It's an excellent idea to help with range loss in very cold climates. Nice work! I love the ingenuity!

âžThis is killer! I have thought about doing this as well, as we've installed a few on boats. Kudos on the mod.
It's amazing look at cabin temp vs exterior temp 0 loss to range I'm doing 320wh/km which is typically better than my summer drivingIt's an excellent idea to help with range loss in very cold climates. Nice work! I love the ingenuity!
What was the source of this chart? What does "capacity" represent? Why isn't up to 100% at any temperature?Typical EV battery temp vs capacity curve:

Sure, preconditioning mitigates this initially, but on a long trip, battery power will be used to keep the battery comfy.
It costs me less to travel in freezing Temps with the heater than without. I can also dcfc way faster with it, saving money in canada because our dcfc charge by the minuteIf the diesel heater heated both battery and cabin to say 60 degrees F., would the Lightning have nearly the same range as it would if the ambient outside temperature is 60 degrees? Perhaps the one gallon of diesel used by this heater is better on the environment than driving in freezing temps using the Lightning as it is??
I wouldn't do it to my truck and lose the warranty, but if Ford did it, it would be great.

I would like to read more about this topic.
+1 on the schematic. I'd really like to see how the install actually integrates!Do you have a coolant schematic that includes the heater and battery loop? Or did you just climb under there and follow the lines?
If the battery needs to be cooled you'd probably want to turn the heater offWhat happens if the truck decides that the battery needs to be cooled? I've seen some speculation that there's a valve that unifies the battery and cabin loops when the battery needs to be cooled. Obviously it would be bad to heat the coolant in that situation....
Yeah, that is exactly why I asked. I know that's tongue in cheek, but that's exactly what I *don't* want to have to do. I'm not interested in installing anything in the truck that requires the operator to do some specific unusual thing to prevent damage. It needs to "just work" so that I don't have to worry about it being done incorrectly when it's not me driving.If the battery needs to be cooled you'd probably want to turn the heater off
I'd recommend watching the Munro teardown, they did a really great video showing the system and its nuance!
Hey I got a webasto glycall heater so if the truck is turned off and the battery decides to heat it will aid the heater in heating the battery. It's fantastic at dcfc because it will heat the battery almost 50% faster. The coolint in temperature is only +20 of the battery temp so it doesn't get to hot. So if battery temp is at 0 the coolant temp will be at 20. Where normally it's +15 without the diesel heater. I spliced in right at the heater core. The hose I spliced into I purchased new ones to bring back to stock if I need to. Next year I'm going to remove everything and permanently mount it in the battery Co.partment. and the diesel tank in the box.Responding over here instead of in your new thread, because I don't want to encourage thread proliferation about this...
I'm extremely interested in this modification. I'm hoping you can answer some burning questions...
Can you share what model heater you chose and why?
How did you decide where to splice it in?
Do you have a coolant schematic that includes the heater and battery loop? Or did you just climb under there and follow the lines?
Do you have a max tow package?

What's your plan for a safe and permanent mounting of the tank?
Besides the obvious not-an-EV, my Powerboost didn't drive nearly as smoothly as my Lightning. Or as lazy, with Blue Cruise, which I seriously love for freeway driving. But it did have 500 miles of range on a full tank, which was pretty awesome on the backroads of Wyoming last summer.I mean...this kind of solves the issue of range degradation in the winter months, while sipping on the fuel and giving you close to normal battery range, no?
Buying a Powerboost would only benefit OP in the winter and come Spring/Summer/Fall would be back to paying an arm and a leg to fuel it.
