The invention relates to a vehicle integrated power supply and a control method thereof. An integrated power supply includes: a first low voltage DC-DC converter (LDC) converting a supply power into a first output voltage and supplying the first output voltage to a first auxiliary battery and a first electrical load connected in parallel with each other; a second LDC converting the supply power into a second output voltage and supplying the second output voltage to a second auxiliary battery and a second electric load connected in parallel to each other; and an integrated controller controlling the first LDC and the second LDC to change an output voltage of the first LDC and the second LDC. The first auxiliary battery and the second auxiliary battery are connected in series, and when the first LDC fails, the second LDC outputs a second increased output voltage higher than the second output voltage according to the control of the integrated controller.

    本公开涉及一种车辆集成电源及其控制方法。一种集成电源包括:第一低压DC‑DC转换器(LDC),将供应电源转换为第一输出电压,并将第一输出电压提供给彼此并联连接的第一辅助电池和第一电负载;第二LDC,将供应电源转换为第二输出电压,并将第二输出电压提供给彼此并联连接的第二辅助电池和第二电负载;以及集成控制器,控制第一LDC和第二LDC以改变第一LDC和第二LDC的输出电压。第一辅助电池和第二辅助电池串联连接,并且当第一LDC发生故障时,第二LDC根据集成控制器的控制输出高于第二输出电压的第二增加输出电压。
