    摘要： An acquirer acquires driving data of an electrically-powered moving body. A predictor predicts, based on the driving data of the electrically-powered moving body, an aging failure of an electromechanical transducer including a motor driving a driving wheel of the electrically-powered moving body and a drive circuit driving the motor. The driving data include an input voltage of the drive circuit, an input current of the drive circuit, a rotational speed of the motor driven by the drive circuit, and a rotational torque of the motor. The predictor predicts the aging failure of the electromechanical transducer based on a change of a value statistically representing a relationship between an input electric power of the drive circuit, obtained based on the input voltage and the input current of the drive circuit, and a shaft output power of the motor, obtained based on the rotational speed and the rotational torque of the motor.

    摘要： Disclosed are a user type identification method, an electronic device, and a readable storage medium. The method includes: obtaining driving data in a preset time period, where the driving data includes at least a driving time, an accumulated driving mileage, and a driving speed in a vehicle driving process; obtaining to-be-analyzed data based on the driving data in the preset time period, where the to-be-analyzed data includes daily driving duration, a daily driving mileage, and a quantity of times of driving at each moment daily; and performing analysis on the to-be-analyzed data through a preset identification model, to obtain a user type.

    摘要： Provided is a circuit including a switching transistor having a control terminal configured to receive a control signal and having a current flow path therethrough. The switching transistor becomes conductive in response to the control signal having a first value. The current flow path through the switching transistor provides a current flow line between two nodes. In a non-conductive state, a voltage drop stress is across the switching transistor. The circuit comprises a sense transistor that is coupled to and a scaled replica of the switching transistor. The sense transistor has a sense current therethrough. The sense current is indicative of the current of the switching transistor. The circuit includes coupling circuitry configured to apply the voltage drop stress across the sense transistor in response to the switching transistor being non-conductive. In the non-conductive state, the voltage drop stress is replicated across both the switching transistor and the sense transistor.
