The continuous development of science and technology and the continuous expansion of application fields, lithium battery as a type of battery with high performance and high energy density, it is widely used in various fields such as electronic equipment, electric tools, electric vehicles, etc. When customizing lithium battery pack, Configuration (Configuration) is a crucial part, which directly affects the performance, safety and stability of the battery pack. This article will discuss the importance of lithium battery pack when customizing Configuration and analyze the influence of different Configuration on battery pack performance.

I. The Meaning and Function of Configuration

1. Configuration (Configuration):

   • Configuration refers to the combination mode of single batteries in lithium battery pack, including series and parallel modes, which determine the total voltage, total capacity, total output power and other parameters of the battery pack.

2. Function:

   • Configuration directly affects the performance and characteristics of lithium battery pack. Reasonable Configuration can improve the efficiency, safety and stability of battery pack.

II. Impact of Configuration on lithium battery pack performance

1. series Configuration:

   • series Configuration connects multiple single cells together in the way of connecting positive and negative poles, increasing the total voltage of the battery pack.
   • Advantages: The total voltage and energy density of the battery pack are improved, which is suitable for application scenarios requiring high voltage output.
   • Disadvantages: once the single battery fails, it may affect the work of the entire battery pack.

2. Parallel connection Configuration </strong>:

   • parallel Configuration connects multiple single cells together in parallel in the way of connecting positive and negative poles, increasing the total capacity and output power of the battery pack.
   • Advantages: the total capacity and output power of the battery pack are improved, which is suitable for applications requiring high capacity output.
   • Disadvantages: it may increase the internal resistance of the battery pack and affect the charging and discharging efficiency of the battery pack.
