6 FAQs about [The principle of battery short circuit]
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 causes a battery to short circuit?
This usually happens during some-or-other incident, but it can also be the result of human carelessness or malice. Short circuiting a battery deliberately, or accidentally connects the positive and negative battery nodes, forcing them to be the same voltage. The result, as Wikipedia puts it aptly, is a connection with almost no resistance.
What is a short circuit in a battery cell?
By short circuit we mean an electrical short circuit, a very low resistance path between the positive and negative sides of the cell or cells. A short circuit can be inside a battery cell or external to a battery cell. There are a number of things that can cause an internal short circuit within a battery cell.
What determines a battery's short circuit current?
To recap: the short circuit current is a function of several variables but is mostly determined by the nominal voltage and internal series resistance. If the positive and negative terminals are connected by a wire then the battery is by definition shorted. What the voltage of the battery is does not really matter.
What happens if a battery does not have a short circuit?
Firstly, without external short circuit protection, the battery passes a great current for a long time leading to a rapid rise in temperature, which triggers the internal side reaction or even thermal runaway, generating a large amount of smoke, which triggers combustion under the action of electric sparks, as in the result of test 1.
What is a short circuit?
Outside of formal circuit analysis, there is no universal definition of short circuit in absolute terms of voltage, current or resistance. In most contexts, a short circuit is not a mathematical function or limit, it's just a general term for a type of failure or behavior.
