Abstract
An electronic circuit configured to operate in any of a plurality of charging and heating modes for two batteries, a primary battery and a secondary battery. The electronic circuit includes a plurality of switch and diode pairs in a stacked configuration. The stacks of switch and diode pairs are connected to an inductor, to a plurality of mode control switches, and the two batteries. The mode control switches are used to set the modes, which include a charging mode, a self-heating, a power exchange-heating mode, and a direct power transfer mode.
