摘要
电动汽车的普及是锂离子电池的主要需求来源之一。而电动汽车的充电性能是影响普及进程的一个重要的考量参数。在材料体系不变的情况下,取代传统恒流恒压充电策略的新型充电策略近10年内也吸引了很多研究者的关注。另外,新一代电池管理系统也对充电策略提出了更高的要求。本文阐述了各种优化的充电方法及其特点和应用。研究结果表明,与传统的恒流恒压充电策略相比,优化的充电方法可以减少充电时间,改善充电性能并有效延长电池寿命。最后,本文还提出了对未来优化充电策略的展望,希望未来在线辨识和实时更新的模型参数的方法或者通过在线的方法辨识特征信号带来更加强大的充电策略。
The popularization of electric vehicles is one of the main sources of demand for lithium-ion batteries.The charging performance of electric vehicles is an important parameter that affects the popularization process.With the same material system,a new charging strategy that replaces the traditional constant current and voltage charging strategy has attracted many researchers’attention in recent years.In addition,the new generation of battery management systems stipulates higher requirements for charging strategies.This article describes various optimized charging methods and their characteristics and applications.The research results show that,compared with the traditional constant current and voltage charging strategy,the optimized charging method can reduce charging time,improve charging performance,and effectively extend battery life.Finally,this article also proposes an outlook for the future optimization of charging strategies,hoping that online identification and real-time update of model parameters or the identification of characteristic signals through online methods will bring more powerful charging strategies.
