Home Charger Recommendation?

[mutant9]

Yeah looking for one for the gravity as wheel. Want to make sure it has NACS. Did the autel maxi you mentioned above have NACS?

 

[segbrk]

Grizzl-E Ultimate is another solid 80A option if you can ignore the fact that they named the version with NACS "Cyber."

 

[Bill AGT]

Yes, my Autel is NACS. It has been great. Have a 2025 which does NOT come with a charger so I used my $650 rebate for the travel charger

Picking up my gravity Tuesday. Thoughts on the standard Tesla wall charger vs the universal wall charger? Gravity will be my only EV do don't see the value of having ccs connection at home.

 

[johnse]

It's not a CCS connection at home. CCS is specifically the DC connector.

J1772 is the AC L1/L2 connector.

We have two Universal Connectors. My Tesla (and future Gravity) use the NACS cable. The Mach-E uses the built-in adapter. It's a very nice adapter!

There are a lot of cars out there with J1772 ports. Have any friends that may want a charge while at your place?

Personally, I don't see the need to have a 100 A circuit unless you deplete your battery every day. Certainly not if you need a panel upgrade to have enough power available. 50 or 60 is plenty.

My X can use up to 72 A (on a 90A breaker). I think I encountered one 80A destination charger in 7years.

 

[Ron_Burgundy]

If I were installing a brand new charger, I’d get 80A - if I also didn’t need a new panel.

However, I have a Rivian and 60A wall charger, so I will just use the NACS adapter for the Gravity. It charges so quickly on 60A/48A anyway.

If they ever do have V2H, I will get the necessary charger - but not going to get it now.

So I've seen several threads about this and I'm still a little confused. I have an original Tesla Home Charge from when I bought the M3 in 2018. Will this work without any mods with the Gravity? (I thought I saw a bunch of talk about having to change the wattage or something in the original Tesla chargers. Hope it's compatible as-is.)

You will probably be ok as-is. Based on a 2018 installation date, you almost certainly have a Tesla Generation 2 wall connector. Check the breaker size on your Tesla wall connector circuit. Since your Model 3 will charge at a maximum of 48 amps, I would expect it was installed on a 60 amp (or less) circuit. If that is the case, you should be OK without any changes.
If your wall connector is on a 100 amp circuit, you will probably need to get the internal switches in the wall connector adjusted. The people on this forum who had problems with the Generation 2 Tesla wall connectors had them on 100 amp circuits. Those required changes to the internal switch settings.

I have an 80A Tesla wall connector. They no longer make them though, and it's probably been close to a decade since Tesla made cars that support 80A from an AC connection. There might be some for sale on the used market, or even a new one that somebody never got around to installing. They can also be set to 40A or anything else, so if you get one and want to change the wiring at a later date, it's a matter of opening it up and changing a setting.

I have it wired for 40A because I can't imagine a scenario where I will take a road trip, come back with a nearly depleted battery, and need more than 320 miles of range the next day after an eight hour charge. But anybody who has that need has the option of a faster charging station.

Thanks for the info! I'm pretty sure I have a 60amp circuit. (Not at the house now.) Hope it just works as I have to add a new one in a 2nd location...it'd be nice to only buy 1 more. ;-)

should work, if it's not working, then just open the cover (shutdown circuit first), and lower the amp settings. super straight forward.

I'll just stick with my 5yo Grizzl-E Classic. It's "only" 40A, that I have dialed down to 24A. I really have no need for faster home charging. Also safer, just in case.

Home charging is a perfect case for "bigger isn't always better".

We all have to know our limitations

Yeah, I think my in-laws had that. They were one of the first owners down here of a model X in 2016 and they had a gen 2 to wall charger installed and I believe it was 80 A both charger and car.

 

[Andretex]

I have two chargers. Lucid charger that is great as it goes to 80A. and I also have the ChargePoint Home Flex. cheaper and works great. i love them both but the chargepoint has a nice app, which makes it much better to use.

Charging speed question. I’ve watched a bunch of charge videos for Gravity, but most focus on high speed charging. If I have a 60A charge, which effectively charged at 48A, how many miles can I accept to get per hour when charging my Gravity?

My R1S is pretty “meh” at 21 miles/hour with 11.1kw….

48A * 240V *0.003 miles/Wh or about 35 miles per hour real range. Gravity may display a more optimistic EPA-efficiency based number.

That’s what I was thinking but my wife’s old Y got 42 miles/hour of range in same circuit, and I feel like Gravity is more efficient.

Did it get that, or just report that? Miles per hour is a very imprecise measurement that depends on the accuracy of the efficiency figure used in the calculation. Just look at kW delivered to the car. There's no arguing about how much energy it represents.

FWIW I'd expect Gravity to be more efficient than the Model X, but not necessarily more efficient than the Model Y - a smaller, lighter vehicle.

It actually did get 42 miles of range per hour. Great points in efficiency. X gets about 35. I know that’s now a great measurement, but it’s “real world” to me and easier to understand for the wife…not that she’s not smart, but as soon as I begin explaining, her eyes glaze over n
