replaceable battery

design the next electric car with a removable universal batt pack. pack can be good for 50-75 mile range would be sufficient, since most ppl drives 30-50 total miles to work each day anyway. packs can be charge at home or quick exchange station. pull up to change station switch your old for the fully charge. just like fueling w/ 10 gallons and go.

I think this idea right! Since it is possible to create a network of workshops, where it will be possible to replace the battery with a charged, where it will serve to determine the remaining resource. It is only necessary to standardize the vehicle's battery and structural facilitate installation.
