| Abstract |
Electrochemical Impedance Spectroscopy (EIS) techniques are useful tools for being able to look atthe characterisation of batteries under different conditions and/or with different material components.However, EIS analysis is mostly undertaken offline with bespoke equipment. This paper describes amethod of undertaking EIS measurement on-line without the use of additional equipment bymanipulating the earth leakage monitoring circuit to generate low frequency excitation signals to analysea battery system connected to a dc/dc converter. This paper describes the methodology and presentssome experimental results compared with off line EIS results generated with more traditional EISequipment under the same conditions to illustrate the concept. |
