Battery systems are inherently networked systems, in which batterycells or packs are grouped by serial and parallel connections tomeet power and capacity specifications. In real-time operation,battery packs must be controlled collaboratively so that theircapacities can be fully utilized. By employing both analogcharge/discharge currents and discrete-event bypass switches innetworked battery systems, we present a new hybridcontrol methodology to estimate and control the states of charge (SOCs) andoptimize performance. Necessary andsufficient conditions for controllability under hybrid controlmechanism. These conditions are then used to derive controlstrategies to achieve coordinated SOC control, state consensus,and performance optimization. Control algorithms are developed,their convergence properties proved, and optimality established.Simulation examples are used to demonstrate the methods and theirperformances.
