The other great hurdle that has slowed the uptake of EVs is the price of the battery, but that is falling as energy density rises. Financial analysts at Exane BNP Paribas in September published a bullish report on EVs, saying it expects battery pack prices to nearly halve to $215 per kWh by 2020 from $400 per kWh now. It sees the price dipping to as low as $140 per kWh in 2025.

I was curious, so did a little math for fun.
So lets say you have a 75kwh hour battery car, around what is in a base Tesla, good for about 400km. That battery costs today, $30,000. In 2025 it will cost about $10,500. Let's say that you have a car that gets 8.0l/100km, and gas costs $1/l, so $0.08/km. So $30,000 buys enough gas to drive 375 000km. $10,500 Gets you about 130 000km. Currently, I don't think you will get 375 000km out of a battery pack.
So the cost of the pack won't offset gas costs currently, though may get close by 2020. By 2025 it probably makes sense, but ICE's are getting more efficient as well. 5l/100km will get you about $210 000km at 2025 battery prices.
Anyway, just something I was curious about. If my numbers are wrong, it's becuase I woke up at 4:30 and have only had one coffee so far...and I know all the whadabouts...I was just curious on battery vs fuel. I left out charging costs, and all other externalities.
