A third party commercial validation of Energy management systems developer ZBB Energy Corporation Agile Flow Battery has been successful.
The validation measured performance parameters, including maximum capacity, rated capacity, on-line self-discharge, safety, efficiency, and state of charge accuracy.
Examiners at the testing facility in Beijing, China, concluded the battery had a rated energy capacity of 55.7kWh, rated charge of 16.5kW and rated discharge of 12.5kW.
The battery also delivered 46.9kWh of energy after 12 hours of operating in idle mode, the tests found.
Maximum state of charge inaccuracy over the 0-100-0% charge/discharge cycle was 3.15% and 0.73% on average. Cycle to cycle energy discharge variability was ~0.5kWh, max-min.
The battery was specifically designed for behind the meter energy storage applications in the commercial and industrial building market
The commercial validation was the culmination of a product development program started in July 2014 and utilized concurrent engineering, procurement, assembly and testing between ZBB Energy and Meineng Energy.
