Feds plan to melt ICE

Can you "Siphon" from one EV to another with the equivalent of EV jumper cables?
Not at all well. For obvious reasons, dc charging at hundreds of volts is blocked by safeties. Hooking the 12v together could work to charge the dead 12v but doesn't charge the hv battery. You could plug in a charger to a 2kw inverter. Fastest way by far is a tow. Use regenerative braking on dead car and it charges fast. Something like 10km of range for every km towed.

The pickup trucks that have relatively high-powered 240V AC outlets can be connected to the Level 2 AC charger of any other EV. (For that matter, you can do it with the 120V AC outlet and charger, too, but it's going to be much slower.)

Direct DC connection of the batteries is not possible, because they all have different nominal DC voltages.

Not to mention the potential ridiculous currents. We've all seen how hot 12v jumper cables can get, scale that up to hundreds of volts and thousands of cells in parallel and it gets dangerous.

I usually take three people with me. Standard load is 5 bikes in the trailer, we often have six. Plus gear, spare fuel and usually some beer.

That said, for your scenario, something like a Ford Lightning would still need 6-7 stops for a probable minimum 2 hours apiece total - provided that the fast charging station is available and unused. So, 12-14 hours minimum just for charging time. That would roughly double the time it takes us to get there - with 4 times as many people and almost double the number of bikes. And let's not forget, the high speed chargers aren't free.

This type of application is something for which current EVs are not practical - and it's why the action by the feds concerns light-duty vehicles only. Plug-in hybrid like what Ram has announced would work.

Ford Lightning charging stops shouldn't take 2 hours. Proper technique is to charge to no more than 80% each time unless you absolutely have to. More stops, but shorter, ends up taking less time. Ford says the 131kWh battery pack takes 41 minutes from 15% to 80%.

The Silverado EV will do much, much better in this application.

It takes just as long or longer for that last 20% as it does the first 80%. Sure you can add 30% more stops if you want. Now you're up to 10+ stops of around an hour. So you'll save 2 hours and some battery life (it harms them mildly every time you fill them to full capacity) but you'll be that much more annoyed. Like I said we stop 4 times for 15-20 minutes apiece in my truck for that trip down to the states, just long enough to get a bathroom break, snacks or meal, some fresh diesel and the last stop is semi-optional, more for convenience than anything else. We arrive at the rental house with all the fuel we'll need during the week if we take the truck in for supplies and the occasional restaurant trip. Still not comparable even though we're towing much more, carrying three extra goons and extra bikes.

Repeat: Silverado EV will do much better than Lightning. Longer range when towing (by a lot) and capable of fully utilising a 350kW fast-charger. YES it will still need more stops than the diesel would, but it's within the realm of being doable. What's your trailer weigh and what's the height and width? The one TFL towed was a pretty big barn door. Theirs was legal-max width and 7 ft high.

When towing trailers, GM's choice to put the charge port at the left rear, instead of the left or right front, is a real pain, until pull-through charging stations become common ... and I have yet to see one. Same issue with Tesla, by the way.
 
My trailer is 21' long. About 9 feet tall at a guess (you can stand up in the trailer), 8 feet wide (maximum legal) and dual axle with a capacity of 6,000 pounds. The floor and walls are 3/4" plywood and as you would expect, it has indeed had a vehicle inside it without trouble. Weight is a guess but somewhere around 4,000lbs-4,500lbs. All that plywood and the heavy steel chassis weigh a lot. It's a barn door and then some.

That’s a big ask of any vehicle to drag that with any efficiency. I’d be out shopping for a Kenworth 4dr low chassis . Just keep the GVW under a D licence if that was possible.

That’s a not a story , bought it , sorted it out quite easily, drives around . Didn’t do his homework first ( that’s on him) and found a solution.
And it’s Yellowknife .

The trailer that TFL towed was probably close to the same frontal area, and weighed 6500 lbs loaded. (Car hauler)
My trailer with five bikes and beer/gear in it is about 7,000lbs loaded. As I pointed out above, it has the underpinnings to carry 6,000lbs of load which means I could put a light duty truck in it (and the previous owner did). A sixth bike doesn't seem to add much to the mileage requirement.

My experience with enclosed trailers is highway mileage is not affected much by weight. You aren't using a ton of hp accelerating the weight and aero drag on the highway is huge. When I used to pull trailers for a buddy, his tandem enclosed snowmobile trailer took far more gas to pull than a tandem axle dump trailer that was probably 4x the weight. I am actually surprised that some manufacturer or vendor hasn't sold tail flaps or tents to make the back of the recreational trailer a cone. On one trip, you may save enough fuel to pay for the device. Only set it up for long runs as it isn't worth the time on a short pull. They have them for tractor trailers.

That isn't surprising. Rental cars at the airport are, for now, a terrible EV application. People are getting into them who haven't dealt with an EV before, into an area with unfamiliar EV charging infrastructure, plus all the charging-network and payment headaches. That's a recipe for trouble. I wouldn't want to deal with it, and I have an EV.

In the future world where EV charging is as common and easy as filling stations, that's when this changes.
 

Federal Govt's EV Policies demands are ridiculously unrealistic - Auto Association leadership.​



 
Instead of saying "why we can't", instead ask "how can we".

My engineering career involved plenty of "how can we". Yes, sometimes there was "well, this won't work, but this other approach will", but progress forward was always the objective. Sitting still, or moving backwards, is never a long term option.

Words to live by: if you're going to be a naysayer, you'd better have a darn good alternative that's better than what you're bellyachin' about.

Those guys are sadly entrenched with the 50% of US Buick dealers that decided to close instead of selling ev's, 50% of Ford dealers opted out of ev's, etc. Like soccer players throwing a tantrum when they dont get to do exactly what they want, when they want.
