Not noob at all
I am under the impression that there will be an outlet that plugs into a special charging point, and a household point that will also be available. Some vehicles require you to have a special point installed in your house, I might be wrong.
Some of the electric offerings give you a poor range, so some people (and this was highlighted on Top Gear) could take up to 3 days to get to work, and then three days back. The actual charging time can be anywhere from a quick charge (8 hours V. limited range) to a full charge, anywhere from 18-36 hours.
Standardising the batteries would be a great idea, and one that would put Toyota to shame, there electric battery actually does more harm than good, when you think of the production AND disposal processes involved Toyota's battery is very harmful to the environment.
Your pre-charged battery idea is a genius one, and probably one you should capitalise on, but from what I gather, most EV and even hybrids, don't have removable batteries as such. Apparently Renault will be producing an electric car soon and part of the deal is that you RENT the battery from them, that is a removable unit, so you can take the battery in at night, charge it in your home and pop it back in in the morning.
I have made a similar point, we;ll be burning more fossil fuels etc, to charge the cars up as this country (the UK) doesn't have enough green energy available to us. PLUS 99% will have to fork out an extra £300+ to subsidise the power companies efforts in this area, which I find highly amusing when you think about the millions/billions they make off us all in profit every year.
I think, with the Nissan Leaf as an example, it was figured that, because it was such a lengthy charging process it would cost approximately £8 in today's money, to fully charge the car.
When you take the production/disposal processes, charging the vehicle using fossil fuel based electricity and so on, these cars are no greener than a small engined petrol vehicle. At least the petrol vehicle will get me 400miles before I have to fill up...
