The structure of LFP modules mainly has a banding structure. Due to the high flexibility of banding modules, the quantity in series and parallel of lithium battery cells can be determined according to the demand of customers. Generally, Lithium Storage offers the following LFP modules:
Flexibility in series and parallel 50~302Ah lithium battery cells, 1P8S or 1P4S LFP modules are common types.
Heating pad is optional
Connector type and definition can be customized
For improving production efficiency, the positive and negative terminals of lithium-ion batteries have been upgraded from screw hole terminals to flat welding terminals. The new generation lithium batteries require welding equipment for battery connections. Sorting out the demand from the international market, many international customers still prefer to choose cells that can be connected by screws or bolts than flat welding terminals. The following points are pointed out by customers:
Due to the total pack or module needs to be replaced once one cell of the battery pack fails in the operation. As well as, there is a dimension limit on module size for different application cases from the local market, and there is low feasibility to use the same module to meet all pack requirements. Therefore, customers prefer cells with nut/screw terminals for the flexibility of pack installation.
However, Lithium Storage recommends customers select battery modules instead of cells because of the high structural stability and welding reliability of battery modules.
The banding module has high flexibility in production due to its structural characteristic.
lithium battery cells are connected by an aluminum busbar via laser welding.
Banding belt structure, the upper part is a steel belt and the lower part is a plastic belt.
M4 hole on the aluminum busbar is applied to fix sampling wiring.
