ABSTRACT:
A battery assembly (E) comprises firstly a battery (B) having at least one module (1-i) constituted by at least two secondary electrochemical cells (2-j) connected in series, and secondly control apparatus comprising control means (4) for acting at the end of charging the battery (B) to determine the number of cells (1-i) that are in working condition in each module (2-j) and then for determining a threshold voltage value for each module (1-i) as a function of said number, and finally for acting at the end of discharge of the battery (B) to compare an end-of-discharge voltage measured across the terminals of each module (1-i) with the corresponding threshold voltage as previously determined so as to interrupt operation of the battery (B) when at least one measured end-of-discharge voltage (VFD-i) is less than the corresponding value determined for the threshold voltage.
