Better Place Electric Car Concept Wins INDEX Award

My other issue with the battery switching is that battery technology is finally growing leaps and bounds with the acceptance of Hybrids... if you use battery switching you settle on a type and size of battery now. Effectively halting battery developement. That is the biggest reason that internal combustion engines have thrived so long you can have many different combinations of power level, engine type and fuel storage level vehicles all serviced by the same fuel pump.

Nice that someone is putting there own neck out to try to make this viable. My biggest issue with battery switching as opposed to developing a quick charge battery is what happens when I pull in pay my 50 dollars at a change station so I can drive out of town in my brand new car and trade my brand new battrery for a 10 year old one and it dies a week later on my local runs around town where I am not switching I am charging at home who is responsible to cover the cost of that $5,000 battery? ...

Thats exactly why I don't like the concept. There are battery designs out there in testing that can be charged to 80% in a couple of minutes. Charging to full can be done at home as it takes much longer but 80% is fine for extended motoring. There's also an experimental Li-ion battery using nano silicon instead of graphite that could increase energy density up to 10 fold. There's also a capacitor maker that claiming Li-ion energy density with lead acid pricing and also instant charging.
