"Are you saying (RIP) that in your case you'd want an OPEN diff?"
Yes. The power of an open diff is the biggest thing the quad motor design is missing, and the reason it is incapable of safeguarding rolling friction.
BINGO! Exactly. Tesla has given a numerous examples, and are about to offer up another one for us; the Tri-motor CT. That is the model I have reserved, but I intend to change that (when they let me) after my experience with the Rivian. Tesla has some pretty good programmers, but I don't...
Sure. The vehicle and computer system could then make an educated guess as to which wheels to put into "freewheel" mode and when.
I wonder, do you think there would ever be a situation where the dynamic changes, and the wheels with the most grip all of a sudden change with it? Oh, let's say...
For those that wonder why the truck is overheating even in very cold weather, a good source of research is the design iterations of the Nissan Leaf. The engineers in that project grossly overestimated how much heat they could dissipate naturally; and that pack was designed to be air cooled; not...
Well, I would refer you back to my original post. The pack is well insulated, and is able to shed very little of the heat generated into the atmosphere naturally. It must be drawn out through the cold plate. Sure, the conditioning system will run more efficiently in this case when it is colder...
Except that in all the instances you refer to, the manufacturer started out conservatively, and ramped up the ability of the vehicle as enough data was gathered.
In this case, the vehicle is overheating during dcfc, so it's the opposite case of all your other examples.
Wow. The only instance I am aware of where this allegedly happened was with a Ford lightning, and it destroyed the vehicle. This is a massive failure of how the system is designed to work, and should really never happen.
That is correct.
On the Ford F-150 Lightning, they fixed an air damn fault issue with an over-the-air update recently. The problems on the air dam are a less-than-optimal system for raising and lowering it.
The less-than-optimal system of course was not corrected with an over-the-air update...
Welp, the purpose of my post was to shed light on why we are seeing the dcfc throttling due to heat. I understand that there are those that want do debate absolutely everything, and cry "misinformation" if there is the slightest challenge to their belief set, but that post was not for those...
Oh. My. "Gravity...?"
🤦
No, it has nothing to do with gravity lol. It has to do with thermal dynamics, but to simplify that, heat rises.
Because heat rises, if you apply a heating Force to a mass, the top of the mass will end up significantly hotter than the base of the mass. Because of these...
That is absolutely true, and one of the critical challenges to pack thermal management. I am actually a fan of the cold plate design for that reason. I am not in their design room to know of any obstacles to adding a 2nd cold plate on top of the upper pack, but I think it would he a way to...
