基于中国工况电动车经济性测试的研究

Research on Economic Test of Electric Vehicle Based on CLTC-P

随着中国工况标准GB/T 18386—2021的发布,纯电动车经济性测试工况正式由中国工况(CLTC-P)代替了欧洲工况(NEDC),并根据CLTC-P推出了缩短法这一测试方法。根据实车测试,对CLTC-P经济性测试及其缩短法测试的有效性进行研究。结果表明:缩短法测试方法相比较常规法测试方法有效的节省测试时间,提升了测试效率,可以计算出CLTC-P低速段的续驶里程,同时缩短法测试较常规法测试续驶里程结果多2.7%,但该工况并不能代表用户实际使用工况,与实际驾驶有较大差异。

With the release of Chinese Driving Cycle Standards(GB/T 18386.1-2021),the driving cycle of pure electric vehicles officially replaced the New European Driving Cycle(NEDC)by The China Light-duty vehicle Test Cycle for Passenger car(CLTC-P),and the shortening test method is introduced according to CLTC-P.Based on the real vehicle test,this paper studies the effectiveness of China’s economic test and its shortening method.The final results show that the shortening test method compared with the conventional testing method is more effective to save test time and improve the test efficiency.Moreover the shortening test method can calculate the driving distance at low speed.The driving distance under shortening test method is 2.7%more than that with conventional method,but the driving condition does not represent the user’s actual driving conditions,which have the significant difference with actual driving conditions.
