I use BQ2014 in our product. I have a issue. the LMD was correctly updated to 244 when discharing. But the LMD may change to other value suach as 184 or 224 during charging. Would you please teach me anything is wrong?

Hi Zeng,
I think the LMD can update to the DCR value at the end of charge as well, so if you are charging under a different temperature condition, especially a lower temperature, you could see the LMD change to a smaller value at the end of charge then at the end of discharge.
