But as Tony agreed,
There may be other factors, of course, like temperature and degradation (impedance), ...
The damage to the pack and the threshold
may be primarily a function of voltage.
But the observations on LEAF so far say there is more to the threshold
than voltage alone.
Will be interesting to see measurement of pack disconnect threshold
the 30 kWh pack uses.
And changes in that threshold with pack aging.
