Green Car Reports just posted an article re: a home charging advisor website run by Veloz and Electrify America.

Here’s a link to the home charging advisor website; seems useful.

I was just looking through that one too. There does not seem to be an option to filter by charge rate (e.g. 32A (7.6kW), 40A (9.6 kW), 48A (11 kW))?

Does ChargePoint offer a 48-amp home EVSE? I thought their residential units topped out at 40 amps.

Question about the 30% tax credit for EVSE. Can I purchase only the EVSE unit before end of year but not have it installed until 2nd half of 2021 and still qualify for the tax credit? Or is it purchased and installed before end of December?

Tax form stipulates “You placed the refueling property in service during your tax year”

which I assume means installed and turned on

Okay, hope they introduce some other incentive in 2021 on EVSE.

Case in point for why I'm installing my charger now and will App-enable prior to year's end.

btw: I changed my mind (again!) and am going with a 50A breaker and 6-50 plug-in application. The 40A charging (vs. 48A) is plenty for me and also facilitates a garage 220V socket for potential tools such as welder and cabinet tablesaw, especially as I'll not need to recharge daily.

When you mention "app-enabled" by Dec 31st, does that mean I can buy the EVSE and plug it into my existing 14-50 dryer outlet temporarily for a few days/week to enable it via app to qualify for the 30% EVSE tax credit? If so, then I can easily do that since I won't have it in actual service charging a vehicle until sometime in 2021.

I've read ID.4 has onboard 11kW charger, has anyone heard of any new EVSE on the horizon that will charge at 11kW with a plug? Per the ChargePoint Flex table above, will 60A breaker(48A) or 70A breaker(50A) achieve the 11kW hardwired charging?

There is a NEMA 14-60 outlet that was used for electric oven but very rare (and may not be in use anymore). 50A is really the highest Amp available for plug, if you want 60 or 70A, you need a hardwired unit.

That confirms my guess as none of my searches came up past 50A breaker(40A) for plugs. Will just leave the NEMA 14-50 as is on the #6 wires and swap in a hardwired EVSE along with a 60A breaker to get 48A charging in the future as need arises.

Per the ChargePoint table I attached above, I'm going 50A breaker and 6-50 plug-in application to accommodate 40A charging. Per-code cable was roughed in a couple years ago and I'm now doing the final socket/breaker terminations.

ChargePoint sells both a 6-50 and 14-50 model with the house power plug-in male cable type being the only difference (3 vs. 4 prong). I know because a 14-50 was incorrectly shipped first go-around.

Note: the Ground prong on the house power female socket must be at the top for ease of connection.

And yes, the way I read the Fed tax year 2020 form 8911only activation is required (easy via App) with no mention of actual EV ownership.

Progress thus far:

That was my assumption as well from reading 8911 but wanted a sanity check in case there were any gotchas. Nice install as I'm looking at the ChargePoint as well since one can upgrade to 60A(48A charging) via hardwire since I already had #6 awg in the wall.

FWIW, not all #6 can be used, see these earlier notes on a #6 cable thread.

I have #6 THHN existing wire in EMT to the dryer outlet.

I saw in another thread the VW ID. Charger Connect for EU. Will there be a single phase version from VW for the US when Chattanooga is in production mode?

Can you tell me more about this 'activation'? I looked on the Chargepoint site and I couldn't find anything about it.

All our U.S. specs. say 11kW charge acceptance, but that is a huge open question. U.S. J1772 does not allow for three phase connection, so it's either ~48A, or not. My guess is they are matching Tesla 11 kW capability, but we don't know for sure. Also, U.S. 11kW, 48A wall charge stations (EVSE) are starting to come available.
