In the forthcoming operation of smart charging and swapping service network for electric vehicle（EV）， the management of batteries within this special operating mode is still a big challenge. The main issues of battery management are analyzed and clarified and a systematic solution framework based on internet of things（IOT） is proposed with an overall explanation through the sensing layer， network layer and application layer. Different dedicated techniques are selected to deal with different scenarios of batteries， i.e. inside station， outside station and logistics. The implementing methods are treated with consideration of the reality to solve especially the problems of identification within overall scenarios， dynamic stocktaking， grouping management， general and comprehensive analysis， and security measures.
