Eh? How is it the basis of my augment, try reading everything as a whole rather taking things out of context.
When you said 15k is the cost of replacing your car, then it absolutely was the basis of your argument. You're not supposed to look at the cost of the whole car, you're supposed to look at the cost of adding hybrid/PHEV tech, i.e. the differential. You did later, and that's why you went from 15k to 6k, but not originally.
No it isn't, that's 6K on a car with substantially higher fuel economy than I currently drive, get's you to a pretty similar period of time to recover the cost as it's burning 50% less fuel than I am currently.
50% less fuel? So you're talking about 70MPG cars now? What car is this? How many people are buying them?
Look at a performance sedan like the M35. The hybrid gives you the same performance as the non hybrid (~10km/L) for €6k. Add 10kWh of batteries (maybe €4k), and every charge/discharge (40km) saves you 4L (€7) of gas but costs under €0.50 to fill at night. Interest rates are low, so it'll take under 1500 cycles to break even.
There is definitely a place for PHEV even when you ignore the environmental benefits, and in a few years it will be economical for the majority of european car buyers.
Electricity costs are more likely to be around 25% of the fuel costs
If you charge during the daytime peak, that's possible. Market electricity price at night is near zero (
example), so assuming night time electricity users aren't subsidizing daytime users (which is unfortunately the case in areas without smart meters), it will be much less than that.
Your also ignoring the fact that many fleet cars are high mileage i.e. they don't do short enough runs for the overnight charge to get them through the following day, so fuel costs will still be far from zero
In that case, the battery gets used to its fullest ability and maximizes gas savings. Maybe gas costs without PHEV are 200/mo and with PHEV are 60/mo. The savings are still there.
Look, this is what the numbers boils down to: How many miles can each kWh of a battery displace, and at what cost? If you can do 2000 cycles (A123 is saying 80% capacity after 7000 cycles, so I'm being
very conservative), it will give you ~10000 km for a ~$700 battery and $100-$200 of night electricity. For you, gas is $2.50/L, so a
typical 7L/100km car will need $1750 of gas to cover the same distance. So that's ~$850k saved per kWh of battery. All you need is enough batteries (and matching daily driving, of course) for that to cover the electronics, electric motor, R&D, etc.
Interesting suggestion, but the manufacture looses on low mileage users and high mileage users loose as well, so it isn't profitable to everyone.
True, but that's why you sell to corporations first. They have an idea of what mileage will be put on, and you can use different sized batteries.
They don't, in any country, if you do the math in an unbiased fashion. See above.
They do. See above.
