Evaluate Battery Cell Quality for Electronic and Medical Devices

The market for personal, patient, and IoT devices is growing. It’s crucial to maintain a cell quality test strategy that not only fits the high-volume manufacturing environment but also ensures longevity and accuracy for these devices. Increasing complexities from regulation and added functionality increase the burden for clean test fixtures that provide easily processible data. To meet the high standards of electronics and patient devices, battery cell quality test must:

 

  • Perform different tests like open-circuit voltage (OCV), AC internal resistance and impedance (AC-IR/EIS), leakage, and capacity
  • Shorten test times to meet production volume without compromising compliance and end quality
  • Make precise measurements that can minimize subsequent battery degradation and substandard operating conditions
  • Monitor test data continuously to drive analysis and insight that improves output and efficiency

Electronic and Medical Device Battery Cell Quality Test Solution

  • PXI provides a small form factor and comprehensive I/O that allows for quick and highly accurate test.
  • The source measurement unit (SMU) provides repeatable and precise measurement and current sourcing for AC-IR/EIS, capacity, and leakage tests.
  • The digital multimeter (DMM) performs fast and precise voltage measurements for OCV test.
  • The LCR meter can provide testing for higher frequency needs, up to 2 MHz.
  • NI’s multiplexers effectively scale the system to 32 or 64 channels depending on the type of test, for maximum coverage in a smaller footprint.
  • Production test software—like NI TestStand, NI SystemLink™ software for systems management, and NI InstrumentStudio™ software for extended monitoring and debugging capabilities—provides quick integration with NI PXI hardware.

Solution Advantages

  • Cost-effective, precise, and high-throughput PXI configurations allow for a wide range of measurement and flexibility.

  • NI software helps you execute tests and gather insights to improve uptime, monitor test assets, and perform analysis to continuously enhance quality.

  • NI's compact hardware provides higher channel counts in a smaller form factor.

  • Interactive channel management and intuitive sequence interfaces shorten time to first measurement.

  • NI services provide assistance in development of test architecture and software adoption.
