[ausev] Electric energy transfer and storage limitations

[jefoy at mindspring.com]

By selling this as a concept that includes the oil companies you don't preclude the opportunity to use solar or wind generated power, you just leverage them into a position of embracing the concept as an opportunity to expand their product offering. With that much capitol available, you want them to lobby for the idea, not against it! You also want to leverage their existing distribution network, otherwise you still have the problem of early adopters being frustrated by the lack of conveniently available exchange stations.

>Imagine the concept of purchasing an EV without a battery. For power,
>you sign a lease agreement with a battery supplier (Exxon, BP, etc.)
>with the stipulation that you will not abuse their battery and in
>exchange they agree to supply you with a charged battery at any of their
>affiliate "filling stations". You pay an initial security deposit and
>the cost of the electricity used to charge the battery.

>The concept is the same as the "Blue Rhino" propane tanks, you can have

>charge than just filling your own).

>The company that owns the battery has the incentive to invest in state

>of their batteries. They can track the battery history through on-board
>data logging to record excessive depth of discharge, number of charge
>cycles, average lifetime, etc. The car owner has the option of charging
>at home or the filling station exchange. The car owner never faces the
>worry of having to replace a bad battery pack unless they have to pay
>for "damages" caused by abusing the leased battery (prorated by the age
>of the battery). There might even be "damage insurance" that covers the
>battery.

>The companies that own the batteries have an incentive to invest in
>improved battery technology. "get more miles per charge with the Exxon
>Maxicharge" or "feeling a little sluggish, try the new premium battery
>from BP, more peak amps than any competitor".

>The infrastructure is already in place, many older combination stations
>already need something else to use the repair bay for. For just a little
>longer than it takes to fill a big car (and what better enticement to
>get you into the convenience store for a soda and a snack), you get a
>fresh battery and are on your way.
