Cross fingers hey. I thing the coverage will sort but it will need to be backed by capacity.

Might take a while according to this - Technology adoption life cycle - Wikipedia

However if the 'fuel' companies start making a profit out of EV chargers...

Take the midway service centres on Forrest Hwy between Perth and Bunbury for example. They are only around ten years old and were literally built in a rural paddock beside the highway. They provide their own water and had to construct electricity supply to the site. I very much doubt they constructed any more electricity capacity than they needed then/now. To pivot this development to EV charging is going to cost someone mega $$$ in terms of upgrade of electricity supply to the site. The food establishments are there and distances are perfect for an EV top up on a trip south, but I cannot see how it could be economical for them...?

Easy.
subsidies by using motor club subscription ( nearly all members have ICE cars) or your taxes at work to support virtue seekers with lots of money .

Middy's Electrical in Darwin have a 25kW charger (pay via Everty). As per my earlier post - if someone can make a buck out of it they will appear.

I'm confident that there is a buck to be made to. People are selling electricity for probably 2 - 3 times what it's costing them. The problem is the chargers are expensive and there just aren't enough EV's to make it worth while at this stage.

It's the demand lag I've referenced. When the first ICE cars were sold you bought your fuel in cans from chemists. Petrol stations were some time later.

Fortunately for many they can do most if not all their charging at home. We've owned our city runabout car for 7 years - which is the car the EV is replacing. Now that longer range EV's are becoming the norm everything has changed. In that whole we've owned the city car I doubt we would have needed to charge outside the home more than a handful of times. Like probably every other year.

The nissan Leaf.. as great as it was has given the whole world EV range anxiety. That needs to be pass too.

My thoughts on any charger under 100kW is other than at home or motel, caravan park, shopping centre is they are redundant already. 350kW are about the current tech base line. EV Charging guide: Home and public charging, power levels and plugs explained


Noting my tiny 42kWh battery is just over an hour from empty on a 50kWh 80% is quick. The last bit if much slower with current lithium tech!

The solid state charge will be a game changer for the charge time! QS explains this better than I can

Our little electric engines are getting bigger and more efficient quickly. At least a few of my 80/90s warships had electric propulsion.

Stealth is a key driver then and now I could hear ships over 100km away some times

Yes I pass on that one...
