Are we on the brink of an electric car revolution?

eDumper: World’s Largest Electric Vehicle Never Has To Be Recharged

As the heavy transport descends with more than double the weight, the trucks regenerative braking system recaptures all the energy it will need to refill the charge that it will need to use on the way back up again. Regenerative braking allows the eDumper to produce more energy downhill than it consumes uphill.

Really? Haha.

I really think he has really lost it with this styling. It is meant to be bought compete directly with the Ford F150 which is sold by the millions to US small c conservative working men.

They wouldn't be seen dead in that. (Nor would I, for different reasons)

I get your point but I think what they did not explain is that it's route is down hill while loaded (and hence needing a lot of braking) and uphill empty going back for the next load. That would work moving rock down from a mountain top quarry to a processing crusher below but of course would not hauling from the bottom of a pit mine up to a plant on the top of the rim. With losses and efficiencies I have to doubt it both ways and just chalk it up to the enthusiasm of the author.

My Electric car weighs about 1500Kg. It uses about 0.25KWh to move a mile on level ground at reasonable speed.

If the car was converted to a truck with a payload of 3000Kg, then the gravitational potential energy gained by descending 100M in altitude is approx. 0.8Kwh. If we assume that the car itself has 100% efficient regenerative braking then we can ignore the weight of car itself when driving back up the hill. If the distance traveled to descend that 100M is 1 mile (about 7% gradient) then the regenerative braking downhill provides more than enough energy to drive the empty car back up the hill.

So the numbers are entirely plausible that the giant truck never needs to be charged back up.

I can see this but they aren't factoring in all the energy used loading the vehicle at the top of the slope. Also I suspect not all it's journeys are going to be similar to this, at some point it's going to be used to take rock from the bottom of a quarry, then it will need to be re-charged.

Trucks don't load themselves. They just park where wanted and a loader or some other machine fills the bed. A common set up is to park a large excavator on the blasted rock pile so the operator can look down into the beds of the trucks so they can be loaded so the load will slide out easily. With giant purpose built ledge trucks such as this one that is not a concern and they will just use the humongous loader shown. The picture doesn't show make or model number but it appears to be in the class of the Cat 988K which can have up to a 17 cubic yard bucket on it.

I think the point about the dump ruck is that most quarries and mines are below ground so in only a few cases will the truck not need to be recharged. In most cases there will be some advantage in having the regenerative breaking but it will only be a small contribution to the energy use of the vehicle.

Regarding the Tesla truck, appearance, which appears to be a function of the design and the bending moment diagram for a beam, aside, in the UK a truck such as that would be used typically by a builder or farmer who would have it parked most of the day while he was working so it could be charging. Long distance driving would not feature in its use pattern much in the UK although US driving patterns might differ. The low speed torque of an electric motor is what gives it the advantage over a Porsche or a Ford truck. The Porsche would probably beat the Tesla on top speed though and certainly on range.

Looks very "futuristic" and the ballistic part of the show could appeal to those like myself who are members of facebook groups concerned with van break ins and security. On the other hand that futuristic shape lacks the practicalities that most builders want . Builders want a box that will hold 8 x4 sheets of plywood or plasterboard.

My son-in law put down the $100 to pre order a cyber truck. I'm giving it very serious consideration and have managed to get my wife to consider it a Christmas present she doesn't have to shop for or wrap.
The idea that we might someday drive two of them into my small town and park them side by side amuses me. They are going to need a good charging station in the middle of New Jersey for us to get between Vermont and Maryland. (500 miles).

Anybody care to wager how long it is until the first EV battery blows up/ goes on fire/ melts down whilst being fast charged? I don't want to be near it!
