I'm not convinced that large battery is "bad", although it certainly isn't "perfect".
I would prefer to see range extender. My 90kWH battery, of which I daily use 40kWH, could be 45kWH plus Range extender and the rest of my battery would be available for a second BEV ... which i think would be helpful in early stages of BEV to both spread the limited supply and also solve any range-anxiety of potential buyers.
But that brings the complexity, ICE mechanics, pollution, etc. of having both BEV and ICE, and it seems that Range Extender vehicles have been abused by people buying them for tax rebate reasons and then never actually plugging them in ... particularly (over here at least) for Company Cars where fuel is purchased by Company, so no incentive to use any cheaper source of fuel.
What's the life cycle of my battery? I've done 60,000 miles and lost about 6% of range, and I've had the biggest ("when new") hit, so less range-loss over the next 60,000 miles. I have no idea how long the car will realistically last and be drivable, but the battery has a life as Static Storage beyond that, and recycle beyond that.
Whilst it seems nuts to be carting 1 tonne of battery about, on journeys both short and long, that's the current technology state. Some electricity is Coal of course, but my home electricity is "green" and Superchargers are all Green (in UK at least). So all the electricity that I am wasting hauling that extra weight is as green as currently achievable (yeah, of course extra plant capacity needed to generate the extra that I need, and the cradle-to-grave of that generating plant has a CO2 foot print, but I'm comfortable with it)
More importantly, in this debate, I am driving the change. The solution I am using isn't perfect, but its mega-brilliant compared to my Gas Guzzling, Range Rover driving, mates. So the short term cost of the inefficiency, and increased CO2 even, is inconsequential compared to what the rest of Normal People are doing ... and in driving change that will more quickly create trickle-down for those people, and is also forcing the whole industry to have to abandon their old polluting solutions.
So maybe stop worrying about it and, instead, devote energy to more quickly shifting the rest of the masses to EV? I don't know what is best to achieve that? Take strangers for a test drive ... maybe?
Most of my chums have had a ride already, some have even converted, a number have obtained small PHEV or similar as 2nd car ... "every little helps" ... and plenty are now looking forward to having a BEV, even if Tesla doesn;t float-their-boat. But last weekend I had the chance to take a "fresher" out; I pulled forward no more than 2 feet in a crowded car park and she said "
It really is quiet isn't it" ... would have loved to be a fly on the wall in her car on her way home, to hear what she said to her (Range Rover driving
