Single phase CHADEMO at reduced charge rate. Possible???

Sun May 28, 2017 6:57 pm

So not an engineer here but curious as to why this kind of a CHADEMO charger hasn't been developed. I would think there would be some market. A home based single phase unit that could provide a 15 KW DC charge etc. Curious if people think there would ever be a market. Those with cars with 60 or greater KWH batteries might find them handy.

Hey that's kinda cool. But I'm not sure what I'm seeing. It mentions max 40 amp output max. So at 240 volts that is about 10 KW. Not a huge jump from the internal 6.6. It would be cooler if it was 70 amp unit at 15 KW. But still kinda cool.

This seems to be the same Chinese charger unit that created some discussion a while back... The idea of pulling power from high AMP EVSE stations is new to me... Owning an older LEAF with L3 makes this tempting... If I had 2 LEAFS, more so, or a delivery fleet, especially...

I believe this is the supplier of the actual charger/controller (maybe rebranded and/or simply added different cabling options):
http://www.setec-power.com/prlist/278603-3.html.

Setec also makes a stand-alone 50KW solar/off-grid charger/controller - things are starting to get interesting!

As I understand anyone with a 2014 and later Leaf can also use CHAdeMO connection in bi-directional current flow - any information on that?

The Setec unit is limited to 30 amps at single phase AC input. That would be ~ 7000 watts with typical 240 VAC split phase in US (would be interesting to see how they handle split phase inputs - 120 VAC to neutral?). With CHAdeMO, it is direct DC charging the Leaf's battery at ~400 VDC for a much higher efficiency of charge than level II. For us with the 3.3KW charger, it will allow charging a couple of times faster - but at a price as usual! If you can find a 380 VAC input you can get the full 10KW.

You are being bit by the forum "feature" that adds referral codes to links posted. In this case, it screws the whole link. And worse, it does it at display time.

You need to turn off "auto parse URLs" when posting and then use font size changes to prevent the stupid forum code from ruining the display of the URL:

Code: Select all

Most ChaDeMo chargers need 3 phase power because it's 477V AC, so it can easily be stepped down slightly and rectified to the 365V-385V DCrequired for a EV battery. 220V AC rectified to DC is only about 250V DC, way too low to charge a EV battery.

The portable CHAdeMO is great for those of us with the 3.3KW onboard charger. Bypassing it and use the CHAdeMO connection with this portable unit, it takes little more than a third the time! I've had one for two years, and it's still going strong. It's true that the large CHAdeMO stations use three phase power, but this portable one operates on single phase. I plug it right in at campground outlets, and I use a J1772 adapter at charging stations to double the speed, pulling 6.6KW even though my car's onboard charger is limited to 3.3.

Nice. Where did you buy your unit and how much was it.

Thanks.
