Abstract

Abstract: In order to ensure the safe and reliable operation of lithium iron phosphate energy storage power station and reduce the fire risk of lithium iron phosphate energy storage battery, the fire prevention and extinguishing system control strategy of lithium iron phosphate energy storage power plant battery prefabricated cabin is studied in this paper. Firstly, the characteristic gas parameters of early thermal runaway and thermal diffusion of lithium iron phosphate batteries are taken as the detection objects, and the thermal runaway state of batteries is predicted and warned, and the abnormal state of batteries is predicted as early as possible. Secondly, in order to control the potential explosive risk of batteries cabin and guarantee the safety of energy storage system, a multi-level fire alarm control strategy is proposed, by intelligent linkage with the battery management system (BMS).

Key words: energy storage system, lithium iron phosphate battery, fire prevention and extinguishing system, battery control strategy
