Are you trolling for indignant responses?


Not at all. I'm still new to the whole EV thing and trying to find definitions for all the terms is a bit harder than I think it should be. It doesn't help that the average customer seems to know more about the various systems than the average car dealer/seller. And of course, the average MNL forum user is probably more knowledgeable yet but still....from reading all the various posts here since I bought my Leaf (which has been my main education in the topic) I came to some erroneous conclusions about the what some of the various terms actually mean.

And as an entirely OT aside, it would sure be nice if there was a FAQ section somewhere that explained the differences between EVSE and 'charger', L1/L2/L3, DCQC, Chademo, kW and kWh, SOC and SOH, etc, etc. There is a lot to learn for a new EV owner and reading through years of posts is not an efficient way to educate oneself. For example, I've been reading MNL since I bought my Leaf 8 months ago and never once encountered a post indicating the precise definition of L1/L2/L3 charging. I made some bad assumptions and then repeated them and I'm sure I'm not the only one in that boat.

We'd love to have a FAQ, but the site owners seem to have zero interest in doing anything like that. We can't even make a "sticky post" that will remain in sight.

I'll take a stab at a couple of those questions:
EVSE is what plugs into the wall(or can be hard-wired) and then plugs into the car(for L1 and L2).
The charger is whats in the car and converts this AC power to DC to charge the battery, with L3 or QC the box that plugs into the car bypasses the internal charger and supplies DC power directly to the batteries, therefore could and usually is called a charger.
Chademo is the standard of QC the Leaf uses, other mfgs. may use CSS?? They are incompatible, a car with QC would use either one or the other.
Kw is 1000 watts(a typical hair dryer or plug in heater uses 1500w, a Kw is 1000 watts so 1500w=1.5Kw
kWh is 1000 watts for 1hr, a device drawing 2000w for 1hr would = 2kwh, for 30 minutes would be 1kWh, etc.
SOC is the shortened version of State Of Charge
SOH is the shortened version of State Of Health, measured with something like LeafSpy(a user purchased program that works in conjunction with a device that plugs into the OBDII port on your car).
L1=120vAC can be as low as 6a or high as 27.5a with a Leaf, depending on your charger and of course EVSE.
L2=208-240v can be as low as 6a or high as 27.5a with a Leaf, depending on your charger and EVSE.
L3 AKA QC feeds DC directly to the car, bypassing the cars built in charger resulting in potentially much faster charging, eg 80% charge in 30 minutes, speed depends on the charger as well as SOC of battery and temperatures.
Note in Europe and other countries that use 220v for their standard outlets I believe they may differentiate between L1 and L2 by the charging speed......not sure about that one. Being a higher voltage their standard outlets max out at a lesser current than our 15a or even 20a standard 120v outlets.

That's "CCS" or "SAE Combo" or, in Leaf circles, "Frankenplug" which is unfair because it's a simpler, better design than Chademo that uses one port for both L-2 and DC Fast Charging.

The VIN # looks weird, they usually start with 1N4. Too bad, as the trick to get the original sales sticker is handy for seeing the original location it was sold in and what options it had:

viewtopic.php?t=23716

You should check when it was made (door pillar), as you want a LEAF that has the better battery chemistry (anytime from April 2013 onwards has the improved chemistry).

Also, you're probably going to need to buy a new 12V battery, that voltage is pretty low.



Still a bit new to LeafSpy... what line on the LS page shows the 12V battery voltage level?

It's on the main screen, when you first open Leaf Spy, in the bottom right corner. In this case, 13.04V

Since LeafSpy can only read the car with it on, the accessory battery voltage will always read much higher than at rest with the car off because it's running on the DC-DC converter. I wouldn't go by that.

Agreed, it's not something I find very useful, but the OP did ask...

Briscoebully, you have to measure the 12 volt battery voltage with the car off, after 15 or more minutes, without opening a door (you can just pop the hood before leaving the car). Use a multi-meter. Typical voltage for a 2013 Leaf is 12.6 volts or less. Below 12.4 volts and you will likely have problems.
