The Multi-Windings Forward Structure Battery Balancing

A structure for active battery balancing with using Multi-Windings Transformer is presented. Most of applications in electrical vehicles need smart voltage control and high effective battery systems. In generally, the battery stack systems consist of these three parts: management, safety and balancing. In these parts, balancing is the most significant part since the management demands to improve the cycle life, battery storage packs, and power capacity. This paper presents the real-time Multi-Windings Transformer balancing topology forward structure model, simulation, and real circuit implementation with using Texas Instruments Stellaris (R) Launchpad Evaluation Kit (EK-LM4F120XL) with Energia based coding. Also, this paper indicates the emphasis of using forward structure model of Multi-Windings Transformer balancing topology since we use forward structure converter for dimishing the extra energy loses and decrease cost of the system.
