The invention relates to a pre-charging fault diagnosis method, device, equipment and medium, and the pre-charging fault diagnosis method comprises the steps: obtaining a pre-charging fault record of a vehicle and a plurality of signal data of the vehicle before and after the pre-charging fault record is generated, and the pre-charging fault record is generated when the vehicle monitors a fault in a pre-charging process; a diagnosis condition corresponding to fault data in the pre-charging fault record is determined, target signal data corresponding to the diagnosis condition is determined in the multiple pieces of signal data, and the target signal data is battery data; and performing pre-charging fault diagnosis according to the target signal data to diagnose whether the pre-charging fault record is a false alarm record. According to the method provided by the invention, the pre-charging fault can be diagnosed, the safe operation of the battery system is ensured, and the safety of the electric vehicle is improved.
