Abstract
A battery-heating system and method using a motor-driving system is provided. The battery-heating system includes an inverter having legs respectively including a pair of switching elements connected in series between the ends of a battery and corresponding to a plurality of phases. A motor of the system includes coils each having one end connected to a connection end between a pair of switching elements of the legs, other ends of the plurality of coils being connected together. A controller determines one of the plurality of phases as a reference phase, and alternately controls the on-off states of the switching elements so that the on-off state of the switching element included in the leg corresponding to the reference phase and the switching element included in the other leg are mutually complementary, thereby generating AC current to be injected into the battery.
