New battery dynamic model: Application to lead-acid battery

This paper presents a new method for modeling electrochemical systems taking advantage of analogies with familiar concepts in physics of semiconductors and electrical engineering. This approach to physical phenomena occurring in the most general transient functioning of a battery introduces an original structure in form of non linear RC network corresponding to a flexible and efficient model. This structure can be used to reproduce or predict the behavior of electrochemical cells in fully random operating conditions. The work presented here has been applied in the case of lead-acid batteries. It is thus particularly suited for use in renewable energy systems in remote site or at mini decentralized.
