One more comment on the question that started this flood of comments. Yes, J1772 is architected to support DC (external charger) in addition to AC (internal charger). But the Yazaki J1772 connector, which is what we tend to think of as J1772, and is what most if not all EV and PHEV makers seem to be adopting, is only approved up to 30A, 240V.

I believe the second charging port on the Leaf is not J1772-compliant at all, but is JARI Level 3 DC. That's a different standard that several Japanese auto makers have been pushing.



The JARI is the one used for an external charger not the other. One is for AC only on the LEAF.

Can anyone explain this to me? The way I read it I need a 40A breaker.

This is from Nissan's Leaf website;

A: The home charging dock will require a 220/240V 40 amp dedicated circuit connected to a breaker. The charging dock will need to be hard-wired directly to the circuit by a certified electrician.

Thank you for explaining :)

3.3 kW charging, 240v 15a, requires a 20-amp breaker to be in code for a "continuous" load (charging).

6.6 kW charging, to be available when the first Leafs are "upgraded", uses 30a from the 240v circuit, requiring a 40-amp braker (at least 125% of the continuous load) to be in code.

Thus, for now, a 20-amp circuit would be enough, but might as well wire (and size the breaker) for the comming-soon faster charging ... if possible.
If not possible, wire the 20-amp circuit and just stay with that "8-hour" charge rate.

I have a copy of the Jan 2010 J1772. Level 1 and 2 are covered by J1772 and while it does provide data for the Yazaki connector, it also includes info for the 'previous' square coupler.

The J1772 doc does talk about Level 3 within the context of the earlier revision, but makes it clear that while Level 3 was never previously implemented, it is 'under development' for the current configuration. The J1772 committee should be voting on the new DC Level 3 configuration in late June.

For the Yazaki Level 1 and 2... The pilot/control signal upper limit is 80A. The Level 2 charge ratings are specified to be 208-240V single phase AC at less than or equal to 80A. This connector appears to be designed and specified for Level 1 and 2 AC connection at up to the 80A continuous rating.

The earlier square connector appears to have a 40A limit for AC charging. It did have an option of including DC Level 3 charging at up to 600VDC and 400A, the J1772 doc clearly states that Level 3 has never been implemented in the US.

The quick charge port - likely to end up being the Yari/TEPCO configuration will be included in J1772 once ratified.

Although most buyers of the Leaf won't use a fast DC charger, it's an important feature for the EV industry in the future.

The EV Project that's installing EVSE's and chargers for Nissan in early adopter locations has hundreds of fast charging spots planned.

If SAE is too slow in setting the J-1772 DC fast charging standard, Nissan could set the "de facto" standard in the US.
Maybe SAE will just choose to let Nissan's chosen standard to be the SAE standard.

I hope this is true because my installation is very easy. I have a 200 amp service panel outside my garage that feeds a 125 amp panel in the center of a 3 car garage. I will mount the charge station on the wall directly next to this sub-panel which will allow the cord to reach all three garage stalls. I should be able to get it all done for about $500-$750. Worst case it has to be mounted on the wall next to the 200 amp panel and the charger can only reach two of the three stalls.

Jonathan Read, president and CEO of ECOtality (the company working with Nissan to create home charging stations for the Leaf EV), told The New York Times that the hardware for the charging station will be around $300 to $350, and typical installation costs will range from $500 to $1500. That's for homes equipped with a typical 200-amp or higher electrical service. According to Richard Lowenthal, CEO of charging company Coulomb, the cost of installation could increase to as much as $10,000 “if new service and panels are needed.”

I remember reading this .... we don't know whether Nissan's $2,200 is a minimum, optimistic, average or pessimistic number. We will know in a few weeks ...

The 2011 Leaf will come with a 3.3KW charger on board.
The 2012 Leaf will have a 6.6KW charger.
It will be possible to upgrade the 2011 with the faster charger (at extra cost) when the 2012 model comes out.


I know that this is a very old thread, and I know that this topic has been addressed in other threads, but I feel that the following subject needs to be addressed.

Where has Nissan - in a publicly available press release - announced any of this?

I have also seen others say that future LEAFs will have a 6.6kw charger. I have seen no one site Nissan as the source (other than one Nissan online chat, where the operator said basically that everything was subject to change). I mean, let's face it, Nissan hasn't even finalized specifications of the 2011 LEAF. Now all of this may actually come to pass. But I won't believe any of it until I see a Nissan executive say it, or see it in a Nissan press release.

Leafguy: I really appreciate your efforts to keep the info on these posts factual---instead of rumors and hearsay. I wish we could all limit our posts to FACTS. There's way too much BS being put out here :)
