Detecting Cell Internal Short Circuits. Once the battery pack has been assembled from multiple cells in series and parallel the detection of an internal short circuit in one of the cells will be very difficult. The challenge is detecting it, shutting the pack down and ensuring anybody in the vicinity can be warned and get away.
Lithium battery has become the main power source of new energy vehicles due to its high energy density and low self-discharge rate. In the actual use of the series battery pack, due to the internal resistance and self-discharge rate of batteries and other factors, inconsistencies between the individual cells are unavoidable.

A battery pack includes a battery pack case, a battery pack connected in series and parallel, a battery management system (BMS), a wiring harness (strong & weak current), strong current components (relays, resistors, fuses, Hall sensors), etc. 2. Why are Pre-Charge Relays and Pre-Charge Resistors Added to the Battery Pack Components:
In a series connection, the positive terminal of one battery is connected to the negative terminal of the next battery, which increases the voltage of the pack. In a parallel connection, the positive terminals of all batteries are connected together, as are the negative terminals, which increases the capacity of the pack.
A battery pack is essentially a collection of individual batteries connected together in series or parallel to increase voltage or capacity. The wiring diagram for a battery pack outlines how these connections should be made. One key aspect to understand is the difference between series and parallel wiring.
