How many others have considered plans to keep and use your battery PAC after it reaches the end of its useful car life. I have a solar panel system and would like to use the old PAC for storing power for night use. I know Tesla has a current system for this now but will they have a system available based on these car pac's? I've also considered they may have a core charge of some type if you don't turn them back in. Thoughts?
I fully plan on mounting my old pack and use it as part of a grid tie system. At the very least I would charge it at night with crazy low ToU rates, and discharge during daytime peak rates. I was actually talking to someone at work about what would happen if I needed a new battery. And they were asking if I would try to use my battery in this manner. Hopefully that is 10+ years down the road though.
Four, five years in and Roadster owners are still a long way from even considering such a thing. With a doubling of energy every 10 years and a drop in prices maybe buying new cells will make more sense?
You'd buy a new battery for the car, but then you have the old one which hopefully can be reused at a reasonable level of cost and difficulty.
