  1. How much would you pay for a range extender.

    I’m not sure how he did this, but I doubt it is good for the health of the battery. I was hoping he would share his install process, what voltage the generator outputted, and how he interfaced it with the car.
  2. 4680 Battery Anode at Giga Berlin

    No, as the structural battery is one of 3 parts put together to make the frame of the car. Even if it is welded, you can cut the welds and reweld it. The guys do it where I work all the time. Not a welder, so I don’t know any more details about how that works, but we use welds in our shot...
  3. 4680 Battery Anode at Giga Berlin

    Looks like those could be coolant ports for sure. However, that metal is pretty thin and it doesn’t look like there is much room for flow. They could also just be mechanical connection points for other parts of the battery.
  4. Looking at Hybrid Supercapacitors

    I can go to any number of old machines where I work and take pictures of capacitors used for frequency modulation (with the associated contactors) but unfortunately my company has a policy where I cannot share said pictures. Even though these machines are from the 50s, 60s, and 70s. You are...
  5. Looking at Hybrid Supercapacitors

    Yeah, thus they didn’t store current, as I said.
  6. Looking at Hybrid Supercapacitors

    Capacitors are usually used for frequency oscillation and control, which is why they are common in filters. Old school frequency modulation was just a bunch of capacitors being switched by contactors. They didnt store or generate current, really, just modified the waveform passing through their...
  7. Did Elon Confirm 350kW Charging For Cybertruck??

    So, even with the 4860 cells, you don’t think they will charge faster than 1C? That would mean that the only reason why you get more MPH with a CT than another Tesla would be because it has a larger battery pack. Charging at more than 1C with currently available cells can lead to cell...
  8. 4860 wild ___ speculation

    CT will be delayed until 4680 cells are ready. They won’t make it without them. Model S Plaid + was supposed to use the 4680 and the fact that it was cancelled does not bode well. I and many others suspect that it was cancelled because they are still having issues producing quality 4680 cells...
