The invention discloses a pure electric vehicle storage battery fuse ablation detection control method, device and equipment, and relates to the technical field of vehicle intelligent control, the method comprises the following steps: obtaining a vehicle state, and when a vehicle is in an ON gear and charging operation is carried out, waking up a DCDC converter based on a vehicle control unit and driving the DCDC converter to work; and based on the voltage difference value between the voltage at the output end of the DCDC converter and the actual working voltage of the low-voltage storage battery, detecting and judging the fault of the DCDC converter and the ablation fault of the anode fuse of the storage battery. According to the invention, the fault of the DCDC converter and the ablation fault of the anode fuse of the storage battery can be found in time.
