This application relates to the field of new energy vehicle technologies of an electric vehicle, and in particular, to a power distribution apparatus, including: a bus, where the bus includes a first terminal and a second terminal. A branch line is connected between the first terminal and the second terminal of the bus, and the branch line is used to connect to a load. The first terminal of the bus is used to connect to a battery, and the second terminal is used to connect to a second power supply apparatus. The first terminal of the bus is connected to a first circuit protection module in series. The first circuit protection module is configured to: when one of circuits on two sides of the first circuit protection module has an electrical fault, enter in a state in which the circuit on the electrical fault side is not connected to a circuit on the other side. Correspondingly, a vehicle on which the power distribution apparatus is mounted and a fault processing method based on the power distribution apparatus are further provided. By using technical solutions of this application, power distribution of a low-voltage power supply system at a low cost can meet high availability and high safety requirements for operation under faults.
