Abstract
A heating system and a method for heating a battery module are provided. The method includes generating a temperature signal indicative of a temperature level of at least one of a first battery cell group and a second battery cell group. If a temperature level is less than the threshold temperature level, then the method further includes generating first and second control signals to induce first and second switches, respectively, to each have a first operational position to at least partially discharge the first and second battery cell groups, respectively, through first and second resistors, respectively, to generate heat energy in the first and second resistors.
