New research analyzing real-world electric vehicle battery performance has uncovered a critical factor in their declining efficiency: uneven aging among individual cells. While manufacturers often assume all cells degrade at similar rates, field data shows significant discrepancies, with some cells degrading far faster than others. This inconsistency accelerates overall battery degradation, potentially reducing lifespan and performance. The findings challenge conventional battery management approaches and could reshape how EV manufacturers design and maintain battery systems.
