Purpose and goal

The purpose of this project was to investigate a few NPS sensor probe and readout unit configurations suitable for large volume low cost fabrication. The project fulfilled its overall goals. Different optical fiber sensor probe configurations, including fiber type, diameter and NPS sensing structure, were evaluated. Optical components were mapped, and the most suitable ones tested. In addition, a prototype was developed and validated, including fiber sensing probe, hardware and preliminary software interface.

Expected results and effects

The direct result of this project was a prototype of the complete NPS battery sensor, including sensor probe, optical read out unit and software suitable for low cost fabrication. In addition, a prototype for multiple sensor probing was constructed. The outcomes of this project have increased the TRL level of Insplorion’s battery sensor and brought it closer to commercialization. They have also motivated the continuation of the joint development by applying for another Smartare Elektroniksystem full scale project.

Planned approach and implementation

The project was a close collaboration between Insplorion and RISE where RISE performed most of the testing of the optical readout unit and contributed with custom made optical fibers. Insplorion performed development on the NPS sensing structure, performed laboratory test with the developed sensor probes and developed the necessary data analysis algorithms and software. The successful implementation of the project was achieved through weekly web meetings and monthly visits, which facilitated the communication between the partners.
