This work describes an improved risk assessment approach for analyzing safety designs in the battery energy storage system incorporated in large-scale solar to improve accident prevention and mitigation, via incorporating probabilistic event tree and systems theoretic analysis. The causal factors and mitigation measures are presented.
To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
Battery Energy Storage System accidents often incur severe losses in the form of human health and safety, damage to the property and energy production losses.
Despite widely known hazards and safety design of grid-scale battery energy storage systems, there is a lack of established risk management schemes and models as compared to the chemical, aviation, nuclear and the petroleum industry.
During the charging and discharging process, heat in the battery originates from Joule heat, chemical reactions, and phase transitions. Specifically, higher charging and discharging rates result in a rapid increase in battery temperature, thereby accelerating battery aging.
