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. permalink fedilink source parent [–] Cort@lemmy.world 1 point 5 months ago I level 1 charge and get 20 miles in 7 hours. So the average 40mi commute should be possible overnight. permalink fedilink source parent [–] SaveTheTuaHawk@lemmy.ca 1 point 5 months ago (2 children) 1.5 kw per hour, or 30kw overnight. That's about half charge of most battery packs. permalink fedilink source parent hideshow 2 child comments replies: [–] wewbull@feddit.uk 3 points 5 months ago* 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. permalink fedilink source parent [–] Hule@lemmy.world 3 points 5 months ago That's some Alaska winter night with 20 hours! permalink fedilink source parent
