The present invention relates to and provides a vehicle power supply device capable of stabilizing the operation of a vehicle load with a minimum electric power when shifting from an idle stop state to an engine restart state. The vehicle power supply device (11) is provided with: a DC-DC converter (14) that converts the voltage of power output from a normal power supply (12); a power storage unit that is connected to the DC-DC converter (14); and a DC-DC control unit (161). When the idle stop function ends, the DC-DC control unit (161) supplies the power converted by the DC-DC converter (14) to either the first vehicle load or the second vehicle load, and supplies the power from the normal power source (12) to the other of the first vehicle load and the second vehicle load.

    本发明涉及并提供一种车辆用电源装置,其在从怠速停止状态移至发动机再起动时,能够以最小限的电力使车辆搭载负荷的动作稳定。车辆用电源装置(11)具备:对从通常电源(12)输出的电力的电压进行转换的DCDC转换器(14)、与DCDC转换器(14)连接的蓄电部、DCDC控制部(161)。DCDC控制部(161)在怠速停止功能结束时,将由DCDC转换器(14)转换的电力供给到第一车辆负荷及第二车辆负荷中的任一方,且将来自通常电源(12)的电力供给到第一车辆负荷及第二车辆负荷中的任另一方。
