The management of an electrical energy storage battery requires the provision of a non-dissipative balancing device for balancing the electric voltages at the terminals of the storage elements of the battery, comprising N+1 switching elements of a first type (Cpk) capable of electrically connecting, in parallel, two storage elements belonging respectively to first and second branches to a same stage and 2N switching elements of a second type (Cdk,1, Cdk,2) capable of electrically connecting, in parallel, two storage elements belonging respectively to the first and second branches to adjacent stages. It involves making a selection that consists of choosing only a portion of the storage elements of the first branch corresponding to a lower number of stages than the total number of stages of the battery and only a portion of the storage elements of the second branch corresponding to a lower number of stages than the total number of stages of the battery. The switching elements are controlled by electrically connecting the storage elements selected from the first branch and the storage elements selected from the second branch to each other, in parallel. |
