Charge Battery On Rollers?

It seems to me there are a lot of people with a strong desire to charge their battery from the grid. What's stopping them from putting together some powered rollers they could drive onto and charge the car through the wheels? Maybe even only one wheel would work. Maybe even a wheel that wouldn't add miles to the odometer. Although they'd probably want it to add the miles to make their mpg average go up.

 

I'm sure you're right, but there are some pretty fanatical people here. If it's 75% cheaper to get energy from the grid and there's a 50% energy loss in the conversion, you could still come out ahead. And the frequency of use would make the small SOC deltas add up. I'd be most scared of trying to get larger SOC deltas each time and killing the battery.

As far as wear on the vehicle, as you said, the OEM battery would fill up quickly. Just consider it an extra hill to go down before you get home.
