Eugene, while large batteries for electric vehicles can be expensive, it's not merely gas and maintenance where the savings are. Recharging your EV at night and reselling surplus power to the grid during the day (V2G) could result in a credit of $3 daily or $1,095 a year, or even more if you could additionally recharge your car from a solar parking lot during the day. U.S. power grid chief Jon Wellinghoff said EVs could earn $1,500 a year in paybacks for their owners when their batteries are connected to the power grid. That amount of money buys quite a bit of battery power, the battery will pay for itself over the years. Moreover, ongoing innovation and mass manufacturing and the associated economies of scale will drive down the price of batteries.
