Abstract
A process of managing an electrochemical battery (10) comprising measuring at least one first internal resistance (R<sub>HF</sub>(t)) of the battery at at least a first frequency (f<sub>1</sub>) and comparing the measured first internal resistance (R<sub>HF</sub>(t)) with a first reference internal resistance (R<sub>HF</sub>,<sub>REF</sub>); if the first measured internal resistance is less than or equal to the first reference internal resistance, making a decision regarding continued use of the battery; and otherwise measuring at least one second internal resistance (R<sub>LF</sub>(t)) of the battery at least one second frequency (f<sub>2</sub>) lower than the first frequency and comparing a difference D(t) between the measured second and first internal resistances with a reference difference (D<sub>REF</sub>) between a second and the first reference internal resistances (R<sub>LF</sub>,<sub>REF,</sub> R<sub>HF</sub>,<sub>REF</sub>); and if the difference D(t) is greater than or equal to the reference difference, making a decision regarding a disqualification of the battery (10); and otherwise reducing an intensity of a fast charge and/or regeneration current for a subsequent charging step.
