AeroVironment™ DUAL-FLEX CORD SET

Tue Jun 22, 2010 9:26 pm

Is this what we want - a portable 110/240 J1772 EVSE ?

• 120VAC or 240VAC power source flexibility in one cord set
• Power source auto detect and
• Auto start and restart in event outage or ground fault
• User friendly LED display
• Outdoor rated enclosure and ruggedized design
• Multiple cord length options
• Easily interchangeable cords

The ruggedized and flexible Dual-Flex cord set will accommodate your everyday home charging regimen with the added benefit of supporting you when you’re running low on battery range without a charging station nearby. Built-in intelligence will automatically distinguish the input power to auto-select the proper charging rate between 240VAC and 220VAC – and the featured SAE J1772 connector will allow Dual-Flex to work with any modern EV that conforms to this industry standard. Additionally, our Dual-Flex design comes with multiple cord length options that are easily interchangeable. Dual-Flex can be used while at home, on travel and for EV service businesses, such as dealerships and emergency roadside assistance.

That sure looks like it. Will handle up to 240V @ 30A, so a "standard" dryer outlet... which anyone with an electric dryer has (who you might be visiting), and they are fairly inexpensive as well...

30A 240V Dryer outlets are INEXPENSIVE. I just bought a fancy range outlet (L14-50R) which is a 50A 240V version for $8.00 @ Lowes. I didn't say the portable EVSE would be inexpensive... Just if you need to install a standard 30A dryer outlet, it's not going to cost that much.

people are a bit jumpy, no? :)

Nope just trying to find out pricing on these things. So far there are no prices on any of this equipment. The only thing I have found is that the J1772 plug is going to be around $900 without the box on the other end of the cord. So all these EVSE "boxes" are likely to be well over $1000. Hopefully the prices have come down now that they are manufacturing them in greater quantities, but until we see some pricing somewhere, its all just guesses.

From the http://evsolutions.avinc.com/uploads/pr ... 061010.pdf PDF file:

Is that a TYPO ? Do they mean "rate between 240VAC and 120VAC" ?

What we don't know is what is on the other end (the one that is not J1772). How will it go into both 120V & 240V - adapters ? Is such a thing even available ... ?

Yes, type. Auto voltage selection between 120/240VAC.

BTW, "Yazaki" (mfr of J-1772 connectors) is massive... can't even find them on any of their sites..

Well, yes, in a meaningless sense. You can always connect a 120v plug to a dryer outlet, but you get 120v when you do, because you are contacting only one of the two 120v legs.

But you are right, they haven't explained what is on the other end. They have definitely not said you can plug it into the wall, only into their EVSE.

"Dual-Flex is being designed to work with your home charging dock (EVSE) and will also be portable for you to carry in your EV’s trunk for emergency charging while you’re on the road."

And:

"Emergency charging using any readily available 120 VAC (Level 1) outlet."

It doesn't say we can connect to 208-240VAC on the road - but it does say we can connect to 208-240VAC at home if we connect to our EVSE.
