6 FAQs about [Energy storage battery internal detection]

How is ISC detected in a battery?

The ISC detection in this stage is usually realized by voltage-related characteristics. Middle ISC. With the development and evolution of ISC, the ISC resistance gradually decreases. The discharge current of ISC is larger due to the low resistance of ISC, which leads to the evident decrease of battery voltage.

Did battery management system detect a battery defect?

Investigations revealed that the failure was attributed to an internal defect specifically related to an unusual deposition of lithium metal and dendrite growth within the battery cells during operation. However, in this incident, it appears that the battery management system (BMS) did not detect the battery defect that led to the fire.

What are the technical routes used in battery research?

At present, the main technical routes are as follows: (1) The battery models (e.g., electrochemical model, electrothermal coupling model, and ECM) are established to predict the voltage and temperature of the cells . The measured voltage or temperature of each cell are then compared with the predicted value of the model.

Does automatic battery inspection increase the storage burden of EVs?

At present, many EVs are equipped with automatic battery inspection system, that is, after the EV stops, the BMS is opened periodically (such as 20 h) to detect the voltage and temperature of the cell. Each time the inspection system is turned on, the duration is merely tens of seconds, and thus, it will not increase the storage burden of the BMS.

How does specific energy affect a battery?

With the increase of the specific energy of the battery system, the electrode material of LIB becomes thicker and the diaphragm becomes thinner, and the probability of ISC increases. According to the statistics in Ref. , 52% of battery fire accidents are caused by ISC, and 26% of battery fire accidents are caused by external SC.
