Implication

Analysis quantifies measurement uncertainty effects on battery parameters, highlighting implications for modeling.

Key Points

  • The study aims to quantify how measurement uncertainty affects key battery parameters in lithium-ion cells.
  • Comprehensive uncertainty analysis of 18650 lithium-ion cells with various cathodes.
  • Application of the law of error propagation to assess uncertainty in measurements.
  • Focus on voltage, current, and temperature measurements and their impact on derived parameters.
  • Small variations in measurements lead to significant deviations in internal resistance and state of charge.
  • Measurement uncertainty varies based on battery chemistry due to different voltage profiles.
  • Findings indicate a notable risk for battery management systems that depend on these parameters.
