It would just need a 1 mega watt charger to charge up during lunch.
A 1.5 megawatt hour battery would only weigh 400 thousand kilograms and cost around a half million dollars lol.
(If 1 Kg of lithium ion batteries can hold 0.265kwh and $1 buys 3.6 watt hours)
Farming machinery is probably going to continue to be liquid fuel powered.
Then some of these machines only get used for a few weeks a year.
Some machines only stop when they put fuel in them and when they get trucked down the road to the next field.
They have to run nearly 24 hours a day or the crops rot in the field.

That's continuous duty?

Doable with a 400 kWh battery at a 1C discharge rate.

Swap packs with a freshly charged one and throw the drained one on a 1C charge, which some DCFC are just about capable of.

Sorry,I don't know.They might run them at 80% like an aircraft or car,but I'd just be telling a story.
We could use a bunch of veterans/experts here at EcoModder.

Very rough estimate based on forums...

The max rate I read was 19 gallons per hour. Many reported around 5 gallons per hour.

19 gallons x 7 lbs per gallong is 133 lbs per hour.

Given a reference to 0.5 lbs of fuel per horsepower hour, that works out to 266 horsepower.

That works out to roughly 200 kW (266 horsepower x 746 watts).

So a 400 kWh battery would give a combine in worst case useage 2hrs of runtime. Swap the pack out with the one that has been charging and you're good to go again.

Heck, you might even be able to get down to 200 kWh or so for about an hour of hard use. That's not too shabby. The only downtime would be the amount of time needed to swap packs.

OK. I'm just using a Tesla 85 kwh pack as a reference here. Assuming we could just tie a bunch of Tesla packs together. Check my math for me though.

An 85 kwh pack weighs 540 kg.
1.5 Mwh = 1500 kwh
1500 kwh /85 kwh =17.65 Tesla packs
17.65 x 540 kg =9531 kg.

Current cost of a Tesla pack is $111/kwh. I know that even if we could get them that would not be our cost. But.
$111 x 1500 = $166,500.

See anything wrong with my numbers?

Numbers look good to me. As I stated, I don't think the goal will be to run 12hr days on a pack, but rather switch them out since such a large pack is expensive.

Oops decibel point in the wrong place. I thought that seemed heavy.
Tesla sure has made their batteries cheap.

Ethanol would be a much better choice to replace diesel in Agriculture.

They could be powered electrically with external power.
It would be difficult to replace the 5,000 gallon diesel battery.
Trains run on a fixed track. The obvious solution is overhead electric as used on most modern passenger trains.
