Abstract |
This paper proposes a diagnosis algorithm using internal resistance for a large-capacity (MWh or more) lithium-ion batteries energy storage system centered on field application. Therefore this paper identified the current status of Li-BESS construction in South Korea and analyzed the internal resistance characteristics and measurement technology. In addition the proposed diagnosis algorithm was demonstrated to reflect the specificity of the field. Future research requires more specific correlation analysis between internal resistance and BMS information. |
