series hybrid system and performance testing for performance testing of the power supply of the propulsion system how

摘要

This invention is a system and a performance test method for testing the performance of the power source of the series hybrid propulsion unit relates, the generator module; PWM converter modules; A system for the performance test of the EUT with a battery module and a hybrid controller, said hybrid controller and each of the modules are powered by a motor linked to a constant running speed and at the same time produce a desired pattern speed to operate according to the test conditions tester control section for generating a reference speed for the motor; Motor unit for rotating the generator module at a constant RPM motor according to the reference velocity generated; On the basis of the generated running speed pattern during acceleration based on the power profile of the pattern when the pattern profile, the power generation unit and the resulting acceleration and deceleration pattern to generate a power profile during the deceleration and acceleration for applying the load section has the EUT operating the power generated from a three-phase grid-connected inverters for supplying power to the outside of the module, and test the performance of the deceleration when the blood specimen by operating a power from the outside of the power module with the three-phase PWM converter to be supplied to the EUT which includes a load and, among the blood test samples of the performance test upon or by PWM converter module to enable the performance of only the test in any of the battery modules, battery modules, and a PWM converter of the blood specimen of modules, each module and each module performance By testing the combination can reduce the various issues and trial and error that occurs after the vehicle.
