This is going to make electric cars extremely cheap once the million mile battery is out. Probably at least 50% cheaper given the money you can make selling off peak electricity at peak prices. Electricity costs by me since I switched to time of use are 4x as much on peak vs off. My Tesla costs about $6 for a full charge off peak. It seems like its easy to make (4-1)* 6 = $18 a day off of this the car as it home. Let's say $10 after conversion loss and battery wear, etc. Once you buy any other hardware needed (I think they are $2k-4k now), this seems like free money. Worst case, car is home during peak 2 days a week and $10/day gain, $4k system: 2.5 year payback period and then $223/month income Best case, car is home during peak 5 days a week and $15/day gain $2k system: 26 week payback period and then $322/month income. The best case over 10 years is worth $38,700. However the biggest opportunity here is probably for Tesla to lease the battery to consumers. The car will be discounted significantly if you can plug in 3 days a week near peak usage.
