Storage advice: The safety restrictions are the job of the BMS

5/16/18, 5:00 PM -

The safety system in the battery management system (BMS) has to be able to determine irreversible damage to the cell. And it continuously monitors the cells.

A solar battery needs a monitoring system.

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:
