Abstract:  Prefabricated cabin type lithium iron phosphate battery energy storage power station is widely used in China, and its fire safety is the focus of attention at home and abroad. This paper analyzes and summarizes the characteristics of fire occurrence and development of prefabricated cabin type lithium iron phosphate battery energy storage power station through the combustion characteristics test of lithium iron phosphate battery module under overcharge condition. And based on this, explores and puts forward the basic principles of fire protection design from fire risk, fire prevention distance, fire warning strategy, fire extinguishing system design, water supply and fire lane.

Key words: lithium iron phosphate battery, energy storage power station, prefabricated cabin, fire protection design
