According to first-stage power supply, a DCDC converter converts high voltage of a vehicle power battery into low voltage, and the low voltage is supplied to a whole vehicle through a rear intelligent power distribution module; the DCDC converter is also connected with the storage battery through the rear intelligent power distribution module; in the first-stage power supply, the rear intelligent power distribution module is further connected with the front intelligent power distribution module, the rear vehicle body domain controller and the first electric appliance. According to the second-stage power supply, a rear intelligent power distribution module is connected with a front intelligent power distribution module, and the front intelligent power distribution module is connected with a front vehicle body domain controller and a second electric appliance. According to the third-stage power supply, the rear vehicle body domain controller and the front vehicle body domain controller are the last stage of the intelligent power supply system, and the rear vehicle body domain controller and the front vehicle body domain controller are connected with various sensors, switches and loads respectively. A regional power distribution method is adopted, nearby power distribution of electric appliances of the whole vehicle is achieved, and the length of wiring harnesses of the whole vehicle is reduced.
