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.

    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.
