你好!
BQ40Z50-r1充电的过程中FCC和RM会跳动,由高变低,然后开始放电时又会变高?

您好,Typically FCC will jump when there's a big change in temperature, a big load or if internal resistance increases drastically.
The smoothing feature should be enabled to avoid FCC jumps.
Please share the configuration file and a full log to further investigate this behavior.
您好,您的GPCCHEM 报告推荐的是适合的CHEM ID,你FCC jump的问题已经在E2E英文论坛发帖,暂时没有收到回复,请继续关注。

你好,请问下这个跳动与这load mode的选择有没有关系,另外3=Averagr current 是实时的电流还是什么时候的,这个load mode 和load select要如何选择。
您好,请参考下面链接的内容
I took a look at the configuration file, it looks like they have load select set as 3 which is average current. With the load select settings that use the present information for simulation (AvgCurrent, Current, Present Avg Discharge Current, etc) they will use the saved "last run" parameter while in rest. If there is large deviation in the new discharge from the last the FCC/RemCap will be recalculated when the discharge starts with the new load. Also they should only be testing with a constant power discharge, do not do constant current discharging when load mode is selected as 1.
If this does not help please test with the most recent firmware, there has been many improvements to the smoothing algorithm since the -R1 release.
您好,Load mode and load select are defined in the TRM.

您好,current是事实电流,average current 是1分钟内的平均电流,所以拔掉充电器,AVERAGE CURRENT也不是马上变为0。
那么我之前fcc会跳的,Load Select选的是3。然后我Load Select选1就不跳了。我想问的是Load Select选项中1.2.3这几个电流有什么区别。。。
