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.
一种用于车辆的增加电池温度的系统,包括:车载充电器,该车载充电器具有电容器和双向直流(DC)转换器,该双向直流转换器具有连接至电容器的第一输入端子/输出端子和连接至电池的第二输入/输出端子并且被配置为在第一输入/输出端子与第二输入/输出端子之间进行双向功率传输;以及控制器,当需要电池升温时,该控制器驱动双向DC转换器,使得功率传输的方向交替,并且向电池供应具有预定频率的交流(AC)电流。
