6 FAQs about [Short circuit battery pack]

What is a battery internal short circuit (ISCR)?

The battery internal short circuit (ISCr) is one of the major obstacles that impede the improvement of the battery safety. Although most of the ISCr incidents only lead to the loss of battery energy and the decline of the battery performance, some of the ISCr incidents do result in the battery thermal runaway accidents (4).

What is the difference between a normal battery and a short-circuit battery?

The internal temperature of the short-circuit battery begins to rise first, and when it reaches 100 °C, the battery voltage shows slight fluctuations, and the external temperature starts to rise rapidly. In contrast, the internal and external temperatures of a normal battery begin to rise only after the voltage has dropped significantly.
