An object of the present invention is to facilitate starting a vehicle when a low-voltage battery in the vehicle runs out of power. The electrical junction box (10) is equipped with a special simplified power supply (25). Internal circuitry of the electrical junction box (10) provides an output of the simplified power supply (25) as an operating voltage of the DC/DC converter to activate the DC/DC converter when the low voltage battery is depleted. When the DC/DC converter is activated, high-voltage power stored in a high-voltage battery on the vehicle may be dropped and supplied to a circuit on the low-voltage battery side, thereby enabling a normal start operation, such as starting an engine, to be performed. The emergency start mode may be selected by a user's switching operation or by automatically detecting a supply voltage drop.

    本发明的目的是当车辆中的低电压电池电量耗尽时便于启动车辆。电接线盒(10)配备有特殊的简化电源(25)。电接线盒(10)的内部电路提供简化电源(25)的输出作为DC/DC转换器的操作电压,以在低电压电池耗尽时激活DC/DC转换器。当DC/DC转换器被激活时,存储在车辆上的高电压电池中的高电压电力可以被降压并被供应到低电压电池侧的电路,从而使得能够进行正常的启动操作,例如启动发动机。可以通过用户的开关操作或者通过自动检测电源电压降来选择紧急启动模式。
