Temperature of 45℃ and charge /Discharge rate of 1 C
There is a trend of 2% drop in retention for every 50 cycles after first 50 cycles. Estimated that there is totally 20% drop in retention after 500 cycles, which means retention is 80%. So that is the cycle life. This is continuously charging and discharging test in the lab(non-stop, no cooling for battery).
When it is charging and discharging with 8-12 hrs. which is halved of non-stop use and with on and off some idle time, We estimated cycle life will be about 750 cycle life.
Temperature of 45℃ and charge /Discharge rate of 0.5C
Estimated there is 1% drop in retention for every 50 cycles after first 50 cycles as discharging rate halved, and that there is totally 20% drop in retention after 1000 cycles, which means retention is 80%. So that is the cycle life. This is continuously charging and discharging test in the lab( non-stop, no cooling for battery).
When it is charging and discharging with 8-12 hrs which is halved of non-stop use and with on and off some idle time, We estimated cycle life will be up to 1500 cycle life.
Temperature of 60℃ and charge /Discharge rate of 1C
The retention rate already hit 80% level from the lab test, which is the cycle life of max 200 cycles by definition. This is continuously charging and discharging test in the lab( non-stop, no cooling for battery).
When it is charging and discharging with 8-12 hrs which is halved of non-stop use and with on and off some idle time, we estimated cycle life will be up to 300-350 cycle life. At this such high temperature, cycle life may improve but limited.
Temperature of 60℃ and charge /Discharge rate of 0.5C
Estimated it hits 80% level at 300 cycles although discharging rate halved but temperature is high. This is continuously charging and discharging test in the lab( non-stop, no cooling for battery).
When it is charging and discharging with 8-12 hrs which is halved of non-stop use and with on and off some idle time, we estimated cycle life will be up to 400-450 cycle life. At this such high temperature, cycle life may improve but limited.
