Hmmm,

Norway used LESS power in 2020 than it did in 2010. So much for increased consumption due to BEV's.

Probably LED lights saved enough power for the vehicles.

I think it is safe to say heating would be the major contributor to electrical consumption in Norway. If 2010 was a cold year and 2020 a warm year that is the most likely factor.

It would be like driving with your brakes on for half an hour,

It would be convenient though. Arrive with a charged battery etc. We’ll have to wait to see what Rivian comes up with.


ROFLMAO!
And this, folks, is the world some problem actually live in....sweet dreams!

I’m not even going to look it up,but regenerative charging provides only a small fraction of typical charging. It can’t do more than that until those Unicorn Farts actually become real!



I don't know anything about EVs. But logic tells me that in normal driving the regen, even if it put power back in faster than hard acceleration pulled it out, would be a small part of the power demanded for a given trip. Bell, what percentage of the time are you on the whoa pedal? And as you slow the weight the rate of charge decrease.
Now I'm going to trump up some numbers. If instead of slowing a 4,000 lb you are slowing a 40,000 lb combination would you get a faster recharge? And if you think about it very little of the stored power, if any, will be needed to move the EV in a day's travel, why couldn't you finish the day with full charged?

I think some are losing site of the sceenario discussed. This is an Electric vehicle being towed behind a motorhome as a toad. If you do that with a Tesla it will charge the battery until it is full and then stop charging. It will happen pretty fast as regen can generate up to around 100 KW although some documents indicate it is lower at around 77 KW. Lots of videos on you tube have tested this and it works. BUT BUT BUT, with a Tesla the only way to make this happen is if the vehicle is turned on. And with a Tesla there is no on switch. Your butt in the seat turns on the car. If nobody is in the drivers seat it won't happen.

Rivian indicates there electric truck and SUV will be towable four down but don't indicate if regen will be enabled when towing four down. .



Cheers.

Rivian 4 down? Only one I know is Bollinger.

Well, assuming they don't change things they tweeted that it will be four down towable.

I didn't know Bollinger waws as well. That makes two.

Bollinger confirms 4down towing direct in the FAQ. Rivian additional range and flat tow is looking real good. Can't wait for the off-road capability comparisons.

Nice. Still curious to see if either will enable some kind of regen function so one can arrive at end of day with 80 percent...or whatever.

A lot of state and national parks are opening charging stations. I've never understood the haggle over hookups when you have a 45ft motorhome with three A/Cs and a popup next to it with the same overnight fee. So why the haggle over having an EV using a hookup?

Limit it to a trickle charge only. People are towing now with EVs and they'll be looking for charging stations.
