larger battery packs with the current technology may not be the best option. i think the charging network is the way to go. if we could charge EVERY where we parked, we would hardly need more than L 1 charging.
we leave home with a 100 mile range. drive 15 miles. stop plug in, recoup 5 miles. drive another 15 miles plug in. recoup another 5 miles. drive 10 and plug in, recouping only 5 miles at a time. we could make 5 stops, go home and have "half a tank" left.
sure some will need faster charging, larger packs, but most of us wont and i am betting the "wont" crowd is over 90%.
the validity of building the infrastructure hinges on one question; is electric vehicles a flash in the pan? will hydrogen make them obsolete or undesirable? .
imm, even if hydrogen came out tomorrow, electrics will still have a market.
so why not build the charging infrastructure? we will be using it until the flux capacitor is perfected and that wont be for another 47 years
