The Model 3 @linuxluver once owned and was written off due to a meth driver on a one lane bridge has come back to life 😮

I'm really glad it's been repaired. It's an awesome car.

It is! I'm just curious if it will be able to Supercharge, given Tesla's policies around wrecked cars.

Yeah, but a worn down Leaf that's still 9k, add an 8k battery, but you won't end up with a 17k valued Leaf.

We're in that situation ourselves. We've owned our 2012 (Jap import) LEAF since July 2014. Range for the 24kWh battery has now declined to >80km so close to being problematic for our rural commute. The car is probably worth around $10K now, so down $17.5K from what we paid for it which we can justify in its fuel and maintenance savings over that time, especially as it was charged mainly from PV up until shifting property a few years back.

We are considering the battery swap-out option to a 85% SOH 30kWh battery as the $10.5K cost of doing so can be justified in terms of 'paying forward' of future running costs. Also the 160km range that this is likely to result in gets us into the equivalent of a replacement LEAF that would otherwise cost us well more than the battery upgrade, plus replacement signage on a replacement vehicle.

I'd be interested to see how long it would take to charge a tractor to be able to run for 12 hours plus and even what battery capacity is needed for that to be realistic. The ol "make hay while the sun shines" adage definitely applies to farmers, and any downtime eats into potential profits. At least with ICE vehicles they can refill quickly and be back on the job with minimal downtime. Until alternative fuel options can match this I think they will struggle to catch on with farmers

The biggest problem with converting farm and earthwork machines to battery power will be getting them somewhere to charge.

On my uncles farm the bulldozer and sometimes the tractor would be left of in the paddocks and we'd just hop in a 4x4 to get there. The bulldozer could sit out in a back paddock for months on end.

Same issue with earthworks/roadworks. Machinery sits on site and the workers use 4x4 to get there and tow a diesel tank in when needed. You couldn't tow a suitable sized generator for a large number of machines.....and if you could then you have the problem of charging them while they're supposed to be working (but doesn't a large diesel generator then defeat the purpose of a battery digger??)

While there are some electric diggers out there these are generally smaller and designed for town worksite use. Shall be interesting to see how the smart guys get around this.

That doesn't really sound like a problem as such, just 'we do it because it's easy, and we can.' Several possibilities to solve it come to mind - assuming the batteries get to the point where they can last a day, you drive it back in the evening. If not, you can have a truck with a big battery and a supercharger on the back you drive out, charge up in the paddock, and then drive it back instead (or the battery & supercharger get dropped off by a HIAB, and you can swap the batteries over as required till the job's done and you collect them again).

The point is: coming up with use cases that EVs can't currently solve doesn't mean we should just not do anything. Either the solutions will come, the problems will change to adapt to the solutions available, or something in the middle. Sooner or later not changing at all won't an option any more than using a typewriter is an option today. You can if you want, but the world has long since moved on without you.

They may not even be able to use Chargenet...

"A tipster sent Electrek a memo that Tesla sent to employees about updating its ‘Unsupported Vehicle Policy’ and it now includes the following line:

“Supercharging and/or ‘fast charging’ through 3rd party chargers of the Salvage-Titled vehicle is permanently disabled.”

That's not a digger, THIS is a digger, shades of Crocodile Dundee. Real needs need real tools. Id like to see a battery powered tractor doing what our Fiat was used for when I was raised on a farm. Its an easy fix, use diesel. Convert what can use battery, leave the rest. What kept us warm prior to the Industrial revolution? Greenhouse Gases. The Earth relies on GG. Its about ridding ourselves of the excess GG, what we end up putting up there, the Earth will manage it as it always has

Better to deal with low hanging fruit first. That even hasn't started yet. Trying to fix awkward issues like this wont reward much. As time goes by some farm equipment can join in.

How many kW batteriies are needed to drive a large tractor, two large water filled tyres, pulling a plough? Better suited to harrows and drilling, harvesting perhaps.

No, these are cases that do need to be considered now. Once we get to a certain point and EVs take over ICE the cost of fuel will be so expensive that our farming, earthworks and road building become too costly.

There is a reason why these big machines are left out on site....because it is just too much time and effort to get them back to home base. Have you ever driven a bulldozer 5km over farmtracks at night in the middle of winter?

Sure, a truck with a supercharger may work in some instances....but the cost will be huge and your productivity goes down. A simple look at the flyover of Transmission Gully shows the number of machines that would need power. A replacement battery for each of these??......and that won't work on large farms and/or large earthwork sites in the middle of winter either.

As I said, it will be interesting to see what the smart guys come up with.

This was a Tesla-appeoved repair. There will be no issues with charging. It makes a big difference. It's unapproved repairs that can run into trouble.

Now? No. There is no solution now. A small dozer is about 8 to 10 tons, add 50% for an average dozer. Thats a lot of kW to move it let alone push the target

How many electric large farm equipment is there? Id say roughly about zero, yet we have 4 million light vehicles in NZ and we have a small but solid range of EV's. And buses and light trains. Thats where electricity needs to go. If the desire is to electrify every vehicle in NZ that's quite silly. Take a not large tractor pulling harrows, thats doable I assume. How much fuel will that save in a year, SFA.

Start guys will come up with diesel, LPG, Hydrogen, biofuels.

Back to topic, you target a vehicle size thats doable, where there are large numbers and/or high mileage.

Geektastic: Followed yet another truck belching out so much black smoke this morning it looked like it was running on coal.

It’s all very well expecting people to stop buying modern and clean petrol cars but what are you going to do about the trucks?

Never mind the tradies and farmers etc. one farmer around here just spent $800,000 on a new diesel tractor....

Surely this is an oxymoron - clean petrol cars

kingdragonfly: Issues for farmers are torque, maintenance, longevity, equipment sitting unused for extended periods (oil / fuel degradation), and fuel theft.

Obviously an electric equivalent is going to fare better than an ICE vehicle.

The electric equipment available on that John Deere link will fill a lot of niches. For instance that lite tractor with 4.5 hours mowing capacity on PTO. That's all you need for things like vinyard maintenance. I can see NZ's high end producers giving up the stinky diesel soon enough for extra green points.

Kiwifruit and things like that will be more demanding but can't be too far away from that one.

That's a pretty good niche to start with.

I guess he meant cleaner. But remember, EV's are also a cleaner car

EV's aren't clean either. But hey, let's not acknowledge that inconvenient fact.

Nobody claims EVs are spotless. Nothing you do has zero impact on the environment. EVs are simply the least dirty form of transport.
