The link just goes to Amazon. I have a 200 amp main into my house. How much throughput could I get with something similar to your level 3? (Without a battery intermediary)
I have a 200 amp main and ran 4 gauge on a 100 amp breaker to the garage to run my little aluminum welding setup. Miller recommend a 100 amp circuit for that machine.
If I was going to use that circuit for charging, I take out the 100 amp and install a 90 amp breaker so it would be to code for a continuous load and would be good for up to 18kw.

Last I heard j1772 was approved for 70 amps which is almost 17kw on single phase 240v.

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/.

Home level 3 has no use whatsoever... Unless you are taxi or delivery service.

The only benefit of Level 3 is TIME. However, when at home, we all have time. Also, most EV customers drive LESS than the capability of the Leaf. So many Leaf owners drive only 5-10K miles yearly, so a Level 3 has no value.

Heck, many still only charge on Level 1. And Leaf owners are cheap as hell.

I can confirm that my 2013 Model S P85 has two 40 amp on-board chargers. I installed a 100 amp circuit to charge it with a Tesla wall connector and occasionally charge at 80 amps. The display in the car says it's about 55 or 56 miles per hour...

In the early days before all the Supercharger infrastructure, I found a few places to charge on road trips that had 70 or 80 amp Level 2 chargers. Some were left over from the Roadster network with J1772 plugs now installed (Rabobank, etc.). We were able to go to several places along the way and get a decent rate of charge.

Now, it isn't as necessary with all of the Superchargers out there. But it sure is fun to hit it in the garage with 19 kW. No demand charges yet on my residential service.... :)

There was a fairly large cohort of real early adopters that paid msrp for the Gen1 LEAF and could be viewed as potential customers for bleeding edge tech but they have abandoned the LEAF for Tesla.

I've thought about this thread some more and I continue to think that commercial livery/delivery would be a reasonable target audience. The problem is the car. If the LEAF ever gains battery thermal control it would be time to revisit this.

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
