Hi guys,
with this post i trying to hunt for informations about a strange problem of car batteries.
Is there any reason thinkable, that the first/last battery in an xs configuration gets an issue, given
- it is properly produced and balanced at factory status
- it gets charged and discharge for some (more) usage/cycles (supervised by the original BMS electronics)
and
- gets the issue, that repeatable the first and last Cell/pack proves to empty before the other Cells in a test. Not equal earlier, but earlier.
Any thinkable reasons for this ?
I have two assumptions, but i dont want to focus your thoughts.
No, i do not have more informations until now, but i may get answers to specific questions you might ask.
The question comes out of the car battery industry, from a person involved.
