The Capability Evaluation Of Battery For Electric Vehicles Based On ANN

Facing to the pressure of resources and environment , many country are attaching importance to EV(electric vehicles) for it's low consumption and nonpolluting virtue . It is essential that EV competition were the battery competition for EV, economically,fleetly ascertaining capability of batteries become one of research hotspots . Capability of batteries is in the final analysis State Of Capacity (SOC) problem .Via researching work principle of batteries and influence SOC,We put forward mathematics model for SOC, and formula for calculating inner resistance of batteries . We adopt Matlab Neutral Network (NN) toolbox , via emulating mathematics model , and confirm that NN can solve SOC problem . At last we design the structure of NN in this paper . This method can be used to estimate physical chemistry batteries capability .
