Abstract
A method detects defects in an electrical power storage system including at least one battery. The method includes applying an instruction for charging or discharging the battery. The method also includes measuring the current passing through the battery during application of the instruction and calculating m×n mean errors (eTj(tij))1≤j≤m, 1≤i≤n between the measured current and the theoretical current of the instruction in m×n time intervals ([tij, tij+Tj])1≤j≤m, 1≤i≤n, respectively. The method also includes calculating, for each j between 1 and m, ej=max(eTj (tij)), where i=1, . . . , n. Lastly, the method includes incrementing a counter Cj if ej completely or partially exceeds a predetermined threshold. A defect is detected if Cj exceeds a predetermined threshold.
