Portable 40A EVSE for $361 versus Leviton for $1500

[TonyWilliams]

Any adjustable EVSE should have, at the very least, settings for 15, 20, 30, 40, and 50 amp circuits (i.e. 12, 16, 24, 32, and 40 amps.) Even openEVSE is stupid in the respect, as by default it comes with settings in 5 amp increments.

Tesla obviously figured this out, and has now added the 25% reduction in amps when meeting a certain heat threshold.

Awesome! And I thought I was getting a great deal on my $500 open-EVSE. Although, to be fair, from the EMW store if you get the "base assembled" juicebox ($249) and a 25' 70A cable ($229) that comes out to $478, and you still need to add a plug, unless of course you're hardwiring. You didn't get the 32A-rated cable did you?

That same "70 amp" cable assembly is now rated by the manufacturer at 50 amps.

We will have that cable available with an upgraded 3rd generation J1772 plug attached (we won't even use that goofy plug with the orange button) for only $185. The cool part about this plug/cable assembly is that it has a very heavy insulation and could probably handle the full 80 amps of J1772 over the approximately 6 gauge power conductors. Always check for excessive heating at any amperage !!!

All of our products carry a one year limited warranty. We also have the 32 amp assembly with lighter weight black cable for $145.

For the really astute EVSE aficionado, we will have custom parallel power conductor lightweight cables for 40 amps for a special price. There's nothing like it short of what Tesla does, and we have 1500 feet of that cable coming. As always, we can do mil-spec crimps on the pins.

As to some safety points Tony mentioned - we have addressed those before the KickStarter campaign was over - or about 4 months prior to Tony's posting. All units regardless of version have GFCI now

Great to hear. Looking forward to the next innovation from you for the betterment of all EV-kind !!!

Thx Tony. And thanks for pushing us to make a better product!

More coming soon.

This is great news Tony - such a cable would make a huge improvement in portability for any openEVSE / Juicebox or other kit EVSE. I've often wondered why the only J1772 cables available are rated for 30A or "70A", while there's almost no practical application of anything over 40A unless you have a dual-charger Tesla. And if you have one of those you clearly have money to burn so you'd very likely just get a HPWC anyway.

The reason has to deal with UL requirements for EVSE charging cables. You can't just use any multi-conductor cable (even if sized appropriately) and get UL approval for use in an EVSE.

But if you don't care about UL approval, then it's a fair game. After all, JuiceBox is not yet UL approved, either.

Tony - what's your price for 200 of these 25-foot cables with a J plug crimped? Could you pls PM me?

Thanks,
Valery.

We got our Rav4-EV last week which went a bit faster than expected so now I'm doing some quick research on EVSE solutions.
This forum has been great in educating me on the various aspects of EV ownership, of course particularly when it comes to the Rav4.
So far we love the car.

As far as I understand, the Rav4 charges at 40A max so ideally we should get a 40A EVSE. I really like a portable solution or at least one that is not hard-wired but rather plugs into a NEMA 14-50 receptacle. My contractor will be looking into the receptacle install tomorrow.
There are plenty of 30A solutions but not many 40A. There is Jesla, Juicebox, TucsonEV-SE and probably OpenEVSE.
Juicebox (and perhaps OpenEVSE) is the only solution with a timer? Should I worry about UL and if I do are any of these solutions UL certified?
Will I have insurance issues with any of these portable solutions?

Thanks much!

 

[fooljoe]

PearlRav, seems like you've got it pretty much figured out. Jesla's probably the most popular and cleanest solution but of course it's pricey. I'm partial to openEVSE because of full adjustability, and yes you can implement a timer - although I've never tried it out with mine (I just use RavCharge.)

If you are going to go the Juicebox or openEVSE route I'd hold out for one of Tony's new 8 conductor J1772 cables. The only other 40a-rated cables available for builders are pretty clunky.

I've never given a thought to UL certification. These are really simple devices - if a fire ever happens it'd most likely be due to poor house wiring or a poor/worn receptacle. But of course if you make a kit EVSE be very careful to make all the connections well and always use the proper components for the job. And above all else TEST IT - charge for a few minutes, check temperatures all over the unit, then repeat every 10 minutes or so the first time you use it to make sure there aren't any problem areas. Take a look at the J1772 handle and inlet each time you disconnect after a charge to make sure there aren't any signs of heat damage.

And that caution to test it should really apply to any commercial EVSE you buy as well. The only problems I've heard about have been with commercial units like Blinks, many of which had defective handles that overheated (Tony even had one melt to his car's inlet!)

Thanks fooljoe. My contractor told me today that our city may not permit an install with a non-UL listed EVSE (he said it depends on the inspector).
So the question is should we pull a permit on this or not...the contractor has done > 500 of these installs and is actually recommended by the local Leaf dealer. He doesn't care one way or the other.

By the way, why would the 40A cable be better than the 70A rated one?

So have him just permit and install a 14-50 or 6-50 outlet (whichever the EVSE uses). Hanging the EVSE on the wall, and plugging it in is a DIY job. As far as the 40a vs 70a cable, the cables get pretty thick and heavy as you go up. A 40a cable is already pretty big, and a 70a would be even more so.

Charge cables rated 40A and higher are quite heavy. I have the Leviton EVB40 and I think the 25' cable is about 60% of the total weight - and the Leviton unit is not small or light-weight. The EVB40 (both versions) is only $949 from Amazon right now, so the title of this thread is a little misleading. If you don't mind open-box, Amazon also has units that were probably returns available for just over $800.

Apparently the city wants to see the full solution including EVSE. They will not just permit the receptacle.

So how do people install outlets to use for a welder or such? Or to plug in their Tesla which comes with a 40a Mobile Connector?

they should permit the receptacle. it's UL listed and used by countless RV owners to plug in their RVs at their houses, ranches, etc. What you plug into that is your business, not city's

That makes sense. I'll discuss with my contractor. Mmh, with the drop in price for the UL listed Leviton unit it makes the decision a bit harder...I wish it had a timer function, but I guess RavCharge will do the job.

Exactly, I wouldn't even mention that the outlet is for EV charging - just ask for an "RV outlet." A 40a cable needn't be that large - the Tesla UMC / Jesla cable is hardly bigger than that which comes on the stock 120v EVSE thanks to the unique 8-conductor design which Tony's borrowing to make J1772 cables.

Well the forum seems to work better. Why dont you send me a quote for 200 units of your 25 foot 40 amp j cable to Valery at emotorwerks.com?
