World's largest EV never has to be recharged

The dump truck, at 45 tons, ascends the 13-percent grade and takes on 65 tons of ore. With more than double the weight going back down the hill, the beast's regenerative braking system recaptures more than enough energy to refill the charge the eDumper used going up.

Amateurs.

The 1963 Černý Důl – Kunčice nad Labem aerial ropeway is over 8 km (5 mi) long, over 30 m high in places and carries 135 tons of limestone every hour from a quarry to the nearest train station. Its 120kW 3-phase synchronous motor requires power for a few minutes at the start and end of each day when most of the 800kg-capacity trolleys are empty, and spends most of the shift generating mains electricity and acting as a speed governor. Unlike the EV, it is fully autonomous most of the way, only 5 people are required to operate it including loading and unloading. The quarry will continue operation as long as it pays off, then the ropeway will be scrapped (projected 2033). A dude illegally rode the way up on it somewhat recently.

EV never has to be recharged... Because it recharges on the way downhill.

"World's largest EV never has to be plugged in" is sufficiently click-baity without being so dumbly self contradicting

"World's largest EV"

Blatantly untrue. Larger EVs have been in use for more than a century at this point in the form of EMU trains.

yes it does. just going by the numbers posted operating in the space it does results in a net loss of12% battery each trip.

You just toss it when the battery dies and get a new one.

Click bait that actually makes me glad I clicked???

Wow what a great use case.

I cannot avoid to be pedantic on this, it is recharged during half the trip… it just does not require plug-like recharging

well that was unexpected

I'm curious if the desgin team knew about it in advance

Till elon finds out that if he manages to cover the sun, he can charge us on sunscription

Cool EV bruh, but can the horn make a fart noise?

"EDumper" is a great name for a dump truck.

Very cool! It's a pretty specialized use case, but still awesome to see.

2017

At 50 tons and 700 kilowatt-hours, this truck is the biggest EV in the world Each round trip will generate 10kWh of spare electricity for the grid.

Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae.

I hope OpenTTD devs consider adding gravity-based electric transportation of heavy loads as an option

Very interesting use case but kind of dependant on this very specific setup? I feel like an even more efficient and low maintenance method would be like... a ramp.

Does it discharge extra energy into anything else? Does it burn off extra energy as heat to maintain regenerative braking?

Stupid title. It recharges every trip.

I'm no phycisist but I'd bet that the claim "it consumes no energy" is almost certainly false. I get what they mean but this isn't exactly a honest way to describe it.

Oh cool they're using the same principle the guys at Edison are using for their logging trucks on a much larger scale

Esisyphus

I have a strange feeling that this isn't exactly true

This is very fucking cool.

No one commenting on the fact that the first paragraph says it doesn't even CONSUME energy????

A 600 kwh battery pack so... Rocks can roll down hill? Galaxy brain moment.

They must be hauling the load downhill, what about the ones that hauls the load up from an open-pit mine?

Back in my day we drove back and forth to work uphill, both ways, and we only lost weight because we could never afford enough Starbucks and avocado toast!
