Method for testing braking energy recovery strategy of electric vehicle

The invention provides a method for testing a braking energy recovery strategy of an electric vehicle, and the method comprises the steps: arranging a chassis dynamometer below a to-be-tested vehicle, and arranging a pedal limiter and a wiring displacement sensor on a brake pedal, analog signals obtained by testing of the chassis dynamometer and the wiring displacement sensor are acquired through a data acquisition device; carrying out a chassis resistance test and a mechanical brake wheel edge force test through neutral gear sliding to obtain neutral gear sliding chassis resistance and a whole vehicle mechanical brake wheel edge force; testing the wheel rim force of the whole vehicle according to the deceleration working condition to obtain the wheel rim force of the whole vehicle under the deceleration working condition; and according to the neutral gear sliding chassis resistance, the whole vehicle mechanical brake wheel rim force and the whole vehicle wheel rim force under the deceleration working conditi
