Their use in grid frequency stabilization applications is especially interesting as this is one of the situations in which battery storage is first reaching installed costs low enough to represent significant competition to gas peaker generation.

I hope Germany has a lot of Mexicans moving there. If so, they should have plenty jumper cables to get the lights back on…..
This is a pretty good idea. Those batteries are still very usable and in that application may last a LOT longer than they did in automotive applications. Mercedes is planning for similar uses.
Pretty clever seeming. Reminds me of reusing spent nuclear fuel.
I wonder if batteries eventually stabilize to a lower capacity, like say 50% of original, and then kind of stay there, or do they taper down to zero. IOW is there a plateau or a slope.
...their low cost is an advantage over using brand new devices...
Audi prolly pay folks to take the batteries rather than pay a green fee at the landfill
4.5MWH is a lot of batteries.
But the concept is hardly new. The home-made Electric Bike and ‘power-wall’ builders have been reconfiguring and repurposing E-car battery packs for years.
Which means that German Audi owners are spendthrifts who’ll buy a new battery and discard the old one while it still has substantial (80%) remaining usable capacity.
