It seems to me that Deutsche ACCUmotive is desperate at this point, they are trying to build business to keep going. LG Chem just announced a partnership with Seimens for grid storage, I don't see how Deutsche can compete with them. http://www.pv-magazine.com/news/details/beitrag/lg-chem-partners-with-siemens-on-battery-storage-systems_100017233/#axzz3JiPRnW5v Electrovaya needs to partner with someone on energy storage, hopefully that is happening with Canadian Solar.
