hi TI技术团队:
我这边使用BQ40Z80电量计进行了3个项目，之前2个项目使用上传电芯测试数据普匹配化学ID使用的，非常顺利； 最新的项目是新电芯体系，没有匹配到合适的化学ID;
我们就按照流程申请了定制化学ID, 定制 ID 7778(ChemID #7778文件定制信息）；但我们使用这个ID 进行学习测试时，发现QAMX重复多次都不更新，学习测试进度异常（目前配置参数GG.gg文件）；然后我又用定制化学ID的电芯进行了测试数据采集（roomtemp_rel_dis_rel文件），与最新的TI 化学ID库匹配，匹配出来的3%以内的ID并没有ID 7778这个（GPC_report文件）； 其它匹配的ID 电压平台是4.4V, 与我们这个电芯4.35V是不同的，也不能使用；
我们想知道，定制的这个ID 7778为什么与电芯测试数据匹配ID没有形成一致，目前我们应该怎么解决这个问题；请提供技术支持，谢谢
