The invention provides a low-power-consumption power distribution method with a wide current range. According to the low-power-consumption power distribution method in the wide current range, a low-power-consumption power distribution main circuit comprises a voltage conversion circuit, a control circuit, a mode switching circuit and a VN9D5D20F chip (U7); the voltage conversion circuit is used for converting power supply voltage into working voltage, so that normal communication power supply can be guaranteed; the control circuit is used for controlling the operation of the whole system; and the mode switching circuit is used for switching working modes to avoid abnormal power failure of the ECU. According to the low-power-consumption power distribution method with the wide current range, power can be supplied to the multiple ECUs in the normal working mode, power can be supplied to the multiple ECUs in the low-power-consumption mode in the low-power-consumption mode, seamless switching can be achieved when the low-power-consumption mode is converted into the normal working mode, abnormal power failure of the ECUs can be avoided, and the power consumption of the ECUs is reduced. And meanwhile, the problem of battery feed can be solved.
