BQ4050 三元锂电芯电压达到3.9V但是SOC为0%

我们有一个用BQ4050的产品，在客户测试，发现SOC为0%但是电压已经达到3.9V，暂时还没有数据反馈。

我们推测会不会是充电电流没有达到阈值，导致SOC没有计算？这个想请问一下BQ4050是否有这种机制，或者说有没有类似案例是什么原因造成的？ 还望大家帮忙解答一下，谢谢。

Star Xu：

您好，建议问一下客户做了哪些测试，是否有reset，reset以后SOC会不准确

Gary Liu4：

客户返回了一个通讯截图和gg文件，从通讯截图来看，3.9V显示22%。gg文件我不知道怎么上传附件， 请查看上一个回复我粘贴过来的信息。

如果是复位按照gg文件里的voltage DOD表更新，应该是在70%到80%之间才对。因为是三元锂电池，如果真的是复位了，根据电压更新应该不太可能有这么大的误差吧？

是否还有其他可能性？烦请帮忙解答一下，谢谢。

,

Star Xu：

您好，reset 以后，会强制soc到7%当电压达到EDV2, SOC到3%当电压达到EDV1, SOC 0%当电压达到EDV0

,

Gary Liu4：

客户说只是充满，没有复位操作。那这样还有什么可能性吗？请帮忙看下，谢谢。

,

Star Xu：

您好，建议您将电池充电并且log数据确认问题。

Gary Liu4：

Gary Liu4：

我们的产品上4个led是由bq4050控制的，现在只亮两个。然后上一个回复里的txt是客户log的数据，可以看到SOC为55%但是cell电压为4078mV。

我们了解到客户在使用过程中可能不会充满和放空，这样的话我们怀疑这个SOC误差是否是因为没有满充满放造成？

另外现在客户的这种情况，是否能通过某种途径(除了复位以外)来让电池通过gg file里的DOD电压表更新一下SOC? 

请帮忙解答一下，谢谢。

,

Star Xu：

您好，如果怀疑SOC误差是否是因为没有满充满放造成，建议您实际验证一下。
您可以看一下参数的DOD表，Voltage 50% DOD的电压对应的多少。如果误差很大，可能和CEDV Profile 1的参数有关。
