The invention relates to the technical field of new energy vehicles under electric vehicles, in particular to a power distribution device, which comprises a bus, a power distribution unit and a power distribution unit, and is characterized in that the bus comprises a first end and a second end; a branch line is connected between the first end and the second end of the bus and is used for connecting a load; the first end of the bus is connected with a battery, and the second end is connected with a second power supply device; the first end of the bus is connected in series with a first circuit protection module; the first circuit protection module is configured to be in a non-conducting state from the electrical fault side circuit to the other side circuit when one side circuit of the two side circuits of the first circuit protection module has an electrical fault. The invention further correspondingly provides a vehicle provided with the power distribution device and a fault processing method based on the power distribution device. According to the technical scheme, the power distribution of the low-voltage power supply system can meet the high-availability and high-safety requirements of operation under the fault condition at low cost.
