The peak voltage of 120v AC is 170v, which should be plenty for most DIY EVs.

Directly rectify the AC, maybe with a voltage doubler for higher voltage batteries, and then use a buck regulator. Should be easily achievable using mostly off-the-shelf components. Start in current limit mode and switch to constant voltage once desired voltage is reached, then completely turn off after a while (or go into float charge).
If America manages to eliminate obesity, we would save as much fuel as if every American were to stop driving for three days every year. To be slender like Tiffany Yep is to be a real hypermiler...

Allie Moore and I have a combined carbon footprint much smaller than that of one average American...
