Energy storage refers to the process of storing energy through media or devices and releasing it when needed. Energy storage runs through all aspects of new energy development and utilization. It is not only an important guarantee for national energy security but also a major driving force for emerging industries such as electric vehicles, with significant strategic value and promising industrial prospects.
1. Process Introduction
The battery energy storage production line is mainly divided into three stages: electrode preparation, cell assembly, and testing assembly.
（1）Electrode Preparation: This stage involves the production of cathode and anode electrodes. The primary processes include mixing, coating, and die-cutting. Mixing combines battery raw materials to form a slurry, coating applies the slurry onto the anode and cathode foils, and die-cutting involves cutting the foils to create electrodes with welded tabs. Finally, the rolled electrodes are transported to the next stage.
（2）Cell Assembly: This stage combines two rolled electrodes into a single battery cell. Processes include winding, welding, casing, and electrolyte injection. Winding rolls the two electrode layers into a single battery core, welding attaches the battery core to the electrode foils, casing installs the processed cell into a fixed outer shell, and electrolyte injection fills the battery shell with electrolyte.
（3）Testing Assembly: This final stage involves formation, capacity testing, and packing. Formation places the batteries in specialized containers for aging. Capacity testing assesses the batteries’ performance and safety. Finally, in the packing stage, individual qualified batteries are packaged into battery packs.
2. Customer Story
This project is used in the welding section of battery cell production. The main station uses Omron NX502-1400PLC, which uses the EtherCAT communication interface of the main body to communicate with ODOT C series remote IO (CN-8033).
The DI digital input modules are primarily used for button and fixture position sensors, material detection, cylinder magnetic switches, vacuum gauge inputs, access control sensors, etc. The DO digital output modules are mainly used for cylinder actions, vacuum nozzle actions, lighting control, motor rotation, access control, etc. The communication module CT-5321 is connected to a rangefinder for monitoring welding distance, a wind speed meter for dust removal wind speed detection, and a welding machine’s RS232 port for collecting important welding parameters.
