Different DC arc fault detection, warning, and protection methods that can be used for battery systems are summarized and compared. The future trends in DC arc research in battery systems are explored, including mechanism exploration, model simulation, detection methods, early warning strategies, and protection technologies.
Battery management system is used to measure arc signals, fuse multidimensional arc information, and identify arc processes in battery systems. However, the arc detection and warning technology has high requirements for the sampling accuracy and calculation speed of the battery management system.
Currently, DC arc fault detection methods are provided in DC microgrid systems , PV systems [10, 15], aircraft DC systems and DC distribution systems . These detection methods can also be applied to battery systems, which is extremely useful for studying arc faults in battery systems.
The physical and electrical signals of DC arcs in battery systems are unstable and nonlinear. Artificial intelligence-based methods are crucial for addressing the complex signal issues of arcs and improving detection accuracy, making them a trend in future arc detection research.
In addition, a battery system failure index is proposed to evaluate battery fault conditions. The results indicate that the proposed long-term feature analysis method can effectively detect and diagnose faults. Accurate detection and diagnosis battery faults are increasingly important to guarantee safety and reliability of battery systems.
Arc faults in battery systems can also be detected by extracting the characteristics of electrical signals. Indirect arc observations using electrical signals can be roughly divided into two categories: the direct statistical method and the signal transformation method.
