An auxiliary device system battery and a small power load are connected to a first power supply line, and power supply power boosted by a DC/DC converter in a regional ECU is supplied to a second power supply line. The large power load and the capacitor are connected to the second power line, and when the large power load is driven, the capacitor is connected to supply the necessary power supply power and prevent voltage fluctuations. When the ignition device is turned off, the switching circuit is closed, dark current is supplied from the capacitor, and charge is released to prevent degradation. Alternatively, the auxiliary device system battery is connected to the second power supply line side, and when the ignition device is turned off, a dark current is supplied to the first power supply line side using a capacitor or a dedicated circuit.

    辅助装置系统电池和小电力负载连接到第一电源线,并且由区域ECU中的DC/DC转换器升压的电源电力被供应到第二电源线。大电力负载和电容器连接到第二电源线,并且当驱动大电力负载时,电容器被连接以供应必要的电源电力,并且防止电压波动。当点火装置关断时,开关电路闭合,从电容器供应暗电流,并且释放电荷以防止劣化。可替代地,辅助装置系统电池连接到第二电源线侧,并且当点火装置关断时,使用电容器或专用电路向第一电源线侧供应暗电流。
