STC3115 SOC值永远不会更新

嗨爵士/ Mdm,

关于STC3115我几乎没有问题。实施后,我注意到电压和电压。电流测量工作正常,但SOC值永远不会更新。
这是正常的吗?
2.在更新SOC值之前,STC3115是否需要经过最少次充电/放电循环?
3.是否有任何触发事件开始更新SOC值?
问候

Hi Sir/Mdm,

I have few questions regarding STC3115. After implementation, I have noticed that voltage & current measurements are working properly, however the SOC value is never updated.
1. Is it normal?
2. Does the STC3115 need to go through a minimum number of charge/discharge cycles before it can update the SOC value?
3. Is there any triggering events to start updating the SOC value?

你好,
 
请看下面的答案:
 
这是正常的吗?
不,这不是正常行为。
SOC是来自燃油表的最重要的预期信息。
 
2.在更新SOC值之前,STC3115是否需要经过最少次充电/放电循环?
不,第一个SOC在2秒后可用。
 
3.是否有任何触发事件开始更新SOC值?
不会。但是,当燃气表未正常运行时,通常会出现此问题。
这可能是因为引脚BATD浮动,避免了电量计启动电池监控。
 
解决硬件问题后,建议使用ST开源驱动程序正确初始化设备并运行它。

它类似于STC3117。

Hello,

Please see answers below:

1. Is it normal?  
No, this is not the normal behavior.  
The SOC is the most important expected information from a fuel gauge.

2. Does the STC3115 need to go through a minimum number of charge/discharge cycles before it can update the SOC value?  
No, the first SOC is available after 2s.

3. Is there any triggering events to start updating the SOC value?  
No. But this issue usually arise when the gas gauge is not running properly.  
It could be because the pin BATD is floating, avoiding the gas gauge to start the battery monitoring.

Once the hardware issue is resolved, it is then recommended to use ST open source driver to initialize properly the device and run it.

You can find a FAQ of common STC3115 questions/issue from the community here:

It is similar for STC3117.
