Zusammenfassung:A system of increasing a temperature of a battery for a vehicle includes: an on-board charger having a capacitor and a bidirectional direct current (DC) converter having first input/output terminals connected to the capacitor and second input/output terminals connected to a battery and configured to perform a bidirectional power transfer between the first input/output terminals and the second input/output terminals; and a controller to drive, when temperature rising of the battery is required, the bidirectional DC converter such that a direction of a power transfer alternates and supply an alternating current (AC) current having a predetermined frequency to the battery.
