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.
A common type of short circuit occurs when the positive and negative terminals of a battery or a capacitor are connected with a low- resistance conductor, like a wire. With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.
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.
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.
The inconsistent behavior among batteries and heat transfer between them are considered the main reasons why the duration of a short circuit in a module is typically shorter than that of an individual cell. As Fig. 16 (E) and (F) demonstrate, failed cells exhibit higher surface temperatures compared to functioning ones.
Under the same conditions, the duration of a short circuit in a series module are all less than those of a short circuit in a single cell.
Short Circuiting a Battery: What Happens Next
Short circuiting a battery means excessive current follows an unintended path, due to an abnormal connection with little or no impedance. This condition allows an excessively high current to flow with little resistance. An uncontrolled surge of energy can damage the circuit, and result in overheating, skin burns, fire, and even explosion.
