Fixation of a battery module in a battery module compartment of an energy storage system
In an embodiment, an expansion component (e.g., expanding foam element, inflatable pad, a pneumatic or hydraulic mechanism, etc.) is arranged inside of a battery module compartment (e.g., on a bottom interior surface of the battery module compartment). A battery module is inserted into the battery module component and is fixated, or secured, within the battery module compartment at least in part based upon the expanding component which starts to expand or continues to expand after the insertion. In a further embodiment, the battery module may be removed from the battery module compartment after a contraction function (e.g., collapse of the foam element, deflation of the inflatable pad, etc.) of the expansion component is initiated.
1. A battery module fixation arrangement, comprising:
a battery module compartment;
a battery module arranged inside the battery module compartment; and
an expansion component arranged between at least a portion of at least one side of the battery module and an interior surface of the battery module compartment, the expansion component configured to expand after insertion of the battery module into the battery module compartment so as to secure the battery module inside the battery module compartment.
2. The battery module fixation arrangement of claim 1 , wherein the expansion component includes a foam element.
3. The battery module fixation arrangement of claim 2 ,
wherein the foam element is placed in direct contact with the interior surface of the battery module compartment, or
wherein the foam element is arranged inside of a bag.
4. The battery module fixation arrangement of claim 1 , wherein the expansion component includes an inflatable pad.
5. The battery module fixation arrangement of claim 1 , wherein the expansion component includes a pneumatic or hydraulic mechanism.
6. The battery module fixation arrangement of claim 1 , wherein the expansion component is further configured to contract to permit removal of the battery module from the battery module compartment.
7. The battery module fixation arrangement of claim 1 , wherein the at least one side includes an underside of the battery module.
8. The battery module fixation arrangement of claim 1 , wherein the expansion component is arranged on less than all of the at least one side of the battery module.
9. The battery module fixation arrangement of claim 8 , wherein the expansion component is arranged in strips along the at least one side of the battery module.
10. A method of fixing a battery module inside of a battery module compartment, comprising:
arranging an expansion component on an interior surface of the battery module compartment;
inserting the battery module into the battery module compartment,
wherein the expansion component is positioned between at least a portion of at least one side of the battery module and the interior surface of the battery module compartment after the inserting, and
wherein the expansion component is configured to start to expand or continue expanding after the inserting so as to secure the battery module inside the battery module compartment.
11. The method of claim 10 , wherein the expansion component includes a foam element.
12. The method of claim 11 , further comprising:
placing the foam element in the battery module compartment before the inserting,
wherein the foam element starts to expand after the placing and before the inserting, and
wherein the foam element continues to expand before the inserting.
13. The method of claim 12 ,
wherein the placing places the foam element in direct contact with the interior surface of the battery module compartment, or
wherein the foam element is arranged inside of a bag, and the placing places the bag in direct contact with the interior surface of the battery module compartment.
14. The method of claim 10 , wherein the expansion component includes an inflatable pad.
15. The method of claim 14 , further comprising:
placing the inflatable pad in the battery module compartment before the inserting, and
inflating the inflatable pad by filling the inflatable pad with a gas or liquid after the inserting.
16. The method of claim 10 , wherein the expansion component includes a pneumatic or hydraulic mechanism.
17. The method of claim 10 , wherein the expansion component is further configured to contract to permit removal of the battery module from the battery module compartment.
18. The method of claim 10 , wherein the at least one side includes an underside of the battery module.
19. The method of claim 10 , further comprising:
initiating a contraction function of the expansion component while the expansion component is in an expanded state; and
removing, after the expansion component is contracted by the contraction function, the battery module from the battery module compartment.
20. The method of claim 19 , wherein the expansion component includes a bag containing a foam element.
21. The method of claim 20 , wherein the contraction function includes causing the foam element to collapse based on injection of a foam contraction material into the bag.
22. The method of claim 19 , wherein the expansion component includes an inflatable pad.
23. The method of claim 22 , wherein the contraction function includes deflating the inflatable pad.
24. The method of claim 19 , wherein the expansion component includes a pneumatic or hydraulic mechanism.
25. The method of claim 24 , wherein the contraction function includes reducing pneumatic or hydraulic force exerted by the expansion component on the battery module.
26. The method of claim 19 , wherein the at least one side includes an underside of the battery module.
