    Gen2 bouncing between 48a and 24a

    I’ve had my gen 2 wall charger since 2016. Never had an issue charging at 48a. Today it suddenly started dropping to 24a for a while then back up to 48a, then back again indefinitely. The breakers are all double bar and I don’t hear any buzzing or anything that seems out of wack. The gen 2...

    Test my 50 amp charger in Toronto, Ontario

    Hi, I just installed a ChargePoint Flex Home Charger and am looking for someone with a Tesla (S, X, or LR 3) to test it at 48 or 50 amps. I have an older EV which is not capable of charging at high amperage. I’m in Etobicoke close to the airport. Please message me privately if you’re willing to...

    Charging amperage limit at home now is 48A?

    While I was in Tesla service (display change) Tesla changed my hood lock and port for upgrade versions as I was told. When I got home I noticed in my scheduled charging that I can set now amperage up to 48A. I could be mistaken, but I think before I had limit 32A. I do not think I really need to...

    2014 S60 Charging Decisions

    Hello! I'm an almost owner of a pre-owned 2014 MS 60 that I've purchase and will be picking up in Orlando soon. It has 41k on it and as I have not spoken with a Delivery Advisor yet, I have no idea whether or not the UMC is in the car and will be included. So I have questions that maybe some...

    Dual Motor Performance - Single On-Board Charger?

    Hello All, My family recently took delivery of a fully-loaded Dual Motor Performance Ludicrous mode X and was amazed to learn that it only came with the standard 48A on-board charger. This was not listed anywhere on the website and there is no factory option to "upgrade" to the dual 72A...

    60A Breaker -> 4 gage or 6 gage wire?

    48/72amp Charger - Longevity, Best Practice, Durability, Failure Rate, etc.

    Saw various reports of the 1st gen charger - or chargers, if equipped - failing. As the 1st generation chargers (40 or 40x2) were replaced with the 2nd generation chargers (48 or 72) earlier this year (I think?), I am seeking information as to how the 2nd generation chargers have held up...

    single charger... unable to pull more than 40A?

    So I may of made an mistake. For the last 3+ years I've been happily using the mobile connector to charge my car. It has worked well and I typically pull 40A at 237V. The car is equipped with the standard single charger. This fully charges the battery during the off-peak evening rates...

    48 amp charger upgradeable after delivery for $1,900

    It looks like rumors that the new 48 amp charger in both Model S and Model X is upgradeable after delivery to 72 amps were true. The cost is $1,900. See the bottom of this image from the current Model S design studio. The same language is on the Model X studio as well.

    Single vs. Dual Charger Poll for Your Future Model X

    Thought we'd take an informal survey of the TMC group here to get everyone's true feelings on the 48A vs. 72A Charger debate. Please indicate whether you would truly need (and I mean real world need, not first world want) 72A charging versus 48A.
