Redacted post by Martin from FB:
***Martin Rebuilds Tow Rig Update / Charge While Driving News***

TLDR
- In short:
-Charge while driving works

Some of you know me know and know I am huge Ford and particularly Lightning fan. I run Martin Rebuilds and host the Tech Charged podcast with Christopher Bowe and Jace Craft-Miller. Over the last couple years I've have several Lightnings at the shop and have clocked nearly 100k miles towing all over the nation and Canada. The Lightning is hands down the best towing truck (under 10k lbs) I have ever owned. This is coming from owning multiple brands and sizes of every truck made and I still stand behind my belief that the Lightning is the best. In fact, we just bought a "new to us" 23 ER Lariat max tow for the shop but a change is needed.

Charge While Driving News - As some of you know, I have been working with Zachary Scott Carpenter and Patrick Cheung on a generator that can charge the Lightning while driving down the road. Last week Zach had a very successful test logging over 700 miles running a Ford branded generator while running down the highway at 70mph. It was able to move the efficiency from 1.8 mi/kwh to an impressive 2.3 mi/kwh adding 50 miles of range out of a measly 7kw ford mobile charger. With a much larger generator we expect to nearly double the Lightnings range. See the chart below for what to expect at different speeds and generator sizes.

Genset test upside - The range added will only be limited by 2 factors, 1. How much generator you put in. 2. How big the on board charger in the Lightning is. The 2022 and 2023 Lightning have 80 amp charging so you will see up to 19kw added which means over 500 miles of range. The 2024+ Lightning has 48 amp charging so we expect to see 350 miles of range.

Genset test downside - In the interest of honesty and transparency, which is the core value of my YouTube Channel, the biggest downside I have with the generator is the noise level. To be fair, we tested this with a really loud generator and a lot can be done to quiet these things down. Inverter generators are much quieter and sound proofing can be added to reduce the noise.

My Take on Range Extending - With the shop getting more busy, increasing the volume of towing coupled with several long distance vacations a year, the need for a longer distance tow rig is real. For me, the best 2 things about the lightning are the quiet cabin and the incredible power. Those 2 things are THE reasons I have stayed with the lightning for so long. With that said, my opinion is adding a generator to the truck takes away from the Lightning experience so we have decided to change our tow rig. Instead of trying to add a generator to the Lightning or range extending it, we are going to a larger battery truck.

--------------------------------------------------------------------------------------------------------------------------------------
I am Zach the electrical engineer talked about in this post and I met Martin in Joplin the day after this test:


I just got back to Tulsa and put almost 1000mi on my truck driving while charging @ 7kW.

I am not as concerned with the noise as Martin suddenly was when he took a drive with me, but I AM 100% positive that an inverter generator with sound attenuation is a must for this project. We're still not sure how we'll release this to the public, what will be included, what we'll be selling, or what generator we'll be doing the final testing with, but I have ordered this generator:
https://www.lowes.com/pd/Westinghou...ane-Natural-Gas-Inverter-Generator/5016661947

I am also proceeding with programming many features like auto generator start/stop based on speed, modification/real time calculation of the GoM, generator fuel level reporting on the infotainment screen, full control to configure the charging rate at all times, and more. I should have more updates this weekend and more testing.

Please don't clog this thread up with stupid comments and/or safety Karen worries. Martin and I are both engineers and will fully test every aspect of this mod before we release anything to the community. I want this to be a technical brainstorming discussion and hear some other's perspectives. Martin can get on here and post his range extending estimation spreadsheet soon. Thanks, ~Zach

SUPER COOL!!

Seriously, I'm astounded Ford has not patented a charging "trailer" connector that would allow the truck to charge from an external source. If one could rent a generator, or use one on your trailer, it would go a LONG ways towards alleviating range anxiety.


For the interested, with an efficiency of around 2.0mi/kwh at 70mph, and 10.5kw charging (my charging rate with my 48a charger)

1️⃣ Power draw at 70 mph without charger

  • Efficiency: 2.0 mi/kWh
  • Energy use: 70÷2.0=35 kW70 \div 2.0 = 35 \, \text{kW}70÷2.0=35kW

2️⃣ Net battery drain with charger

  • Charger output: 10.5 kW
  • Net battery draw: 35−10.5=24.5 kW35 - 10.5 = 24.5 \, \text{kW}35−10.5=24.5kW

3️⃣ Effective battery efficiency

  • 70÷24.5≈2.86 mi/kWh (battery-derived)70 \div 24.5 \approx 2.86 \, \text{mi/kWh (battery-derived)}70÷24.5≈2.86mi/kWh (battery-derived)

4️⃣ New range

  • Battery capacity: 131 kWh
  • Range: 131×2.86≈374 miles131 \times 2.86 \approx 374 \, \text{miles}131×2.86≈374miles


✅ Result: Range improves from ~262 mi to ~374 mi → about +112 miles extra range.

If towing, and getting an efficiency of say 1.0 and charging at 19kw (~80a charger).

1️⃣ Power draw at 70 mph towing

  • 1.0 mi/kWh → 70 kW draw

2️⃣ Net battery drain with charger
70−19=51 kW70 - 19 = 51 \, \text{kW}70−19=51kW
3️⃣ Effective battery efficiency
70÷51≈1.37 mi/kWh (battery-derived)70 \div 51 \approx 1.37 \, \text{mi/kWh (battery-derived)}70÷51≈1.37mi/kWh (battery-derived)
4️⃣ New range
131×1.37≈179 miles131 \times 1.37 \approx 179 \, \text{miles}131×1.37≈179miles

✅ Result while towing:


  • Without charger: ~131 miles range
  • With 19 kW charging while driving: ~179 miles range
  • Gain: +48 miles

And since chat GPT was being so handy, it made a chart of towing range gain with various charger inputs.

I have often wonder what is possible with these trucks, but I have very limited knowledge of electricity! I always wondered if you could add an alternator or generator onto some type of wheel to generate electricity. I remember reading this many years ago and always remember strange things:

Sorry if this is stupid, but it just shows my lack of knowledge in this area. Good luck with your project and keep us updated.

I've been wondering about this very scenario since they first announced they were making an ev truck, very exciting and honestly, you're saving me from having to lift that heavy gen I have into the back of the truck lol.

Looking forward to your results.

Might want to do some research before making that claim...

I've talked to Martin. It's a great idea. I've often thought about taking a generator with us when we go on vacation to places that don't have a 40-50 amp plug in for charging at night. I've also played around with the thought of an actual battery too. Either way, Pioneers like ya'll are awesome! I love this!

Cute and inefficient because it uses petroleum?
Inefficient because generators are wickedly expensive to run. I did some math on this when I got my truck, I called it a hillbilly hybrid, I guess if range at any cost is a thing ...

Stop at a fast charger and have Lobster instead of cheap burger 🦞

If this is truly accomplished, I’m intrigued. The video shows nothing of value, though. It’s just a generator charging a truck while the truck is parked. Show us the view from a go-pro on the side of the vehicle showing the EVSE plugged in while driving, that will at least begin to be believable.

I have zero interest in a gas generator.

I’d install ~120 kWh of additional battery into a camping trailer and use that to charge while on the road. Install a CCS1 charge controller into the trailer and I can DCFC charge both at once when there are enough open stalls or from the truck’s Pro Power while the truck is charging.
