Research on Bench Test of Dual-motor Planetary Coupled Drive System

In order to study the efficiency characteristics and mechanical properties of a dual-motor planetary coupled drive system, this paper develops a test platform for the drive system bench test and data analysis. Tests include external characteristic test of the system and output efficiency performance test during single motor drive mode and dual-motor coupling drive mode. The test results show that the test platform can effectively achieve the system performance test. While satisfying the vehicle driving power requirements, dual-motor planetary coupled drive system can effectively extend the range of power train efficiency zone.
