3. Can too much AMPs destroy anything or should the charger be able to control that?
4. Is a DC Quick charge something that could be installed in a home? Not needed, but just curious because I can't find much on it.
The outlet is going to be installed about a foot away from the breaker, so I figured I should future proof this since it shouldn't be much of a difference in cost, but let me know what you think. The house is newer and built last year. Images below
Thanks in advance!
3. You need to understand the physics of it: an electric device draws as many amperes as its designed to use. Think of a long jump athlete: he jumps as much as he can and making a bigger sand pit will not make the athlete jump further. On the other hand if the pit is too small he will land on hard ground and break his ankle.
So if your charger draws 27 amps, installing a smaller breaker will cause it to trip. If the braker is bigger nothing will happen.
EXCEPT: if you install a 50A breaker and something goes wrong with your device designed for 27A the breaker will not protect it and you may damage your device or even cause a fire. Remember that all wires INSIDE the charger are sized to 30A.
it is always a good idea to design the circuit EXACTLY for what it will do. My circuit uses 40A wire to comply with code but I installed 30A breaker such that it trips faster if the current exceeds 27A.
If your charger is so close to the breaker panel upgrading to a 50 A circuit will not be an issue in the future. i would advise against installing this charger on a 50A breaker.
4. DC charging is nearly impossible to install in a regular home due to the large power requirement. To supply 50 kW you need a 200A circuit at 240V which is all that your service can provide meaning that you cannot use anything in the house while charging. No inspector would allow you to do this. It is prohibitive in price (40K$) and you should not QC your leaf on a regular basis. So don't even think of it.
