In lumea bateriilor Li-Ion un ciclu reprezinta echivalenta de energie incarcata de 1C (C = capacitatea bateriei). 5 incarcari de 20% (sa zicem intre 30-50%) = 1 ciclu, ca idee.
Daca la leaf se raporteaza altfel e ceva fundamental gresit cu raportarea aia ... Edited by ro_explorer, 02 September 2023 - 12:11. |

@ro_explorer ai ceva date in acest sens 1C = 0-100%?
Intreb pentru ca eu prin OBD cu app car scanner daca pun 20-100% sau 30-80% imi contorizeaza 1C ceaa ce se pupa perfect cu ce zice @Adm, orice mufare se contorizeaza, separat am cantitatea de kwh totala incarcata cat si cea consumata. |

Informatia se gaseste peste tot unde se diseca in detaliu comportamentul bateriilor li-ion.
Un exemplu din lumea tesla: Quote Charge Cycles Charging and discharging a battery is known as a charge cycle. Charge cycles are a large contributor to the lifespan of a battery. It’s why many batteries are rated by the number of charge cycles they can support. One charge cycle is equivalent to using an amount of energy that is equal to 100% of the battery capacity. For example, if you charged a battery to 100% and discharged it down to 50% twice, then that would be equivalent to one charge cycle. Altul din lumea telefoanelor mobile: Quote You complete one charge cycle when you’ve used (discharged) an amount that equals 100 per cent of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75 per cent of your battery’s capacity one day, then recharge it fully overnight. If you use 25 per cent the next day, you will have discharged a total of 100 per cent, and the two days will add up to one charge cycle. De asemenea exista multe multe articole pe tema asta pe https://batteryuniversity.com/ La Tesla pot confima (prin datele citite din BMS cu "scan my tesla") contorizarea unui ciclu la acumularea unei incarcari/descarcari echivalente cu capacitatea totala nominala (NFP). Uite un snapshot relevant de la masina mea cand era bateria mai noua  ...

Una e raportarea statistica si alta e raportarea bob cu bob al unui ECU din masina, care incrementeaza +1 la fiecare conectare la AC/DC.
Acolo se da numarul de incarcari, nicidecum numarul de cicluri cf definitiei. |
