Semco SI RJ6903R is widely used for (micro) short circuit testing in winding, stacking, cell assembly and before liquid injection, which greatly improves the testing efficiency of the production line; it can be applied to the testing of different types of battery cells for Li-ion batteries, nickel-hydrogen batteries, supercapacitors, sodium-ion batteries and other products

• Manufacturing processes for battery cells have a high degree of inherent variation, requiring a more advanced and robust BMS. The BMS must compensate for any underperforming cells in a module or pack by actively monitoring and balancing each cell’s state of charge (SOC). A battery pack design can have infinite combinations of good and bad cells, and will be subject to a huge range of environmental conditions. These variations and usage scenarios necessitate Battery Pack simulation for development and qualification of effective Battery Management Systems.
