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 recent update video describes some exciting results over the project’s first half focused on cell-level state features detectable, initial SOX algorithm development, low-cost optical readout development, and early validation test results. These have paved the way for recently initiated module-level validation tests and more detailed cost-performance modeling studies.
This earlier video offers an overview of the problem, and an introduction of the project, the underlying enabling technologies, and various possible spin-off applications.
