    1) I read that the Tesla supercharger loads 80% in 40min and 100% in 75 min a standard model S, let us say 60kw in 1 hour

    ?ad 1) what are the charging times at 360V or 220V or 110V for the 60kwh

    2) we should load at 90% if we do not use immediately the car

    ?ad2) when Tesla speaks about 75Kwh capacity, they speak about 100% or 90% of the possible total load?

    3) following an empiric feeling , the slowest load is the better load

    ?ad3) is it true?


    thanks - renato

    Yep, that's from Tesla's website.
    A writer for Edmunds also wrote a nice article on a real-world test & measurement of supercharger times.
    2013 Tesla Model S: How Quickly Does a Supercharger Charge?
    There's a nice graph in that article too.
    With the caveat that charging always slows down as you get close to full,[/quote]
    Supercharging, averages 200mph
    For 240v, roughly 18-20 mph
    For 120v, roughly 4mph
    ideally. There are other threads on the forum that discuss the reasons in detail.
    100% of the battery capacity.
    No. Use of fast charging may be a strain on the battery, but higher-voltage charging is more efficient.

    Tesla states that you can charge 170 miles of rated range in 30 minutes. In the real world you get more like 120 based on a lot of experience. If you're planning a trip and time at chargers adds up then you need to think about a number lower than the 170. Think about 35 minutes per stop. From MA to FL it was 12 stops...

      I was reading in the forum that such a trip needed 26 hours instead of 20 with a gasoline car

      I checked the route calculator for a trip here in europe and due to lack of superchargers I am obliged to choose different highways and a 4 hours trip was stated 6.5 hours

      On this video he mentioned about battery degradation after 42k and what he think is the best way to charge the tesla from his experience. Nothing about the speed only about capacity.
      Will be good to get any opinion from someone who charged differently, always to 90-100% if that effect the battery?

        I actually just wrote up my experiences here if you're interested:
        http://teslaliving.net/2016/05/15/5-lessons-long-road-trip/

        Added over 40% to the trip time. Some of that due to my own dumb mistakes.

          I have checked many destination chargers in my area an all but one is for overnight guests only. If i could pay to use them i could take trips off supercharger routes has anyone been able to do this?

          For overnight guests is the "default" settings for participation in the program, Tesla does not require that destination charger participants offer charging for free to the general Tesla public, just for their guests. However, some locations do provide charging to non-guests for free, you just have to ask.

          Thanks. I'm hoping tesla will come up with a program wherein these owners would agree to let any tesla driver charge up for a reasonable fee. My region is devoid of chargers and if I want to drive to Branson 240 miles away I might have to spend the night in Russellville just 90 miles away. Not a feasible trip.

          the plugshare app does this. Individuals can add their 'plug' to the map and permit travelers to stop and charge up. Before the superchargers were filled out, this is what the early Tesla drivers would do.
          I don't think it is common to ask for $ though, but more the user to offer a little donation for the hospitality.

          I read that tesla is in discussions with some service station to install supercharger and that their future goal is to be able to fully charge in 5 minutes. I also read that they have developed special liquid nitrogen filled cables to handle charging rates much higher than 135kv. Has anyone else read more on this matter?

          This is from a bit over three years ago:

          "It's not going to happen in a year from now. It's going to be hard. But I think we can get down to five to 10 minutes," Straubel said in an interview with MIT Technology Review. He noted that the current superchargers, which deliver 120 kilowatts of electricity, "seemed pretty crazy even 10 years ago." Conventional public charging stations deliver well under 10 kilowatts.
