Chemistry selection in bq27541 BQEAsy for Panasonic NCR18650

I'm developing a pack with the Panasonic NCR18650 cell. Per Panasonic, it's Li-ion. the BQEasy description is NiCoMn/carbon. This does not sound correct. Can someone confirm the cell listing and chemistry are correct???

  • Yes, this chemistry ID and cell listing is correct. This ID was created specifically for this cell a while back. It is only listed is NiCoMn/carbon because that is the OCV curve it most closely resembled. It may not be exactly that chemical configuration, but it is nickel-based. Usually we don't get the specific chemistry of the cell, so an educated guess is sometimes required.
