2nd Life for Your Battery PAC

[Daniel Scherer]

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?

Gonna be a tad cumbersome toting a 3000lb battery pack to the back yard.:cursing:

The 85 PAC weighs 900lbs and it would stay in the garage where my solar inverter is located.

or build and sell a bunch of these:

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.

I'm going to put mine in a closet and replace my laptop battery each year for the next 7000 years.

Laptop batteries typically use 6 cells (some 9), so technically you'd only have 1100 years or so.

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.
