MMAE Seminar - Effect of Fast Charging Lithium-Ion Batteries

Event Date 

January 14, 2015 - 3:30pm to 4:30pm

Location 

10 W. 32nd Street
Engineering 1 Building
Crawford Auditorium, Room 104

Description 

Department of Mechanical, Materials, and Aerospace Engineering (MMAE), IIT's Wanger Institute for Sustainable Energy Research (WISER), and Robert W. Galvin Center for Electricity Innovation will co-sponsor a joint lecture featuring Dr. Ira D. Bloom. Dr. Bloom, Manager at Electrochemical Analysis and Diagnostics Laboratory of Argonne National Laboratory, will present "Effect of Fast Charging Lithium-Ion Batteries." This seminar is part of the "Seminar Series on Challenges and Opportunities in Energy." 

Abstract

With further vehicle electrification, consumers may expect battery charging to take about the same amount of time that refueling an internal-combustion-engine-powered vehicle current does at a service station. This "fueling" does not have to be a full charge, but can be a partial charge. The Fast-Charge Test, in the USABC EV Manual [1], was designed to measure the impact of charging a battery from 40 to 80 % SOC at successively higher rates, starting from about twice the overnight rate. Since the manual was written for nickel-metal hydride technology, this test may have to be adjusted for the higher-performing, lithium-ion cells. The high charge rates used may introduce new degradation modes, causing the performance of the battery to decline faster than expected. The performance and post-test analysis results will be discussed.
