Portable Chademo?

Wed Sep 07, 2016 7:47 pm

While looking around online at ev chargers, I stumbled onto a listing at Alibaba for a 10kw portable charger that takes a 220 and allows you to use Chademo to charge at 10kw. Am I reading this correctly or missing something in what they're offering?

Who's going to order one and try it out?

I like the blue hot wires feeding out of a bush.

It costs USD$3,500 for one of these puppies. Group buy > 4 units is USD$3,000 a piece.

A bit too expensive IMHO.

I'm curious in the tech behind it. If China has a bunch of these coming out, I'd imagine it would come down in price. The ability to avoid buying a Bursa/aftermarket charger to increase charge speeds by having a suitcase sized Chademo is interesting.

I have personally tested this unit on my 2012 Toyota RAV4 EV (with JdeMO). Yes, it physically worked.

1) Poor quality
2) Questionable durability
3) I do not find this unit to be CHAdeMO compliant, as I saw no insulation / isolation test. There may be other shortcomings.

Caveat emptor.

There is another low cost unit from China that I did like. I think it is about $6000, and slightly bigger, and uses a RFID card to operate it. It's not really portable, but neither is the other. Yes, you could haul it around.

I'd consider...wonder about the warranty claims to China... They are all wire transfer deals...

China is good and bad. Left alone they are junk. With supervision they turn out a quality product. You pay your money and you take your chances.

The bad thing is that you never know until you receive the first item. For example, Dostar J1772 cables work but the cable from Quick Charge Power is superior.
2012 Cayenne Red SL traded for:
2013 Pearl White SL Premium
Traded for a Cirrus White 2014 Mercedes B (totaled)
2016 Urano Gray eGolf SEL w/ drive assist
Loved the VW but it sat too low for my old body
Back to a Cirrus White 2017 B250E

Thinking out loud. Given these are more complicated than an EVSE, one wonders if there is any expectation that a home or business could opt for such a unit... A delivery service using LEAFs might benefit from one. A family with a couple of LEAFs and multiple users might... Wonder that the sweet spot is in a price point for that?

I have a full sized CHAdeMO charger on the side of my house, and it can be programmed all the way done to 60 amps DC (about 24kW in a 400 volt car). Still too much for my 200 amp panel at my house.

200 amps would support a 10KW fast charger, wouldn't it..presuming the house wasn't heavily electric (space heat, water, etc)? I really don't know... Asking. I do know that I am tempted at $3000 to be able to charge at will... At $1500-1700 I'd buy one.
