A novel fibre sensing technology is proposed to deliver a distributed, real-time and accurate measure of temperature for battery cell. The thermal behaviour of a pouch cell is experimentally investigated over a wide range of ambient temperatures and electrical load currents.
The outlook for the future development and application of optical fiber sensing in battery monitoring is presented. With the proposal of a “smart battery,” real-time sensing by rechargeable batteries has become progressively more important in both fundamental research and practical applications.
Among all the battery sensing methods, optical fibre sensor (OFS) [32, 33] is an emerging technology which can be attached to the surface as well as embedded inside the battery to measure the temperature, strain and other parameters in real-time, to estimate SoC/SoH with the help of algorithms.
Advanced optical fiber sensors can be used not only in batteries but also in other energy storage systems, such as sodium-ion batteries, lithium-air batteries, supercapacitors, fuel cells and other new chemical energy sources. Advanced optical fiber sensors have a “milestone” significance on the road to promoting battery intelligence.
A key aspect for the stable operation of optical fibers in batteries is the correct embedding of the fibers inside the battery, as illustrated in Fig. 2 g. Taking the embedded application of FBG optical fibers in pouch batteries as an example. One initial consideration is the embedding process.
For example, the color of graphite depends on the extent of its lithium content . This has given researchers an idea for monitoring the SOC of batteries by analyzing the absorption spectrum of electrodes using optical fiber.
