Problems solved by technology

In the existing electric vehicle test devices, they basically focus on the test of electric vehicle components, and their shortcomings: the detection of regenerative braking electric energy is neglected, or the test results obtained are too far from the actual due to the backwardness of the experimental devices. Lost the guiding significance for design work

The testing bed has the following advantages of simple and reasonable structure, capability of detecting performance and regenerative brake energy during brake of the electric vehicles and practical value for design of the electric vehicles.

Description

technical field [0001] The invention relates to an electric vehicle detection and regenerative braking energy quantitative research test bench which can detect both the performance of the electric vehicle and the ability of the regenerative energy in the braking process of the electric vehicle. Background technique [0002] The range of electric vehicles is very wide, including electric cars. The development of electric vehicles is a breakthrough for the upgrading and leapfrogging of my country's automobile industry, and it is also of great significance for ensuring energy security and implementing energy conservation and emission reduction. In addition to being green and environmentally friendly, electric vehicles have another outstanding advantage: when the car brakes, the motor changes from the original motor to a generator, and part of the energy in the braking process of the car is used to drive the generator to generate electricity, thereby regenerating new electric en...
