Abstract: An active heating method for an electric motor, an apparatus, a device, a storage medium and a program product. The method includes: receiving a heating instruction sent by a heat management system, where the heating instruction includes a heating power; inputting a current to the electric motor and adjusting a phase of three-phase pulses according to the heating power; continuously detecting an electric motor iron loss power, determining a difference between the electric motor iron loss power and the heating power, and adjusting a phase difference of the three-phase pulses according to the difference between the electric motor iron loss power and the heating power until the difference between the electric motor iron loss power and the heating power is less than a preset value, to realize active heating of the electric motor.

Abstract: Disclosed are a vehicle-end charging control guidance circuit, a circuit board and a vehicle. The vehicle-end charging control guidance circuit includes a charging guidance module, and the charging guidance module includes a switching unit, a differential charging guidance circuit and a common charging guidance circuit. The switching unit is configured to conduct the differential charging guidance circuit corresponding to a charging interface standard of a power supply device in the charging guidance module when receiving a switch control signal. The charging guidance module is configured to transmit a charging signal between the power supply device and a microprocessor by a conducted differential charging guidance circuit and the common charging guidance circuit.

Abstract: Disclosed herein are a method and a device for remotely diagnosing vehicle faults, a vehicle and a computer storage medium. The method includes monitoring vehicle data uploaded by the vehicle in real time via a cloud platform, and determining whether to identify a preset fault abnormal signal identification from target data of the vehicle data. The method also includes, in response to the fault abnormal signal identification being identified from the target data, sending a fault diagnosis task to the vehicle according to the target data, and receiving diagnosis result data returned by the vehicle after the fault diagnosis task is executed locally by the vehicle. The method further includes generating a remote fault diagnosis result of the vehicle according to the vehicle data and the diagnosis result data.

Abstract: Disclosed are a method and a device for predicting state of health of a battery, an electronic equipment and a readable storage medium. The method includes: obtaining battery data of a vehicle; performing feature extraction on the battery data to obtain a vehicle-using behavior feature corresponding to the vehicle; predicting and obtaining a predicted vehicle-using behavior feature of the vehicle in a next time step according to the vehicle-using behavior feature; and predicting and obtaining a health degree of the battery in the vehicle according to the predicted vehicle-using behavior feature and a battery health state prediction model.

Abstract: Disclosed are a consistency evaluation method for a vehicle battery cell, a device, an equipment, and a storage medium. The method includes: acquiring vehicle operation data, and selecting effective cell data in the vehicle operation data according to a preset effective data standard; processing the effective cell data according to a preset cell consistency index processing method to obtain cell consistency index data; determining a total index deviation value of all battery cells in the current vehicle according to the cell consistency index data; and if the total index deviation value exceeds a preset deviation threshold, determining a consistency risk of the current vehicle.
