Research on Test and Evaluation Technology of Hybrid Power Unit

With the adjustment of the strategic planning of China's automobile industry, the national policy strongly supports the development and large-scale application of hybrid power technology, but there is no guidance document on the testing and evaluation standards of hybrid power units. In this paper, the current situation of testing and evaluation technology of hybrid power units at home and abroad is analyzed in detail, and combined with the working characteristics of hybrid power units, the testing and evaluation methods that are more in line with the working characteristics of hybrid power units are put forward. They are the individual test of hybrid power unit parts, the test method of independent control of engine load and motor load, and the test method of total load control of hybrid power unit.
