  1. Cybertruck gets 11,000 lbs tow rating / 2,500 lbs payload (official) + "shatter-resistant glass"

    Most recent "leak from trusted source" that you should take with a huge grain of salt is 350 miles and 122 kWh, who know if that is gross or usable This puts it's efficiency a bit worse than R1T Enduro Max Pack (if the above is right), but practically the same, 345 Wh/mi vs 348 Wh/mi

  2. Rivian Max Pack EPA Data (document shows 141-142 kWh usable battery)

    Why? It's the EPA rating, not "I'm driving at 80 mph at -35°" rating

  3. Rivian Max Pack EPA Data (document shows 141-142 kWh usable battery)

    Really interesting, 141.8 kWh usable and 410 miles on EPA 5 cycle, meaning 346 Wh/mi or 2.89 mi/kWh, quite impressive

  4. Rivian Max Pack EPA Data (document shows 141-142 kWh usable battery)

    Yes, those coefficients are supplied by the manufacturer

  5. Cybertruck gets 11,000 lbs tow rating / 2,500 lbs payload (official) + "shatter-resistant glass"

    No I'm not, they said in many instances impact resistance and all that, which didn't go too well lol, but still held up But not that the glass was bullet proof, they did say that about the body

  6. Cybertruck gets 11,000 lbs tow rating / 2,500 lbs payload (official) + "shatter-resistant glass"

    The glass was never said to be bullet proof, just the body

  7. Max Pack 1 - 100% Charging Curve/Speed - R1T

    It was expected since the way the achieve it is more energy dense cells instead of more cells In most cases, energy density and charging time are opposites when compared in cells that the fundamental are close to each other

  8. Good to have a CEO who isn't tanking the brand... [CLOSED DUE TO POLITICS]

    Why? Because Rivian has an amazing product and I love seeing what everyone is doing with theirs, and would also love to have one one day also Specially the off road and camping trails with gorgeous photography some members post

  9. Good to have a CEO who isn't tanking the brand... [CLOSED DUE TO POLITICS]

    I will give a small suggestion, that everyone should take for every scenario in life, go look at the source instead of reading an article or news reel of "someone said something"

  10. Cybertruck has a usable range of 266 miles? 🤔

    Well, I will leave you with your confidently incorrect numbers then

  11. Cybertruck has a usable range of 266 miles? 🤔

    You are switching units, but your math is right in this example but you are doing it with the wrong numbers with the data from the Cybertruck screen Battery energy is kWh, Power is kW A 75 kWh battery being drained at a rate of 50 kW will last 1.5 hours

  12. Cybertruck has a usable range of 266 miles? 🤔

    No, 77 kW is the instantaneous charging power, 75 mi/hr is the instantaneous range added rate, which is Tesla is charging power divided by EPA rating The 50 kWh is how much energy has been added in the charging session so far, but since we don't know what SoC it started, we can't do anything...

  13. Cybertruck has a usable range of 266 miles? 🤔

    Your math is wrong, and once we do it right it shows that those number are likely placeholders All those reading in Tesla are instantaneous, so charging at 77 kW and 75 mi/h would mean that with 77 kWh, it would go 75 miles, which would mean 1.02 kWh/mi, which is obviously wrong unless it was...

  14. Cybertruck has a usable range of 266 miles? 🤔

    The cables on V4 are rated for 1000 V and 615 A at 100% duty, so 615 kW, and use the 1000 V NACS plug V3s are rated per the image above to 1000 V only in Europe with the CCS2 connector, the North America ones are rated at 500 V

  15. Cybertruck has a usable range of 266 miles? 🤔

    Some of those numbers doesn't make sense For example, 77 kW and adding 75 mi/h means 1020 Wh/mi rated, which is obviously wrong Also, Tesla rounds up or down the percentages, so it could be anywhere between 71.5 and 70.5 to 65.5 and 64.5, so best case scenario 5% for 16 miles for 320 miles...

  16. Max Pack Battery Capacity Confirmed - 149kWh

    I would say in part, likely would have to restrict the peak power a bit, plus the low range increase that would make it a even worse deal If Rivian does the smart thing, they would fit smaller Rivian motors on each wheel, don't need 2x the dual motor setup, but that goes against cost savings...

  17. Max Pack Battery Capacity Confirmed - 149kWh

    Sure, first, I'm not battery expert, but work with them and designed and tested my fair share of packs on my career so far, so anyone feel free to correct me There is a few things you need to balance, electrode and current collector thickness (by the way, this is one of the places the tabless...

  18. Max Pack Battery Capacity Confirmed - 149kWh

    Just some hard numbers going from the cells for the Large Pack On Munro teardown you can clearly see the Large Pack uses Samsung INR21700-50G cells, each is 17.787 Wh, with 7776 cells, the large pack is 138.31 kWh gross If they use LG INR21700-M58T the Max Pack, each is 20.4 Wh, resulting in...

  19. Yikes! Overheating motors.

    This is completely wrong Without getting to technical, the way they do it is to change the phase of the magnetic field such as it's not in its optimal position for efficient torque production, so for the same wheel torque the total current increases. The input power increases for the same...

  20. Tesla to sell $100m worth of Superchargers to BP

    And they are actually designed as it's own product, instead of the mess of cobbled together third party parts which most other chargers are
