Stacked energy storage lithium batteries refer to lithium battery packs formed by combining multiple units, with the cell type mostly being lithium iron phosphate. This type of energy storage lithium battery pack can enhance the overall capacity and output power of the energy storage system.
Stacked energy storage lithium battery packs are usually composed of components such as BMS (Battery Management System), EMS (Energy Management System), battery modules, external cables, and enclosures. Their advantages generally include:
Large capacity: The battery pack increases its overall capacity by stacking multiple battery modules, making it suitable for high-power application scenarios;
High output power: Through series and parallel connections, it can meet higher load power requirements;
High space utilization: Stacked batteries occupy relatively little space, making them quite practical for narrow space scenarios.
However, the current technology of stacked energy storage lithium batteries has relatively high thresholds. A more advanced BMS is required to improve the stability of the lithium battery pack. Meanwhile, the manufacturing cost of high-voltage stacked battery packs—including technical and material costs—is relatively high, and there are also strict requirements for cell consistency.
