Hi All
I came across this again and thought I might share it with the group.
https://www.tuffaustralia.com.au/worst-hotspots-for-roadkill-in-australia-revealed-rival
Cheers
Has there been an increase in the number of roadkill as this news story says? August is already over. They wrote that a 15% increase was expected.

John Cadogan has done a couple of very well-reasoned bits on this exact aspect of the EV truck debate. Highlights include the hobbled payloads such vehicles would have due to the massive battery packs required, the eyewateringly expensive and power hungry nature of a charger network that would come close to keeping such a fleet moving across our land, and increased numbers of drivers required due to the sheer number of hours added to shifts by charging wait times, to name a few.
To quote him loosely, EV tech doesn't scale well for that application, and that's before you consider manpower obstacles. Apart from the above at least, you're all set... providing you can get a hold of enough minerals to build a profitable fleet and swap out the aging, constantly-cycling batteries.
Sometimes you just gotta shake your head.
The battery packs must be very big. Very big. The efficiency of such a truck will not be very high, so there will be increased costs. And this will all affect the cost of other products. No, electric trucks are not going to become popular anytime soon. Unless a very energy efficient battery is invented.

HEAT
when we work our vehicles hard -eg towing we use auto trans coolers to dissipate heat.
with electric vehicles working hard there is going to be heat issues also- how do we cool that?
there is a lot of heat generated on charging batteries particularly on fast charge (and high discharge also).
heat and electricity go hand in hand but are also enemies!

I haven't seen an electric/battery powered semi, B-double or even a small Pantech yet.
One mining company claims to be going electric with their giant dump trucks, but they don't stray far from base ................ at a speed of about 40 kph.
18 wheeler doing 1,000km overnight Sydney-Brisbane? I don't think so, cars are no where near that yet.
And the payload would be seriously diminished to allow for the tonnage of batteries on board.
Re-charging? I dunno, maybe 12 hours.
Before this post goes ballistic I would suggest we leave sex, politics and religion out, of all things Isuzu.
In closing, I would like to say ............... batteries are gay!

That's probably because some bureaucrats with no spine will sell their version of the grid "faster, better and cheaper" to get elected and endup costing 10 times as much to the taxpayer in the end 
Where have we seen that before? What's that, NBN? Hold your beer?

Hey, I'd love to see it. Who wouldn't love having all the torque available immediately in their off-roading tow donkey?
Infrastructure and batteries are the biggest impediments I can see. As you say, diesel is here to stay for a long time yet, and anyone avoiding diesel out of fear that electric is going to somehow kill their investment is kidding themselves.

Well we can only hope the progress into a viable solution.
IMHO diesel is here to stay for quite awhile, think road trains and the likes.
But it wouldn't hurt at all if you could get 500 Ks from an EV while fully loaded.
Darwin to Alice is about 1500 Ks, we usually do it in two hops: Spend some time in Mataranka overnight and next day midday refuel at Tennant Creek.
That should be feasible if they come up with an EV system that will do the distances.

I just deleted an obscene amount of text, because it was becoming a bit of a rant.
In short, as far as I'm concerned, batteries will be neither good enough nor in ready supply in the forseeable future, and I'll probably be worm food before we can plug half the country in at night without crashing the grid.
