The number of electric vehicles is growing rapidly, and so are  retired batteries. The batteries are costly in production and  recycling. Handling retired EV batteries is thus important for both  the economy and the environment. DOE and CEC have funded multiple  projects to promote second-life EV batteries (SLBs) in storage  applications. However, deploying SLBs will encounter serious issues,  such as lifetime, cost, safety, liability, and regulations. This talk  will discuss the result of a recent CEC-funded project, including the  aging mechanism, charge/discharge methods, thermal management,  cell/pack balancing, energy management, policy, standards, and fire  codes related to energy storage systems using SLBs.?

Chris Mi received his B.S. and M.S. degrees from Northwestern  Polytechnical University, Xi’an, China, and Ph. D. from the University  of Toronto, Canada, in 1985, 1988, and 2001, respectively, all in  electrical engineering. He is a Fellow of IEEE and SAE, a  Distinguished Professor of Electrical and Computer Engineering, and  Director of Caili and Daniel Chang Center for Electric Drive  Transportation at San Diego State University. He was previously a  faculty member at the University of Michigan-Dearborn from 2001 to  2015, and an Electrical Engineer with General Electric from 2000 to  2001. He also served as the CTO of 1Power Solutions from 2008 to 2011,  and CTO of EV Safe Charger from 2021 to 2022.
