Electric VehiclesThey argue that trucks need massive batteries for towing. And so they should include them.
I'd offer a counter argument that range extenders should a standardized option. A modular box in the bed that you can add a number of 40lb batteries to. That way you can buy and carry however much range as you may need.
I concur, because the fact is that 80%of tricks arejust glorified minivans and never tow a trailer. But the batteries are the limiting and expensive part so if you put huge batteries in every truck then you can only make half the trucks you could make otherwise.
The truck featured in the article offers the larger battery pack as an option at the time of purchase. It’s not mandatory. They sell standard, extended, and max range versions.
I wonder if truck manufacturers could standardize on a battery extender connection, so that RV and other trailer manufacturers could put batteries in the RV/Trailer that the car could tap into.
I would argue a better solution is more and faster charging.
Then you're still stopping every hour, or every 60-80 miles. Even if it's for a 2min charge, that gets annoying.
The issue is that towing a brick through the air kills range. It's a fact that can't really be avoided. You just need more storage to over come.
Another option is to put batteries in the trailer. I thought of that for long haul trucks.
60-80 miles!? What kind of vehicle are you talking about? Towing a trailer can vary quite a bit but it's generally ~50% of normal range. So in a 300 mile vehicle, that's 150 miles, or 2.5 hours of driving.
This article is shit. I tow 9,000lbs fine in my EV and get about 1.25mi / kW.
The charging infrastructure does, indeed, suck. 10000%. But that's America. With careful planning I'm not stopping for more than 20-30 minutes which gives me time to get snacks, stretch, and use a bathroom.
In my own use, I'm never towing further than needing to stop 1-2 times so it's fine.
Did you read the article?
You should read the article.
This article is shit
I don't need to read the article to know how far an EV will go while towing, I have first and second-hand experience. I have a friend who uses their Lightning to tow boats on a daily basis.
Okay then. Let me summarize.
100 to 0% gets you 300 miles.
Peak charge speeds are only 10-80%.
Headwinds matter a lot. Stay above 20% for safety.
Now your only have 60% of your battery available for each leg.
That 300miles is now 180.
Half that is 90miles. Best case.
Real world? Yah, 60-80 miles available between charges.
Peak charge speeds are only 10-80%
-
Peak charge rates vary by vehicle, but most are <10%
-
You may have missed that we were discussing faster charging speeds.
Headwinds matter a lot. Stay above 20% for safety
Any decent trip planner is going to account for headwinds. The 10% arrival accounts for margins of error in those calculations.
From the article:
Our first trailer got about 1.0 miles/kWh towing at 65 mph (our ABRP reference figure). When we swapped to the 7,000-pound inTech, our efficiency dropped down to 0.9 miles/kWh. If you are doing the math at home, 0.9 miles/kWh means a 130 kWh battery pack (the standard “extended range” packs you find in trucks like the F-150 Lightning or Rivian R1T) will give you about 117 miles of total range from 100% to completely dead. A Tesla Cybertruck’s 123 kWh battery does a few miles less.
But out in the real world, you never drive from 100% to 0%.
If you had read the article, you'd also have second hand experience that 80 miles is the appropriate real-world range for towing RVs.
That is absolutely incorrect. I have towed 9,000lbs numerous times and yielded 225-250mi of range.
I will agree that the Ford Lightning and Cybertruck are garbage though.
If you had read my comment, you'd know that I have lived this experience, and no, it isn't.
