energy storage system short-circuit current

What is ISC & external short-circuit fault in battery systems?

Internal short-circuit (ISC) fault in battery systems is considered one of the most severe problems that can result in thermal runaway and fire [4, 5]. Therefore, studying detection methods of ISC and external short-circuit faults of batteries is very important to ensure safety in the lives of people and to avoid major accidents.

Does a large SoC inconsistency exist in a battery module?

To test if a large SOC inconsistency existed in the battery module, the proposed ISC fault-diagnosis method based on voltage cosine similarity was investigated if it could still respond to a simulated ISC fault without a false alarm due to inconsistency.

How do you determine a short-circuit fault in a battery?

Comparison of the similarity between these two-dimensional vectors implies measurement and comparison of the similarity of the voltage response of the adjacent battery cells under the same excitation at the same time. The short-circuit fault in the battery can then be diagnosed using the similarity of response.

What happens when a battery cell experiences an ISC fault?

When a battery cell in the module experiences an ISC fault, the similarity between the voltage response of the faulty battery cell and that of the adjacent battery cells decreases, which is reflected in the reduction in the cosine value of the vector angle. The flowchart of the proposed diagnosis method is shown in Fig. 7. Fig. 7.

What is a judgment condition in a series-connected battery module?

This method considers the relevant voltage between the adjacent cells as the judgment condition, which is not limited by the number of cells in a series-connected battery module, even if the number of cells increases as the voltage of each cell can be measured separately.
