In the battery pack, to safely and effectively manage hundreds of single battery cells, the cells are not randomly placed in the power battery shell but orderly according to modules and packages. The smallest unit is the battery cell. A group of cells can form a module. Several modules can be combined into a package.
Neutral wires take the used electricity from the load and bring it back to the power supply. To summarize: the hot wire carries electricity from the power supply and takes it to the load (lightbulb).
It is not recommended to connect a neutral line directly to a power outlet. However, you could disconnect the neutral line and use the earth to carry the current back to the power company, but only with a very little amount of current.
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:
The power company provides a common neutral line that is shared between all 3 lines. This neutral line is grounded to earth at the substation. Each house gets one phase of power and is connected to this neutral line.
Battery cells, modules, and packs are different stages in battery applications. In the battery pack, to safely and effectively manage hundreds of single battery cells, the cells are not randomly placed in the power battery shell but orderly according to modules and packages. The smallest unit is the battery cell. A group of cells can form a module.
Why is the Neutral Wire So Important?
The line drawn from the neutral point of transformer is called null line, or neutral wire, whose main function is to connect single-phase load, transmit single-phase current and three-phase unbalanced current, and reduce the neutral point potential drift of load. In TN-C TN-C-S, N-wire can also protect the ground connection and zero connection.

What Does the Neutral Wire Do?
In a live circuit, a neutral wire is always carrying electrical current unless a switch controls it. This means that if someone were to touch or ground out the neutral wire, they stand a good chance of being shocked with a substantial amount of voltage. According to the National Electrical Code, the neutral wire is the "grounded conductor ...

The function of the neutral conductor is to enable separate use of each phase and each phase can be used as an individual 230Vac supply. The neutral is also connected to a metal spike driven into the ground, the so-called earth spike. In this way, the potential of the earth equals 0 Volt. This connection is called earth.
