Designed for compliance with IEC61427, IEC60896-21/-22, etc Discharge & Charge Scenario (80%DOD)
1) Cycle method:Discharge with 2I10for 4 hours (80% DOD), charge with 2I10for 3.5hour + I10for 0.5hour + 0.25I10for 3.5hour. This is one cycle.
2) Residue Capacity determination: The batteries are discharged at 10 hour rate after every 50 cycles to test battery capacity. When residue capacity of 10 hour rate capacity is lower than 80%, test is ended.
After discharge at 10 hour rate after every 50 cycles, the charge method is: charge 80% of discharged capacity with current of 2I10+ charge 20% with current of I10+ charge 20% with current of 0.4I10(i.e. charge 120% of discharged capacity)
3) Temperature: 25â„?br>1.3  Advantage of Upper Constant Current Charge Model
Battery can be completely recharged within 8 hours.
The end charge voltage will be higher than 2.6Vpc, which is good for active material exchange.
1.4  Disadvantage of Upper Constant Current Charge Model
It has risk of battery malfunction without voltage limited.
It isn’t easy to manage charging in practice.
