The basics of short circuits in power electronics systems
Short circuits can occur in both battery-powered and electrical mains-powered systems. (Source: GKV- stock.adobe ) When a short circuit occurs, resistance quickly reduces and a large volume of current flows through an unexpected pathway. Depending on the strength of the current, this can cause crackling, smoke, and flames—this makes a short …
Current flow in batteries?
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

Battery Pack Short Circuit
The circuit is completed and short circuits the system through a resistance of 0.1m-Ohm. As a high current passes through all the cells in the module, the cell temperature rises and quickly attains the trigger temperature for thermal runaway and gas venting. The switch is opened to disconnect the electrical circuit as the cell is now dead.
