A battery module is a structural and electrical unit formed by grouping together multiple battery cells that are electrically connected in series and/or parallel. It serves as an intermediate building block between individual cells and the complete battery pack, providing a balance between scalability, safety, and ease of integration in applications such as electric vehicles (EVs), stationary energy storage systems (ESS), and industrial equipment.
Role in a Battery System:
Multiple modules are combined to form a battery pack
Enables modular design, simplifying manufacturing, maintenance, and replacement
Supports thermal isolation, electrical safety, and system diagnostics
