The invention provides a reliability testing method for a range extender system, and relates to the technical field of range extender testing. The reliability testing method of the range extender system includes: obtaining the universal characteristic data of the fuel engine and the efficiency data of the generator, and obtaining the matrix array of the range extender system according to the universal characteristic data of the fuel engine and the efficiency data of the generator . According to the matrix array of the range extender system, the minimum fuel consumption rate curve for power generation of the range extender system is obtained. Determine the rotational speed and generating power of multiple working condition points on the minimum fuel consumption rate curve for power generation. Testing the reliability of the range extender system based on the speed and power generation corresponding to multiple working conditions can make the reliability test results of the range extender system more accurate and ensure the reliability of the range extender under actual operating conditions .
Description
technical field [0001] The invention relates to the technical field of range extender testing, in particular to a reliability test method for a range extender system. Background technique [0002] The range extender is an essential device in the range-extended electric vehicle. It can convert the kinetic energy generated by the fuel consumption of the fuel engine through the generator into electrical energy and output it to the battery for storage, so as to increase the cruising range of the electric vehicle. The reliability of the range extender system is directly related to the reliability of the vehicle, and the reliability test of the range extender system is particularly important. [0003] In the prior art, the reliability of the range extender system is tested by running the fuel engine alternately between the lowest generating speed and the highest generating speed. [0004] However, due to the actual operation of the range extender system, different power generatio...
