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.
China-based BYD now expands the low-voltage battery storage portfolio with the latest generation of the Battery Box LV.
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.
The Tesvolt high-voltage storage system has been shortlisted for the ees AWARD. The winners will be announced June 20 in Munich.
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.
Hoppecke’s large hybrid storage system has been given a new name that precisely describes its advantages.
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.
