【摘要】 针对锂离子电池制造工艺和使用环境不同所引起的单体不一致性问题,本文设计了一种主动均衡系统方案。该系统基于双向反激式变压器的均衡拓扑电路,搭载有数据采集和均衡控制芯片,主控制器采用MC9S08DZ60单片机。基于该主动均衡系统,设计实现了基于电压的均衡控制策略。实验结果表明,所设计的主动均衡系统能够满足电池系统均衡需求。更多还原

【Abstract】 Aiming at the inconsistency problem among cells in lithium-ion battery pack caused by manufacturing process and operation environment,an active equalization system scheme has been designed.The equalization topology circuit is based on a bi-directional flyback transformer,with the chip MC9 S08 DZ60 used as the main controller,and this is equipped with data acquisition chip and equalization control chip.Then,a voltage-based equalization control strategy has been designed and realized on the active equalization system.Experimental results validate that the active equalization system and equalization control strategy satisfy the requirement of equalization operation for battery pack.更多还原
