Substitute internal short circuit experiments validate the proposed algorithm at pack level. The proposed approach detects the fault of internal short circuit efficiently and accurately, having great potential to be applied in the fault diagnosis of battery pack for large scale energy storage systems. 1. Introduction
An internal short circuit (ISC) detection method for lithium-ion battery is proposed. The ISC detection algorithm is addressed from number theory and circuit topology. The algorithm can detect ISC based on signals extracted from Ampere Meters. The algorithm can detect ISC with a resistance of smaller than 10Ω within 15 s.
Micro-short circuit (MSC) of a lithium-ion battery cell is a potential safety hazard for battery packs. How to identify the cell with MSC in the latent phase before a thermal runaway becomes a difficult problem to solve. We propose a diagnosis method to detect the MSC according to the remaining charging capacity (RCC) variations between cells.
A quantitative diagnosis method for the micro-short circuit fault of lithium-ion batteries is proposed. The remaining charging capacity is estimated using the charging cell voltage curve transformation. Estimated the leakage current and micro-short circuit resistance with low computational complexity.
Internal short circuit is one of the unsolved safety problems that may trigger the thermal runaway of lithium-ion batteries. This paper aims to detect the internal short circuit that occurs in battery pack with parallel-series hybrid connections based on the symmetrical loop circuit topology.
Internal short circuit is a very critical issue that is often ascribed to be a cause of many accidents involving Li-ion batteries. A novel method that can detect the Internal short circuit in real time based on an advanced machine leaning approach, is proposed.
