Continuous Monitoring System and Method for Detection and Localisation of the Cell-to-Ground Short Circuit for the Battery Cell Packs

The battery development and application surge in industry and academia is driven by the dual pressure of environmental pollution and energy shortage. To ensure safety, reliability and optimize the utilization of batteries as an energy storage system, a wide variety of approaches, health indicators and condition assessment methods and safety policies are available nowadays. This paper presents the approach for the detection and localisation of the cell-to-ground short-circuit that is a common potential issue in battery packs. The method is supplemented with the developed measurement and data acquisition system which is used for experimental validation. Moreover, the starting premise is validated in the simulated environment as well.
