Embodiment 1
[0070] A method for quickly detecting demagnetization of an electric vehicle permanent magnet synchronous motor, specifically comprising the following steps:
[0071] S101:
[0072] The remote service management platform obtains the real-time operation data of each electric vehicle. The present invention mainly focuses on the parameters closely related to the field weakening degree of the permanent magnet synchronous motor, including the accumulated mileage of the vehicle, the state of the driving motor, the speed of the driving motor, the torque of the driving motor, the driving Motor temperature, motor controller input voltage and motor controller DC bus current, and store the above data in the database.
[0073] S102:
[0074] Determine the effective working conditions of permanent magnet synchronous motor demagnetization rapid detection: the state of the driving motor is power consumption, select the temperature range of the motor, which is between 20°C and 50°C, and sele...
