Aquion Energy signed a memorandum of understanding (MOU) with Siemens Industry under which both parties will test the integration of Aquion’s AHI batteries and Siemens’ Sinamics S120 drive technology. As part of the MOU, Siemens purchased an initial set of Aquion batteries for immediate shipment to their manufacturing and test facility in Alpharetta, Ga. Siemens’ Sinamics S120 inverter solution and Aquion’s AE12 Battery Module product are currently under high voltage test at Aquion’s R&D facility in Pittsburgh, and will undergo additional joint testing at Siemens’ Alpharetta facility.
