Product Description

 

New energy motor towing test system

The new energy vehicle motor to-drag test system can meet the performance test of pure electric passenger cars and commercial vehicle motors and their controller systems. The test bench can automatically or manually test the conventional performance, external characteristics, efficiency characteristics, NEDC and other tests of the motor, and can measure the parameters such as power, torque, speed, temperature, etc., so as to calculate the motor performance parameters and draw the relevant curves.

The test bench can complete the stalled rotor torque and stalled rotor current test, temperature rise test, continuous electric working characteristics test, motor maximum speed test, motor overspeed test and feed working characteristics test. At the same time, the test bench can feed back the power generated during the test process to the company's power grid through the frequency conversion system.
The new energy vehicle motor towing test system adopts a modular and integrated design, the operation part is ergonomically designed, and the manual/automatic mode control can be completed, and the driving and loading system is provided by the customer to test the piece.
The system is divided into three parts: mechanical system, simulation support system, electrical system and host computer software system.
1.Mechanical system: the overall platform, quick clamping system, shafting connection part and other equipment.
2.Simulation support system: environmental warehouse, temperature control system and other equipment.
3.Electrical system: bidirectional drive DC power supply, sensor (torque, speed, current, voltage, vibration, temperature) real-time data acquisition system, data acquisition, current sensor acquisition, electrical parameter measurement equipment, alarm system and other equipment.
4.Software system: The upper computer test software is divided into data acquisition communication module, data acquisition setting module, data real-time exchange control module, and data processing module. The host computer completes the functions of test control, data analysis and display, data recording and export according to the test items.

Features:
1.All bench building functions are modular, and test modules can be added or decreased according to the different test objects.

2.The advanced real-time measurement and control system meets the requirements of high precision and fast response of the test system, and is convenient for the software to conduct a comprehensive analysis of the test process data in the later stage.

3.According to the test requirements specified in the national standard, the test items can be increased or decreased according to the configuration module to meet the test items of various types of tests.

4.The compressor refrigeration and heating mode is used as the environmental simulation equipment and temperature control system of the test piece, which simulates the high temperature, low temperature, high humidity and low humidity environment of the test piece, shortens the aging durability test time of the test piece, improves the R&D efficiency and reduces the R&D cycle.

5.Professional motor test bench, fixture with quick docking function, easy to load and unload, can adapt to the installation of different tested motors, the system operation adopts piano table/cabinet + computer table control mode, can complete all test operation layout in a single position.

6.Customized test software, classifying the software interface and process, reducing repeated tests, and greatly improving the work efficiency of testers. It can be used for real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, pass judgment, and report export.
