48V Series Li-Ion Battery Module
The development and utilization of renewable energy are helpful to solve the current double crisis of energy and environment. It is one of the important technologies to promote the energy revolution and realize the sustainable development of energy. However, direct grid-connection of large-scale renewable distributed power sources poses new challenges to the stability of the power grid: on the one hand, the output power of intermittent new energy sources such as wind and light has volatility and randomness, and simple grid-connection will cause power impact to users; On the other hand, the access of distributed power supply has changed the pattern of one-way power flow in the power grid, making the operation mode of traditional power grid difficult to adapt to the new control requirements.
FnS 48V Li-ion Battery Module Series is a 48V deep cycle lithium iron phosphate (LiFePO4) battery and equipped with highly reliable and safe prismatic cells, build-in BMS, with intelligent communications and monitoring.
It is rack-mounted, light-weight and scalable for installation into standard 19″ rack or cabinet. FNS LiFePO4 48V battery is inherently safe and robust, and designed to have an extremely long life cycle due to the stable chemical composition.
Built-in Battery Management System (BMS) protects the cells against excessively high or low voltages, high currents, short circuits, and excessive heat or cold. Automatic cell balancing (by the BMS) reduces the charging rate in cells that have been topped off first, letting the rest of the cells to regulate voltage. This ensures that the cells are always balanced and ensures the quality and efficiency of the battery. The BMS is designed to gaurantee a long lifetime, safe handling, and high-accuracy State of Charge (SOC) calculations based on industry leading algorithms. Multiple batteries can be wired in parallel up to 15 units for increased capacity (no series wiring).
48V battery module has UL1973, UL1642, IEC62133, and UN38.3 certifications.
Communication port: RS232, RS485, Canbus, Modbus/SNMP/TACP.
