Abstract

Lithium-ion batteries are extensively utilized for their advantages such as high energy density, environmental protection and long cycle life. there are pressing issues that need immediate resolution such as safety, stability and reliability of lithium-ion batteries. In view of this, this paper studies a fiber Bragg grating (FBG) sensor implanted in 280 lithium-ion battery to measure cell strain technology, through the reference grating based method to overcome FBG temperature and strain cross-sensitivity problem, this method can be used to analyze the operating characteristics of lithium-ion battery.
