning temperature using the predicted SOV or SOC; and
transmitting, via the system controller to the thermal system, a preconditioning signal to precondition the battery based on the present SOV or SOC, the target preconditioning temperature, and the predicted battery preconditioning time.
