Embodiment 1
[0062] A method for checking the traction motor power of an electric vehicle is implemented according to the following steps:
[0063] a. Maximum speed power estimation: if figure 1 As shown, the following calculation is done in the first estimation module 1 to output the motor power estimation value P at the maximum vehicle speed motor1 , then P motor1 Value input takes the most value module 4,
[0064] The first estimation module 1 inputs the full load mass, rolling friction coefficient, air drag coefficient, transmission efficiency, vehicle speed and windward area as reference quantities, and then calculates the estimated value P of the motor power at the maximum vehicle speed motor1 ;When in use, only need to input relevant parameters, you can get the desired result;
[0065] In the calculation of the first estimation module 1, the driving force of the vehicle is mainly to overcome the friction force and air resistance, and the traction power P of the vehicle is t Expr...
