48V LFeLi Battery

48V LFeLi Battery

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 but Li+ can pass through it freely. The negative electrode which consists of graphite is shown in the figure on the right. Copper foil is the current collector of negative electrode. There is organic electrolyte in the cell which is sealed by Al-plastic composite film.

Parameter information subject to the contract, here for your reference only.

1.Lithium iron phosphate (LiFePO4)  is used as positive material, which offers extended cycle life and good safety performance.

2.Embedded BMS offers voltage, current, temperature protection and alarm functions. BMS can communnicate with other device by modbus protocol.

3.Embedded BMS unit measures current, voltage, single cell surface temperature and the ambient temperature of the battery.

4.Embedded BMS offers four remote functions which can communicate with far-end central control center by computer management.

5.The combination of BMS and computer management technology can achieve real-time monitoring and control of various parameters and status.

6.The power system has secondary cut-off protection and when the voltage is too low the system will cut off the support from the battery to protect the battery service life.

7.Under normal operating conditions, the entire system emits very little noise due to their passive cooling design.

8.Good electromagnetics shielding.
