Level 3 at home

[jjeff]

Anything charge at even half that speed yet on J1772?

Yes. Early Model S came with 40 amp OBCs and you could get a 2nd 10 kW OBC for 80 amps of charging (e.g. https://web.archive.org/web/20131125013 ... rd-charger). IIRC, some of the highest trims/versions came w/that 2nd OBC standard.

Other Tesla-powered EVs came with a single 40 amp (10 kW) OBC like the gen 2 Rav4 EV and Mercedes B-Class ED.

Eventually, Tesla did 48 amp and 72 amp OBCs and stopped doing 80 amps. Now they only equip US vehicles w/32 and 48 amp OBCs: https://www.tesla.com/support/home-char ... rd-charger. https://web.archive.org/web/20180915023 ... rd-charger was from after they ditched 80 amps of OBC. https://web.archive.org/web/20160801032 ... stallation near the bottom has references to 80 amps of OBC. https://web.archive.org/web/20121207085 ... m/charging has references to 10 and 20 kW of OBC.

Their included J1772 adapter can handle 19.2 kW per https://shop.tesla.com/us/en/product/ve ... apter.html.

I believe the original Roadster could do 70 amp charging: https://www.greencarreports.com/news/10 ... ge-adaptor.

Model 3 MR, SR and SR+ was the first time any Tesla-branded vehicle for the US came with below a 40 amp OBC.

We have numerous 72 amp OBC Teslas at work and some w/80 amps. Since our ChargePoint J1772 EVSEs are only 30 amps max, many of them use our Tesla Wall Connectors. We have them currently on a load sharing arrangement. Each master/slave pair is on a 100 amp circuit w/80 amp max load. If one side isn't plugged in or is done, the other side can be allocated the full 80 amps.

This doesn't help us and isn't J1772 but the old Renault Zoe had a Chameleon charger that allowed for up to 43 kW AC charging via 3-phase power: https://transportevolved.com/2014/12/16 ... -charging/.

Nice informative post
Not to derail this thread but for any of the cars that had a second OBC, did any of them allow plugging in a second J1772 connector? Most of the time I charge at my local stores that have Chargepoint EV connectors, they have 2 J1772 cables and the second one is hardly ever being used. I've often wondered if some cars would allow me to utilize both at the same time, to get double the charging speed or roughly 60a of charging. Of course then one would probably need a second Chargepoint card?? as I'd assume maybe you could only use one charge station at the same time per card??

Did tesla discover there isn't much demand for level 2 charging in excess of 40 amps?
My chademo peaks at 8kw, it averages about 7.2kw over the duration of the charge.
That seems like enough for me for home level 2 charging.

...Leaf owners are cheap as hell.

Beg to disagree. Ordered my LEAF in 2010 for a $99 deposit. Back then a deposit on a non-existent car was a huge risk or lunacy, your call. When they became available, my supposed 2011 model became a 2012, and I took delivery Feb, 2012. Out the door it was almost exactly $40K, not a small amount now or back in 2012. I was cheap enough to not get a Model S or Roadster, but $40k is still a pretty good bag o’ shekels, at least pour moi.

You are a vestigial example of what I am pointing out; you were a very early adopter of the LEAF who most recently bought a Tesla. Would this product interest you more if it had a Tesla plug ?

It is an academic question because only CHAdeMO supports B2G for now. I ask only only to point out that the LEAF is a stumbling block when it is part of CHAdeMO B2G

I totally miss the leap from my posit that not all LEAFers are “cheap as hell” to whether this product (I’m guessing you mean the Level 3 at home) would be of interest. Must be my “vestigiality” though I’m not sure I like being put into the same category as an appendix or gall bladder. Sticks and stones, I guess, and as I finish my martini I’m getting very very low readings on my give-a-shit meter.

If it matters, Level 3 at home is not something I’m interested in regardless of the type of plug. Typical L3 is DC power but I get AC from the power company so I have to buy something else to convert. That something is large, expensive, and totally unnecessary since that thingie already exists inside my LEAF and my Model 3 sized to support, for me, adequate charging speeds. The LEAF doesn’t matter because even at full charge it doesn’t go very far. My LR Model 3 already charges up to 32 amps in my existing set up and if I wanted faster, I’d spend the $500 and get the Telsa wall unit to go up to 48 amps. That would be a much less expensive solution than going for L3, the higher charging speed of which I don’t especially need.

^^ lol !
Vestigial, as in

forming a very small remnant of something that was once much larger or more noticeable.

Your reasoning makes sense to me, and I think the same. But lets say you had a desire for or use of charging in the 25 kW range and DC charging was the only way to get it. Can you imagine it being paired with a LEAF, or would you want it to pair with your Tesla ? For me it would be the Tesla because of the degradation that follows the LEAF without thermal control.

Unfortunately, no US Teslas have more than 1 inlet, so no. Would be nice.

I've met the guy at https://insideevs.com/news/323568/iron- ... -24-hours/ and his electric motorcycle could utilize several J1772 plugs at once. He mentioned it to me. I hadn't even seen that story until now.

I was actually looking for a CHAdeMO unit that would work with a single-phase 208 or 240-volt input when I had my 2011 because its 3.3 kW onboard charger was slow. Once I was forced to replace the 2011, I found the 6 kW charger in the 2015 to be sufficient for my needs so I stopped searching.

I believe the Tesla Semi has multiple charging ports to speed charging for its humongous battery. But no, none of the automobiles does.

When the EV, DC charge ports allow protocols for bidirectional energy, and "level 3" energy converters have both solar MPPT inputs and code compliant grid/emergency panel transfer switches (240 VAC split phase), then I'm in! Seems Nissan is getting close to actually sanctioning (warranting) the bidirectional part. We'll see.

The V2H part with Leafs via CHAdeMO has been going on in Japan for years.

Unknown off the top of my head if it actually works on US market Leafs and on which model years/build month ranges.

IIRC, Leafs since somewhere around 2015 or 2016 Have the capability.
