EV cars idea

I can't remember who it was that said it but "a captain thinks of weapons a commander thinks of logistics"

I guess it sort of means even if you have the meanest weaponry if it's not where you want it when it's needed you might as well not have it, which may well be why the Romans were so successful because of all of their roads.

So the secret to success is logistics, and that's where I came up with this idea

Making EV cars with bigger and bigger range may not be the answer.
Make EV cars that take exchangeable batteries, each battery could give a limited range as long as there’s another charged battery ready for them to pickup.

The batteries themselves could be recharged at any number of charge spots by any means of creating electricity, this could be sunlight, wind or fossil fuel.  Once charged these batteries could be shipped to outlets such as current petrol stations ready for someone to exchange.

The change of a battery should be simple so that it doesn’t take a long time.

People on the scheme could pay-as-you-go so would be charged at a higher rate for the energy used and some people could be on a pay-monthly subscription where they have an allowed usage and anything over is charged at a higher rate, exactly the same as mobile phone usage.

Batteries could be constantly monitored with regards, charge, capacity and even location.  Through this monitoring it should be possible to ensure there’s always a battery charged and ready within range of a car running low.

People could join a subscription whereby a new battery is delivered to them when the current battery runs low just like the milkman used to deliver milk, often using an electric vehicle.

By doing this you could even have different vehicles being able to carry more batteries and even allow a smaller half charge emergency battery to be carried that would give enough power to get to the next battery depot.  This could be a rechargeable battery and the main batteries are only chargeable by the charge stations.

The monitoring could be used to check for tampering and actual usage statistics could be used for billing just as meters are used on households at the moment.
