The invention relates to a comprehensive performance test bench of an electromobile, which comprises a drive axle, a transmission, a clutch, a drive motor, a controller and a storage battery bank, wherein the controller is connected with the drive motor by a wire, and connected with the storage battery bank by a wire; the controller is also connected with an accelerator pedal and a brake pedal respectively by wires; the drive motor is connected with the clutch; the clutch is connected with the transmission; the transmission is connected with a main reducing gear by a transmission shaft; and a plurality of loading balancing weights simulating different loads of a vehicle are arranged at the left end and the right end of the drive axle respectively. The eight loading balancing weights are cast by high-strength spheroidal graphite cast iron. The test bench simulates the different loads of the vehicle, tests parameters such as operating speed of the vehicle under different load conditions, working current of the storage battery bank, terminal voltage of the storage battery bank and volumetric change of a storage battery during use, and detects drive capability of the drive motor, and usability of a driver and the storage battery bank.
Description
technical field [0001] The invention belongs to the field of power electronics and automation, in particular to a test bench for testing the performance of electric vehicles, in particular to a comprehensive performance test bench for electric vehicles. The device can simulate electric vehicles under different load conditions to conduct comprehensive detection of motor performance, storage battery performance and controller performance. Background technique [0002] With the country's policies to encourage electric vehicle companies and the introduction of financial subsidy policies for ordinary people to purchase electric vehicles, electric vehicles produced by electric vehicle manufacturers have increasingly become the means of transportation for ordinary people. The main components of electric vehicles are drive motors, controllers and battery packs. The quality of electric vehicles is difficult to measure by the quality of one or two of the drive motor, controller and b...
