Consensus Control for Battery Management System

Abstract:

Safety and Reliability are fundamental and challenging problems in the Battery Management System (BMS). To maximize the lifetime of battery, the process of charge and discharge must have to consider consensus. This paper provides a theoretical framework for analysis of consensus control with an emphasis on robustness due to the battery differentiation. A hybrid model is constructed to illustrate the process of updating energy state and topology structure. Based on the model, a consensus algorithm for BMS is proposed. It’s useful for evaluating optimal utilization of battery management at design phase. Related analysis reveals that the energy state of discharge process in battery modules converges to balance. A prototype of simulation was developed according to the constructed model. Simulations results are presented that demonstrate the effects on the speed of consensus algorithms and cooperative control of battery modules.
