So EV chargers are basically just gigantic surge protectors, yeah?

@cinebox Do they even protect against surge? DC fast chargers obviously have more electronics, but levels 1 and 2 seem to just be really fancy connectors for 110 and 220 VAC, respectively. In Europe I'm guessing it's either 220 and 440 or just a difference in currents.

@freakazoid I mean they have to do *something* to cost $300 a pop

@cinebox Mine has wifi and can do its own scheduling. It also tells me how much energy it added to the car, but I'm guessing it's just getting some kind of signal from the car rather than actually measuring.

@freakazoid yeah we just got one of those (the Juicebox) but even the standard OEM level 1 ones with nothing more than a few LEDs are several hundred dollars

@cinebox I didn't realize that. I just use the brick that came with my car for level 1. I have a ChargePoint hardwired level 2 charger I paid $350 or $400 for after the (at the time) Google employee rebate.

@kaniini @cinebox Level 2 requires a 40 amp 220 circuit in the US, which you can't get out of a regular wall outlet in Europe. Does that mean you can't charge from a wall socket in Europe? (Also, are there standalone level 1 chargers in the US? I figured it was just the charger that came with the car.)

@freakazoid in the UK you can do slow charging from 220-240V & 13A standard wall socket (around 3.1 kW) or you get a proper charger installed which ups the current to about 30A. it's not that weird cos we also have special circuits installed for, say, electric ovens

@obw Does the car charge at 13A? That would be much faster than what I was calling level 1 but less than half the speed of what I was calling level 2, which is the same as what you are talking about for fast charging. The charger that came with my car will work with 110/120 at 12A.

@freakazoid yeah the car pulls 3kW from the wall as far as I know.

@freakazoid @cinebox @kaniini In practice, level 2 is inclusive of everything above level 1 (that is, 100-120 VAC), so level 2 includes things like 240 V 13 A.

(Level 1 only exists in North America and Japan as a result.)
