Research abstract
We propose in conjunction with Dr. M.A. Alim of Alabama A&M University to measure through small signal ac voltage injection and frequency response analysis the internal complex impedance of the target battery over various charge/discharge rates, temperature, and number of cycles. Correlation will be observed between the impedance variations and state of charge and state of health of the target battery. A simplified algorithm will be developed that will provide a high level of confidence and accuracy with minimal impact on battery operation and load. Hardware modifications will be proposed to provide small signal ac injection and response measurements for the target battery.
