EV towing range effect

[Trace26]

Interesting video on how towing effects EV range.

Obviously, the dead flat wall that I put on the front of my trailer is going to have a more dramatic effect on consumption than something with a more sculpted aerodynamic shape, like a cargo trailer or a camper.

Obviously he hasn't looks at camper aerodynamics very closely... At least not the ones made for full-size truck towing.

Aside from the clickbait thumbnail though, it's really a well-done, informative, and entertaining piece.

Came here to post this video. It provides a great breakout of the strengths and weaknesses of EV truck use. They may not be for everyone, but for a lot of us they make great sense. The last test of 0-70-0 with load was fascinating- the truck with a load used less net energy than the unloaded truck. If you are on the fence about an EV, give it a watch.

My personal Towing experience.

Towing 3 tiers of scaffold with my MachE 100 miles on small open Uhaul trailer cost me $20, $5 for the electricity @12pennies/kw, $15 for the uHaul.

Same trip in my truck a Chevy w 351 v8 costs $28 in 8 gallons of no ethanol fuel not to mention the truck has no Air.

If we make the trip 200miles, Chevy truck cost me $56 in fuel and would do it non stop.

I would have to stop at about 105 miles to charge the MachE. Take on 45 to 50kw at a Tesla supercharger at 42 pennies a KW, $21 for $42 for the trip but the charge time would be 40 minutes before dropping and picking up the trailer is figured in as very few EV chargers are pull thru.

I would expect similar range from the Slate with it a big battery. However I could possibly get the scaffold into the bed of the slate and get the unladen range and only pay $2.50 per 100 miles.

I've towed my boat with my Ariya. I get about half my normal range while towing. This is similar, IME, to what happens to gas mileage in a non-EV (e.g. my old Honda Pilot) when towing. The biggest difference is that gas stations are everywhere, but fast chargers are still relatively rare once one gets away from major interstate routes.

His doing the math on how much public charging doesn't save makes it even more baffling how perpetually full, and often with a wait, the local T-bag charging stations are.

One thing he wasn't able to get to, is showing that EV range also drops more than gas range when towing. Regenerative braking means EV are at the most efficient with cyclic loading, where as gas are at the most efficient under continuous load. So even more than those results show, when towing a large (8'x10' front) slab-sided box for any real distances, EV's still have a long way to go.

Consider that even a brand-new (actual 20+mpg unloaded) gas Silverado as a dedicated tow pig plus a Slate as a runabout, would actually have a combined cost (and weight) of less than the Max Range Silverado EV. Things that make you go hmm...

You make a good point, though some would argue that extra insurance cost, etc etc etc for 2 vs 1 vehicle. The numbers need to make sense, which I agree with.

Factoring in the economic value of time spent (or saved) is always a wise idea.

There you go again, @AZFox, using your fancy rich-man's world view of the opportunity cost of time spent charging. Jeez. I'm sure that there are some Gen Z types that would "raw dog" a long charging session...just because!

I can't tell if this is sarcasm or not 😅

100% sarcasm. If you know what "raw dogging" (like on a long international flight) is, this might refer to you?

Had to look it up, haven't heard that term before. Guess that means I'm old now.

Or not quite old enough to have Millennials/Gen Z/A/whatever kids who look at TikTok as a source of social trends and/or cosmic truth.

I'm surprised Slate hasn't leaned into that one. With crank windows, no radio, you're raw doggin' every trip.

It's always fun to see Raw Dogging from that Seinfeld Episode or random other older stuff gain traction again. You never know what is all of a sudden get rediscovered. All of a sudden this week my instagram feed has starting fill with clips from the 2012 kids show "Daniel Tiger's Neighborhood" with full comment sections of people hating on the main character LOL.

That's probably it, my oldest is 3 and tiktok is blacklisted on our home wifi. haha
