What I'd really like for a 2014 Zero S is a slightly smaller charger that can utilize J1772 at 7kW for the public EVSE's that are available with 220V at 30A.  If I could carry 2 on a rack, then I could use multiple J1772 plugs when they are available for a total of 13.2kW of charging goodness!

Haha Ben! You're talking my language! I like it!  Yes of all the options right now I think the EMW charger is the best bang for the buck, space and weight.  I went by his shop a month ago and tested a 2014 DS with his portable CHAdeMO unit.  Just amazing!  His charger is so powerful and tiny.  I'm thinking you power it with dual J1772's to max it out, or a single J1772 most times for 7 kw charging.  I think it will fit and be waterproof in a GIVI top box.  Then open it (when its not raining) to charge.

I wish that EMW made a 6KW charger on the same design specs... if they could cut their SmartCharge 12KW in half and get it down to 12 lbs and 6X6X6" it would be the perfect onboard motorcycle charger and could replace the OEM charger.   Add another outside the bike for road trips.

It looks like EMW is also working on CHAdeMO charge station for this Spring.   It sounds like it could work with lower voltages for Zero Motorcycles.

Some of these mounted around your riding area + Factory Zero CHAdeMO option would be the best for cost + not having to add a lot of weight and volume to the motorcycle although Zero charges a lot for the CHAdeMO option at $1,800.  I am not sure what is involved in the Zero kit but that seems like a lot for a connector.   As I understand it CHAdeMO has the advantage of DC charging, so it should not require an AC/DC charger on the bike, only some electronics to communicate appropriately between bike and charge station and the connector to connect the DC charge directly to the battery bank.   This seems appealing in terms of making the bike simple and light but if they aren't anywhere to plug into it is of little use.

It seems like CHAdeMO is not catching on and there are more J1772 stations deployed and more future for that protocol?   I would guess that it is lower cost and lower cost usually wins in the end.

Hi Terry.   Please elaborate a bit on testing a 2014DS with a portable CHAdeMO unit.   You are taking the CHAdeMO unit and connoting it to 240V sources or the CHAdeMO unit is stationary and you are connecting a 2014 DS to it with the factory Zero CHAdeMO option?   Was it this unit:  http://emotorwerks.com/products/online-store/product/show/97-new-chademo-tm-compatible-charge-controller-for-emotorwerks-dc-chargers

Most CHAdeMO chargers are very expensive to purchase, and even more expensive to install the 480V AC supply. Nissan's QC is "cheap" @ $15k is "cheap", and I hear all-in cost to install is $50k. J1772 requires only 240V AC supply, and the EV supply equipment is relatively inexpensive ($500-$1000).

CHAdeMO installations ARE increasing, but they're certainly less common than J1772 AC installations. It doesn't help that the Nissan LEAF is the only common EV sold in the US that is compatible with the CHAdeMO standard.

Jan 2011: 539 worldwide CHAdeMO installations
Jan 2012: 1009 worldwide
Jan 2013: 2364 worldwide (154 US)
Jan 2014: 3500 worldwide (554 US)

A 240V 100A circuit could be split several ways to charge EVs.

* 20 kW, single 125A DC CHAdeMO charger (20 kW LEAF, Mission R, Model S; 12 kW Zero)
* 20 kW, single 80A J1772 EVSE (20 kW Model S twin-charger; 10 kW Model S, RAV4, Mission R; 7 kW most other EVs)
* 2x 10 kW, two 40A J1772 EVSE (10 kW Model S, RAV4, Mission R; 7 kW most other EVs)

EMW has a portable CHAdeMO unit.  You could probably carry it with you in a GIVI case.  You plug it in to a voltage source.  Single or multiple J1772 or NEMA 14-50 would be my suggestion.  Then you just plug it into the port on the bike.  If you go on a ride and 3 other riders also have a CHAdeMO port, you could charge up everyone for 20 min or so if you say ride to Yosemite and back. 

The other cool thing is you can assist other EV drivers that might have run empty.  Valery from EMW is working on a direct connection to the battery that will power the unit.  You and your Zero can then become a mobile CHAdeMO station!  It may take a second to realize how significant this is....

[WindRider]

That is perfect Terry.   If I understand you correctly they are working on this device:

http://emotorwerks.com/products/online-store/product/show/97-new-chademo-tm-compatible-charge-controller-for-emotorwerks-dc-chargers

Which is only :

Weight: 4 lb
Width: 8 in
Length: 12 in
Height: 3 in

And with that device and the Zero CHAdeMO option installed along with various input electrical connectors you could potentially quick charge at any voltage source that had enough power ?

This is just the controller hooking up to the charger and then to your CHAdeMO port. That port cost $1400 through zero btw.

The charger works with their 12k 20 k and 25k chargers. I know the 12k would require 2 J1772  30 A to use at 12k for our purposes., no clue what would be required for the 25k charger.

That stated I would still like the chargerand if someone can give me a good reason the CHAdeMO controller.

[benswing]

Windrider, this is the device we're looking at, an onboard charger that can plug into your bike using ChaDeMo and is powered by a J1772 plug:

I believe Electric Cowboy may be working on a version of this that is 6 or 7kW that would take the place of the tank area on a 2014 Zero.  That way you could put on a charging unit instead of an extra battery to go on longer distance trips. 

I'm curious how much extra electronics would be necessary to change the 12kW charger already available by eMotorWerks to have 2 inputs so you could charge with all 12kW using 2 J1772 plugs.  That is my dream!  (I think Terry might like one as well...  ;-) )

[Burton]

I don't think it would be too hard. You might have to make an EVSE with the two J1772 inputs then an output to your EMW12K

http://www.teslamotorsclub.com/showthread.php/8661-Adapter-to-combine-two-30A-level2-into-one-60A-J1772-faster-charging/page4

I sent an email off to EMW asking them what would be required and will post the info when they get back with me.

The phase of the two different circuits are the most difficult part to figure out. 

The guy you linked to had that issue:

"Three phase is definately a problem. I tried two different stations tonight and they both appeared to be different 3 phase legs. With most charging stations being on 3 phase power there may be very few places I can use this. I will keep testing but as of today things are not looking hopeful." 

If someone could figure this out, I'm sure more people than motorcyclists would be interested.

[Electric Terry]

To solve this an easy way is to package your charging solutions in 7kw or less packages that are isolated.  Then use AC from different J1772 sources.  I charged with up to 4 J1772's last year doing this.

I hope Valery at EMW has a solution for the portable CHAdeMO

[Burton]

Wont the CHAdeMO only be a controller which hooks up to their EMW25kW unit which would take 3 or 4 J1772 power sources? >_<

[benswing]

If Valery (or anyone) can come up with a portable 7kW charger that doesn't need to be liquid cooled, then there are probably a lot of people wanting it!  Although combining two J1772 plugs into 1 ChaDeMo connection also would be pretty sweet.

Imagine that.  Turning any 2 J1772 Outlets into a double-fast charging station.  Over here on the East Coast where there isn't a crowding problem at charging stations, that would work out quite nicely!
