Reefers will have Def and DPF next year.

Almost everything I've read is saying 1 hour recharge will give 400 miles. Where are you getting all of your information from?

 

Half hour was the claim. Maybe 10 hours to be 100% 500 miles. Don't know that.

 

At first thought it could work well, but after thinking about it I'm not so sure. If engineers could figure out how to install electric generators on the trailer hubs, I'm not certain they would bbq produce enough power for the reefer unit. I'm also wondering how much extra drag they would produce. Would there be enough extra drag to cause a drop in mpg's?

 

Being home with the flu, I have been googling all this info on the buck roger truck and all I can say is, dream on! Mega chargers, solar chargers, 1 hour charge to go 500 miles (yet the car takes 9?).
I have to give Elon credit, he could sell ice to a Eskimo!
How much will this new infrastructure costs? How much will it costs to park and charge up?
By the way, we topped 10 million barrel a day production in the US today. The Diesel engine ain’t going away.

 

Honestly, this would work well for LTL operations that run 200 miles out n back. This way they are always back at a terminal to charge. I don't see this being an otr or even a regional option in my life time.

 

Exactly.
And will be more suited for inter city delivery, like the six wheeler delivery trucks.
By the way, anyone look closely at that truck? How the hell do you get out of the cab in a emergency? The door is behind the seat!

 

It sounds like Elon Musk gave you the flu, too.

 

No. Most diesel reefer that I have seen have connectors or terminals that will allow rapid connection of electrical power to operate the unit. You don't see them hooked up that way often, but there are a few places that have power cable stations for reefer trailers.

 

The tractor engine would have to produce enough power to replace the power generated by the diesel reefer engine. Not insignificant, but the tractor engine has the benefit of economy of scale.

Generators in hubs or axles are what electric cars use, and trains as well. They could easily supply the required power. Thats not to say there wouldn't be any design hurdles, but there's no hard physics limits that would stop it from working.

 

Your describing perpetual motion, it doesn’t work. The Diesel engine on a locomotive is turning a on demand generator that provides electricity to the electric motors on the drive wheels.
A Diesel engine on a refer has to turn the compressor which requires most of the horsepower, along with turning the fans, the alternator.
