- the protective devices of the network were then sized to be able to cut short circuit currents for example of this type of battery, these currents can for example be up to 50 kA.
- the Applicant has already proposed reducing the short-circuit current in the event of an internal or external fault by inserting into the power line of each branch in parallel constituting the electrical energy storage system, for example a current chopper.
- This chopper then makes it possible to limit the output current of each branch to a value parameterized in advance.

- This system requires a discharge circuit and a load circuit decoupled for example by diodes.
- This system proposes to insert, in the event of a fault on the network, a resistance in the power line of the branches of the battery to attenuate the value of the current by dissipating a high heat energy.
- a system of static switches for example semiconductor deflects the current in this resistance in case of overcurrent detected at the output of the branches of the battery.
- This system requires a water cooling device and requires a complete study of the protection and selectivity plan of the electrical network of each type of submarine where it is installed, in order to define the value of the resistance that will allow limit the short-circuit current to a value allowing the operation of the electrical protection systems of the network.

- network connection means means for generating a controlled short-circuit current, for triggering the operation of the cutoff and isolation means associated with the short-circuited branch, in order to isolate it from the rest of the network,
- the means for monitoring the evolution of the current delivered by the electrical energy storage means comprise means for analyzing the variation of this current over time in order to detect the appearance of a short circuit as soon as this variation exceeds a predetermined threshold;
- the electrical energy storage means comprise a plurality of branches in parallel, each of which comprises disconnection means;

- FIG. 1 represents the general structure of part of a system for supplying electrical energy, in particular an onboard network of a submarine;
- FIGS. 2 to 7 illustrate the operation of such a system; according to a first embodiment, and
- This comprises means for storing electrical energy based on lithium batteries, designated by the general reference 1.
- these energy storage means comprise several battery branches in parallel, designated by the general references 2, 3 and 4, for example in this FIG.
- Each of these branches is connected to a battery panel designated by the general reference 5, through connection / disconnection means, respectively 6, 7 and 8.
- connection / disconnection means comprise, for example, semiconductor switching devices.
- controlled conductors such as for example MOSFET transistors, inserted in the branches.
- the battery table 5 also comprises a circuit breaker designated by the general reference 9.
- This battery board 5 is connected to at least one main electric power distribution board, one of which is designated for example by the general reference 10 in this FIG.
- This main electrical power distribution panel 10 also comprises for example several power supply branches, each of which also comprises a circuit breaker.
- This power supply branch makes it possible to connect this main electrical energy distribution board 10 to at least one secondary electric power distribution board, one of which is designated for example by the general reference 12 in this figure.
- This secondary electric power distribution board 12 supplies user load connection branches, for example the branch designated by the general reference 13 in this figure, through branch breaking and isolation means, comprising: also for example a circuit breaker, designated by the general reference 14.

- Each of these tables comprises means of cut-off and isolation for example based circuit breakers, which are then calibrated according to their location in the power supply, to cut the corresponding branch and isolate it from the rest of the network.
- Cutting means comprising semiconductor devices are used for this purpose.
- the short circuit current of the system can reach extremely important values.
- a DC fuse according to current technologies has a breaking capacity of only 100 kA maximum and must be changed after melting, which, in the applications mentioned, is not conceivable or at least not is not acceptable, for reasons of accessibility and rapid availability of energy after a fault.
- a DC circuit breaker which can be reset, also has a breaking capacity of the order of 100 kA maximum according to current technologies.
- Another aspect to take into account when dimensioning the protection of such a circuit, and in particular the calibration of the circuit breakers, is the selectivity of the different elements of the whole chain or the cascade of circuit breakers or fuses of the electrical distribution of the system.

- the system opens the means 16 for connecting the short-circuit generator to disconnect it from the network.
- the system causes the disconnection of the battery at first. Then the short circuit generation means are connected to the network to cause the tripping of the protection circuit breaker of the faulty user load branch.
