The design and structure of the battery module can be customized according to needs, such as size, shape, capacity, and function. The function of the battery module is to improve the combination density and reliability of battery cells while facilitating the assembly, connection, and management of battery packs.
The battery cell refers to the most basic component of the battery. Usually, an electrochemical device is enclosed in a metal casing. It is a unit that stores and releases electrical energy, converting chemical energy into electrical energy through chemical reactions.
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.
A battery module is a group of individual battery cells connected, usually with their management system. On the other hand, a battery pack consists of one or more modules, along with additional components like casing, connectors, and thermal management systems. What is a cell in a battery pack?
Battery Pack: Incorporating modules and additional components like circuits, sensors, cooling systems, and packaging materials, a battery pack’s primary role is to provide power for specific applications such as electric vehicles (EVs) or renewable energy storage systems. In essence: Cell: The basic energy storage unit.
Individual cells are too small to power large devices, while entire battery packs are cumbersome to handle and maintain. Modules, however, strike the right balance, making it easier to design, assemble, and maintain complex energy storage systems. Part 2. Battery module composition
