Safe 10-year energy storage for DC UPS systems
As DC UPS energy storage for longer hold-up times, lithium-ion technology with a high energy density is ideal. When selecting a safe Li-ion battery pack, a closer look at the used cathode material is recommended. With lithium-iron phosphate (LiFePO4), a very stable chemical compound with increased safety and a ten times higher cycle stability (6,000 charging and discharging cycles) compared to conventional Li-ion cells (LCO/NMC) is available. The high-quality LiFePO4 battery packs Bicker BP-LFP (heat shrink tube) and BP-LFP-D (DIN rail) also have a integrated high-performance battery management system (BMS) to optimize service life and security. The BMS monitors and controls the complete charge and discharge process of each energy storage battery cell. The integrated cell-balancing ensures a balanced and even charge of all cells, so that the full capacity of the lithium-ion battery pack remains permanently usable.
