A battery architecture based on putting n branches of battery modules in parallel associated with a DC/DC converter, the whole being controlled by an intelligent controller. It is thus possible to isolate a branch, connect it to the DC/DC converter and then carry out operations of charging or discharging of this branch using the power available from the battery modules of the n−1 other brandies. At the same time the n−1 other branches remain available for a user. The branch that has been isolated is then reconnected to the other branches to reconstitute the initial system. This architecture makes it possible to carry out operations such as balancing of voltages between modules, determination of the state of charge, and measurement of capacity. This architecture comprises a single voltage step-down/step-up DC/DC converter, bidirectional with respect to current, able to provide, in each branch individually, the charging and discharging of the module or modules of said branch.
