    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.

    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

      More like “never has to stop working to charge”. It is novel that its charging mechanism operates as a function of doing its primary job.

        Not novel. I think there was a train somewhere in Africa, that transported some ore from mountain to port. On the way down with ore it charged and uphill it used charge.

          Is novel for a dump truck to use this. Of course it’s not a completely new concept entirely.

          That’s genius. Who cares if thermodynamics wins, it weighs less on the way up so works out just fine.

          Just like the example in TFA.

      Reminds me of some guy with a OneWheel that was saying he’d never charged his board in like a thousand miles as his daily commuter.

      He lives near the top of a mountain lift, so he takes it home and just runs on pure regen lol.

        So he’s just breaking? What a silly thing to claim. I bet he’s not even regening a lot. When i ride up a mountain until my battery is down to 40% or so and ride down i regenerate around 1% or something. It might even be in the 0.6% or something

    “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.

      Well yes but it does also recharge itself by going downhill while loaded and storing power from regenerative brakes. Then it drops the load and has enough charge to drive back up. The power is coming from it being loaded at the top.

        I know how it works. I was making a joke by applying the concept of disposable e-waste junk to a massive dump truck.

          Yes but your comment was in every way indistinguishable from a comment by an idiot who had no idea how it worked, didn’t read the article, and commented an incorrect explanation anyways.

            You truly believe someone thought that you would just throw away an entire dump truck when the battery died?

              Depends on how easy it is to remove the battery and how many replacement batteries are on the market.

              Also a bit of a ship of theseus issue where if the truck gets refurbished by the company then is it the same truck?

              These things are very large and very few in number. I know nothing about the company behind its production.

              So it is possible.

      Pretty sure its also not solar. The machine gets loaded with weight at the top of the hill, its regenerative brakes store power on the way down, it drops the load off, and the lightened machine stored enough charge to drive back up.

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

      Yeah another clickbait headline. It’s getting recharged all the time, it’s just very lucky to be in a use case where it goes down hills with large loads all the time

        It’s more than a clickbait headline, the first paragraph is just flat out wrong:

        Perhaps best of all, it consumes no energy doing it.

        Obviously it’s consuming energy going uphill. Just because the power source is gravity doesn’t mean it’s not consuming energy.

        hahaha guess it boils down to that 😂

        but I was specifically wondering if they built the vehicle with a charger and ended up never using it, to their own surprise. or if they knew they’d (almost) never have to charge it

          Must have a cable somewhere as a backup otherwise you’d need a full battery replacement should it ever be discharged.

      Gonna go ahead and guess that when designing a 110 ton mega dump truck things are probably pretty front loaded on the planning side of things.

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

    I read the story.

    I saw the comments on the story

    I laughed at the pedantic slapfights happening in the comments.

    I came here to comment on the neat story and poke fun at the silliness, to find the same pedantic slapfights here.

    Sigh.
