The new Li-Ion battery pack BP-LIO-1525 from Bicker Elektronik reportedly offers five times more charge/discharge cycles than conventional lead-acid batteries and thus brings a particularly long service life. The high-quality battery pack impresses both in industrial use and in medical technology applications with its approvals according to IEC/EN 62133-2:2017 and UL 62133:2017 Ed.2.

The BP-LIO-1525 has an integrated BMS (Battery Management System) to optimise service life and safety. The BMS monitors and controls the entire charging and discharging process for each battery cell in the energy storage system. The NTC temperature sensor, which is led outside, enables permanent monitoring of the Li-Ion cell temperature for charging optimisation and operational safety.

What are the advantages of lithium-ion technology compared to lead-acid batteries? In terms of system integration and economy (TCO), Lithium-Ion cells enable energy storage devices with space and weight savings of up to 75% – compared to conventional lead-acid batteries.

Lithium is the lightest metal in the periodic table and has ideal electrochemical properties for providing high specific energy densities (Wh/kg). Also many times higher than with lead-acid batteries is the number of charging cycles and the realisable Depth of Discharge (DoD). Finally the service life under comparable operating conditions is up to five times longer.

'System-Present' function increases safety

With the help of the system present function, the output of the battery pack remains deactivated (output voltage = 0V) until the main current path is released by bridging the communication plug. Otherwise the BMS locks the MOSFET main switch permanently. Since the components on the BMS board run in standby mode, this power-saving function also increases the shelf life of the (charged) BP-LIO-1525.

'Cell Balancing' for consistently high performance

The integrated cell balancing ensures a balanced and uniform charge of all cells, so that the full capacity of the lithium-ion battery pack remains permanently usable. This has a particularly positive effect on the service life, number of cycles and capacity of the energy storage.
