Driving range has become a core development objective for New Energy Vehicles (NEVs). To optimize range, engineers require a detailed understanding of energy consumption across individual components. Intelligent thermal management plays a pivotal role in extending driving range.
Furthermore, modern powertrain test systems must support a wide array of scenarios—from performance testing and strategy validation to special road condition simulation, failure mode analysis, and electrical accessory evaluation.
The JKT Powertrain Test System features high-dynamic dynamometers directly coupled to the vehicle wheel hubs to simulate road loads. JKT provides dynamometer systems capable of simulating extreme temperature environments and solar radiation, enabling comprehensive testing of the complete vehicle.

Developed for powertrain systems of new energy vehicles, hybrid vehicles and construction machinery vehicles, this system supports full-range tests on motors, reducers, gearboxes and vehicle three-electric integrated powertrains, covering performance, durability, efficiency, NVH and high-low temperature coupling tests. Equipped with high-precision sensor units, it achieves a test accuracy of ±0.05%FS and features fast dynamic acquisition response for speed and torque. It can accurately restore national standard driving cycles such as WLTC and NEDC as well as customized extreme working conditions, eliminating the site and weather limitations of real vehicle road tests and delivering highly repeatable and reliable test data.
（2）Four-quadrant Energy-saving Operation, Significant Cost and Efficiency Optimization
Adopting self-developed four-quadrant AC dynamometer technology, the system supports bidirectional loading operation of powertrains and perfectly simulates full-scene driving conditions including vehicle starting, acceleration, coasting and regenerative braking. The electric energy feedbacked during testing can be recycled internally, and redundant power can be grid-connected. Compared with traditional test equipment, it greatly reduces long-term test energy consumption and operating costs, fully meeting enterprises’ demands for large-batch and long-duration durability tests.
（3）High-compatibility Intelligent Integration, Suitable for Industrial R&D
Designed with a modular architecture and independently controllable domestic core components, the equipment features excellent compatibility and can flexibly connect with third-party calibration and test devices such as battery simulators, climate simulation chambers, power analyzers and INCA tools. Matched with self-developed intelligent measurement and control software, it supports automatic test script editing, unattended durability tests, multi-format data export and visual analysis, which greatly shortens the R&D and calibration cycle of powertrains and reduces R&D and test risks.
（4）Full Standard Compliance, Adaptable to Multi-industry Certification
The system fully complies with domestic and international automotive powertrain test standards including GB/T, IEC, SAE and CISPR25, and can generate compliant and valid test reports. It covers full-scene application requirements such as new product R&D, quality inspection sampling, third-party testing and certification, and product compliance filing, applicable to multiple fields including passenger vehicles, commercial vehicles and special construction machinery vehicles.
