BatteryFlex™

A FASTER, more EFFICIENT, and FLEXIBLE way to test device batteries.

BatteryFlex is a platform for evaluation and characterization of a wide range of battery cells and battery packs used in medical devices and small electronics. 


BatteryFlex relies on instrumentation in a PXI chassis platform, which allows for the addition of unlimited input or output signals, controls, or measurements. Combined with user-made sequence scripts and playback of real-world simulated load scenarios, the capabilities of BatteryFlex are defined by you.

  • Evaluate and analyze battery performance

  • Compare fitness for use of different batteries

  • Generate or verify battery datasheet contents

  • Playback charge/discharge/usage scenarios

  • Long-Term or Accelerated Life Test

  • Automated Stress Screening and Quality Test

  • Extended Measurements (Optical, Temperature, etc.)

  • Any other application defined by User Script
