CYLINDRICAL BATTERY PACK SORTING & WELDING EQUIPMENT

Individual lithium-ion cells are connected in series to a module. We offer assembly platforms for a precise positioning and secure fixing of battery cells to each other in a module. The machine tests and groups the cells to achieve a High-Performance Battery Pack. This solution is focused on a flexible production of cylindrical cell battery packs.
