To estimate the number of cycles that the cell can undergo in its lifetime, we charge it at a maximal current of 0,5C and discharge at a current of 1C at 25 degrees Celsius and then we count the number of charge/discharge cycles until the cell degrades down to 70% of its initial capacity (2250mAh). In the case of these cells, the number is about 500 cycles.Durch die neue Möglichkeit, den Ladevorgang überwachen und jederzeit beenden zu können, kann ich eine Einstellung wählen, die den Ladevorgang bei, sagen wir 95%, abbricht und somit die Haltbarkeit des Akkus drastisch erhöhen ^^
500 cycles? But that’s (relatively) low! Yes. But what is not shown on the spec sheet is that when you partially charge and discharge, degradation of the battery capacity is reduced. Thus, you can do over 40 000 charge/discharge cycles when going from 30% to 70% only. Or over 35 000 charge/discharge cycles from 20% to 80%; 28 000 cycles from 10% to 90%; 15 000 cycles from 8% to 92%, 7500 cylces from 6% to 94%, and the capacity reduction goes faster and faster, finally reaching 500 cycles when recharging from 0% to 100%.
This explains the partial cycling strategies implemented by car manufacturers: GM limits the cycle from 17% to 80% of energy storage levels for the Volt. Nissan limits maximum charge level of the LEAF to 90% (4,15V). Tesla invites owners to limit the maximum load to 90%, and recommends avoiding deep depletion of the battery pack. All these strategies work well and significantly increase the number of battery cycles. When I manage the power levels of my own Tesla, I try to keep my maximum load below 90% and avoid depleting below 20%. Following this practice since the purchase of my Tesla, I have seen no capacity degradation. My wife’s 2012 Volt shows no degradation either. In fact, no Volt has yet shown degradation below 70% of the initial capacity which would have resulted in a warranty claim. In conclusion, we can trust the reliability of our Lithium batteries!
