warning in the manual

Tue Sep 20, 2011 11:10 pm

FWIW, in case you hadn't noticed, there is a general (probably CYA) warning in the manual on page CH-11:
Only charge using a standard 110 - 120 volt, 20A dedicated electrical outlet (For example do not use an electric generator). Failure to do so may cause charging to fail and could cause damage to the Li-ion battery charging equipment due to power surges.
A Priuschatter from Japan has noted that the JDM Leaf's manual has a similar warning.

Take it for what it's worth (or not).

'13 Leaf SV w/premium (owned)
'13 Leaf SV w/QC + LED & premium (lease over)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I have charged L1 using an ETQ1800 I bought new for $359 on Ebay. Same deal ground error until I tied neutral and ground together. Then it charged like a champ. Slow as Christmas though.

And with Christmas coming September first these days, that is pretty darn slow! It also works fine with the Honda EU2000I by the way...

Hmmm, well just because you CAN do this, you think it's a good idea? Your putting out a lot of pollution with these low cost generators, kind of defeating the entire purpose of the Leaf.

Um, aren't ALL outlets powered by generators?

The wall (Grid-Powered) outlets usually have pretty good sine wave waveshapes, and only infrequent spikes.

A "modified sinewave" inverter (or generator) actually outputs a 2-step square wave, with the waveshape looking like a 2-layer wedding cake up, and the same (but inverted) down. So, it essentially has 8 substantial "spikes" each cycle, or 480 "spikes" per second.

Some electronics do NOT like that type of input, while some other devices do not care.

So, the "modified sine-wave" is NOT a sine-wave, but just advertising, similar to a "Range Extended EV".

Most generators are sine wave. Although they don't always hold a good pattern under load.

Charging from an inverter is kinda pointless unless you have a large off grid type system. And if so it is probably a sine wave inverter.

Phil mentioned a few posts back that the LEAF's on-board charger MIGHT take DC.

If so, that MIGHT mean that one (possibly modified) LEAF "donor" could charge another LEAF "recipient", using a special DC-EVSE from the donor to the standard J1772 input port on the stranded LEAF.

To be somewhat safe, the "donor" LEAF's high-voltage would probably feed a special "QC-EVSE". Depending upon how the donor EV's QC Port works, perhaps this very special "DC-QC-EVSE" would be connected to the donor car's QC port.

Yes, that would be cool if it would work ... safely.

Soon we will know many of the important QC-CAN Message codes.

I will periodically charge my Leaf from a Honda EU65is generator. This is because I have no power lines to my cabin in the mountains. I can get there by fast chargers, but have to get a full charge before returning to the fast charger. The trip is ~400 miles and I will use about 4 gallons for a full charge (I think...), giving me 100mpg. I think this is better tham using the 45mpg VW Touran 2.0TDI we also have.

The efficiency is around 25mpg, and probably less polluting than having to be flat-bedded out.
