Lithium Ion Telecom Battery 48V 50AH 19' Standard Cabinet  High Capacity

48V 50AH 19”Standard Cabinet Telecom Lithium Ion (LiFePO 4 ) Battery Pack 440.0mm X D 390.0mm X H132.0mm

• 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​

• Current detection and protection function

The Product has the functions of charge and discharge current detection, alarming and protection. The charging current is shown as a positive current and the discharge current is shown as a negative current. The current sampling accuracy is less than ± 2% under normal temperature conditions.

• Communication function

It can communicate with the computer or host through RS485, upload and save the collected information.

Supporting CAN bus communication (optional).

Supporting2G/3G/4Gcommunication (optional).

Supporting Bluetooth communication (optional).

• Battery capacity calculation function

Cell algorithm: About the use of soc and soh, soc uses the basic elements of the Ampere integration and OCV method. The Ampere integration method and voltage, by the adjustment of the algorithm, with higher precision data and Independent clock system, ensures reasonable display during a single cycle. And the SOC estimation accuracy is ≤ ± 8%.

• Balance function

When the battery pack is charged, if the cell voltage reaches the equalization turn-on voltage, and the maximum voltage difference is greater than the equalization voltage difference, the cell that meets the condition turns on the equalization function. Battery supports up to 6 channels simultaneously to turn on equalization. The maximum equalization current is about 75mA.

• LED indication function

6 LED indicators are used to indicate the battery’s status. 4 green indicators are used for showing battery SOC, 1 red indicator is used for showing failure indication, 1 green operating indicator is used for showing battery’s operation status, i.e. standby, charging, discharging, etc.
