Hey, if I buy an electric car I don't want to wake up in the morning to see the battery is at 10% because of the lack of electricity they had to compensate. What about that? And than everyone will have to get it charged from the net since they don't have the range to get to work, how would you compensate that? Or in the other case people with such statements could be smart and say 'hey, let's make a deal that you in the morning will at least have 80% left in the car' I would say that would be great, but than the problem is since only 20% of the battery can be used, only 20% of the projected storing capacity will be free to cut down high and lows. Than maybe a giant monolithic battery would still be needed... Oh and on the other hand, good luck with trying to use hydrogen cars for this plan. I'm sorry so be so skeptic, but I believe there are better ways. Such as storing an overload of energy in biogas or hydrogen to burn it in a generator when needed... Or to propel a car...,(reply>), +Chris Hughes (crh23) Than why would they claim that there wouldn't be a need for 'giant monolithic batteries' or other kind of storage facility just bin using the electric cars' battery... As I said, if it wouldn't affect the independence of the car I wouldn't be bothered, but for what I see know most are vague about it, never claiming his much impact it can have on the car, even worse, they count the full battery storage potential of the electric cars and than speak about that total being the total potential that could be used before having the need of 'a giant monolithic battery' which for me means they full use the full potential of the car, that could give the risk of having not enough electricity in the car to get to work. And yes, fast chargers could help in that case, but if I plug an electric device in the wall, I want it to be charged to at least a useful load (as iPhone user I know how hard it can be to have not enough battery power left)... Just my opinion though,(reply>), Keep in mind that the point of this isn't a long term power shortage: this is for immediate pick up, so it would only be a few minutes of discharge, which isn't going to cause a significant problem for running out in the day.,(reply>), +rationalmartian within a few hours doesn't sound quite fast to me. If I had to leave for work I wouldn't wake up hours before to get it fully charged. That's one of the reasons why I prefer fuel cell cars above electric cars, fast charged. I would like for people to believe in this 'electric car as a buffer' system to show me the numbers of reality. Because in theory everything can sound great until reality hits in... That is what I fear that could become the problem here, or there would be a complex system to make sure ones vehicle would be charged when needed, or just left at let say a minimum of 80% charged for unpredicted use of the car. Or there should be another magical way to assure people that the car can be used at al times when needed. It is pretty paradoxical to try to use an battery-electric car as a temporary electricity storage and as a car that should compete with the independence, range and full time availability of a fossil fueled car...,(reply>), Pretty sure it wouldn't work like that. At any one time given such a large infrastructure envisaged, there would always be enough vehicles that were near full capacity or full charged that some could be used for short time spans for load balancing. The computers on the system would be aware of the times the car was usually used and so could make sure it was charged ready for that time. Also let's not forget this would no doubt also be a high current fast charging infrastructure, so a vehicle could recieve a full or 80% charge within a few hours if needed.
