Multifunctional performance test bed for electric vehicle

Abstract

The invention provides a multifunctional performance test bed for an electric vehicle. The multifunctional performance test bed comprises a test system, a tested system, a test bed supporting structure, a control system, a data collection system and an electric system. The test system comprises a power-measuring motor, a speed increasing device, a first flange plate, a torque sensor, a second flange plate, a bearing base, a third flange plate and an intrusiveness coupling which are sequentially connected. A tested gear shift executing mechanism is integrally arranged on the speed increasing device. The tested system comprises a gearbox and a tested motor which are connected with each other. A tested gear shift executing mechanism is integrally arranged on the gearbox. The test bed supporting structure comprises a base, a test system supporting part and a tested system supporting part. The control system comprises a power-measuring motor controller, a power-measuring control unit, a tested motor controller and a tested vehicle controller. By means of the multifunctional performance test bed, all the tests for testing the electric vehicle can be finished, the test system and the tested system are arranged on the test bed supporting structure through sliding blocks, and installation and movement are facilitated.

Description

technical field [0001] The invention relates to the field of testing and testing of electric vehicles, in particular to a multifunctional performance test bench for electric vehicles. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power battery and driven by a motor. The performance of the motor, the performance of the motor controller and the matching between the two are directly related to the power and economy of the electric vehicle. Since the working range of the vehicle belongs to the surface working condition, the working range of the motor is very wide. Therefore, the output end of the motor is required to be equipped with a gearbox for deceleration and torque increase, which increases the application range of electric vehicles, so that the motor can always work at high efficiency. Area. The power performance test of the motor, the performance test of the motor controller, the matching performance test of the moto...
