New tile Lastmanagement-Details -> Batterie-Vermessung. From the 15 minute slots evcc stores per battery (energy charged and discharged, soc at the slot start) of the last 60 days, charging and discharging runs over at least 20 % soc give the energy per 100 % soc each way; the medians of at least 3 runs each give capacity = sqrt(kc * kd) and round trip efficiency = kd / kc. Runs with a soc jump, a gap or flow the other way are left out, an hour idle ends a run. Refreshed every 6 hours, plausible at 50-120 % of the configured capacity and 60-100 % round trip. "Gemessene Werte verwenden" (off by default) puts the measured capacity into the optimizer request (stored energies scaled, soc values unchanged) and lets one-time grid charging plan with the measured capacity and charging efficiency. The optimizer's efficiency is shared with the vehicles and stays. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Die Batterie lernt ihre nutzbare Kapazität und ihren Wirkungsgrad aus den Daten, die evcc ohnehin je Viertelstunde speichert, statt mit dem Datenblatt zu rechnen. Neue Kachel Lastmanagement-Details → Batterie-Vermessung, standardmäßig nur Anzeige.
