Sandia-Developed Precision High Power Battery Tester Earns R&D 100 Award

R&D Magazine has recognized Sandia National Laboratories researchers’ work in developing innovative battery testing with the annual R&D 100 Award.

As principle investigator of the Precision High Power Battery Tester, Dr. Summer Ferreira was presented with the R&D 100 Green Tech Special Recognition Award.

The PHPBT uses high-precision charge/discharge test measurements at up to 200A current to capture electrochemical measurements such as coulombic efficiency with greater accuracy than was previously possible at currents applicable to EV and stationary storage applications. The goal is to detect minute signs of battery degradation earlier than previous testing, providing insight into a battery’s long-term capabilities and enabling engineers to better select feasible technologies from those needing more development.

With support from the Dept. of Energy’s Office of Electricity (DOE OE) and ARPA-e, PHPBT research was done in conjunction with Arbin Instruments, Ford Motor Company, and Montana Tech. Arbin has since commercialized the PHPBT technology.

R&D Magazine presents the annual R&D 100 awards to honor the year’s 100-most innovative technologies as selected by an independent panel of more than 70 judges.
