The invention discloses a high-voltage interlocking fault processing method, device and equipment and a storage medium, and the method comprises the steps that when a high-voltage interlocking loop breaks down and the high-voltage state of a vehicle is the upper high voltage state, the high-voltage interlocking loop is switched to the high-voltage interlocking loop, and the high-voltage interlocking loop is switched to the high-voltage interlocking loop; acquiring the speed of the vehicle, the actual voltage of each piece of high-voltage electric equipment, the voltage of a battery bus and the fault duration time; calculating a voltage difference between each actual voltage and the battery bus voltage; and according to the vehicle speed, the voltage difference and the fault duration time, whether the vehicle is subjected to high-voltage power-off processing or not is determined. According to the technical scheme provided by the invention, whether the vehicle is subjected to high-voltage power-off treatment or not can be determined according to the actual condition of the vehicle, so that the situation that the vehicle breaks down due to direct high-voltage power-off is avoided, and the safety of the vehicle is improved.
