The main content of this article is involved in researching SOC of zinc/air battery used in Evs. According to the feature of zinc/air fuel, and some principle of battery discharge, the authors design a set of measurement system on zinc/air battery's energy. By proceeding mimetic Ev's work process, the authors take such steps: precisely measure the value of voltage, current, temperture of the experiments and use ANN to modify the meaure results and compute the discharging energy. And a new method is brought forward, called modified energy-accumulation approach to predict the SOC of zinc/air battery used in Evs and some good results is obtained.
