I now step down off the soap box and I have no problems with driving a electric car and would love to have one that has the range, power, speed and utility as our two current vehicals, I just don't see the break throughs coming that soon.
Doubt if you ever will, at least nothing us regular folks could afford. And even if you had the battery capacity to do the same speed and range, you'd need one big honking charger and outlet to be able to recharge it in anything less than a day. Even with a couple hundred amp 440V outlet and an industrial charger, a battery pack with enough amp hours to get you 500 miles at 70 mph would take on the order of several hours at least to recharge. You're talking enough stored electricity to probably run your house for a week or better.
Good old fashioned golf cart batteries are still the most affordable, $50 each, 60 pounds each. It takes 20 of them for my pickup to make a 120V 220 amphour pack, 1200 pounds weight. About half that amphour capacity is useable at the currents you're pulling in an EV, so you're only going to be able to pull about 10 to 12 kwhrs out of them. That's equivalent to about 1/3 of a gallon of gas.
My pickup uses roughly 10 kwhrs for the 40 mile round trip to work. To get the same 500 mile range as the CRD, it would need a battery pack able to supply 130 kwhrs. In other words, take that 20 battery 1200 lb pack and multiply by 13. 260 batteries and 15,600 lbs.
Yep, they do have those amazing lithium polymer batteries, but right now you're talking $40 for a 1 amp hour 7 volt battery for an R/C airplane. And unlike the old lead acid golf batteries that will basically charge themselves if you show them a high enough voltage, you need an entirely different charge routine for these new wonder batteries. Basically means you need electronics, charging, and monitoring equipment for EACH INDIVIDUAL CELL.
If these new emissions regs are as asinine as you say, I don't think they're pushing us towards battery electrics - they're trying to push us into fuel cells. And right now, the price for one of those jewels would make even a set of lithium polymer batteries look cheap. Word I'm hearing from those in the EV crowd that's looking into them, talking to the engineers that are doing the actual grunt work research, is that barring some unforseen breakthrough it will be decades, if ever, before these things can be made cheap enough to even start thinking about cranking them out mass production style and putting them in a production vehicle. And that's not even taking into account setting up the infrastructure to support them - maintenance, refueling, etc.
Think about some of the service techs you've run into so far, that were totally clueless about the CRD and diesels in general. Could you imagine one of these idiots trying to troubleshoot a friggin fuel cell?
