Disclosed is a vehicle battery temperature increase system, which comprises: an on-board charger including a capacitor, and a bidirectional direct current (DC) converter having a first input/output terminal connected to the capacitor and a second input/output terminal connected to a battery and capable of bidirectional power transfer between the first input/output terminal and the second input/output terminal; and a controller for supplying an alternating current (AC) having a preset frequency to the battery by driving the bidirectional DC converter so that the power transmission direction is alternated when the temperature of the battery is required to rise.

    커패시터와, 상기 커패시터가 연결된 제1 입출력단 및 배터리에 연결된 제2 입출력단을 가지며 상기 제1 입출력단과 상기 제2 입출력단 사이에서 양방향의 전력 전달이 가능한 양방향 직류 컨버터를 포함하는 탑재형 충전기; 상기 배터리의 승온이 요구되는 경우, 상기 양방향 직류 컨버터를 전력 전달 방향이 교번하도록 구동하여 상기 배터리로 사전 설정된 주파수를 갖는 교번 전류를 공급하게 하는 컨트롤러를 포함하는 차량용 배터리 승온 시스템이 개시된다.
