Read some of the other threads he created and it will be very clear why he is getting this response.

This sounds similar to my experience in the R1T. However, most of the time my phone's Google Maps route and car route are identical, down to the estimated arrival time. I consistently use both because I like the speed trap warning and reporting on the phone. I hope Rivian adds that soon. I...

I think white wheels on a Storm Blue truck with a wrapped white top could look very cool. I have been thinking about getting 20s so I can properly air down for beach driving. Also considering painting the 20" steelies white. Your post definitely helps me get an idea of what they could look...

That's not how it works. At a low SoC when the charging speed is the fastest, the battery is less than 750V, in the ix3, anyway. (It will spend less time below 800V in a Lucid Air GT, because that is a 900V pack.) You can see that when the ix3 was charging the fastest, current exceeded 500...

True, but when charging at 300-400 kW, which is what you (and I, BTW) want to do, even with a 800V platform you will exceed the rating on the adapters. You don't buy a 800V vehicle to charge at 240 kW.

If you watch the video I believe the current exceeded 500 amps for a period of time.

I just watched a OOS video and they tested the ix3 charging performance. Guess what? The 800V pack hit 59C. Unusually hot. :CWL:

It seems like you are moving the goal posts. Of course properly heating and cooling the battery pack makes a difference in battery stress. But there is no reason why you can't properly cool a 400V pack. The cells are not under more stress just because it is a 400V pack, as you originally...

I am watching your progress! Let us know how it goes.

As a EE, you should know that a typical NMC cell in a pack is 4.2V when fully charged. A LFP cell is typically 3.6V fully charged. The stress on the cells are not any different based on how they are arranged, if you charge each cell at the same rate. Right? The "V" in your formula is max 4.2 V...

When I upgrade my Gen2 to a Gen3 with 180 kWh pack and 800V charging (LOL) I plan to order it with the Range wheels. I agree with you and want the longest range possible on the highway.

An aftermarket company did just that for the original 20" OEM wheels. And from reports on this forum, the efficiency improvement due to aerodynamics was not obvious. Air currents are hard to predict, and sometimes something that looks more aerodynamic isn't. That said, I personally think the...

My R1T is my second EV and I love it. I think your Ram is bigger, but I have never found the bed in my T to be too small. I easily moved three mattresses with the tailgate down earlier this week. Performance is stupid - so fast and it almost drives like a sports car. And I can drive it on the...

I have the same experience with traffic on my commute to DC. I know the logic: regen cannot make up for acceleration loss. And steady state speed with coasting is more efficient. Except that is not what I have seen in my Mach-e or R1T. I'm fact, I tried coasting in my Mach-e with almost no...

@Thebandit is correct. Charging current is limited by either the EVSE or the vehicle. The EVSE cannot supply more than the vehicle accepts, and the vehicle cannot demand more than the EVSE is able to supply. In the real world this means you can set the current limit on the EVSE, or the vehicle...
