Re: Whisper it…

@Defiler - Electric cars have a long and checkered history dating back to the 1890's/1900's Brass Era cars. They have failed several times in the market for basically the same reasons of inadequate range and lengthy recharging times. The range problem is partially fixable, bigger battery but at the cost of greater weight. So there is a trade off between range and overall vehicle weight. The recharging time is limited by the battery chemistry and cannot be safely pushed or you will have some very serious problems; problems that vary according to the battery used. Also, a problem for EVs is there only certain battery chemistries that are suitable for an EV (voltage/current discharge curves versus power demands).

Other issues include the lifetime of the battery pack and its replacement cost. Currently batteries need to be replaced fairly often (I have seen reports about every 60K miles/100K km). This is an expensive proposition as the battery packs are not cheap. Again a problem that has been around since the Brass Era.

So the question isn't the current frenzy but whether it will last unlike past efforts. The really becomes a question of whether most people will find an EV an adequate first or second car. If not, the frenzy will die as sales collapse.
