I have looked numerous times for the 500A CCS limit in specifications. As far as I can tell, it doesn't exist. The whole handshake exists to figure this out. The 600kW-1.2MW charging demos are using 600-900A. Unfortunately, adapters were not part of the spec (including J3400) so there's no...

There's so much engineering and chemistry that goes into it, and I don't have the clarity to describe it. So here's a paper that goes into a partial analysis: https://www.jetir.org/papers/JETIR2509154.pdf Using this as an example, let's explore the battery configurations. And if we arrange...

The CT is a great example of why cell chemistry matters far more than voltage. It sucks regardless. If that much heat was lost in the bus bars on the packs, why aren't' those liquid cooled? Cooling is only applied to the cells themselves. But anyway, I'm not going to convince you. Moving on...

Sure. And we both say it's negligible within the battery pack itself. The cells see the same current each at a given power level regardless of pack configuration. The energy lost between charger, cable, port, bus bars, and battery cells (as heat) is 7-10% in a DCFC session. So even if we...

That doesn't contradict the statements. From Michelin: https://www.michelin.com.ph/auto/advice/tire-basics/rolling-resistance

800V does not change the thermals of the battery pack in a meaningful way. It only impacts the thermals of the charging equipment and the cables. I don't have the patience/clarity to explain it, but here's Peter Rawlinson of Lucid explaining that it's a myth: Lucid (and Hyundai/Kia) uses...

Hm. Maybe I need to beef up my logic in that section. My point is that The R2 can gain just as much charging improvment with better battery chemistry/cooling above 40% as it can using the existing batteries and charging at 800V. The problem isn't the voltage, it's the cheap batteries. The iX3...

I've done a fair bit of towing and have never experienced anything like this. Absolutely open a service ticket. There's either a battery issue, a cooling issue, or a massive software bug. This is well within the expected use case of the R1S. It's not normal regardless of temperatures (unless...

This exactly. While it can be patronizing to get a LLM response, you disbelieve the robot that has a far broader "knowledge" than any human in the world? What is your rationale or evidence dismiss it? Clue us in. As a tire nerd (both cars and bikes), the explanation is *perfectly* accurate.

I did a deep dive on page 3 of the State of Charge 10-80% charging thread, but someone suggested I put some of the deep dive here in a separate thread. This is *not* comprehensive, despite the length. I will update this top post with relevant points based on any comments I get as I get time to...

I don't have any evidence or data to prove it, but it makes sense to me that heavier wheels and tires see larger efficiency losses when riding over real terrain, especially on rough surfaces. Each impact imparts vibration into the system, and with more mass, more energy gets absorbed into the...

Yeah, the timing is too suspicious... I think there's a software limit based on input current. Could bea limitation of the wiring at the charging port? To add on to your supercharger comment - All (but 14) current "V4" superchargers are V3 cabinets with V4 posts. They *should* be able to easily...

I would not bet against it, but yes, the math falls apart at the extremes. I can regularly get over 3mi/kWh on my R1T around town in good weather. And lots of the reviewers seemed to see 4+. I think it's plausible. As an example... On the recent Bolt Ionna trip, they needed to make it 341mi...

Tracks the EPA dynomometer coefficients pretty well, though falling more aggressively with speed, which makes sense given the shape and the lack of the EPA data to account for anything over ~75mph. 21” R2 65 mph: ~300 miles vs 292mi 70 mph: ~255 miles vs 264mi 75 mph: ~225 miles vs 240mi 20”...

Haha, I'll add that as a PR. There's a checkbox to allow you to set your own colors.
