Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
That is what you want to do, but that is not the smart grid way. The system depends on not only you charging your car at night, but you also having your car's battery available in the evening to support the extra demand caused by me watching my TV. So you will be plugging in your car when you get home and leaving it plugged in until morning, because your rate will depend on the times that you have it plugged in and the amount of charge or discharge during that time. If you try to sneak out at 2:00 am and plug it in for charging, you will pay a higher rate than if you leave it plugged in from 6:00 pm to 10:00 pm to provide support for my evening TV viewing.

what i don't get about this system is how it will affect length of battery life. surely the more charge cyles a battery endures, the less viable it becomes, n'est-ce pas?

so if you leave your battery disconnected after charging, it lasts longer, but you're leaching without seeding.

unless you're paid for the seeding part, or the batteries are owned by the utility...

how to work around that inconvenient truth?

The way it works in hybrid cars is that they avoid full charge and full discharge. Apparently the "wear" or damage to the cells occurs at the full and empty points, so they only use about the middle 1/3 of the charge-discharge range. Experience suggests that batteries last a long time using that model.

talks a bit about V2G (vehicle to grid) charge-discharge scenarios....
