Abstract
A system for increasing a temperature of a battery includes an inverter including a plurality of legs each including one pair of switching devices connected in series to each other between opposite ends of the battery and corresponding to a plurality of phases, respectively, a motor including a plurality of coils corresponding to the plurality of phases, respectively, where one end of each of the plurality of coils is connected to a connection node between one pair of switching devices included in a corresponding leg and other ends of the coils are connected to each other, and a controller configured to select two phases of the plurality of phases, and to alternately control an on/off state of switching devices included in two legs in the inverter, corresponding to the two selected phases, at a preset switching frequency to generate alternating current (AC) supplied to the battery.
