Rack mounted Embedded BMS 48V LFeLi Battery Lithium iron Phosphate battery (LiFePO4) for FTTH,FTTX

Lithium iron Phosphate battery (LiFePO4) has a nominal voltage of 48VDC. It is comprised by 16 cells of 3.2V each. The internal structure of LiFePO4 battery cell is shown in the figure on the right. Shown is the olivine structure of LiFePO4 as the positive electrode of cell. Aluminum foil functions as current collector of positive pole. A polymer membrane separates positive and negative electrodes of the cell. The electron (e-) can’t pass through the polymer separator


1. The cathode material is Lithium Iron (LiFePO4), which has long cycle life and good safety performance.

2. Integrated BMS provides voltage, current, temperature protection and alarm functions. BMS can communicate with other devices through modbus protocol.

3. Combine the current, voltage, individual surface temperature and ambient temperature of the BMS unit cell.

4. The embedded BMS provides a variety of remote functions, which can communicate with the remote central control center through computer management.

5. The combination of BMS and computer management technology can realize real-time monitoring of various parameters and states.

6. Protection of the power system, when the battery is too low, the system will provide support for the battery to protect the voltage from being too low.

7. Under normal operating conditions, the noise emitted is very small due to the direct cooling design of the system.

8. Good electromagnetic shielding.
