Abstract

A heating system includes first and second input ends, first and second battery modules, first switch and second switches, and a control unit. The first switch is connected between first terminals of the first and second battery modules. Second terminals of the first and second battery modules are connected to each other. The second switch is connected between the first input end and the first terminal of the second battery module. The second input end is connected to the first terminal of the first battery module. The first terminals of the first and second battery modules have a same polarity, and the second terminals of the first and second battery modules have a same polarity. The control unit is connected to the first and second switches, and configured to control the first and second switches to be turned on or off.
