Things to think about if EVs become the vehicle of choice.
1. Who is going to pay for all the charges required when you are on a trip and need to pull into a charge station?
What costs are you referring to. If you mean the cost to charge the car, then the user pays just like you do for petrol/diesel. In fact it is becoming much easier now with the main charge station companies allowing you to register the VIN of your vehicle and then the billing automatically is processed as soon as you plug your car in. So no messing around with cards and apps and so on. Optional of course.
2. It costs between $5,000 to $7,000 to replace the battery pack on an EV. Incorrect charging can destroy a battery pack very quickly.
All EV's have very smart chargers and battery management systems built into them. You cant "incorrectly" charge OR discharge the car. There are some unconfirmed reports that constantly using fast chargers will reduce battery life, but its all too early to tell exactly what the effects might be.
3. Who would every trust the salesman if purchasing a second hand EV that the battery pack is good to go.
As if a salesman would know. Ask any of them any sort of technical question about any vehicle and you'll normally be met with a blank stare, or some Bull.... gabble. It's really the same as asking if the engine is any good on an ICE vehicle, except you actually have more information in an EV because they all include a display that represent the battery life eg: the Nissan Leaf have a "% of new", the Teslas have an "expected range".
4. Saying technology will resolve the distance travel issues is no assurance it will ever be overcome.
That's a bit like saying that future ICE vehicles will have a million mile capability ala the Mazda rotary engine with no parts to wear.
In any case its a bit of "horses for courses" argument. If you buy a Mazda 2, can it travel around Australia?. Well of course it can, its just uncomfortable and slow. Can you drive a Nissan Leaf around Australia?. Of course you can, its just uncomfortable and slow.
5. I can see a time when the highways and byways will be littered with abandoned EVs with flat or worn out batteries and pollution issues with redundant batteries like today's tyre disposal problems.
I dont see why that will be the case, anymore than you have the highways littered with worn out ICE vehicle. In fact with the low mechanical parts count of EV's there will be less litter. No waste oil, no worn out brakeshoes/drums/discs, no wornout clutches, no wornout belts/hoses/radiators/alternators. etc etc.
Its probably a bit early as yet to be certain, but the expectation is that batteries will far outlast the current average ICE engine. When they do fail, they can be used for stationary storage and with the current technology of battery can be almost completely recycled to create new batteries. After all a Lithium battery is 80% Nickel, 5% Lithium and the rest is various metals and structural components.
There doesnt appear to be much recycling happening ATM, but used vehicle batteries are currently snapped up by EV and home power enthusiasts.
