是否可以在STC3115中调整SOC值表

嗨，
默认OCV表在STC3115中进行了硬编码（与STC3117相比，其中表可由用户完全配置）。如果选择* IJT或* AIJT芯片版本，表值会有所不同。
以下文档中的OCV曲线显示了电池OCV特性可能的最小值/最大值。
 
https://github.com/st-sw/STC3115GenericDriver/blob/master/Docs/Config/STC3115%20OCV%20curve%20-%20default%20register%20values.pdf
只要电池的完整OCV曲线位于最小值和最大值之间，您就可以从电量监测计获得良好的SOC精度。
在本文档的第3页，您可以看到对于STC3115IQT，显示100％所需的最小OCV值为4242.6V
 
因此，如果您使用STC3115IQT（4.35V版本）测量4.2Vmax电池，则电量计可能永远不会达到100％。因此，在充电结束时您将无法获得正确的准确度。如果测量的SOC大于90％且测得的电压为4.2V（或者测得的电压为4.2V），您可以在软件驱动程序中添加一个变通方法，以手动强制REG_SOC为100％（或者接近它）。
问候

Hi,
The default OCV table is hardcoded in STC3115 (compared to STC3117 where the table is fully configurable by user). And the table values are different if you select the *IJT or *AIJT chip version.
The OCV curves in the following document show the min/max values possible for the OCV characteristic of your battery.

https://github.com/st-sw/STC3115GenericDriver/blob/master/Docs/Config/STC3115%20OCV%20curve%20-%20default%20register%20values.pdf
As long the the full OCV curve of the battery is located between the min and the max, you will get a good SOC accuracy from the gas gauge.
At page 3 of the document, you can see that for STC3115IQT the minimum OCV value required to display 100% is 4242.6V

So if you use STC3115IQT (4.35V version) to measure a 4.2Vmax battery, the fuel gauge may never reach the 100%. So you won't have a correct accuracy at the end of charge.You can add a workaround in the software driver to force manually the REG_SOC to 100% if the measured SOC is >90% and the measured Voltage is 4.2V (or close to it).
