锂离子电池组主动均衡参数优化
Optimization of active balancing parameters for Li-ion battery pack
摘要
Abstract
There were many parameters but no quantitative research on the online balancing of Li-ion battery packs.The active balancing experiments under different initial capacity difference,current ratio and balancing threshold were proposed,the active balancing test platform was built.The balancing effect was improved by increasing the balancing current ratio and balancing time ratio.When the main circuit current was 2.00 C and the initial capacity difference reached 15％ or higher,both balancing current ratio and balancing time ratio were close to 0.The balancing effect was improved by suitable reduction of the balancing threshold.关键词
