N2 - The demand for space resolved temperature monitoring and collection of other in-cell data is rising as lithium-ion batteries gain more and more importance, especially for high power applications like power tools or electric vehicles. Safety issues and fast aging are still unresolved problems. To face these, sensor matrices that provide the possibility to collect multiple sensor data at the same time are recently under investigation by various research groups. The problem of data transmission from in-situ sensors to external battery management systems however is yet to be solved, especially when it comes to laminated pouch cells. As a possible solution a method is developed for capacitive coupling in combination with frequency multiplexing to be able to read out multiple sensor data without additional wiring. The presented concept is designed such that it can be minimized and digitized in next steps and therewith fully integrated into the cells during production.
