First, the production control of lithium battery MES

MES system will be connected with digital management from the incoming materials management of upstream lithium battery manufacturers to realize batch management of batteries, wire harnesses, flat tubes, boxes and BMS monitoring boards.

In the production process of MES system, first, the voltage, resistance, capacity and other items are strictly tested on line, so that MES system can be connected with battery testing equipment, and the testing situation can be recorded and fed back in real time.

In the process of battery grouping, multiple single batteries will be combined in series into a module. At this time, according to the requirements of assembly process, MES system associates the codes of all single batteries with a module to form a corresponding code association, and then MES system automatically generates and prints the module barcode and gives it to the module.

In the process of module assembly, MES system will carry out error prevention, binding and process control on the materials used in the module, and the codes of key materials such as wire harness and pole pieces used in the module are bound with the module codes. After the module is assembled, MES system tests the pressure difference, temperature and humidity of the module online.

In the final assembly of PACK, MES system combines multiple modules into a single box, and also records module codes, BMS monitoring board and other key material codes in real time, and also strictly monitors the screw torque in the assembly process.

After the battery pack is assembled, the quality of the whole lithium battery pack will be tested through various tests, such as insulation withstand voltage test, electrical performance test, air tightness test and EOL test. MES system is connected with these current test equipments to control and read test status and data in real time.

After all the assembly, inspection and testing are completed, the MES system generates the packaging barcode and automatically triggers the barcode printer to print the barcode. At this point, a complete lithium battery finished product was manufactured and officially rolled off the assembly line.

Second, summary

From the summary, we can see the important position of MES system in the whole lithium battery production process and the penetration ability of MES system in the lithium battery production process. MES system combines TS 16949 standard which emphasizes the fine management and digital control of lithium battery production, and presents various key data in the production process in a visual way. MES system will realize digital management of lithium batteries from many dimensions, such as material batch, process technology, quality control, sales and delivery, and market application. , so as to improve production efficiency, improve product quality and realize full traceability. Above, we only introduced MES system symbolically, which is the core management business in the later PACK production of lithium batteries.

Hefei Maisi Software focuses on IT information construction of manufacturing industry, including MOM system, MES system, WMS system, quality management system, electronic kanban, workshop logistics system, man-hour management system and production scheduling system.
