6 FAQs about [Energy storage charging pile explosion temperature]

What happens if a combustible gas explodes in a battery module?

Considering that gas explosion may cause thermal runaway of battery module in the actual scene, the existence of high-temperature zone may be longer and the temperature peak may be higher. After the combustible gas got on fire, the gases volume expanded by high-temperature compresses the volume of the surrounding gases.

How hot does a battery pile need to be?

The critical ambient temperature that allows the self-heating ignition of battery piles ranges from 135 °C to 192 °C, which decreases with SOC or battery pile size increases. The good linear fit in the Frank-Kamenetskii analysis indicates the rationality and validity of the classical self-ignition theory for battery piles.

What is the temperature at the end of an explosion?

At the end of the explosion, the highest temperature inside the container of the explosion can exceed 2000K. The area of high-temperature at 343K and above is wider at the low altitude layer of 0.4m. The duration of overpressure is only about 1 second.
