Solid State Battery Pouch Cell Hot Press Formation Machine
Equipment Function and Principle
This equipment is used for cell formation and hot pressing, replacing existing formation fixtures and hot press machines. The main operations include manually loading the material from the preparation tooling into the hot press formation fixture, automatic heating, pressing, and formation, and then manually unloading from the hot fixture after the formation process. This equipment is suitable for specific battery production (user provides drawings), compatible with cells with or without airbag indentations, and consists of two sets of hot press fixtures.
System Features
1. The system adopts an intelligent and user-friendly design with multi-stage pressure adjustment, allowing pressure change over time.
2. One-click pressure setting: input the length and width of the cell, and the program automatically generates pressure and stress.
3. Temperature is controlled by a temperature module, with real-time data feedback via K-type thermocouple to PLC. Temperature rises from ambient to 90°C in less than 45 minutes with an error margin of ±1.5°C.
4. The temperature control module monitors and controls heating. Heating automatically starts when below the set temperature and stops when above. A second-level high-temperature alarm stops the entire fixture's heating and formation process if the temperature exceeds the maximum, prompting system alarms for manual intervention. Multiple monitoring pathways ensure redundancy, with at least two parallel monitors providing independent alarm signals in case of heating issues.
