Since the battery was invented in the past 200 years, battery management system has been the use of fixed series-parallel system architecture, that many small-capacity unit cells connected in parallel to be a batteries-cell system according to the requirements load. However, due to the differentiations caused by production conditions and operating modes, this fixed batteries series-parallel system architecture system brings a lot of application problems, such as SOC and SOH uncertainty problem, the battery charge and discharge unbalance problem, safety issues, and low reliability. Energy internet and cyber-physical system (CPS) are believed to be the solution for the future of energy system. With the software-defined method, the software-defined approach was applied to meet the integration requirement of cyber-energy infrastructure for information and battery. In this paper, the author is mainly focused on the disruptive energy battery system design that the battery cell topology can be dynamically reconfigured in the real-time fashion based on the current condition (in terms of the state of charge and the state of health) of battery cells. Besides, the author has also described the battery system design theory based on the close integration of energy flow and information flow and its application in the relevant field.
