Abstract
A heating circuit for an energy storage device having a core with an electrolyte, the energy storage device having inputs, characteristics of a capacitance across the electrolyte and the core, and internal surface capacitance between the inputs which can store electric field energy between internal electrodes of the energy storage device that are coupled to the inputs, the battery heating circuit including: a controller configured to switch between a positive input voltage and a negative input voltage provided to one of the inputs at a frequency sufficient to effectively short the internal surface capacitance of the energy storage device to generate heat and raise a temperature of the electrolyte, the controller being further configured to discontinue the switching when the temperature of the electrolyte and/or the energy storage device is above a predetermined temperature that is considered sufficient to increase a charging efficiency of the energy storage device.
