Research on Low-Temperature Energy Consumption Test Procedures of Bev Based on Road Travel Data

The reduction of driving range of electric vehicles in winter is a key issue that affects the promotion of new energy vehicles and the implementation of “Carbon peak and carbon neutral” strategic goals. In this study, typical battery electric vehicles in Changchun were selected to obtain the actual road driving data, to analyze the travel and charging temperature, travel characteristics in winter. Two typical temperatures are recommended for the test: take −10℃ as the general and −20℃ as the limit environmental temperature. Finally, based on the driving characteristics, it proposed a low-temperature energy consumption test can better reflect the actual road energy consumption level of BEV in low-temperature.
