Abstract
Due to the superior advantages of electric vehicles, its population in China has increased rapidly in recent years, especially in the passenger car field. However, the short cruising range lets its owners cause serious range anxiety, especially using air conditioning in summer and winter. Although the certification results of the energy consumption rate decreased gradually, complaints about the higher energy consumption rate under the real-road driving conditions still exists. To analyze the influence factors on the difference between real-road and certification energy consumption rate, the real-road energy consumption characteristics of electric passenger car driving in Tianjin has been investigated. The real-road energy consumption rates with AC (air conditioner) on and AC off have been compared and the real-road energy consumption rate was also compared with certification energy consumption rate. The influence factors on the difference of the energy consumption rate have been summarized and qualified considering the driving and idling energy consumption rate.
