Quick takeaway: Cell → Module → Pack. Each step increases voltage/capacity, adds safety features (like BMS and thermal control), and improves serviceability. What Is a Battery Cell? The battery cell is the smallest functional unit—the core source of stored energy. Through electrochemistry, it converts chemical energy into electrical energy.
A lithium-ion battery pack is the largest and most complex assembly in the hierarchy of battery systems. It consists of multiple modules arranged in a specific configuration to meet the voltage and energy requirements of a particular application.
A modular battery pack takes the concept of modularity to the next level by incorporating interchangeable and stackable battery modules. Each module contains a set number of battery cells, and these modules can be added or removed as needed to adjust the pack's capacity or voltage.
When multiple cells are connected in series within a battery pack, the total voltage of the pack is the sum of the individual cell voltages. What is a Lithium-ion Battery Module? A lithium-ion battery module is a group of interconnected battery cells that work together to provide a higher level of voltage and capacity.
