BQ27Z746: 250mAh磷酸铁锂电池,匹配的化学ID偏差大于4%。但已经学习成功。

Part Number: BQ27Z746
Other Parts Discussed in Thread: GPCCHEM, BQ40Z50

250mAh磷酸铁锂电池,匹配的化学ID偏差大于4%。能学习成功学习后的电池容量有280mA左右,但0.2C放电到末端,SOC还有30%电量。

这样是不是要重新定制ID.

  • 您好,方便将GPCCHEM 报告和学习成功的log数据和有问题的log数据发过来看一下。

    您好,以上是GPCCHEM 报告和学习成功的log数据和有问题的log数据。

    另外有广东地区的FAE的联系方式吗。公司这个项目马上开始进入样品阶段,自制的电芯方案确定想定制专用的的ID。

    以前三元电芯做笔电,用的是BQ40Z50 R3 GPCCHEM 报告中匹配的ID中最大错误基本都是0.8%以下。学习也都是100%成功,量产都没有问题。

  • BQ27Z746-M11390L1-1S1P_ID481-250mAh-3.65V-The SOC is correct after changing Term Voltage from 2.55V to 2.7V.log

    您好:将Term Voltage","2550","mV"从2.55V更改为2.7V后,SOC才正确显示。

    以上是最新的LOGO数据。

  • 您好,三分报告中有一个报告推荐使用Best chemical ID : 482就可以,应该不需要专门定制ID
