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.
