pchilds: You wrote "Why would a quick charger be a continuous load for residential use?".

From the 2014 NEC Article 625.40 (Overcurrent Protection): Overcurrent protection for feeders and branch circuits supplying electric vehicle supply equipment shall be sized for continuous duty and shall have a rating of not less than 125 percent of the maximum load of the electric vehicle supply equipment.

As to why this is the case, perhaps they want a rule that easy to remember, i.e. ALWAYS 125% so that there is less likely to be confusion. Also, in the future there may be a vehicle connected to that EVSE with a much larger battery pack that DOES take over 3 hours -- the NEC is taking that possibility into consideration, as it should.

And it only eats up the entire trunk space! :lol:
Sorry, but I fail to see the utility here...

We charged Leaf to Leaf @ 110amps, it will charge from a 2013 or 2014 Leaf to any CHAdeMO equipped car.
59,991 miles/12 bars/289 Gids/68.54 AHr/101% SOH/101.64% Hx 7May15 w/ new Lizard (barely made the warranty).
71,770 miles/12 bars/256 Gids/59.04 AHr/88% SOH/87.92% Hx 3Mar16 at lease return.

Now driving a 2016 Volt Premier.

ORCA Inceptive list price is $25,990.

Soon we are going to make a low cost model "ORCA Portable" that will work up to 20 kW and it will be also smaller and lighter. Expected list price is $5,900, but it is not available yet.

I think I will save my money for a replacement traction battery (assuming Nissan starts selling them eventually).

We are not talking adout EVSEs, we are talking about DC chargers. This rule is not relevant. :D

pchilds: I will agree that the NEC is having a tough time keeping up with EV technology innovations these days (a new NEC is released only every 3 years), but I think my basic reasoning is relevant. If not, please let me know... :)

Very nice! How are you convincing the source battery to close contactors? Is the vehicle in drive mode? Or is this a bidirectional Chademo instruction (only 2013/14?) If so, what's the byte instruction on the 108/109 CAN message from the "charger" to close the contactor but not command charge current?

Is the "ORCA Portable" only for car-to-car, or will that also work off grid power? If you guys come out with a 20 kW CHAdeMO station for only $5,900, that will be a true game changer. That is about the same as what ChargePoint charges for a CT4000! I still dream of seeing 2-3 CHAdeMO stations per location instead of just one. 50 kW max across all 2-3, whomever plugs in first gets priority with a minimum of 6 kW output. Doesn't seem like many people are interested in installing more than one QC / location aside from Tesla, though.

If the price were right - rather than encure the charging loss of charging another leaf, why not just simply use it to get your car down the road a whole lot further. That's what I'd be thinking about. I remember that Phil said that such an application wouldn't be cost effective - so I'm wondering what if anything has changed.
