Specification

• LED fuel Gauge
  
  • There are 5 micro-LEDs installed on PCM.
  • On/off Switch - to check estimate battery capacity status. ( approx 15% per each LED light )
• Interface with PC.
  • BQ20Z95DBTRG4 IC (click underlined to download IC specs) is installed on PCM for communication with PC or LCD display card (optional item)
  • Connector adapter: 2' long Convert from 4 Pin Female JST plug to 4 pin Female Molex Connector (not included) for connecting PCM to PC interface
    • To communicate with PC, you must order this Interface hardware from Texas Instrument, EV2300 Evaluation Module Interface Board for SBS, (Please click underline to order)

      •  Please click here to download user manual EV2300 Evaluation Module Interface Board 
      •  Please click here to download user manual of bq evaluation software
  • From PC, you can collect battery pack running data as follow:
    • Voltage
    • RemCap (mAh)  --> Remain Capacity
    • DnCap (mAh)  --> Design Capacity
    • FullCap (mAh) --> Full Capacity
    • Temp ('C)
    • Current (mAh)
    • Cycle (CYC)
  • You can check each cell's voltage as  follow:
    • Cell -V1 (mV)
    • Cell-V2 (mV)
    • Cell-V3 (mV)
    • Cell-V4 (mV)
    • AveTTE (min)
    • AVETTF (min)
    • SN

Other components required to operate the SBS (Not Included )  

• LCD Display (Please click here to buy separately)
  • This LCD display will show all data available for you without the use of PC.  
  • LCD display 1 (Push "On/Off" Switch 5 milli-sec) 
  • LCD display 2 (Push "PU/PD" Switch)
  • Note: You may push ""On/Off" Switch" for switch back to LCD display 1   
• Charger
  • You must choose a smart charger based on battery pack type and voltage.
  • Ex: for a 2 cells Li-Ion battery pack, you will need a 7.4V smart charger with 8.4V CCCV cut-off
  • Ex: for a 3 cells Li-Ion battery pack, you will need a 11.1V smart charger with 12.6V CCCV cut-off
  • Ex: for a 4 cells Li-Ion battery pack, you will need a 14.8V smart charger with 16.8V CCCV cut-off
• DIY connector
  • Charge / Discharge terminal connector
