L3 (DC-QC) variations

Doing a DC Quick charge at about 14 kW (240v x 60A) would charge the EV "more gently", perhaps even charging to 95% in under 2 hours.

Such a DC FC (Fast Charge) could be powered at home, and not cost "too much".

With the charging taking only 2 hours, it might not even be considered a "continuous load", so one might be able to use a 60-amp breaker and circuit (I am not sure).

Since the 14 kW is a LOT less than the 50 kW of the "DC QC", this would typically cost a lot less.

Perhaps this is a good idea for a home Fast-Charge device?

Manzanita Micro PFC-50, 12KW charger, could be adapter to the Leaf, if Rich Rudman had a Leaf to try it with and also the documentation on the DC Fast charging protocol, to communicate to the vehicle.

The PFC-50 is $3300 without the additional control interfaces needed to communicate to the Leaf.

That MM power supply is only 12 kw, not 15, and that thread appears to be MM-specific.
But, thanks for the links.

Learn from what has occured in the past, there is almost nothing "new" under the sun. This has all been done before.
you are not going to do much better than 12KW in any residential setting, and you are probably not going to be able to beat the price of the PFC-50 either.

ok, then use his PFC-75 (18kW) charger instead.... http://www.manzanitamicro.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=43&category_id=14&option=com_virtuemart&Itemid=64&vmcchk=1&Itemid=64

and if you want 60 amps, then just turn it down with the provided knob.

Too bad AV does not offer such an option since they are already having everyone install a 40a circuit.
This may well be the better option to bypass or upgrade the onboard 3.3Kw Leaf charger.

No specs online (that I can find) for the "70" unit.

No argument that a current-controlled DC Power Supply is essentially a commodity. Price and spec details limit the choices, and MM might be a good choice.

Hewever, the real issue is building an "interface" - to communicate with the EV and "regulate" the current flow.

Apparently only the CHAdeMO Association members have the "communication protocol" specifications. Until we can get that info, or reverse engineer the communication, we cannot adapt units like the MM "70" to charge the LEAF.

Yes, a DC-FC might be only $6000, but we need more information.

Apparently others are too busy selling $15k units for $60k to bother with a "mini" version.

This has been discussed many time. Do we really need a separate thread on the variations of QC chargers? The Leaf wil have one dictate the communication need. What next, a thread on QC colors?

I want a glacier pearl QC to match my car.

I want a "flame" theme. That makes it charge faster! Right?
