New energy motor test bench

The new energy motor test bench is mainly used for routine performance tests, durability and load tests of new energy motors and their controllers, as well as other user-developed research tests (such as: development, testing, and comparison tests of motors or motor controllers), to meet the needs of new energy vehicle project development. The new energy motor test bench can complete the testing work of the performance of electric vehicle motors, provide hardware testing support for users' independent research and development, assist users in improving design schemes, and verify product performance, etc.

New energy powertrain test bench

The new energy powertrain test bench consists of installation foundation and tooling, dynamometer motor, inverter system, battery simulator, real-time measurement and control system, data acquisition system, high and low temperature environmental chamber, constant temperature cooling system, safety monitoring system, control software and auxiliary equipment.

Engine test bench

Engine test benches can be classified according to dynamometer type: eddy current dynamometer, water eddy current dynamometer, and electric dynamometer test benches. Eddy current dynamometer and water eddy current dynamometer test benches are mainly used for engine reliability and durability testing, while electric dynamometer test benches can be used not only for reliability and durability testing but also for engine bench power performance, economy, emission optimization matching, engine component testing, and optimization calibration during engine R&D. They can also be used for dynamic development testing of engines with whole vehicle and road simulation, and for meeting the latest engine product certification tests according to Chinese, American, Japanese, and European regulations.

Vehicle bridge testing platform

The commercial vehicle axle assembly test bench meets the performance requirements for comprehensive performance testing of axle assemblies in relevant national standards.

Transmission test bench

The transmission test bench is currently mainly used for durability and conventional performance tests of passenger car front-wheel or rear-wheel drive transmissions. This test bench generally adopts a traditional "three-motor" structure and is required to meet the requirements of the vehicle mechanical transmission bench assembly test method, including transmission fatigue life test, transmission efficiency test, high-speed test, temperature rise test, and dynamic sealing test.

Hybrid test bench

The hybrid powertrain test bench is mainly used for various tests in the user product development process for the power system (engine + SG motor + transmission + dynamometer) and its electronic control system research and development. It tests the performance of the engine, motor, motor controller, and transmission, providing accurate and reliable test charts and data.

Engine offline test bench

The engine offline test bench is mainly used for batch factory testing of engines by engine manufacturers. Engines coming off the assembly line can be automatically sent to the test bench for automated testing via a pre-assembly line, AGV, and RGV intelligent logistics system.

Transmission offline test bench

The transmission offline test bench is mainly used for offline detection of transmissions, such as DCT, EV, hybrid HEV automatic transmissions, multi-speed reducers and other various transmissions' factory inspection and testing. Transmissions from the assembly line are conveyed to the test station by an intelligent roller track for quick connection and clamping of oil, gas, water and electricity, and testing is performed according to national standards or relevant transmission testing standards, including no-load, load, NVH, and customized operating conditions.

Electric drive assembly offline test bench

The electric drive assembly offline test bench is mainly used for offline detection of the electric drive assembly. The electric drive assembly from the production assembly line is transported to the test station by an intelligent roller track, where quick connection and clamping of oil, gas, water, and electricity are performed. According to national standards or relevant test standards for electric drive assemblies, tests such as no-load, load, electric working conditions, power generation working conditions, NVH, and custom working conditions are conducted.

Electric drive bridge offline test bench

The electric drive axle offline test bench is mainly used for the running-in and offline testing of new energy electric drive axles. Electric drive axles from the production assembly line are sent to the test station by an intelligent roller track or hoisting tool for quick connection and clamping of oil, gas, water, electricity, and the transmission shaft system. According to national standards or relevant test standards for electric drive assemblies, communication tests, partial load tests, NVH vibration tests, noise and abnormal sound detection, ABS performance, and differential function tests are performed.

New energy vehicle motor offline test bench

The new energy vehicle motor offline test bench is mainly used for offline testing of new energy vehicle motors. Motors from the production assembly line are conveyed to the test station by an intelligent roller track for quick connection and clamping of oil, gas, water, and electricity. According to national standards or motor testing standards, online mode qualification testing is performed on the motor.

Container test rig

The container test bench is a one-stop testing platform solution specifically designed for users. Users only need to provide the site for container placement and supporting water and electricity. The container test bench is designed to be mobile, effectively solving the problem of a lack of laboratory for users. The container test bench is a customized service and can provide different solutions based on the different needs of users. Equipment can be placed indoors or outdoors to meet the maximum testing needs of users.

Acceptance inspection completed for the new energy motor drive and controller test system

The new energy motor drive and controller testing system provides a dedicated testing technical solution for motor design, production, inspection, and quality control input. Due to the variety of motors under test, the new energy motor drive and controller testing system adopts a segmented form. Based on the torque and speed parameters of multiple motors, it uses one platform and, by replacing the support and transmission parts, achieves the sharing of one new energy motor drive and controller testing system platform to meet the needs of more motor tests. At the same time, considering the future expansion of other motor test benches, the test platform reserves sufficient dimensions to meet the needs. Through one platform, replace the torque sensor
