Brought to you by the IEEE Consultants Network of Long Island (LICN)

Accurately measuring lithium-ion battery performance is more challenging—and more critical—than it first appears. Small measurement errors can lead to incorrect conclusions about state of charge, health, and long-term reliability.

This presentation takes a practical, engineering-focused look at how key battery parameters are measured, what they really tell you, and where common methods fall short.

Topics include:

  • Open Circuit Voltage (OCV) and its real-world limitations
  • Self-discharge: what it reveals about cell quality
  • ACIR vs DCIR: lab measurements vs real operating conditions
  • Electrochemical Impedance Spectroscopy (EIS) fundamentals
  • Capacity measurement and dominant sources of error
  • The impact of temperature, relaxation effects, and instrumentation accuracy

We will also explore:

  • Why traditional measurement techniques can be misleading
  • Faster and more effective methods for identifying weak or abnormal cells
  • Practical insights you can apply immediately in design, testing, and evaluation

Whether you're working in product design, manufacturing, or testing, this session will help you better understand what your battery measurements are really telling you—and what they’re not.
