With the rapid development of electric drive systems, especially new energy vehicles, the issue of electromagnetic compatibility has received more and more attention. The electric drive system of new energy vehicles has the characteristics of high voltage, high current, complex structure, and diversified coupling paths, and is the main source of interference.The electric drive EMC/EMI test system under simulated actual load conditions is composed of an anechoic chamber, a dynamometer system, a battery simulator, a power amplifier and its shielding room, a control room and its shielding room, a cooling system, and a shielding shaft system. According to the requirements of CISPR25, GB/T18655, GB/T36282, GB/T18387 and other standards, it can meet the conduction emission, radiation emission and radiation immunity, high current injection and other tests of battery packs, motors, controllers, powertrains, ecc. .
The vehicle axle coupling dynamometer test system consists of a mobile low-inertia electric dynamometer, dynamometer driver, battery simulator, electrical control cabinet, measurement sensors, vehicle windward cooling system, traffic real-life simulation system, main control computer, electrical Control cabinet and other components.The dynamometer can perform speed and torque control to simulate road load. Load simulation methods include: constant torque control, calculated road spectrum simulation, actual road spectrum import, and user-defined load spectrum. The power analyzer measures the current, voltage and power of each energy consumption unit of the tested vehicle, analyzes the energy flow of the vehicle under different operating conditions, and draws the energy spectrum of the entire vehicle. The dynamometer adopts a low-inertia dynamometer, which has extremely high dynamic characteristics and can simulate rapidly changing working conditions and simulate different road models. By integrating into the traffic scene simulation system, real vehicle actions under different road conditions can be truly reproduced, including the driver's operating comfort. The system can also be transformed into a powertrain test system, and the battery simulator can be connected to the powertrain drive to test the powertrain.
The vehicle EMC/EMI test system generally consists of an anechoic chamber or reverberation chamber, measuring
instruments, and a hub dynamometer system that simulates the road load of the vehicle. The rotating hub dynamometer
system that simulates vehicle load can be designed as a two-wheel drive, four-wheel drive or more shaft drive
dynamometer according to the number of drive shafts of the vehicle. The dynamometer system can also adopt a
structural type embedded in the turntable, or a mobile type.
The high-speed reducer test bench consists of a low-inertia load analog dynamometer, a high-speed compact drive motor, a frequency converter, an environmental chamber, a cooling system, a high-precision sensor, a vibration monitoring and early warning system, a mechanical system, a real-time control system of the dynamometer, and a main control System and other parts. For the electric drive powertrain test bench, there is no need for high-speed drive motors, only low-inertia load simulation motors. The real-time dynamic control system can realize the speed and torque control through the real-time controller and simulate the actual load. The main control system can communicate with the environmental chamber, power analyzer, cooling system, EUT, etc., and realize control. The data acquisition system collects signals from torque sensors, vibration sensors, temperature sensors, pressure sensors, and other sensors, and transmits them to the main control system at a high speed. The sensor data can be displayed, saved and processed in the software interface.
We provide customized test test systems for aviation high-speed transmission systems, such as high-speed generators, high-speed transmission boxes, ecc. Various types of shafting, dynamometer systems and electrical loads can be designed according to actual needs.
