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.
Depending on the area of application, identifying deviations in the electrical behavior of the battery cells under test can be essential for downstream assembly processes like cell matching and algorithm adaptations of the battery management software.
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.
The visual inspection of the cells showed a homogeneous quality, independent of the batch. No abnormalities like dents, cracks, or similar were found. The cells of all intermediaries were insulated with transparent shrink wrap of varying material and design.
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 principle is shown in the image below: a short laser pulse creates an ultrasound wave in the battery. The ultrasound wave travels through the cell, with sites that lack or have insufficient electrolyte wetting conducting less or no ultrasound, while sites that are well wetted conduct ultrasound.
