160 amps alone is more than standard house connect. In any case you will likely be charging overnight, and then given the time available pumping 80 amps into your precious depreciating battery is a great way to make it lose lots of value, quick. What people need in their garage is 20 amps for the trickle charge to replenish the 30 miles lost from their commute and some grocery shopping overnight.

It's likely a 100% EV home would want the option to charge as quickly as possible, even if they trickle charge most of the time for the sake of battery life. It's also likely that future EVs won't have this battery limitation, just put in the heavier gauge wires and breakers while you're in there if the house is going to be around for the next century.

You are right, but you forget about emergencies. Hospital is 10km away, and batteries are empty. Do you want to wait 2m for enough juice, or 10m? Or less gloomy: In between appointments, you drive home to charge. Do you want to come 15m late just because your pipe is too weak? Big pipe = freedom.

  In an emergency, you surely call an ambulance, not drive yourself.

    Not really. Where I am that'd take at least double the time. Depends on what kind of emergency it is, of course, I'd not move someone with spinal injury, but if my girlfriend is feeling terribly sick, I'd rather drive her (that's an actual real life example that happened to me).

    Depending on your insurance, ambulance and emergency charges can be either rather high copay or only % covered, and are NEVER cheap on their face. My wife drove me to the emergency room on a 3am Sunday morning when I felt like someone was pushing a golf ball out through my ribs and I had my gall bladder out that week. $750 copay for ambulance service.

      I am aware that the ambulance is not free in the US, but it's quite hard to comprehend I guess. Especially in an emergency, I wouldn't think of anything other than calling one, driving to hospital myself wouldn't even cross my mind.

      Yes, but you're talking about a maybe once in a lifetime event here (need to rush to the hospital, but you just got home with your EV on 1% battery). Just eat the ambulance bill and curse your bad luck.

  This scenario seems contrived to me. You'd have to have an emergency immediately upon the termination of a trip during which you'd completely exhausted your battery. You can run out of gas in an ICE car too, and then it's even worse because you need to go track down a gas can instead of plugging in. The simple solution, of course, is to never fly that close to the Sun.

    With a gasoline car, you can in most cases drive to the next gas station, and get enough fuel to get to the hospital within 1-2m. With an EV, you have to wait. Did I overlook something? The scenario of an empty EV battery is not that unlikely. Eg you forgot to charge when you returned.
