Research and verification of energy consumption and E-range of heavy-duty plug-in hybrid electric vehicle

The evaluation method of energy consumption and E-range of heavy-duty plug-in hybrid electric vehicle is mainly composed of test cycle, test procedure and calculation method of test result. At present, there are some problems in the national standard being implemented at present. Combined with the research results in the process of national standard revision, this paper comprehensively optimizes the evaluation method and carries out experimental verification. In terms of test cycle, the reasons for the application of China automotive test cycle are analyzed. In terms of test procedure, the deadline conditions of each test phase are analyzed, which makes the test more operable. In terms of calculation methods, based on UF, the method of each phase and comprehensive energy consumption, as well as energy consumption conversion, are analyzed. The test results show that, after the optimization of the evaluation method, the electricity consumption of the phase I increases by 78.99%, the fuel consumption of the phase III increases by 19.58%, and the E-range decreases by 39.06%. At the same time, the comprehensive energy consumption of the vehicle is obtained. After considering the conversion of electricity consumption, the fuel consumption increases significantly, among which, the simple conversion method increases the lowest, while the carbon dioxide emission conversion method increases the highest with an increase of nearly 51%.
