Title:
OVER-TEMPERATURE PROTECTION METHOD FOR ELECTRIC DRIVE SYSTEM, AND VEHICLE AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/040349
Kind Code:
A1
Abstract:
Disclosed in the present application is an over-temperature protection method for an electric drive system. The method comprises: acquiring temperature data of an electric drive system; determining, according to the temperature data of the electric drive system, whether an over-temperature protection condition is met; if the over-temperature protection condition is met, obtaining a first limiting power and a first limiting torque of an electric motor according to the temperature data of the electric drive system; and limiting the output of the electric motor according to the first limiting power and the first limiting torque. Further disclosed in the present application are a vehicle and a computer-readable storage medium. By means of the present method, the problem of the protection provided by an existing over-temperature protection strategy for limiting the power of an electric motor not being comprehensive is solved, thereby improving the driving safety and reliability.
