    Is HPC really Roadster specific? I thought it applied to the Model S as well.

    The Model S Options page discusses the "High Power Wall Connector" (HPWC), whereas the Roadster has the HPC ("High Power Connector"). If I've got that wrong, though, let's change it!

    I added some.

    I put in 'Supercharger' to go along with CHAdeMO even though it isn't an acronym.
    Do you guys think it makes sense to have it here, or should we leave it off?

    - - - Updated - - -

    We took to calling the Model S version 'HPC2' for a while. Not sure if Tesla ever called it that themselves though...

    This Roadster page:
    High Power Wall Connector (charging, high power connector, hpc) Tesla Motors
    is titled "High Power Wall Connector", but the URL itself is just "high power connector".
    Further on that page, they refer to it as just the "Home Connector".

    Another Roadster HPWC page:
    High Power Wall Connector | Charging Solutions | Tesla Motors

    So, I don't think HPWC is Model S specific... Rather I think they (somewhat) interchangeably used HPC & HPWC to describe the same thing. And also use HPWC for both Roadster and Model S even though there are two different products designed for those different vehicles.

    Model S charging page:
    Charging Model S | Tesla Motors
    I went ahead and edited and took out mention of HPC for Roadster + HPWC for Model S since I don't think that is a correct description/delineation. With the right adapter, old HPC/HPWC can be used with Model S anyways...


    This is 'weird'... Check out this unfinished page:
    Charging Model S | Tesla Motors

    Nice Job guys!

    Nema references too?

    And maybe link some of the acronyms to wiki sources - thinking CHAdeMO, etc.

    But there is no such corporation -- it's Tesla Motors, Inc.
    The confusion between TM and TMC was actually what launched me on to this project in the first place.

    How about a "slang" category. "Perf" is used a lot and even knowing about the performance car my brain automatically thinks "perforation" and made me think they were ordering a Model S with perforated leather seats! Then Blue Star, White Star, etc could be added just as an area where newbies could learn the various terminology used here.

    No TMI, is what our teenagers use in texting/tweeting = Too Much Information.

    But you probably knew that already. ;)

    HPC2 was a natural extension since Tesla was referring to the Model S UMC as the UMC2.


    Looks like someone has an oil leak.​

    We should probably add P85+ to this list for Model S.

    But my real point for posting is for X...

    For now let's assume the battery sizes are the same as the S.

    X85A? X85D?
    X85AP? X85DP?

    Also, when/if AWD comes to S ...
    S85AP? S85DP?
    S85AP+? S85DP+?

    Note that (AFAIK) (1) "S (non-AWD) Perf" exists but "X non-AWD Perf" won't while (2) "X AWD non-Perf" will exist while "S AWD Non-Perf" might not.

    In the event anyone is still updating the list of acronyms how's about adding MPH (Miles Per Hour of charge)?

    Hi. I made these changes:

    • I merged small tables. When the reader comes here to find an acronym, he doesn't know what category it belongs. He would have to check all small tables. Imagine a foreign language dictionary that separates nouns, adjectives, adverbs and verbs. If you don't know a word, which category do you look at? You wouldn't know. It would be super annoying if you had to check all categories for each word. Therefore dictionaries are not divided into multiple categories. There is a single category. You find the word and then it tells you if it is a noun or verb etc. I followed the same method.
    • I added notes to other editors to the beginning.
    • I removed "PERF". This is not an acronym. Shorter versions of words (example: fab) are not acronyms.
    • I removed "Supercharger". That is not an acronym either. Yes that is a specific term to Tesla but unless somebody changes the title of this wiki to "EV Acronyms and Vocabulary", only acronyms should be on the list I think. If the wiki is renames we could add unique words like "Supercharger", "Vampire Loss" and "Frunk" to a second table below the existing table.
    • I added RHD, LHD, EPA, NEDC, Wh/mi, Wh/km.
    • I added a new column called category to preserve the category information that existed before tables were merged. This way no information is lost.
    • I added borders. Makes it easier to read.

    • Brec, good idea. I've added "SC: Service Center".
    • Most dictionaries have one entry for words with multiple meanings. Following the dictionary method I merged SC, TM, TMC into a single row.
    • Added VIN and REX
    • Added button icons to editor notes on top

    I was reading something on the roadster and don´t know what a PEM is - have only heard of it as a kind of fuel cell which this is obviously not about.

    For fuel cells, PEM is the Proton Exchange Membrane.

    For the Tesla Roadster, PEM stands for Power Electronics Module.
    What is the PEM?

    That should probably be part of this list.

    Looks like the editing instructions are no longer current (possibly not the same since the forum update). From what I can tell, I can only do raw code edit. I could update the raw code, but I think I'll wait for confirmation that this is the only way it can be updated for now (who knows, maybe I'm just missing something).
