2. The energy storage system as claimed in claim 1 ,

wherein exactly one active vent valve is arranged on the cover element of the housing such that the active vent valve is assigned to a chamber that is arranged in a central region of the interior of the housing.

3. The energy storage system as claimed in claim 1 ,

wherein two active vent valves are arranged on the cover element of the housing such that the two active vent valves are assigned to two chambers that are separated from one another via at least one chamber that is assigned a blind plug.

4. The energy storage system as claimed in claim 1 ,

wherein each dividing wall has at least one opening for forming the fluidic connection between the individual chambers.

5. The energy storage system as claimed in claim 4 ,

wherein at least one of the multiplicity of dividing walls has in each case exactly one opening in an upper region of the corresponding dividing wall.

6. The energy storage system as claimed in claim 5 ,

wherein the one opening per dividing wall is arranged such that at least two adjacent dividing walls have the opening in an offset manner.

7. The energy storage system as claimed in claim 5 ,

wherein at least one dividing wall has the one opening in an upper, central region of the corresponding dividing wall.

8. The energy storage system as claimed in claim 4 ,

wherein at least one of the multiplicity of dividing walls has in each case exactly two openings in an upper region of the particular dividing wall.

9. The energy storage system as claimed in claim 2 ,

wherein a membrane is formed in at least one of the openings.

10. The energy storage system as claimed in claim 1 ,

wherein the active vent valve is in the form of a one-way valve with a predetermined or predeterminable venting pressure.

11. The energy storage system as claimed in claim 1 ,

wherein the blind plugs are in the form of vent plugs, which are configured to seal off the interior of the housing.

12. The energy storage system as claimed in claim 1 ,

wherein the energy storage system is in the form of a valve-regulated lead-acid battery.

13. The energy storage system as claimed in claim 5 ,

wherein all of the dividing walls have in each case exactly one opening in an upper region of the corresponding dividing wall.

14. The energy storage system as claimed in claim 6 ,

wherein the one opening per dividing wall is arranged such that at least two adjacent dividing walls have the opening in an alternately offset manner.

15. The energy storage system as claimed in claim 14 ,

wherein the one opening per dividing wall is arranged such that at least two adjacent dividing walls have the opening in the alternating offset manner in the two upper end regions of the dividing walls.

16. The energy storage system as claimed in claim 7 ,

wherein all of the dividing walls have the one opening in an upper, central region of the corresponding dividing wall.

17. The energy storage system as claimed in claim 8 ,

wherein all of the dividing walls have in each case exactly two openings in an upper region of the corresponding dividing wall.

18. The energy storage system as claimed in claim 17 ,

wherein the two openings are arranged in each case in two upper end regions of the corresponding dividing wall.

19. The energy storage system as claimed in claim 10 ,

wherein the one-way valve is integrated into a vent plug.

20. A lead-acid battery comprising:

a multiplicity of energy storage cells of the lead-acid type to provide and store electrical energy;

a housing comprising:

a multiplicity of wall elements and a cover element, all of which bound an interior of the housing, accommodating the multiplicity of energy storage cells in the interior of the housing; and

a multiplicity of dividing walls to subdivide the interior of the housing into a multiplicity of chambers arranged in the interior of the housing, each chamber accommodating a respective one of the multiplicity of energy storage cells, and each dividing wall defining a respective fluidic connection between adjacent chambers of the each dividing wall; and

a multiplicity of vent valves arranged on and extending through the cover element of the housing, each vent valve of the multiplicity vent valves corresponding to a respective chamber of the multiplicity of chambers, in each case in a region assigned to the respective chamber, wherein

at least one of the vent valves is an active vent valve and the rest of the vent valves are blind plugs, and
