Main Product >>Specification for Telecom LFP Battery System
 


I. Brief Introduction

  GYFP-T Series LFP Battery System is high-tech product, which is developed independently by HARBIN COSLIGHT POWER CO., LTD. It has outstanding advantages in certain occasions of telecom power supply field, such as clean energy, environment friendly, small in size, light in weight, long cycle life, good performance in high temperature, good power characteristic and etc.

II. Outstanding Advantages in Certain Occasions
   ■The advantages of small in size and light in weight are suit for small base station sites in large city.

  Take 48V 100AH LFP Battery System as the example:

Dimensions

540×220×365
mm(L×W×H)

550×440×270
mm(L×W×H)

LFP Battery is 65% of Lead-acid Battery in volume
Weight 70㎏ 148㎏ LFP Battery is less than 50% of Lead-acid Battery in weight

  Float charging Lifetime of LFP battery is more than 20 years for using in one or two class power supplying area under the intelligent management of BMS.
  ■ The advantage of long cycle life is suit for three or four class power supplying area.

  Seeing from the curve:
  In 25℃ LFP battery is 17 times of Lead-acid Battery in cycle life.
  In 45℃ LFP battery is 13 times of Lead-acid Battery in cycle life.
  While LFP battery is 5 times of Lead-acid Battery on cost.
  So LFP battery has high cost performance, and the annual average price is just 30% of Lead acid battery.

  This advantage especially apply to:
    ◆ Rely on the solar power and battery pack system without alternating current
    ◆ Rely on the DG and battery pack system without alternating current
    ◆The area where power failure occurs frequently with alternating current

III. Advanced BMS

  ■ Advanced BMS with overdischarge, overcharge, overcurrent and overheat protection to ensure well communication.
  ■ Charge and discharge protection, manage and equalize float charging.
  ■ Remote control to running status of system by GPRS.
  ■ The BMS can be compatible with existing high frequency switching power supply system.
  ■ LFP battery and existing Lead-acid Battery can be used together through management and control of BMS.

IV. Technical Parameters of 48V LFP Battery

Rated Voltage 48V
Charge Voltage 54V
Cut-off Discharge Voltage 42V
Charge Current ≤0.6C5
Discharge Current ≤0.6C5
Charge Temperature 3℃—50℃
Discharge Temperature -20℃—55℃
Storage Temperature -30℃—60℃

V. Recommended Application:

  ■ Scenario I: Replace the VRLA battery by lower capacity of LFP battery
  LFP battery can be charged rapidly, so it can adopt 0.6C5 to charge the battery. And there is no irreversible capacity attenuation.

  In Class III area,supposed that we change the existing VRLA battery to LFP battery in same capacity, although the annual average price is just 30% of Lead acid battery, while the one-time purchase cost is 5 times of Lead acid battery, which may be challenge for customers to accept.

  So we suggest that the customers can choose the LFP battery with 20%—30% capacity of lead-acid battery.

  For example:

  If the load current is 20A, 4 times power failure every day, and no more than 2 hours every time, you can choose 48V 100AH LFP battery and charge current can be limited between 40A—60A.
  If the load current is 30A, 4 times power failure every day, and no more than 2 hours every time, you can choose 48V 150AH LFP battery and charge current can be limited between 40A—60A.

  According to the scheme above, purchasing price of every time for LFP battery is similar with the one for lead-acid battery, but the using life of LFP battery is 1.5—2 times longer than that of lead-acid battery.

Comparison between Using Lead-acid Battery and Using LFP Batterywww.6175.comyl5566.com
  Existing lead-acid battery LFP Battery
Type 48V 600AH 48V 150AH
Cost About ¥21600 About ¥26800
Power supply mode

Three class power supply
4 times power failure every day
and no more than 2 hours every time

Three class power supply
4 times power failure every day and no more than 2 hours every time

Expected life time ≤2 years ≥4 years

  ■ Scenario II: Combine the LFP battery with existing lead-acid battery together
  ◆If the load is less than 1.5KW in Class III area, and there is already lead-acid battery in base station, if so, just add one set of 48V 100AH LFP battery. And Using the LFP battery with existing lead-acid battery together through the management of BMS can lengthen the service life of original VRLA battery. The LFP battery will charge and discharge preferentially when four grid outages in one day, and every time is less than 2 hours. While the VRLA battery will begin to work when every outage is more than 3 hours and the capacity of LFP battery is not enough to supply.
  So just add one set of 48V 100AH LFP battery with the cost of ¥20000. The service life of LFP battery is two times as long as that of VRLA battery, and can increase the service life of existing lead-acid battery more than one time. That is an excellent scheme.
  ◆If the load is less than 1.5KW in Class III area with frequent power failure, and there is already lead-acid battery and DG for power supply in base station, if so, just add one set of 48V 100AH LFP battery. And Using the LFP battery with existing lead-acid battery and DG through the management of BMS can not only lengthen the service life of original VRLA battery, but also reduce the starting times of DG and save the fuel, which will lengthened the service life of DG immensely.
  ◆ If the load is 3.0KW,48V 150AH LFP battery will be suitable.

VI. GYFP-T Series Telecom LFP Battery System

  Five series are available as below:
  ◆ GYFP-TC series: Cabinet battery system
  ◆ GYFP-TS series: Rack battery system
  ◆ GYFP-T series:(ETSI 19 inches rack)battery system
  ◆ GYFP-TX series:(ETSI 19 inches/Narrow Module)battery system
  ◆ GYDY-FP-T series: LFP battery integration power system

  As the newest generation of battery products, LFP battery will replace the lead-acid battery for telecom using with the outstanding advantages of clean energy, environment friendly, small in size, light in weight, long life and etc. We hope to carry forward these superiorities of LFP battery to better.
