Abstract

Abstract

En 中文
• Robustness analysis of battery pack diagnostics for EVs. • External influences on EV state of health determination and differential voltage analysis. • Variations in charging power, temperature, current direction and resting SOC. • Reproducibility and comparability of the measurement procedure with identical EVs. • Derivation of recommendations for the measurement procedure.
