Electric mining truck creates electric power

[jrmichler]

TL;DR

It partially discharges its battery to the grid every night.

A fully electric mining truck has been built that does not burn fuel. It has a 600 kilowatt-hour battery pack, and they need to discharge about 200 KwH of that every night to keep from overcharging it. The secret: It's loaded at the top of the hill, and unloaded at the bottom. The regenerated power is greater than the power needed to drive the unloaded truck back up the hill. A very limited application, but it saves a lot of fuel. Link: https://techxplore.com/news/2019-08-jumbo-electric-vehicle-energy-bragging.html

Veerrryyyy limited. https://www.google.com/search?q=ope...ome..69i57.18721j0j7&sourceid=chrome&ie=UTF-8

It must be expensive running equipment like that for less than 24 hours per day, to earn less than $50 selling the excess regenerated energy.

Lol. . . I would think so. .

Some of the hype-type journalism wasn't to bad though. . . .

Jumbo electric vehicle has energy bragging rights at no charge.

The all-electric beast is powered by a 4.4-tonne battery – about the weight of a teenage elephant.

I can only relate to "Jumbo Jets" or "Olympic-Size Swimming Pools". . . . This is really interesting. . . definitely pushing technology !

powered by a 4.5-ton all-electric battery.

WOW !

Through a process called regenerative braking, the eDumper's electric motor goes into reverse when the driver hits the brake pads, releasing electricity that can be stored and returned to the battery.

Amazing stuff. . .! . They didn't hype this though. . . lol

Not a problem, just add 45 of these SuperBrightLeds light bars and you are good to go.

The ultimate macho manly truck light bar setup. Ten kilowatts and 1,000,000 lumens should be enough for anybody.
