The StoraXe system is produced by German technology company ADS-TEC. ADS-TEC integrate their own BMS with Kokam lithium-ion battery cells manufactured in South Korea. The cells are 3.7V (nominal) 75Ah pouch type (Li-polymer) with an NMC cathode.
Kokam was established in 1989 and entered the battery business in 1998 after developing the polymer cell. The cell is now produced at large scales and marketed as having long life cycle life (60% SOH after 8000 cycles @ 80% DOD) and high energy/power density (~170 Wh/kg and 2C/4C continuous charge/discharge rates).
The unit is connected to an SMA Sunny Island inverter that will charge/discharge the batteries.

Testing update: Unfortunately on the 26th of October 2016 the KOKAM Storaxe Battery under testing in this trial experienced a BMS fault that caused it to discharge to a level that has irreversibly damaged the battery cells. This has rendered the KOKAM battery unsuitable for further operation or testing under this trial. As such, there is no live data available for this battery module.
