Claims

6. Electrical energy storage device (2) according to the preceding claim, wherein the electrical connection means (28) protrudes from at least one stud (26) of the support (24) towards the cell (10).

7. Electrical energy storage device (2) according to the preceding claim, wherein the retaining member comprises at least two spring blades (30) arranged angularly to each other at an angle between 120 and 180°.

8. Electrical energy storage device according to any one of claims 5 to 7, wherein a single pad (26) participates in centering at least two cells (10).

9. Electrical storage device (2) according to any one of the preceding claims, comprising a cooling circuit (32), at least a portion of the electrical connection means (34) being heat-treated by the cooling circuit (32).

10. Electrical energy storage device (2) according to the preceding claim, comprising a dielectric fluid which circulates within the cooling circuit (32). [Fig. 1] 30 [Fig. 2] 7 [Fig. 3] 10 28, 30 [Fig. 4] 7 30
