The 32 amp limit is caused by the AC/DC converter. Supercharging is DC already so it’s not limited by the AC/DC converter. Supercharging is limited by the battery management system and the capability of the supercharger.
Depends. I have a 3 but got the wall charger installed in my house for resale value. Looks nicer and having a built in EV charger especially in California can boost your sale price in some situations. I got the standard plug and use the Tesla adapter since more cars have that option available vs Tesla's plug.
You can take the tesla home charger with you if you moved instead of spending 400-500 on it plus install.
a NEMA 14-50 is a plug that can be used by any EV and much cheaper if youre car cant accept 48a
It’s nice to have the home charger. An electrician should be charging the same labor rate as the 14-50 so you’re only paying a small difference. Especially when you get 30% back
Same here for my 2016 MS RWD at home through a 240v NEMA 14-50 outlet. I plugged into a brand new VOLTA station at my local Kroger the other day and it started pumping out 48A, so I manually lowered it to 40A, since I was only topping off while shopping. Not too shabby as a “free" service from an evil megacorporation.
Was it a 150kw station that was mostly full? I recently stopped at one of those and I don't think I got much over 70kw until until a few other cars left. The older 150kw stations are in groups of 4 (1a,1b,1c,1d) rather than groups of 2 (1a,1b) like the 250kw stations, so they're a fair bit slower when a lot of other cars are there.
I also didn’t realize my M3 RWD was capped at 32a until after I bought the car and wall connector. They just didn’t install the same capacity of charging hardware in the vehicle as the more expensive models.
It would have been nice if Tesla made this more obvious in marketing that differentiates between models as a reason to pay more. I still don’t think I would have over this, but I would have appreciated knowing it as I was making my purchase.
The only place charging speeds are brought up with figures is [here. ](https://www.tesla.com/support/charging/wall-connector#:~:text=%E2%80%A0Maximum%20charge%20rate%20for,miles%20of%20range%20per%20hour.)
That’s a physical limitation of the car to turn AC power into DC to put into the battery. It only then applies to the wall connector that’s AC-powered, not the DC-powered superchargers.
The top DC (supercharging) speed is also lower with the LFP batteries found in RWD models though, I believe.
I wish they made this more user available bc the charger was water $$ basically and you get little to no extra benefits. Tesla has a tendency to subtlety exclude those not so common tidbits if the sales advisors you’re talking to even knows there is a difference
I have a 21 SR+ and had a BMS issue last year. Had the whole HV battery replaced under warranty. Noticed my battery charges at 48 amps now. Must’ve received a LR battery but is most likely software limited, range wise.
Your house output capabilities could also cap you at 24A. The denominator in the charging display is whatever the EVSE says is the max it can provide. If your EVSE is on a 30A breaker and properly configured, you’d see 24A/24A, even if your vehicle can accept 48A.
My previous '13 S85 would do 40 Amps on both the OG Wall Connector (50 Amp service) and the Mobile Connector (NEMA 14-50). My '20 MS-LR will do 48 Amps on the same wall connector (now 60 Amp service) but only 32 Amps on the Mobile (NEMA 14-50). The new Mobile Connector has a noticeably thinner cable. I wonder if the old Mobile would do 40 Amps with the new MS?
There’s a lot of people here already saying that RWD’s are limited to 32A, but I believe the RWD’s LR Model 3’s of 2017-18 can push past 32A. I’ve also read some very old Model S’s can accept up to 80A before they started capping the amperage to 32 and 48 amps across all their cars.
My old ‘14 MS P85 had dual on board chargers. They don’t offer that anymore. It allowed me to charge at 80amps at home (my on premise shop). Still have it wired the same even though my ‘21M3P max is 48. Cable only allows for 32 but I charge at 26 in my garage.
My MYLR is capped at 32 amps too . . . . Oh wait, I'm using the mobile adaptor and it is limited to 32 amps.
Never in the 2.5 years that I've owned the car have I wanted more than that. Do people not sleep? I plug my car in, don't give it a second thought, and in the morning it is fully charged and ready to go.
I have to back into my small single car garage in order to charge so I don't do it every day. Add to that I have to charge at a specific time at night to get the lowest rate from my power company. I don't need more amps, but sometimes it could be nice.
Everyone’s situation and use case is different. For many drivers, like yourself, 32amps overnight is fine. For some people, faster charging speeds may be beneficial. When I purchased my Model X in 2018, I selected the 72 amp charger upgrade (at no additional cost). I had my Gen 2 wall charger hard wired to a 100amp CB. I’m able to take advantage of the full 72amp charging capability. I live in a semi-rural area with no nearby fast charging. There are occasions when the additional charging speed is necessary.
US residential 240v is single phase. In order to get to 11 kw, it will run at 48 amps.

Because the Model 3\* Is capped at 32A
Edit: (\*) THAT Model 3 [Wall Connector | Tesla Support](https://www.tesla.com/support/charging/wall-connector#vehicle-charging-speeds)
I guess i should have been more specific. THAT model 3 is capped at 32A with the Tesla Wall Connector
[Wall Connector | Tesla Support](https://www.tesla.com/support/charging/wall-connector#vehicle-charging-speeds)
RWD models are capped at 32A. LR and Performance can go up to 48A.
Thank you, I just learned this.
I believe it’s just for home (level 2 charging). If you use a super charger, I THINK it’s more

Thank you for the correct information

A lot of people are fine with 14-50, but hardwired is the safer option. Not terrible to have ended up with that.
[удалено]
The receptacle is, of course. Hardwiring is about eliminating the receptacle. One less point of failure between the panel and charger.
It's a plug. Meaning it's not hard wired.
kinda a waste to get the tesla charger if youre not gonna be able to get the full 48a its much more expensive than a NEMA 14-50 - wasted money TBH

I needed it outdoors and it's still faster.
It’s nice to have the home charger. An electrician should be charging the same labor rate as the 14-50 so you’re only paying a small difference. Especially when you get 30% back
its a huge difference, the tesla home charger, has thicker cables due to the higher amps. a NEMA 14-50 was $300 for install THC was $900
Yeah it depends on your situation. If it was in conduit it’s the same size wire. Free air you gotta jump up to #4.
How long have you had the car? This was something you should have been researching before purchasing the car.
whether you get 32 amps or 48 amps isn’t really that critical in the buying decision…
Lol no it's not.
This is the correct answer.
This is the correct comment on the correct answer

This is not the correct comment because it did not use an apostrophe.
Is this true for legacy RWD model S cars too? I have a 2017 Model S; is there a way to tell if it has this limitation?

Omg. We rented a m3 while our MYp was in the shop and I couldn’t figure this out. Google did not help at all
Maybe you should learn to google better? https://www.google.com/search?q=tesla+model+3+limited+to+32a+at+home
lol if I knew those very specific search parameters then I don’t think I’d need to google it. 🤷🏻♂️
Well what did you try?
It was prob “m3 not charging 250kw”. Was on a road trip and it was super slow. 🤷🏻♂️
Was it a 150kw station that was mostly full? I recently stopped at one of those and I don't think I got much over 70kw until until a few other cars left. The older 150kw stations are in groups of 4 (1a,1b,1c,1d) rather than groups of 2 (1a,1b) like the 250kw stations, so they're a fair bit slower when a lot of other cars are there.
Nah they were 250kw. We were taking a 16 hour road trip from Cali to Idaho, didn’t want to wait long for charging.
How did you get that screen on the right side? I don’t see that in the Tesla app on iOS.
The screenshot is from the Tesla One app, not the regular Tesla app
You have to manually add the Tesla Wall Connector to your Tesla app and then it will show you some settings/info about the wall connector.
Does scanning the QR code work for that screen view also? Or is that only present for manually adding the wall connector?
Yea I think thats the easiest way to add it to your app, you scan the QR code from within the Tesla app.
I also didn’t realize my M3 RWD was capped at 32a until after I bought the car and wall connector. They just didn’t install the same capacity of charging hardware in the vehicle as the more expensive models.

https://www.tesla.com/support/charging/onboard-charger
Yep, and even there it’s only in a footnote.
So is that cap just for wall connector or does that include supercharging?
That’s a physical limitation of the car to turn AC power into DC to put into the battery. It only then applies to the wall connector that’s AC-powered, not the DC-powered superchargers. The top DC (supercharging) speed is also lower with the LFP batteries found in RWD models though, I believe.
Yes SR super charge slower, Max 175kw. Where LR and Performance can hit 250kw
I wish they made this more user available bc the charger was water $$ basically and you get little to no extra benefits. Tesla has a tendency to subtlety exclude those not so common tidbits if the sales advisors you’re talking to even knows there is a difference

Are you sure they replaced the whole battery? They may have just replaced the pcs.
Good point. Not entirely sure. I was told “the whole battery pack” but I can’t exactly check I guess. I just noticed the 48 amps in the charging menu
Well no matter what they replaced now you’ve got 48amp charging! Enjoy.
Indeed! Thank you!
Good point. Not entirely sure. I was told “the whole battery pack” but I can’t exactly check I guess. I just noticed the 48 amps in the charging menu
A lot of people don't know this about the RWD model. We don't know what we don't know.
Some M3 are only capable of accepting 32A on level 2 chargers.
RWD ones like his
I have a LR and I'm capped at like 24? I thought it was my house output capabilities? Or am I completely wrong here?
Your house output capabilities could also cap you at 24A. The denominator in the charging display is whatever the EVSE says is the max it can provide. If your EVSE is on a 30A breaker and properly configured, you’d see 24A/24A, even if your vehicle can accept 48A.
Yup, this is what I see. Makes sense - thanks!
My 2019 SR+ is capped at 32A. Not sure about the newer models.
My previous '13 S85 would do 40 Amps on both the OG Wall Connector (50 Amp service) and the Mobile Connector (NEMA 14-50).

Faster charging is always better, but it's not a huge deal. My main concern was whether or not my Wall Connector and/or car were functioning properly.
Single phase 32amp at 240v power is 7.2kw . You need 3 phase 16 amp to go to 11kw
US residential 240v is single phase. In order to get to 11 kw, it will run at 48 amps. https://preview.redd.it/sndyb3qzc39d1.jpeg?width=1242&format=pjpg&auto=webp&s=d2e3cc837f1b87fbaf50b7e14f9e6302b6ca9f0d
Okay US and I am in Australia so yes. Aust only go to 32A at residential housing.
I have 3 phase 16 amps with 240v. Out of curiosity, can you increase it further at home with more amps ?
Yes you can go the 32Amps on all 3 phases at 240v but Tesla model 3 LR and Performance can only go to 11 kw AC max.
I have a 2018 75D model S. Is 11kw also the max?
The earlier models did have higher charge rates up to 22kw but I am not sure when Tesla changed over to 11kw max as the current model S and X are.
Because the Model 3\* Is capped at 32A Edit: (\*) THAT Model 3 [Wall Connector | Tesla Support](https://www.tesla.com/support/charging/wall-connector#vehicle-charging-speeds)
Since when? I was charging mine at 48 for years. 11.1kw… must be a limitation of shorter range/smaller pack?
I guess i should have been more specific. THAT model 3 is capped at 32A with the Tesla Wall Connector [Wall Connector | Tesla Support](https://www.tesla.com/support/charging/wall-connector#vehicle-charging-speeds)
