Abstract

Abstract: Lithium-ion battery energy storage systems are currently the mainstream support for mitigating fluctuations in renewable energy sources such as wind and solar power.Compared with other lithium-ion batteries, lithium iron phosphate(LFP) batteries offer comprehensive advantages in terms of safety, service life, high-temperature performance, and capacity. This paper presents the structure of an industrial and commercial energy storage system using 314 A·h LFP energy-storage cells. For industrial application scenarios, a cooling strategy based on cell temperature is proposed, which improves the efficiency of the energy storage system by 0.6% compared with a cooling strategy based on return-water temperature. Under operating conditions at different ambient temperatures, the energy storage system employing the cell-temperature-based cooling strategy can achieve a high energy conversion efficiency of more than 89% and has good application prospects in the scenarios of peak shaving and valley filling in the distribution network and smooth consumption of new energy.

Key words: lithium iron phosphate(LFP), energy storage battery, commercial and industrial energy storage device, battery cooling, battery thermal management
