Other Parts Discussed in Thread: GPCRB, GPCCHEM
客户反馈低温-30℃进行300mA放电时,SOC一直显示100%,经过复测,发现剩余及满电容量,突变到0,SOC一直显示100%,阻抗表也没出现紊乱,正常数值。
该5s10Ah的锂电池组为批产项目,进行过CHEM ID,Golden learning,更新过Ra table,形成了批量生产文件。
下图是出现故障时各寄存器状态,以及阻抗表信息,.csv文件为保存的数据。

您好,您是否用GPCRB tool (https://www.ti.com/tool/GPCRB) 完善低温的参数。
-30℃ 300mA 放电, 跳变到0是发生在放电前还是放电的过程中,电池放电了多长时间,您提供的是放电以后的数据吗?
您好,建议用GPCRB tool (https://www.ti.com/tool/GPCRB) 完善低温的参数
您好,Please try using the gpcchem tool to determine the chemID (to see if the value changes). Then, program the chemID result on top of your gauge with the settings for your application. Please do not learn the pack after this step. Then, export the gg.csv file and use this new gg.csv file with your upload.
If the issue still persists after these steps, please send the error again as you have done above.
您好
Temp A/Temp K are the parameters used to estimate the self heating of the battery under load. They are learned by the gauge so you should not need to modify them.
They are also an output of the GPC tools if you want to lock them to a specific value.
