Abstract
Systems and methods for warming batteries are generally disclosed. According to one aspect, a system for warming a battery includes one or more rectifiers each having an input for receiving an input voltage and an output configured to provide an output voltage to a load. The system also includes at least one battery having an input for receiving an input voltage to charge the battery. The battery is coupled to the load and configured to provide an output voltage to the load. The system also includes a controller coupled to the battery and configured to raise the output voltage of the battery above the output voltage of the one or more rectifiers so that current flows from the battery, thereby warming the battery.
