Description

technical field [0001] The invention relates to the field of power assembly design on electric vehicles, in particular to a method for checking design parameters of electric vehicle traction motors. Background technique [0002] The traction motor of an electric vehicle is the main power source of the vehicle. Simulation modeling analysis is usually used to verify the design parameters of the traction motor. It is necessary to input the parameters of the traction motor, controller, battery, gearbox, wheels and other powertrain components to calculate the overall Vehicle performance index, the function of verifying by comparing the calculation results with the design parameters. It is necessary to have an in-depth understanding of the technical indicators of components such as batteries, gearboxes, controllers, motors, and wheels, and to master complex parameter settings, which requires a high degree of specialization. The current calibration method is still difficult to ref...
