As a professional lithium-ion battery pack assembly equipment and battery testing equipment supplier, Xiamen WinAck Battery can provide mature lithium-ion battery incoming inspection solutions. 1. Cylindrical Battery cell sorting machine.
Introduction to the assembly of battery packs and their inspection. The smallest unit of a battery is called a cell. The three common shapes of cells are cylindrical, prismatic, and pouch. The state in which the cells are connected is called a module, and the state in which the modules are connected is called a pack.
Batteries go through an acceptance inspection before they are put together into modules and packs. This is because things like vibrations during shipping and even the passing of time can cause batteries to defect. It is necessary to keep the electrodes and enclosure (case), insulated from each other.
The general incoming inspection protocol focusing on MCT is shown in Figure 2, whereby the specific electrical test protocol applied consecutively with the five cells of each batch and involving EIS, DC-IR, and pOCV measurements is presented in Table 3 in aggregate form. Schematic representation of the proposed incoming inspection. Table 3.
The MCT measurement setup and the interconnection board are consequently suitable for the tests, as no particular measurement deviations are to be expected due to the setup itself. The delivery condition visually observed and electrically determined is presented, before the results of the MCT-based electrical incoming inspection are presented.
The authors assume that the cell manufacturer of their test specimens initially took a conservative approach to ensure compliance with the product specification and then carried out optimizations to save on raw materials and reduce costs, as an adjustment of the silicon and nickel content was revealed.
The state in which the cells are connected is called a module, and the state in which the modules are connected is called a pack. There are also packs without modules, such as "Cell to Pack". Cells produced at the cell production factory are shipped to the module production factory after undergoing a shipping inspection.
