So RegGuheert, which prize are you going to opt for, the expired Wendy's Baconator coupon or 20% of some forum member's net worth?
I think the Baconator coupon could be a better deal ;-)Boomer23 said:So RegGuheert, which prize are you going to opt for, the expired Wendy's Baconator coupon or 20% of some forum member's net worth?
Super cool! Thanks for posting. Perhaps REMA should have sent a team to help you study this very impressive plug design. I always wondered if Tesla coated the pins with silver. To me, that would be about the only material that made sense for this type of application.TonyWilliams said:See the lining in the socket of the lower power pin? I don't have a very good picture of the center coaxial pin in the socket. It's made out of a different material than the socket, which is likely a copper alloy.

IEC 604463) Green with Yellow strip - apparently how the Chinese make a green ground/earth wire

Parallel 12AWG (~3.5mm^2) surely are only rated to 60A (30A each), continuous (AFAIK)?
And silver, or unobtanium/whatever, with a contact resistance of a couple of mOhm (which would be remarkably low for any connector system after a few hundred insertions) would still result in I^2R heating of 150 W!

I wouldn't be surprised if they used two smaller wires per conductor in the supercharger cable the same as they do with their UMC to help keep things flexible. 280A seems low for 120 kW - the Tesla pack maxes out around 410V IIRC, so 280A would only be 115 kW max.donald said:This is exactly what I said to the tech guy answering questions about the car, seeing as the lead from the plug was of much the same thickness you'd get for a L2 6.6kW charger (and may well have been a bundle of 12 AWG lines).drees said:Imagine you have two of those sitting side-by-side - not to mention the ground.

He just shrugged and repeated '280A', as if I should not even be thinking to argue that Tesla was so superior it was able to ignore the laws of physics.
All a matter of opinon - there's 4 different dash material options - piano black, obeche wood, lacewood and carbon fiber - the obeche wood is available in both gloss and matte finishes.donald said:The version I saw had material on the dashboard that I was told was 'a wood finish'. It looked more like a piece of old drift wood, with a rough appearance!! Very strange choice of material - I guess Elon likes it

smkettner said:Like the 20kW home charging... 250v x 80a = 20kW but where do you get 250 volts?
I think the Elon marketing team just likes to talk in round numbers.
palmermd said:I'm also not certain whether the 120kW supercharger will really do anything for the car. Each supercharger feeds two plugs. The supercharger splits the power between the two cars if there are two connected. As the full vehicle tapers, the less full one is allowed to pull more, but if they both want full power it will be split at 45kW each. I believe that the 120kW supercharger just allows for 60kW to be sent to each car thus making the station faster at filling multiple cars, but the cars don't really draw any more since the speed is governed by the cars BMS. It could be that the cars would allow more than 90kW and it could benefit with the 120kW capacity, but I've not seen any posting directly stating this.
This might explain why the cable is rated at 90kW max while the station is rated at 120kW.

Thanks. Good to know. By the way, if the pack is nearly fully discharged, how long will it stay at 120kW?

A forum member who lives in the desert has told me he has never seen his Model-S activate battery cooling while unplugged, and he has only seen it activate battery cooling while plugged-in twice. His location regularly gets over 100 F in the summer.sparky said:A surprise to me too.Stoaty said:So if your Model S is off, but plugged in to charge the TMS doesn't run to keep the battery at optimal temperature? That would be a surprise to me.
It's off and plugged in and sitting there after being charged to 80%. At times when I enter the garage, I hear what sounds like A/C running. I don't think that's just computers and I don't understand Franck's comment.
I consider the losses from computers etc. the real vampire loss. I don't consider the loss from the BMS activating to cool or warm the pack "vampire". Also, I expect the pack energy lost due to cooling to be very small. But, we'll see when the FW update arrives.
