Electrochemical Impedance Spectroscopy (EIS) techniques are useful tools for being able to look at the 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 a method of undertaking EIS measurement on-line without the use of additional equipment by manipulating the earth leakage monitoring circuit to generate low frequency excitation signals to analyse a battery system connected to a dc/dc converter. This paper describes the methodology and presents some experimental results compared with off line EIS results generated with more traditional EIS equipment under the same conditions to illustrate the concept.
