Old bus batteries are getting new life as a backup power supply for Everett Transit.

BattGenie, a startup based in Austin, Texas and Seattle that focuses on energy storage and software to manage it, installed the system in January.

Everett’s not paying anything for the unit housed in a small shipping container on a corner of its Cedar Street lot. The tech hub gets to collect data and test its concept on an open-ended timeline.

The system uses old electric bus batteries from King County Metro that don’t have their full charge capacity.

But the batteries still hold energy. Combined with dozens of others, they have enough charge to power 10 homes for one hour, co-founder and CEO Manan Pathak said during a demonstration last week.

Venkat Subramanian

CTO, Chief Scientific Advisor, and Co-Founder

Prof. Venkat Subramanian is currently the Ernest Dashiell Cockrell II Professor of Mechanical & Material Science Engineering at the University of Texas, Austin.

His research interests include energy systems engineering, electrochemical engineering, computationally efficient algorithms for state-of-charge (SOC) and state-of-health (SOH) estimation of lithium-ion batteries, multiscale simulation, and design of energetic materials, kinetic Monte Carlo methods, model-based battery management system for electric transportation, and renewable microgrids and nonlinear model predictive control. Prof. Subramanian was awarded the Dean’s award for excellence in graduate study in 2001 for his doctoral research.

He is a Fellow of the Electrochemical Society and a past Technical Editor of the Journal of the Electrochemical Society. He was also the chair of the IEEE Division of the Electrochemical Society. His codes for Lithium-ion batteries are the fastest reported in the literature and his algorithm for solving index 1 nonlinear DAEs is the most robust compared to any other algorithm reported as of today.

Prof. Subramanian received his B.Tech. degree in Chemical and Electrochemical Engineering from the Central Electrochemical Research Institute (CECRI), Karaikudi, India, in 1997 and the Ph.D. degree in Chemical Engineering from the University of South Carolina, Columbia, SC, USA, in 2001.
