电池是电动汽车的基本组成部分，代表着向可持续移动性迈出的一步。锂化学现在被公认为电动汽车储能的首选技术。然而，仍有几个研究点是开放的。它们包括电池材料的最佳选择以及电子电路和算法的开发，以实现更有效的电池利用。本文首先回顾了用于预测电池性能的最有趣的建模方法，并讨论了适用于电池管理IC和系统的苛刻要求和标准。然后，一个通用的和灵活的架构，电池管理的实施和主要技术的荷电状态估计和充电平衡的报告。最后，我们描述了一个创新的BMS，它采用了几乎完全集成的有源充电均衡器的设计和实施。
The battery is a fundamental component of electric vehicles, which represent a step forward towards sustainable mobility. Lithium chemistry is now acknowledged as the technology of choice for energy storage in electric vehicles. However, several research points are still open. They include the best choice of the cell materials and the development of electronic circuits and algorithms for a more effective battery utilization. This paper initially reviews the most interesting modeling approaches for predicting the battery performance and discusses the demanding requirements and standards that apply to ICs and systems for battery management. Then, a general and flexible architecture for battery management implementation and the main techniques for state-of-charge estimation and charge balancing are reported. Finally, we describe the design and implementation of an innovative BMS, which incorporates an almost fully-integrated active charge equalizer.
