    DC fast charging typically runs at 400 volts, with some cars doing 800. They also do it with highly specialized equipment and service lines you’d never see in a residential setting.

    When charging at home, you have all night. A 50A circuit will go 0-100 on most cars in that time, and if you look at what most people actually drive you can generally get by on much less.

        how much amperage does utilities allow for residential use ? imagine charging ur car at 50 amp and decide to turn the heater on, only to trigger the breaker and cause the house to go dark lol

        A fair question. Depends on the house. 100-200 is common, depending on the age of the house. 100 or less if your house predates central air conditioning, and 150-200 is far more common in the last few decades. Most people charge overnight, and they’re not using much else. If you truly have a smaller connection, even 20A @240V is surprisingly useful. Or hell, a normal outlet.

        80kwh each night, wth ?

        That may be your battery’s capacity, but that’s not necessarily your draw. How big is your gas tank? Do you give it ~15 gallons each day? My car gets about 3.5 miles per kWh. If I drive it 70 miles, that’s 20 kWH and then the car stops charging. And I pay about $2.50 for it. What would gas cost?

        u probably need 75m² of solar to generate electricity for 5 hours, generating 75kwh, enough to fully charge ur car for free, but also u need 7*11kwh powerpacks to accomodate all this energy. seems costly as hell.

        Solar direct to car is actually a terrible idea. Just hook something up to the grid if you want solar, but it’s pretty cheap without. You’re overthinking it, probably because your 80 kWH per day number is so out of whack.

        unless also ur job offers supercharger parking, which would be more suitable

        Again, no. Well, it’s cool if you can get it but it’s really not needed because home electricity is generally way cheaper than gasoline.
