I think the big issue with going all in for 800V is the lack of 800V charging stations. Having the ability to charge off of 400V and 800V stations would be more logical.

If they won't provide a way to upgrade their battery packs, then I won't buy one. We already have to make a lot of compromises by buying an electric vehicle, and if I have to live with those compromises for the life of the vehicle, then I it doesn't make sense for me to buy one until those...

Something like this is all you need. https://www.etrailer.com/Trailer-Brake-Controller/Hayes/HA100400C.html?feed=npn&gclid=Cj0KCQjw3s_4BRDPARIsAJsyoLO2Z9-BBXeEIKqSmMBUBo5-N085niz9B_XmDIhA-adChhIQ6kVWXJkaAn4iEALw_wcB

An electric brake controller is probably all that you would need. I am sure Rivian has looked into how to make it very compatible with current brake controllers. If you could use the Rivian to slow your RV, especially on long downhill runs, you could get a lot of recharging of the battery.

No, that is not how diesel electric trains work at all.

Yeah, I am going to have 800W of solar, and I think I can squeeze in another 2 100W panels. But if they laid out the roof with some consideration for solar, I could probably have 1800W easily. And yeah, installed batteries are 1.2kWh of useable energy. That might last one cold night of...

I really hope Rivian includes a 30 amp plug for powering RV's. Although I am building a system on my RV that won't require that much amperage since I am installing four Tesla modules and an inverter. I should be able to run the AC for 10 hours straight with no sun available. With sun, I...

Ideally you would use the Rivian regenerative breaking to slow down and maintain speed going down hills. If your RV and the Rivian weigh 10,000kG together, then the energy needed to slow you down from 55mph would be around 1kWh. So, you wouldn't want to charge the vehicle while being towed...

C has absolutely nothing to do with the ampere-hour rating of the battery. Nothing you said changes that fact.

That doesn't change the ampere hour rating of the battery. If you discharge the battery a 3C you get 690 amps for 20 minutes which is the exact same thing as 230Ah.

We already new what C was. But now that DunRider told you what it was, you are now trying to explain it back to us? You said "C is the capacity of the battery in ampere hours." Which is 100% categorically wrong. A 100kWH battery can have a C rating of 1. A 50Wh battery can have a C rating...

This is absolutely correct. C is definitely NOT the capacity of the battery in units of ampere-hours.

Actually, it would be free energy. Instead of using the friction brakes of the towing vehicle, you could use the Rivian regen braking to slow both vehicles and recharge the battery for free. You could almost recharge completely coming down something like the Ike.

Full width of 8.5 ft and full height of 13.5 feet at 11,000 pounds. I did the math to see if I could use a Rivian to tow a light weight tiny home. The range at 55mph is 103 miles with the 180kWh battery. If you had something in which the height was reduced to half, you would get around 146...

The weight of the trailer has a much smaller impact on range than its size. At 55mph, the aerodynamic drag of a large trailer uses about 3 times the energy compared to the rilling resistance. At 70mph drag is 4.5 times greater.

If they can get a 6,000 pound tow rating out of the rally car, plus a 30 amp plug in for an RV, I would be sold.

What to do? I think the Rally car is more my style. Should I wait for it, or get the Truck when it becomes available. What a first world problem!

I think they has a we-gonna-take-your-money-and-run tech.

200kWh battery and 700 mile range is 285 watts per mile which is almost the same as a Tesla Model 3 AWD (283). If they had some realistic numbers, they might fool more people.

I do like that color!
