Ensure EV Battery Cell and Module Safety and Performance

Manufacturing of safe, reliable, and top-performing electric vehicle (EV) batteries demands rigorous testing of the hundreds of battery cells and modules. With the growing consumer demand for EVs, battery manufacturers and OEMs are pressured to accelerate production—without sacrificing precision, repeatability, and traceability. To minimize the risk of failure and damaging recalls, EV test engineers need to:

 

  • Perform different tests like weld integrity, open-circuit voltage (OCV), and AC internal resistance (AC-IR) during assembly and finishing of battery cells and modules
  • Shorten test times to meet production volume with zero compromises on test precision and quality
  • Precisely control test probes at high speed to make measurements on test cells and modules 
  • Make extremely precise measurements at high speed for high channel counts and long test runs
  • Use their test data to drive insights that help them continuously improve the test process

EV Battery Cell and Module Production Test Solution

  •  PXI provides the most compact and high-performance form factor to pack more test and scale up production volumes.
  • The source measurement unit (SMU) provides repeatable and precise measurement and current sourcing for AC-IR and weld integrity test.
  • The digital multimeter (DMM) performs fast and precise voltage measurements for OCV and weld integrity test.
  • 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.
  • Direct integration with production test software like TestStand, Switch Executive, and SystemLink™ for enterprise data and systems management.
