Electric mining truck creates electric power

Click For Summary

Discussion Overview

The discussion revolves around a fully electric mining truck that utilizes regenerative braking to generate electricity while operating in a mining environment. Participants explore the implications of its design, operational costs, and the limited application of such technology in the mining industry.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant describes the electric mining truck's capability to discharge about 200 kWh of its battery to the grid each night, highlighting its regenerative power generation when descending hills.
  • Another participant emphasizes the limited application of this technology in open-pit mining, suggesting that the operational context restricts its broader use.
  • Concerns are raised regarding the economic viability of operating such equipment, with one participant questioning the profitability of selling excess regenerated energy, which they estimate to be less than $50 per day.
  • A participant humorously comments on the potential costs and the hype surrounding the truck's capabilities, while also expressing fascination with the technology involved.
  • There is a mention of the truck's large battery weight, comparing it to a teenage elephant, which adds a light-hearted tone to the discussion.
  • One participant discusses the concept of regenerative braking in detail, explaining how it allows the truck to generate electricity while braking, although they express skepticism about the media portrayal of the technology.

Areas of Agreement / Disagreement

Participants express a mix of fascination and skepticism regarding the electric mining truck's technology and its economic implications. There is no consensus on the viability or practicality of the truck's application in the mining industry.

Contextual Notes

Participants note the operational limitations and economic factors that may affect the truck's use, including the specific conditions of open-pit mining and the costs associated with running such equipment.

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

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. . . .:DD

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 !

WOW !

CNN said:
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. :oldbiggrin:
