Experimental Observation • Chen’s model works OK compared with test<strong>in</strong>g data. – Under constant temperature and discharge rate • Rate effect and temperature effect are important to consider Reference: L. Gao, S. Liu, and R. A. Dougal, “Dynamic lithium-ion battery model for system simulation,” IEEE Trans, Compon. Packag. Technol., vol. 25, no. 3, pp. 495- 505, Sep. 2002 Impact of discharge rate Impact of temperature © 2009 ANSYS, Inc. All rights reserved. 6 ANSYS, Inc. Proprietary
Suggested Modification by Gao • The discharge history is sensitized to rate of discharge and temperature through rate factor and temperature factor Chen’s model Gao’s model Rate factor Temperature factor Reference: L.
