【摘要】：锂离子蓄电池起火等安全隐患的主因在于单体不平衡,针对锂离子蓄电池组在充放电过程中存在的单体间不平衡问题,基于最佳优先思想,提出了一种新型锂离子蓄电池组均衡策略。该策略通过分析锂电池单体电压和容量两大关键特征因素的变化规律,基于最佳优先思想,确定其综合影响程度,寻求均衡最佳路径,实现锂电池充电、放电、搁置等不同状态下的均衡调节,达到锂离子蓄电池组均衡调节的目标,为锂离子蓄电池的可靠供能提供保障。
[Abstract]:The main cause of the hidden danger of lithium ion battery fire lies in the unbalance of the single unit. In view of the imbalance between the monomers in the charging and discharging process of the lithium ion battery group, the best priority idea is used. A new equalization strategy for lithium ion battery was proposed. By analyzing the variation law of the two key characteristic factors, the voltage and the capacity of lithium battery, based on the optimal priority, the strategy determines the comprehensive influence degree of lithium battery, and finds out the optimal path to realize the charging and discharging of lithium battery. The equalization adjustment in different states, such as shelving, can achieve the goal of equalization adjustment of lithium-ion battery group, and provide the guarantee for reliable energy supply of lithium ion battery.
