There are some mistakes. Also, I only have personal experience w/viewing power levels by charging these vehicles via the 208 volt (common commercial voltage in the US) L2 Chargepoint 30 amp EVSEs at my work and the graphs I can see via their web site (example at http://www.mynissanleaf.com/viewtopic.php?p=490435#p490435) and mobile app. I sometimes plug in cars for other folks at work.
http://carcharging.us/ev/leaf.php amperages are wrong. '11 and '12 Leaf had "3.3 kW" OBCs. IIRC, they can draw ~3.8 kW from the wall at max at 208 or 240 volts. I've pluged in '11 and '12 Leafs on the above EVSEs and they tend to pull ~3.8 kW from the wall, even at 208 volts.
13 amps isn't right. 13 amp * 240 volts = 3,120 watts = 3.12 kW
28 amps may not be right either... '13+ Leafs can come with 6.6 kW OBC. Specs tab of http://nissannews.com/en-US/nissan/usa/presskits/us-2013-nissan-leaf-press-kit says "6.6 kW onboard charger (6.0 kW output)". I've seen graphs posted here on MNL (one went away and isn't on archive.org either) showing one pulling 6.6 kW from the wall. Since my work's voltage is only ~208 volts, I've seen it draw usually 5.9 to 6.0 kW. It can range actually from 5.7 to 6.2 kW depending on where and other unknown factors (possibly voltage drops in some places as well as variances in input voltage). 6000 watts / 208 volts = 28.84 amps.
It is also incorrect to state "Earlier models had a slower 13A/240V internal charger." '13 to '17 S trim w/o charge package (see specs tab of http://nissannews.com/en-US/nissan/usa/presskits/us-2017-nissan-leaf-press-kit) come with 3.x kw OBC ("3.6 kW onboard charger (3.3 kW output)").
http://carcharging.us/ev/prius.php should distinguish between the 2012 to 2015 Plug-in Prius and Prius Prime, which I believe began w/2017 model year. 2012 to 2015 PiPs @ 208 volts seem to draw only ~2.1 kW. Prius Primes seem to draw about ~3.x kW. http://www.greencarreports.com/news/1103052_2016-toyota-prius-prime-details-on-120-mpge-plug-in-hybrid-all-electric-mode seem to confirm this
The outgoing Prius Plug-In came with an onboard charger rated at just 2.2 kW. To keep up with the demands of charging the larger pack, in about the same time as the previous one, Toyota has at last upgraded to a 3.3-kW one,
Will need to see if I have graphs from a charging a Prius Prime.
http://carcharging.us/ev/volt.php - Gen 2 Volt has a slightly higher wattage OBC at 3.6 kW instead of 3.3 kW. I recall that gen 1 Volts I plug in at work tend to pull ~3.1 kW or so. Gen 2 I believe do end up pulling ~3.3 kW. I need to see if I have graphs from this.
