So it's conventional wisdom that supercharging will degrade your battery life, and that, as a rule of thumb, the slower you charge, the better it is for the battery.
There must be a point of diminishing returns. For instance, is charging at 1kw going to be twice as good for your battery as charging at 2kw? I doubt it.
But, I haven't been able to find any credible sources that have done actual research on this. Is there anything that shows the difference in battery degradation on charging rates that are 11kw and below?
In my particular scenario, I'm wondering if I should avoid charging my M3 at 11kw (48 amps) if I'm charging overnight and could still get back to ~85% charge if I instead charged at 4 kw or 5kw. Or, if there is no difference, I might as well leave the charging system at 11kw at all times, and not bother "throttling down."
My electric company does not have time-of-use charging, so my only consideration is impact on battery life.
