High-voltage fault prediction method, device and equipment and storage medium

The invention provides a high-voltage fault prediction method, device and equipment and a storage medium, and relates to the technical field of automobiles, and the method comprises the steps: judging the on-off state of a relay connected with a connection loop between a motor and a bus when it is detected that the motor works in a power generation mode; when the on-off state is a conducting state, whether active discharging is carried out on the bus is detected; when it is detected that the bus is not actively discharged, bus voltage values at the two ends of the bus are obtained; and predicting whether a drive circuit of the motor has a high-voltage fault based on the bus voltage value. When the motor generates power, the generated electric energy is transmitted to the bus through the relay and the bus does not discharge, whether the driving circuit of the motor has a high-voltage fault risk or not is predicted through the voltage values of the voltages at the two ends of the bus.
