isn't supposed to be super high voltage to work ? or maybe this would be super slow ?
There are 3 charging levels. 1 is basically just "plug your car into a wall outlet". 2 is more powerful, and usually involves installing a little charging box with a cable, but it's still AC and fairly slow. 3 is the DC fast charging that operates at crazy high voltages and currents.
In much of the world the wall plug is the bottom end of level 2.
Is level 2 solely defined by "240V AC"? I wasn't sure, although the portable chargers some brands have in the US with 240V attachments are still level 1 I think.
I believe the two requirements for level 2 are 200 VAC and 2 kW. A 208V 30A oven outlet in a typical American apartment is level 2, but so is a 240V, 15 A plug in a typical European, well, any room.
The 240V, 30A+ portable EVSEs many cars come with are level 2, though they are often also able to do level 1 charging if they work on 120V outlets.
yo I have no idea what this conversation is even saying anymore, I don't speak electron ๐ฅ๐ฅ๐ฏ
that's a first-gen chevy volt from 2012-2013. it can't fast-charge at all, it's limited to line voltage only. a full charge takes five hours, give or take. thankfully it's a hybrid.
Most EVs can charge off kf a regular socket using a dedicated cable.
It can take days to charge.
Can confirm. Mine will take about 3 days to charge from very low to full on a regular wall outlet. Still worth it sometimes though, like when I'm visiting family or camping or something. If I'm gonna spend the day somewhere (like 6+ hours, let's say) it might be worth it.
The car can take 120/240 V AC input. Internally, there's a AC to DC rectifier that brings the voltage up to the internal battery's voltage. For 120V 15A charging, this is pretty slow in general since EV batteries have a large capacity.
I changed off a 12v 20amp outlet for over a year at my house till the charger was installed. It would take 12 hours to charge from empty to full but never had that happen except going on trips, then I would use the DC charging stations.
You have a 12V outlet? Why not use 120V or 220V that everyone has?
