The fact is that the 'home fuel generator' would then cause the closure of many fueling facilities which would then cause further inconvenience for motorists and a hike in prices.

Even Sales reps and delivery guys can run up to 2 tanks of 'energy' a day. Sitting around waiting 6 hours before heading out again isnt going to do anyone any favours.
Factor in battery degredation and those guys will be pulling batteries out every 1-2 years.

We're now eyeing off the Rivian as an option - it has enough range to make a trip to Adelaide viable, will then need several hours on a charger to return home though - so currently the ICE vehicle would do the run unless we planned an overnighter. Imagine the charges a hotel or park is going to slug to charge such units in the future - will make the accommodation twice the price!

The big kicker will be how the government will recoupe lost fuel excise. No-one has spoken of this in parliament to this date. And they wont be giving up a revenue stream any time soon.

Batteries have a life of 10 years plus, cost of filling up 2 10KWh batteries I have at work for a UPS is at above 8% efficiency (or free from solar pv ) about 30 cents per kwh or roughly $6 for me if (and it never happens ) I took all the power to charge from the grid to empty batteries. Hotels charging my car or electric motor bike ( I have neither yet) would be hard pressed to try doubling prices for allowing me to have a few $ of electricity.

The fuel excise is a minor tax adjustment issue. Those sods get most of my money no matter what we do


EV Charging From Grid Cheaper And Greener Than From A Home Battery

Have you had a look at Batteries – Lithium Ion Battery Test Centre

Fuel excise will be a MAJOR tax adjustment issue

Using the data provided by Tesla - their cells lose approximately ~2% capacity per year of normal use. most are down ~10% by 3 years. Thats significant for an average use vehicle.

And never underestimate the power of the almighty dollar - in the USA they're now charging for you to air up tyres! $1.50 a pop.

Once Australia has no longer got access to Coal etc and we are renewables and battery based the rebates on those will go also, then watch power prices lurch forward again.
At the same time, fuel consumption will begin a sharp decline, and prices will rise to maintain profit margins.

Its going to be an interesting ride.

It’s easy to sort,just start with increasing the rego for EV’s.

Now that would go down well with some,but ATM,they are getting a free ride,everyone else is paying for them.

The only real fair way,as fuel excise is a user pays tax,is to monitor mileage,so it’s definitely a difficult one.

They are going to have to charge for it,it isn’t going to be free or some discounted rate.

I presume you now pay for fuel at the bowser,no difference.

For a start there are HUGE infrastructure costs.

Ev’s Need a huge amount of power to recharge.

And don’t think a motel will use solar,there is no way it will provide anything like enough power to charge a couple of EV’s,yet alone many.

The Infrastructure is already there, plug into any powerpoint.

The 5Kw solar on my house has more than enough electricity to charge mine, & I only need to charge once every two or 3 days. (16 Amp circuit) Done 9650km now since I got it on the road , every km powered by the sun. still have credits on the electricity bill except when the Pool heat pump is running. (32 Amp circuit). Never used a public charge point except to see if it would actually work. (Tesla destination charger at a local winery)

It’s not there though - most Caravan parks etc are limited to a total current draw and a heap of EVs will quickly exceed supply. So upgrades will be needed.

Your application is a bit unique. It’s not a daily, it’s not used continually. And your journeys are planned to fit within its capability else you use another vehicle.

As an example - if you can jump in it, drive to Melrose and home again stopping for simple 10 minute stops - I’ll be all ears.

Note: I’d happily have an old series with EV as an around Whyalla runabout, it would never go anywhere else though as even a run to the nearby lighthouse would see it stranded.

I have seen some creative excuses for visiting a winery, but that one would have to be the most imaginative one yet.

"I only went to the winery to see if their charging point worked."

That ranks up there with the elderly couple who claimed they only drank as much wine as they did because they were collecting the corks for craft activities at their grandchild's preschool. (Of course that excuse no longer works with screw top wine bottles. )

There is an argument that rego should be cheap and fuel (or energy) should be dear so that there is an incentive to use the private car less or to use a more efficient one.

If rego is dear and fuel is cheap, you don't save much by using public transport instead f your car.
