This is the practical limit of operation without reduced performance.
My spidey-sense tingles at that. Maybe non-plug hybrid designers really don't care about battery capacity (though that woiuld surprise me). However, for true EVs, we definitely care about usable capacity. Where I come from, we normally define battery EOL as when capacity falls below 80% of specification. Any time a researcher (or a "researcher") redefines a key performance measurement, I immediately suspect that either he's talking about something that doesn't apply to me, or that he's attempting to reach a desired, pre- defined conclusion. Show me why neither is the case here.
