Abstract
Considering the disadvantages of mileage billing for electric vehicles under exchanging battery mode, a pow-er measurement method for electric vehicles was proposed in this paper. Accordingly, DC power measurement module and vehicle terminal were developed. By installing DC power measurement module in the battery box of electric vehi-cles, real-time parameters of battery were acquired. As a result, accurate measurement of battery power could be real-ized. On the other hand, vehicle terminal communicated with battery box through CAN bus, providing interactive in-formation view. The DC power measurement module and vehicle terminal are verified and tested under operation mode, which achieve accuracy class 0. 5, and meanwhile, show good reliability and high practical value.关键词
