I am interested in the reason why stopping "brutally" a charge could damage something.
...
I can't speak for BTR, but one issue is arcing. EV plugs all have shorter pins for
signalling, so that the station can stop power flow before the expensive silver-coated
high-current contacts pull apart. If you are in the habit of unplugging a household
cable under load, you can probably see the effects of arcing on the plug. This can
cause increased resistance, let's call it R, and then power becomes heat at P=I^2R
current squared time resistance, which can, as R increases, melt outlet or worse.
