Rent Changeable Batteries (Tesla batteries to be changeable - like a toy car :) *Suggestion*

This should be the easiest solution to range & charging problem.
* Suggestion *

You own the Car not the Batteries.

The batteries are owned by the "Gas Company"
You just go to a "Gas Station" that now will be called "Battery station"

Filling up a car with gas takes a couple of minutes.
Have a car batteries removed and inserted would take less time.

A standard battery is first needed.
The cars will not run on 1 big battery but of many smaller ones liked together.
Every battery have its own identification and onboard controller that can fast report its location among the other batteries and its capacity and condition.

Now, how would it work to change batteries?
Well you, the car owner does NOT change the battery manually of course.
Every car has its batteries dock in the same location underneath the car.

Align the car at the station
At the "Battery station" there are small "holes" at the "pump" where the cars wheels fit.
You drive so the cars wheels are in those "holes".
Now the car is aligned.

The "Battery station" connects a mechanical battery offload/onload arm underneath the car.
The station reads the status of the cars batteries and present the data to the car owner.
You then select capacity (how many) and the mechanical arm removes and replaces batteries.

If the batteries to be replaced have remaining electricity.
The cost is deducted.

Because you don't own the batteries it doesn't matter how old they are.
The rent cost of the batteries covers the "Battery station"-company cost.
Every battery is tracked by the company so when its recharging capacity is to low it is take out of service and recycled.

This is the umpteenth time a version of this has been suggested. A company called Better Place has been trying to operate the concept for years, trying it out in tiny markets (Denmark and Israel) first. It is flipping CEOs and trying desperately to avoid bankruptcy -- because the capital costs and inventory necessary are ruinous, among other reasons.

Tesla's batteries are already swappable. But no viable business case for doing it routinely can so far be made.

Thanks for the reply

Still I think this is the way to go.
Didn't say it going to be easy.

They are working to install public charging stations.
Why not battery swapping stations?

Current fixed batteries requires 1h+ to recharge.
Perhaps when they are down to a couple of minutes.
They are researching to use capacitors instead of batteries in mobile phones so that is perhaps a better way.

There is a battle of two standards, as Brian H mentioned. The battery swapping idea would require a much higher initial capital investment, which would have to include an inventory of batteries. The Supercharges require no tecnicians and is available 24x7 while the battery swapping model requires specially traines staff at every location and service is not likely to be available. When I drive from Virginia to New York City, I generally stop in Delaware as it is about half way. By the time I get my Model X there should be Supercharging locations in Maryland and NJ too. Also, if you are on a long trip and your battery is swapped with one that does not hold a charge very well, you will be out of luck by the time you realize it.

Batteries "like" current and can accept it at very high rates if deeply discharged. Problem is again infrastructure, you just don't see 440+ V available everywhere.

Conceivably just as strong a case could be made for chains of Very High voltage / amperage charging stations "much like gas stations of today" where you could dump insane amounts of current into a depleted battery up to approx. 80% SOC in 15 to 20 min. It might prove faster and less costly than hoisting the veh. removing and replacing the entire pack, you'd have to pay labor for someone to do that when all you need is literally a few $$ worth of electricity.

If the industry can get a handle on charge times through infrastructure investment swapping batteries could seem archaic rather quickly. Similar to pulling into a filling station and removing the empty fuel tank from your ICE and replacing it with a full one as opposed to quickly refilling it and being on your way.

@Grimmy: Here is a great article discussing what Brian H was talking about:

Thanks to everyone that replied.
Good info from all

Future looks promising :)
