48V 100AH 19”Standard Cabinet Telecom Lithium Ion (LiFePO 4 ) Battery Pack 482.0mm X D 540.0mm X H133.0mm

• Product Overview

The 48V Lithium Ion Battery Pack is mainly working as 48VDC backup power source, and it consists of 15 cells of Lithium Iron Phosphate Battery Cells connected in series and telecom specialized high performance and high reliability Battery Management System (BMS). The battery’s +/- output terminals are connected to the +/- terminals of rectifier. When the mains supply is normal, telecom equipment is powered by mains through rectifier and battery pack is also charged through rectifier; When the mains supply is outage, the 48V lithium ion battery pack is supplying power to telecom equipment without any time-delay to ensure telecom equipment is powered without any interruptions, until mains supply resumed or protective power cut-off by BMS due to over-discharge protection activated automatically.​

• Features and Benefits​

• Host computer control function

1) Through the host computer to set the protection parameters such as overvoltage, undervoltage, overcurrent, overtemperature, under temperature, short circuit, as well as balance, sleep, capacity, and other functional parameters and various alarm parameters.

2) Supporting monitoring of battery pack related information, battery status information, etc.

3) Supporting storing and exporting related data

4) Supporting writing barcode

5) Remote Control and Telemetering

• Serial port upgrade function

The management system can be upgraded via the RS485 interface.

Communication Protocols

Default setting protocol with baud rate 9600, and other protocols are also supported.

• Charge current limiting function

After the current limiting module is assembled and enabled by the host computer, the charging current limiting function can be implemented. The current limiting mode is current limiting after charging and overcurrent; the current limiting value is 10 ± 1A.

• Anti-reverse function

Battery has Anti-reverse circuit. After the system is powered on, the protection board will be burnt due to the reverse connection of the battery during parallel installation.

• Parallel communication function

The parallel communication function can be realized through the RS485 interface, and it can support up to 6-digit DIP switches (typically 4-digit DIP switches) for setting addresses when communicating in parallel. After parallel connection, the battery pack data can be monitored cyclically through the parallel version of the host computer.

• Data Storage

Battery supports no less than 500 battery status data storage functions, protects all data and regular historical data during all state transitions, and stores 1 historical data every hour.
