Storage advice: The safety restrictions are the job of the BMS
That means: each cell, at least as far as temperature and electrical operating values are concerned. This hints at changes in the electrolyte or at the dreaded dendrites.
Operate in accordance with a derating curve
To eliminate such risks, the charging electronics of the battery need to operate according to a derating curve. This adapts the charging currents to the cell temperature in order to regulate them at too low or too high temperatures as well as at the voltage limits. (HS)
Look at this, too:
