6 FAQs about [New energy battery high temperature warning]

How do we predict thermal runaway & early warning of lithium-ion batteries?

The thermal runaway prediction and early warning of lithium-ion batteries are mainly achieved by inputting the real-time data collected by the sensor into the established algorithm and comparing it with the thermal runaway boundary, as shown in Fig. 1.

What is thermal runaway warning technology based on lithium ion batteries?

Thermal Runaway Warning Technology Based on Lithium-Ion Battery Temperature Lithium-ion batteries can experience thermal runaway, which is characterized directly by a significant rise in internal temperature and indirectly by a rise in surface temperature.

How hot does a battery get?

The internal temperature of the battery is actually close to 100 °C when the surface temperature is 80 °C, at which point the SEI coating begins to decompose. When more heat is continuously accumulated, the battery’s risk of thermal runaway increases significantly.

Why is early warning important in battery safety risk management?

In addition to modifying intrinsic battery properties, early warning systems to detect battery failures are also vital in battery safety risk management. It is necessary to first analyze typical battery safety failure scenarios and then to select reasonable warning methods based on these scenarios.

What are the symptoms of a battery failure?

An internal battery failure symptom that is frequently observed is an excessively high internal temperature of the battery. When the battery’s internal temperature exceeds 90 °C and 130 °C, there is a risk of explosion and the possibility of thermal runaway. As a result, it is important to keep an eye on the battery’s interior temperature.

Why is a lithium-ion battery a good early warning device?

When more heat is continuously accumulated, the battery’s risk of thermal runaway increases significantly. The gadget demonstrates outstanding early warning performance for the unusually hot lithium-ion battery and has the advantages of high efficiency, convenience, and quick response.
