1. Cell charging

1.2. Battery aging

  • The aging of the battery results in a gradual reduction in capacity.
  • Symptoms:
    • capacity reduction,
    • internal resistance increase,
    • shortening of the 1st charging step (= constant current charging),
    • extension of the saturation part (= constant voltage charging).
