Challenge
The rising demand for lithium-ion batteries for new energy Vehicles (NEV) requires highly automated and reliable production. A critical step is the welding of cell connections, which determines the battery’s performance. Every weld point must be inspected, and the results must be fully documented. Since production lines often have more than 35 read/write positions, traditional RFID systems incur high costs. An efficient and cost-effective solution is needed.
Solution
TURCK's HF-bus mode-RFID ensures cost-effective traceability of production quality. When welding the cell joints, the test results are written directly to RFID tags attached beneath the product carriers. Thanks to the RF-bus mode, up to 32 read/write devices can be operated on a single RFID port of the TBEN-S2-2RFID-4DXP interface. This reduces the cost per reading position while maintaining production speed. The reading of RFID tags is triggered by inductive sensors. If a tag is not detected, the system automatically signals a faulty or missing data carrier to detect errors early on. The TBEN-S2-2RFID-4DXP interface connects RFID readers and sensors and communicates via Profinet, Ethernet/IP, or Modbus TCP with the controller—without any additional configuration effort. This ensures the solution remains highly flexible and easily scalable.
“Thanks to TURCK’s HF bus mode, RFID systems can be scaled efficiently and cost-effectively in battery production.”
