Abstract

本发明公开了一种化成分容过程中输出纹波影响下的容量测量补偿方法，包括：获取目标通道在容量统计窗口内的输出电流序列；识别输出电流序列对应的纹波周期边界，并依据纹波周期边界将容量统计窗口划分为前端残缺周期、中部完整周期区段和后端残缺周期；对中部完整周期区段内的输出电流序列进行积分，得到主体容量值；构建前端局部纹波模板和后端局部纹波模板，将前端局部纹波模板对应于前端残缺周期进行积分获得前端补偿量，将后端局部纹波模板对应于后端残缺周期进行积分获得后端补偿量；将主体容量值、前端补偿量和后端补偿量相加后获得确定最终补偿容量值。本发明提高了化成分容过程中存在输出纹波情况下的容量测量精度。
