PARC and LG Chem Power Advance Development of SENSOR to Improve Battery Performance
14 July 2015 | The Battery Show News
PARC, a Xerox company, has announced the final stages of development with LG Chem Power, having successfully transitioned to module-level testing of SENSOR, a next-generation fiber-optic sensing battery management system, with specific initial focus on hybrid and electric vehicles (xEVs).
The SENSOR system uses PARC’s compact wavelength-shift detection technology, along with its machine learning and sensor network expertise for effective real-time performance management and optimized battery design to enable cheaper, lighter and more reliable battery packs. Capabilities range from accurately inferring cell state and health information to predicting remaining life. The resulting commercial xEV-grade battery module with embedded optical sensors and readout unit will undergo industry-standard validation.
Sensors Could Make Electric-Car Batteries Smaller and Cheaper
ARPA-E says better sensors and controls could allow automakers to cut battery size by 20 to 50 percent.

"Electric-vehicle battery packs could shrink 20 to 30 percent, and make electric vehicles more affordable, if new sensors were developed to monitor the cells in a pack, according to the U.S. government’s Advanced Research Projects Agency for Energy (ARPA-E). The agency says such sensors could have an even greater effect on hybrid gas-electric vehicle batteries, causing them to shrink by half.
Better sensors could tell what’s happening inside each of the hundreds of cells that make up an electric vehicle’s battery pack, allowing automakers to safely store more energy in them. A $30 million ARPA-E program that’s been underway for about a year is seeking to develop the necessary technology."
$43 Million for Transformational Storage Projects to Advance Electric Vehicle and Grid Technologies
2 August 2012 | announcement
"The Department of Energy today announced that 19 transformative new projects will receive a total of $43 million in funding from the Department’s Advanced Research Projects Agency-Energy (ARPA-E) to leverage the nation’s brightest scientists, engineers and entrepreneurs to develop breakthrough energy storage technologies and support promising small businesses..."

Advanced Management And Protection Of Energy-Storage Devices (AMPED)
- Lead organization: PARC
- Description: Smart Embedded Network of Sensors with Optical Readout (SENSOR). Palo Alto Research Center will develop new fiber optic sensors that are inserted into battery packs to monitor and measure batteries during charge and discharge cycles. These compact fiber optical sensors will measure the battery’s health while in use to avoid degradation and failure.
- Funding: $4,018,960
ARPA-E awards $43M to 19 energy storage projects to advance electric vehicle and grid technologies
2 August 2012 | Green Car Congress
"The US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) has selected 19 new projects to receive a total of $43 million to develop breakthrough energy storage technologies and support promising small businesses...
Unlike other Department of Energy efforts to push the frontiers of battery chemistry, AMPED is focused on maximizing the potential of existing battery chemistries. These innovations are intended to help reduce costs and improve the performance of next generation storage technologies, which could be applied in both plug-in electric and hybrid-electric vehicles."
