I've noticed a lot (but not all) folks incorrectly referring to EVSEs as "chargers". For L1 and L2 J1772 AC charging, that's not correct. The charger is on-board the car. The L1 120 volt charging cable (or whatever GM calls it) is an EVSE. Whatever "charging station" (ok term to use) you install at home is or use commercially/in public w/a J1772 handle for L1 or L2 AC charging is also an EVSE.

I've told people over at MNL a bunch of times to get this straight to avoid confusion. See http://www.mynissanleaf.com/viewtopic.php?p=332668#p332668.

The diagram at http://www.mynissanleaf.com/viewtopic.php?p=262630#p262630 may help.

Perpetuating the wrong terminology can lead to confusion down the road, wasting money or buying the wrong vehicle, equipment or options/equipment level.

http://www.mynissanleaf.com/viewtopic.php?p=101293 under "Nissan LEAF Miles Gained per Hour Charging" has a table of Leaf charging rates. How quickly one can charge is influenced by many factors such as the max input/output of the on-board charger, max output of the EVSE, line voltage, etc.

The '11 and '12 Leafs only had a 3.3 kW on-board charger, just like the Spark EV. It could pull up to 16 amps @ 240 volts. The '13+ Leafs can have a 6 kW OBC (optional on S, standard on SV and SL trims) that can reduce 240 volt charging times by drawing up to ~27.5 to 30 amps at 208/240 volts. My '13 Leaf SV when charging on my work's 208 volt Chargepoint L2 EVSEs pulls about 5.8 or 5.9 kW, per the EVSE's display.

I've seen numerous '11 and '12 Leafs and Volts charging using those same EVSEs. They pull 3.x kW.

(http://www.myrav4ev.com/forum/viewtopic.php?f=2&t=67&sid=6ae9b8d03a5ba3f184577f68f8764543 under "Miles Gained per Hour Charging" has the Rav4 EV equivalent. It has a 10 kW OBC but you need a 40 amp EVSE @ 240 volts to take full advantage. I've seen Tesla Model S at work which also have a 10 kW or 20 kW OBC (depending on equipment level) pull low 6.x kW (6.1 or 6.2 kW, IIRC) from those same 208 volt EVSEs.))

Numerous other vehicles have 6+ kW on-board chargers such as the Ford Focus Electric, Coda (now dead), Honda Fit EV, etc.
