1. A vehicle, comprising:
a battery;
a battery thermostat configured to preheat the battery and including at least one of a heater or an air conditioning system;
a battery sensor configured to measure at least one of an output voltage or an output current and to output a signal based upon the measurement;
an outside temperature sensor configured to measure an outside air temperature of the vehicle; and
a controller including a processor configured to:
calculate a first state of charge (SOC) of the battery based on the signal output by the battery sensor;
identify a maximum temperature of the battery corresponding to the first SOC and the outside air temperature;
determine a preheating temperature of the battery based on a predetermined reference temperature corresponding to a start of charging the battery, the maximum temperature, and a predetermined limit temperature of the battery in response to a comparison of the maximum temperature and the predetermined limit temperature; and
control the battery thermostat based on the determined preheating temperature.
