FutureFolly said:This has a lot of potential as the basis for residential L3 charging. I think it would really only be practical with the CCS plug too. I'm not sure you could license the plugs or protocols from Tesla or CHAdeMO very easily. Also, with both your costs would go up dramatically because you couldn't use the OBC to speed up charging.
Not true for CHAdeMO. Just pay about $165 for the plans. It's open architecture.
Here's a good overview how it works:
http://www.chademo.com/wp/technology/details/
For Tesla, it uses the same SAE "Frankenplug" logic and PLC communication, with substantially higher power capable connectors at far lighter weight and smaller size. Of course, it uses a common pin for AC and DC power, unlike Frankenpkug.
Since the Americans and Europeans are supporting CCS you should really be thinking about a broader market than just the Spark. The i3 uses the rare 32 amp J1772. People that want the most out of their vehicle will probably spring for the more expensive home charger and the higher quote from the electrician for installation.
The "Americans" aren't using CCS; General Motors is. The largest American EV manufacturer, Tesla, will never use the CCS Combo 1 or Combo 2. Ford has no public plans for any CCS car, nor do they have one. Chrysler is majority owned by Fiat, and their headquarters is moving to Europe. Of course, Fiat, like most of the world's auto manufacturers, does not support CCS, nor do they have or have publically announced any future CCS.
Yes, every German auto manufacture supports CCS. No others in Europe, or anywhere else in the world, have signed up for CCS.
30/32 amp J1772 isn't rare at all; it's the norm.
When they find out that their car was designed with a DC socket that will eventually be useful at DC-FC stations that might exist near them someday, they will be apathetic. When they find out that their car was designed with a DC socket that can work with a home charger that cuts the charging time in half because it uses the OBC and a garage installed DC charger at the same time, range anxiety will start to melt away.
This has actually already been done with CHAdeMO. A portable charger that you can plug into a NEMA 14-50R, and charge a car through its DC port at 10kW (40 amps continuous @ 250 volts from "the wall").
I wouldn't try to sell a 3.3kW off-board charger for more than $1,500.
Good luck at that price point!!!
