Starting @ £2500, no reserve and no feed back, he mentions he is open to offers of £12500.
I like how they're specifically mentioning ultra rapid (150kW+) chargers, and they mentioned hubs somewhere else in the article
At this rate NI is going to go from the worst to the best charging network on the island
While their original plans included many of the slower AC destination chargers, the company recently told us it has become clear that people are mostly interested in DC charging. That has resulted in a revised project that will now have a greater emphasis on Rapid and Ultra-Rapid sites.
That makes it sound like they're going to shift toward DC provision, £50 million to roll out DC chargers in the North is 2.5 times the eCars investment (€10m+€10m) that supports the Irish eCars network.
Interesting, although some more details would be nice
Haven't used Monta myself but there seems to be an option to list your home charger as a publicly available charger and charge money
I might try to make some money from the Zappi then 😂
Good to see.
Maybe not, "Geodetic measurements show ongoing topographic uplift at rates of up to about 2.5 mm per year in the North, Western and Central Alps, and at ~1 mm per year in the Eastern and South-Western Alps" (Wiki)
A bit of a stretch saying that it will never need recharging...Eventually the stored weight/energy built up at a height will be gone😉
There's a lot of space to fit a lot of batteries 😁
I shudder to think what the consumption would be like, electric trucks are up around 100kWh/100km (or 1Wh/m if you prefer 😉) so I wouldn't be surprised if those big dumper trucks are 10 times that
However they only seem to travel a few kilometres at a time, so it's possible something like a 200kWh battery would do a full run. Plus then a charge while loading and you're ready to go again
There's also a lot of smaller mining vehicles which are probably much easier to electrify. A lot of them are pretty slow moving so you might not need batteries at all. I saw an electric excavator a whole back which basically had a big cable drum on the back and was hooked up to the site electricity grid
And remember that giant bucket wheel coal digging/Germany destroying excavator which is powered by electricity
Hence why they are using fully autonomous trucks on a lot of mine sites in Aus, particularly in the iron ore mines in the north west. There is also a large gold mine in the south of WA where plans are underway for conversion of their autonomous vehicles to electric power.
Catepillar released its first battery electric large mining truck last year (I think this was reported before?)
There is also a number of large scale electric conversion projects for 70 Series Landcruisers and Hilux utility vehicles (or 'utes' in Oz!) dedicated for the mining industry, with the support of Toyota. Testing has been going on for sometime and
The example Andy is referring to is the opposite. The quarry is on the top and is transporting the load downhill. I was pretty sure you've heard about it
So this is the one I had seen, and yes it drives down the mountain fully loaded…
Yes but these trucks go downhill empty and uphill fully loaded, the battery would be empty within a few metres. Obviously a truck of that weight wouldn't freewheel, they aren't that difficult to drive in reality just extremely boring doing the same repetitive route.
There's more to it than that🫣
Just use g=-9.81 m/s^2 and you're grand.
There was one electric dumpster truck that was fully laden going down a hill and empty on the way up and actually gained enough energy from regen to power it's way back up the hill
That was more down to an accident of geography, it was servicing a quarry up a mountain or something
So unless we can somehow conveniently teleport all mineral deposits to the tops of hill then it's probably not a widely applicable solution
Having said that, I imagine the brakes on those yolks get a lot of work so you'd probably get some serious amount of energy back from regen.
And unlike trucks there's no real advantage to not using regen and gliding down the hill since you're stopping at the bottom anyway. Plus I'm not sure I'd ever want to work with the guy who tries freewheeling one of those dumper trucks down a winding dirt path in a quarry or mine
Completely defying the laws of physics... Empty truck going downhill uses the same amount of energy as a fully laden truck going uphill, my applied maths lecturer was wrong all this time as was Issac Newton.
After 20 years them machines are not just scrapped after that, they are too valuable to do that.
They are brought back to the main frame and rebuilt/reconditioned, roll out as new again.
I would not say this is a dumb Irish company. They are linked to electric classic cars in Wales who convert classic cars to electric and have a 3 year waiting list. They have an team in enniskerry working on EVs, so they should at least be able to understand the problems.
That said the sums don't line up. It may be a trial, I expect they will link up with suppliers of a kit suitable to power the unit, as in a battery, motor and inverter/ charger.
The source article mentions a contract to convert 8,500 vehicles for €50 million, which is a few thousand per vehicle
The debate is whether that's a mistake, or the first in a series of payments, or if the "electric vehicle" isn't really an electric vehicle
Personally I'd be expecting something closer to several hundred thousand per vehicle. If the expected service life is 20 years, then it's possible the vehicles for conversion are already at the end of their life
That would make sense because as long as you can come in a good bit cheaper than the cost of a new vehicle then conversion is the better option
3.5-5 mil is that the price of the conversion?
Them machines are expensive.
Could be 100k for a single tyre.
Also a lot of the loading diggers/shovels/dragline things are run on a tethered electric cable.
Aarron Witt has a YouTube channel if anyone is interested in that sort of equipment
Apparently those big hybrid mega dumpster trucks regen the whole way down into the pit, which puts most of if not all of the juice back into them to get them back up out of the pit/mine…
Yeah they're a bit ambiguous on how they define the conversion. So I'm worried you might be right that it's the giant dumper truck version of a mild hybrid
First link is diesel, 2nd is diesel electric, nearly same horse power/kW in each @ 2600 kW, I cannot see anything more than a token sized battery going into them.
3.5 to 5 million dollars each, 20 year life span.
I think that's trains, although it's quite possible that some mining vehicles are also diesel electric or some diesel hybrid
If that's the case then it would make any conversion a lot simpler, just slap some batteries and charging system instead of the diesel engine
Aren't some of these big machines sort of electric driven to begin with, with the diesel engine basically being a generator for electric motors? So the conversion could be replacing the diesel engine and driving existing electric motors?
It's some deal alright, I'm guessing it's more like an initial investment, for example the €50 million is to setup the conversion facility. Or it's €50 million for the initial batch
There are manufacturers getting on board with electrification of construction vehicles
It's probably worth remembering that the usual economics of conversion versus replacement are different here. Heavy equipment like this isn't exactly mass produced and is probably kept going to 20-30 years because it's cheaper to fix it than replace it
So an electric conversion would then make much more economic sense in this case, particularly if you got an insanely good deal out of some dumb Irish company who didn't price the work correctly
If there was a market for these vehicles would the manufacturer not be making them, there was only one big truck I remember reading about, it went uphill empty and came down hill with a load, with regen it produced more than it needed, I would imagine a very niche application in a hand full of mine sites.
The guy is full of it, figures are all wrong, some of these trucks would be assembled at the mine, not ship them here to Wicklow for a refit, look at the size of the wheels, look at the ladder just to get on the bloody thing. Why is it that collision avoidance can only be fitted to electrics, afraid of running over the saved penguins and polar bears that will over populate the earth?
It just occurred to me, it going to be hybrid, 1.4 kWh battery and a small motor bolted on somewhere.
It doesn’t seem plausible by any stretch.
You wouldn’t buy the motor for that not to mind everything else and labour etc.
Theres a zero missing or it only includes labour or something.
The good ole Bam pricing method is alive and well😡
That works out at about €5,882 per vehicle…. Fair play to them if they can do it at that price….
I’d give them my 3 Series to convert for that price!!
