I don't even have a charging station, I just plug that thing straight to the wall. I guess that's a level 1?

    When I plug it in, it says it's charging at 2.4KW, which I fuzzily convert to something like 7 or 8km per hour of charging. Note that this is on 220v on its own circuit.

    The circuit could fit a full fat charging station, but I haven't really gotten to it cause it works fine as is for my use.

    1.5 kw per hour, or 30kw overnight. That's about half charge of most battery packs.

    Sigh... I'm going to have to be a unit nazi.

    Power is the rate of energy transfer and is in kW. If 1kW flows for 1 hour it's 1 kWh (power x time). A US 120V socket at 12 Amps is just under 1.5kW. A 240V socket will be double that.

    1.5kW for 12 hours is 18kWh. That's not half a battery, as most cars start at 60kWh batteries now. 18kWh will get 54-72 miles depending on the consumption of the car.
