The invention discloses a low-voltage power supply system and method for a new energy automobile. The low-voltage power supply system comprises a main power supply, a standby power supply, a main charging unit and a wireless charging unit. When the main power supply is lack of electricity or breaks down, the positive electrode of the standby power supply is connected with the positive electrode of the main power supply, the negative electrode of the standby power supply is connected with the negative electrode of the main power supply, and the standby power supply supplies power to the starting unit and the electric appliance load so as to support starting of the new energy automobile. Based on the low-voltage power supply system of the new energy automobile, the possibility that the new energy automobile cannot be started due to the fact that the low-voltage power supply system lacks electricity can be reduced.

    本申请公开了一种新能源汽车的低压供电系统及供电方法。该低压供电系统包括主电源、备用电源、主充电单元和无线充电单元。在主电源发生亏电或故障时,将备用电源的正极与主电源的正极连接,将备选电源的负极与主电源的负极连接,由备用电源为起动单元和电器负载供电,以支持新能源汽车起动。基于本申请公开的新能源汽车的低压供电系统,能够降低新能源汽车由于低压供电系统亏电而无法起动的可能性。
