End of line test lithium battery machines by CMWTEC deliver intelligent, automated quality assurance for lithium-ion, lithium polymer and alkaline battery cells at the final stage of production. As the demand for lithium battery technology continues to grow across electric vehicles, energy storage and consumer electronics, reliable end of line testing is critical to ensuring every cell meets the highest safety and performance standards.
CMWTEC’s lithium battery EOL test stations are universal intelligent systems designed to meet the highest standards of ergonomics, working environment safety and production efficiency. Each test station features a clearly structured operator panel with software-controlled test procedures, allowing multiple test parameters to be monitored and controlled from a single interface – without touching the battery.
Our lithium end of line test equipment supports a wide range of test procedures including electrochemical impedance spectroscopy (EIS), open circuit voltage (OCV), capacity testing and safety verification. The semiautomatic EIS test machine additionally functions as an advanced cell classifier, enabling precise grading and sorting of lithium pouch and prismatic cells for quality-critical applications.
All CMWTEC lithium battery test stations can be configured as standalone units or integrated into existing production lines. Custom solutions are available for specific cell formats, test requirements and production volumes.
Manufactured in Runkel, Germany – intelligent testing for the battery technologies of tomorrow.
With German engineering at its core, our modular concept turns individual machines into a scalable production system that grows with your requirements.
You can start with a compact setup and integrate additional modules whenever your capacity, processes or product portfolio change. This keeps your investment efficient today and your production flexible for tomorrow.
Our modular machines can be combined into flexible production lines and various machine set-ups – exactly as your process requires. In addition to proven setups, we also support individual requests and tailor-made solutions for your specific needs.
Whether you choose an established combination or develop your own – we’ll help you build the perfect system.
CMWTEC offers complete solutions for battery production—ranging from stand-alone machines and fully automated lines to advanced testing equipment and smart handling systems. Our modular approach enables flexible configurations and seamless integration into existing processes. With the DataManager software, we also provide digital tools for process control, traceability, and production data management. From assembly to end-of-line testing, CMWTEC delivers efficient technology for the entire battery production workflow.
EIS stands for electrochemical impedance spectroscopy. An EIS test applies a small alternating signal to a lithium-ion cell and measures its impedance across a range of frequencies. The resulting impedance spectrum shows the internal condition of the cell, so its performance and expected lifetime can be assessed without charging or discharging it.
The operator places the lithium pouch or prismatic cells on a fixture on the tray. The test itself then runs fully automatically. Multiple test profiles can be configured and combined in one sequence on the main HMI screen, and the results are transferred to higher-level systems via CAN bus and Ethernet interface.
Cells with deviating internal properties reduce the performance and lifetime of the whole battery module. EIS testing before assembly classifies each cell and identifies deviations in the incoming cell quality at an early stage. This allows manufacturers to sort out faulty cells and continuously monitor the quality of their cell supply.
The Semiautomatic EIS Test Machine for Lithium Pouch Cells measures up to 32 impedance points simultaneously and predicts battery performance and lifetime in about one second per test. This makes EIS classification fast enough for regular quality control in production, not only for laboratory analysis.
