Influence of short circuit on electrochemical cell and its replacement equivalent scheme

Abstract

This research examines the effects of a short-circuit on an internal substitute equivalent electrochemical cell scheme on a deeper level. A LiFePO4-based cell in this example. Targeted short-circuiting of electrochemical cells and the method of analysis of measurement data are described in this article. The paper uses the R2C2 replacement equivalent scheme. The article illustrates the change in these passive elements as a function of the electrochemical cell’s SOC (State of charge). These shortcuts were made in 2 variants. In the first case, the electrochemical cell was charged to 50% SOC and in the second case, it was fully charged to 100% SOC.
