CROSS REFERENCE
The present invention is an improvement/modification of the invention described and claimed in a complete specification filed on 11* Oct, 2017 for Indian Patent Application No. 201641036961 (IN'961 Application) dated 27th October, 2016 and having incorporated all the disclosure of the IN'961 Application as reference for the present invention.
FIELD OF INVENTION
The present invention generally relates to battery casings and more particularly, to the battery casings with one or more cell spacers.
BACKGROUND OF THE INVENTION
A cell spacer is a partition placed between two cells in order to achieve multiple objectives. The first objective of the cell spacer is to create a cell lock preventing the two cells from moving and touching each other. The second objective of the cell spacer is to prevent a thermally conducting material or any fluid to flow between the two cells. The third objective of the cell spacer is to provide an area for the thermal conducting material to fill in space between the two cells and battery casing.
However, there are plenty of problems associated with the existing cell spacers. The existing cell spacers employ vertically positioned cell bars mounted opposite to each other in the battery casing and this position of the vertically positioned cell bars is considered to be in an original position. In an event, a cell is inserted between the cell spacers positioned opposite to each other; the insertion of the cell causes a permanent deviation of the cell bars from the original position. This may result in a permanent deviation of the cell bars and may cause a physical contact between the two cells, thereby defeating the objective of the cell spacer and causing a short circuit. Additionally, the cell spacers move during the motion

of a vehicle within which the battery casing is mounted. This movement of the cell spacers also results in the permanent deviation of the cell bars from the original position, damage to the cell spacers as well as the cells inserted on the cell spacers.
Therefore, there is a need to build a cell spacer which restores/returns the cell bars to the original position on the insertion of the cell between the cell bars. Further, there is a need to build a cell spacer which reduces the permanent deviation of the cell bars from the original position. Furthermore, there is also a need to build a cell spacer creating a permanent barrier between the two cells avoiding any physical contact between two placed adjacent to each other.

DETAILED DESCRIPTION OF THE INVENTION
In the following description, for the purposes of explanation, various specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that the disclosed embodiments may be practiced without these specific details. Several features described hereafter can each be used independently of one another or with any combination of other features. Also, the well-known structures and devices are shown in line diagram form in order to avoid unnecessarily obscuring the present invention.
The present invention relates to a cell spacer with an additional physical member for avoiding any physical contact between at least two cells inside a casing.
As illustrated in Fig. 1A and Fig. IB, the present invention relates to a cell spacer [100] comprises a lateral member [102], a first cell bar [104A], a second cell bar [104B], at least one first cell seat [106] and an elastic member [108].
The lateral member [102] encompasses a first end and a second end, and is extended along a first plane in a first axis. The lateral member [102] has one of at least one first cell seat [106] and a second cell seat.

In an embodiment, the lateral member [102] has at the least one first cell seat [106] and the at least one first cell seat [106] protruding from at least one of the first end and the second end to accommodate at least one cell. Further, the at least one first cell seat [106] is protrudes along the first plane in a second axis perpendicular to the first axis. In an embodiment, a first cell seat protrudes from the first end and a second cell seat protrudes from the second end to accommodate the at least one cell.
In another embodiment, the lateral member [102] has the second cell seat and the second cell seat protruding along a length of the first end and the second end to accommodate the at least one cell. Further, the second cell seat is configured along the first plane in the second axis perpendicular to the first axis. The protrusion of the second cell seat along a length the first end and the second end creates a long slab for accommodating the at least one cell.
The invention also encompasses a first cell bar [104A] and a second cell bar [104B] configured at the first end and the second end of the lateral bar [102] respectively. Further, the first cell bar [104A] and the second cell bar [104B] are extended in a third axis perpendicular to the first axis and the second axis. The first cell bar [104A] and the second cell bar [104B] prevents the physical contact between the at least two cells. Furthermore, the first cell bar [104A] and the second cell bar [104B] also supports the at least two cells accommodated on one of the at least one first cell seat [106] and the second cell seat.
The lateral member [102] also has at least one cell spacer stand [110] extended opposite to one of the first cell bar [104A] and the second cell bar [104B] in the third axis. Further, the at least one cell spacer stand [110] creates a gap between the casing and the lateral member [102]. The gap created between the casing and the lateral member [102] may be filled by thermal conducting material such

as epoxy and silicon. The lateral member [102] also encompasses a locking mechanism to lock the cell spacer [100] to the casing.
The present invention also encompasses an elastic member [108] configured to interconnect an inner side the first cell bar [104A] with an inner side of the second cell bar [104A]. The elastic member [108] is made of a rubber material, a plastic material and any other elastic material known in the art. Further, the elastic member [108] also act as a physical barrier between the at least two cells. In another embodiment, a first cell spacer connected to a second cell spacer is mounted inside the casing and a cell is inserted and accommodated by the first cell spacer and the second cell spacer. Similarly, a plurality of said cell spacers are mounted on the casing and one cell each is accommodated between two adjacent cell spacers. The first cell spacer has a first elastic member whereas the second cell spacer has a second elastic member. The first elastic member and the second elastic member maintains cell bars of both the first cell spacer and the second cell spacer in respective original position even on insertion of the cell between the first cell spacer and the second cell spacer due to elastic property. Thereby, the elastic members restore/return the cell bars to the original position on insertion of the cell between the cell spacers. Therefore, the elastic members also eliminate the problem of permanent deviation of the cell bars on insertion of the cell between the cell spacers.
In another embodiment as shown in FIG. 1C, the cell spacer [100] is configured with at least one protrusion [112] to lock the cell spacer [100] within the casing. The at least one protrusion [112] is configured in an outward direction from an outer side of the first cell bar [104A] and an outer side of the second cell bar [104B]. The locking of the cell spacer [100] prevents any movement of the first cell bar [104A] and the second cell bar [104B], thereby eliminating the problem of deviation of the cell bars [104A, 104B] on insertion of the cell between the cell

spacers. The at least one protrusion [112] is configured to only allow a vertical movement of the cell spacer [100] within the casing, thereby locking the cell spacer [100] within the casing. Further, the at least one protrusion [112] may be of uniform or variable dimensions for a proper locking of the cell spacer [100] within the casing.
Although, the present invention has been described in considerable detail with reference to certain preferred embodiments and examples thereof, other embodiments and equivalents are possible. Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with functional and procedural details, the invention is illustrative only, and changes may be made in detail, especially in terms of the procedural steps within the principles of the invention to the full extent indicated by the broad general meaning of the terms. Thus, various modifications are possible of the presently disclosed system and process without deviating from the intended scope and spirit of the present invention. Accordingly, in one embodiment, such modifications of the presently disclosed system are included in the scope of the present invention.
