Are optical fibers safe in a battery management system?

Block diagram of the battery management system with FBG internal sensors and low-cost photodetectors [ 165 ]. A few concerns have also arisen about the insertion safety of optical fibers into batteries and the durability of the materials both on the fiber side and the battery electrode side.

What are the most expensive components in a fiber optic sensing system?

Addressing this concern will require a critical assessment of the value of reduced incidents and predictive maintenance enabled by better data collection during operation [ 164 ]. The most expensive components are the light source and interrogator/spectrometer in a fiber optic sensing system.

Can optical fibre sensors be embedded in battery modules and packs?

Thus, the implementation of optical fibre sensors being attached on or embedded in battery modules and packs still needs to be carefully designed depending on the mechanical and optical characteristics.

Are optical fibre sensing methods attracting more interest?

The results straightforward show that optical fibre sensing methods (marked with red shadow) are predominantly attracting increased interest compared to other sensing methods. Table 1lists some of the main sensing methods being developed for monitoring different parameters: temperature, strain and SoC/SoH.

Can fiber optics be used in high-value battery applications?

Finally, future perspectives are considered in the implementation of fiber optics into high-value battery applications such as grid-scale energy storage fault detection and prediction systems.

Are low-cost fiber optic sensors commercially viable?

A broader range of applications can become commercially viable as low-cost fiber optic sensors are commercialized in coming years. Three potential applications that we will discuss are passenger electric vehicles, heavy-duty electric trucks, and utility-scale battery energy storage.
