Diesel Gen Pod for off grid EV Charging

[goingbush]

Interesting the Tesla Club would come up with this idea , Thought Solar arrays might be more their style,

EV charging with diesel powered ChargePod skid – a solution for locations with inadequate power – Tesla Owners Club Western Australia (https://www.tocwa.org.au/2018/12/11/ev-charging-with-diesel-powered-chargepod-skid-a-solution-for-locations-with-inadequate-power/?fbclid=IwAR0TdShf210eGk1OTubMWmAdlmWuyVFUhPuZpZN_ VOLiWMR6m7njvAe6NRo)

Going to need lots of them given most of Australia is "Off Grid".

The testing methodology is flawed IMO. While they went to great lengths to calculate fuel usage per vehicle, which is valuable data, when working out the entire cost, you have to factor in purchase cost and maintenance. Given the engine would need servicing every 250 to 500 hours depending on how the unit is configured, and these will be in butt **** now where, the costs involved are significant. As you said, why not a large solar array and battery bank? Would have thought the cost would be comparable but even if it was more expensive with lower running costs and much lower and cheaper maintenance it would play out in the end.

It sort of makes sense if the Tesla Owners Club organised a club trip to a destination with insufficient power available. One of them would tow the genset out to the location for everyone to use. For dumping at remote road houses for permanent installation, not so much.

This bloke tows his own gen set .

Is carrying a typical generator and some fuel a realistic option for taking an EV into remote areas?
Just curious...

[goingbush]

Typically 6-8 hours .

My Landy has an onboard 3.3kw charger , If my small 28.8 kwh pack was 80% depleted it would need 23kwh , Anything smaller than a "5KVA" Generator would be pushing hard to provide continuous 3.3 kw , would take 7 hours.

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

Might be profitable to cruise the Iconic 4x4 tracks with one of these in tow.

Isn't towing the genset around the country behind an EV to recharge your batteries at night a bit of an oxymoron?
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?
Cheers Jim

Once you own an EV, there is no need for some mythical purity of intention. Just the questions, "how far can I push this thing?" and "how many peasants can I annoy or impress along the way?". Back in the Good Old Days teams did desert crossings with air or ground supplied fuel drops, "Damned new fangled nonsense, they shoulda stayed home or used camels" said the doubters.

Not with that particular unit - it would last 5 minutes on a trailer. Warranty of 1000 hours or 12 months. Our suppliers give us 12 month unlimited hour warranty - and that’s for hire machines - the most abused you’ll find. We’d expect 20,000 hours plus out of a machine like that, not uncommon for the Kubota powered small gens we have to go well over 30,000 hours without giving any grief. If they only warrant it for 1000 hours, it would be toast by 10,000.

Back away slowly and don’t make eye contact with the salesman... 😉

Tesla Charging Options for Australia (https://www.teslaowners.org.au/charging)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.

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 .

[LRJim]

Yes Jim, you must know that im taking the **** !!I didn't think it would be your style bush [emoji106]

[Blknight.aus]

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

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.

The generators were very economical, way better than a diesel or petrol driving around Australia.
