EV?
It is a stupid idea. Period.
Now, if you use a big alternator run by a gasoline or diesel power plant and use electric drive directly to the wheels?
That would work.
They have used it for many years by ore haulers in pit mines. They get work done.
It could even work for Trucks.
The Li-ion batteries are a fire hazard both in cars and in homes. One cell fails? If it has no detector, it is up in smoke and it is next to impossible to put the fire out. I do suspect carbon dioxide extinguishers would work if caught soon enough.
I had a discussion with my local volunteer fire fighters regarding EV fires this past Sunday.
They were all very negative comments.
The other thing they brought up is the Lithium Home batteries being charged by solar panels. Whether they were Tesla Power walls or some other brand.
Frankly, they were all very concerned about the ability for a small volunteer fire depart to ever fight an EV or household battery fire. Which is why IF you have a battery bank being charged by solar panels they should be in a shed SEPARATE from your house. Putting a big lithium battery in your garage attached to your house is just plain STUPID.
