While charging, the cells must not be exposed to temperatures below freezing point. If they are charged after all, dendrites could increase. Three or four charges during frost can already initiate such processes.
Batteries should not be installed in the boiler room or in the attic. Those places can become very warm in summer. Cool spots are to be preferred.
That is what the battery management system is there for. Overcharging causes the electrolyte to heat up. It vaporizes and the cell swells like a balloon.
At the Intersolar Europe 2019, SMA Solar Technology AG will be unveiling the new SMA Energy System, a package featuring perfectly coordinated photovoltaic, storage and digital energy solutions for private, commercial and industrial applications.
The storage and solar panel manufacturer Axitec Energy from Böblingen presents the Axistorage Li 10S for home and commercial applications.
If the cell voltage drops below a critical limit, copper particles come loose from the metal film at the anode. These will fall into the electrolyte, where only lithium ions should be.
Ingeteam is set to exhibit the company's very latest products and O&M services for the solar power and energy storage sectors.
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.
