SENSOR project overview video
Under the ARPA-E Advanced Management and Protection of Energy-Storage Devices (AMPED) program for advanced battery management systems, PARC and LG Chem Power (LGCPI) are developing SENSOR (Smart Embedded Network of Sensors with an Optical Readout), an optically based smart monitoring system prototype for battery packs. The system will use fiber optic sensors embedded inside Lithium-ion battery cells to measure parameters indicative of cell state online, such as state-of-charge (SOC) and state-of-health (SOH). SENSOR will leverage PARC's low-cost, compact wavelength-shift detection technology and intelligent algorithms to enable effective real-time performance management, optimized battery design, and improved safety. While SENSOR is initially targeting batteries for hybrid and electric vehicles (EVs), it will be extendable to battery systems for other challenging domains such as aircrafts, satellites, grid storage, and military vehicles. This video gives an overview of the project, the underlying enabling technologies, and the various possible spin-off applications.
