I've never actually experienced this. I believe the 320 amp / 320 volt charging is for emptier cars... I've plugged in at a 100% full charger and gotten full power charging.

As you know, the fuller your battery gets, the less current it draws.

If your neighbor was already at the end of their charge cycle, then they will be drawing relatively little, and you'll get the full current.
