But wouldn't that regenerative running create a pretty large drag on the tow vehicle? I mean it's part of the braking system isn't it?
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.
