38V 100AH 19”Standard Cabinet Suited Rechargeable Lithium Ion (LiFePO 4 ) Battery Pack
The 38V Lithium Ion Battery Pack is mainly working as 38VDC backup power source, and it consists
of 12 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 38V 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.
- Voltage detection and protection function
The Product has the functions of cell and module voltage detection, over voltage, under voltage alarm
and protection. The cell voltage detection accuracy is less than ± 15mV under normal temperature static
conditions.
- 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.
- Temperature detection and protection function
With the function of cell and environment temperature detection, when the temperature is too high or too
low the product will start up alarming and protection function. The temperature sampling accuracy is less
than ±2°C within the operating temperature range. Four battery temperature detection points and one
ambient temperature detection point (maximum 16 battery temperature detection points) are supported
by default.
- Short-circuit protection function
With short-circuit protection function, the short circuit delay time can be set by the host computer. The
short circuit current should be less than 1200A.
- 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%
