Standard Charge\Discharge For Lithium ion Battery For Solar Storage

1 / Standard Charge :

  Test procedure and its criteria are referred as follows:

   Charging shall consist of charging at a 0.2C5A constant current rate until the cell reaches54.75V. The cell shall then be charged at constant voltage of 54.75volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.01 C5A . Charge time : Approx 6h, The cell shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.

2 / Standard Discharge:

Cells shall be discharged at a constant current of 0.2C5A to 37.5volts @ 20º ± 5C

If no otherwise specified, the rest time between Chare and Discharge amount to 30min.

      

  Performance :


  1. Environmental friendly: ROHS passed
  2. High density of energy : bigger capacity 
  3. Light weight
  4. Low self-discharge
  5. Low internal resistance
  6. Long cycle life, chargeable up to 500 times
  7. No memory effect
  8. Doesn’t contain Mercury, No fire, No explosion, No leakage
