Say a 100kwh Tesla with onboard 11kw 3 phase charger , was 80% depleted , needs 80kwh for full charge , would need a 15KVA generator & would also take ~7 hours .




here is the Tesla Charging Options, could work for any EV of a similar capacity, IE Bollinger / Rivian

Awesome. Electric motoring all day, listen to a generator all night.... NOT.

Would prefer some sort of on board genetator setup that you run for say a couple of hours when motoring along to top for a few hours of electric only running.

Wouldn't you be able to rig up some sort of greener generator for the same weight and size? Solar panels and battery bank or some wheel alternators or regen braking or some other crazy EV technology?
And how much diesel would you need to carry? 5l per night? 20l per night?

Absolutely, I hate generators with a passion. A silent capstone type turbine generator would be acceptable.

The whole generator thing will be moot pretty soon, I read something the other day about non rechargable diamond batteries using nuclear waste that lasted 2,500 years , Now they would do a few circumnavigations of the country .

I didn't think it would be your style bush [emoji106]

really roughly....

1l of diesel equals about 3KVA for an hour. Thats based loosely off of what I was getting out of the 7kva genny on the work truck which was a big thumping single cylinder with a 22L tank. Its also about right(from old memory) for the 2.4kva single pot diesel I used to have for running compressors and small welders it had a 2.5l tank and averaged 6-7 hours between fills with the compressor running about 50% of the time or driving the welder/urn/coffee machine.

My piddly 2.4kva inverter petrol genny worked hard drinks its 5l in about 2 hours

Haha, so all of the self declared greeny "Nuclear Free" shires would have to rescind their declarations in order to permit green vehicles to enter them? [emoji854]

I hate generators too, but I work with the bloody things all day. People think I’d be just the right person to talk to about what to buy as a camping genset - my first response is I do everything with solar and batteries in my van include watch TV if that’s your thing, run a fan all night off the inverter, run a 90 litre fridge, charge devices. I’ve never run out. Short of running an AC in the van (which I get depending on where you’re at) I don’t see a use for one.

That tesla page where they organised generators around Australia had some good usage figures. The generators were very economical, way better than a diesel or petrol driving around Australia.
Cheers Jim

Drop off a couple of Tesla Powerpacks and 50KW of ground mounted solar round the back of the roadhouse, let them run the business off the Powerpacks and keep the diesel genset for backup. Easily upgraded for bigger usage.
