Through, another in the embodiment according to the protrusions of the present invention sensing terminal (350 ') is formed on the point bonding from receiving, sensing terminal (350') fill and force can be improved.

[114]

On the other hand, 11 and also of Figure 12 in the embodiment according to said first lateral surface (351 ') is, projections on the inner surface (113') corresponding to the left-right direction width (W3) plurality of 180° in the circumferential (351 'a) is formed projection (113') by pressing, sensing terminal (350 ') surface of one (113') can be between the back plate and fixing force.

[115]

This also 11 and of Figure 12 in the embodiment according to other sensing terminal (350 ') also, first lateral surface (351') extending from both sides of the projection (113 ') while surrounding pressing the terminal portion (353') can be further comprises.

[116]

Pressing terminal portion (353 ') includes a contact terminal part (351') extending from two opposite sides of a projection (113 ') encircling the side of pressing for pressing each terminal number 1 (353'a) and pressing terminal number 2 (353' b) can be a.

[117]

In the embodiment according to number 1 other pressing terminal portion (353 'a) and pressing terminal number 2 (353' b) includes a projection (113 ') mounted to the distal end protrusion (113') corresponding to the left-right direction width (W3) can be in the form of extending.

[118]

I.e., in the embodiment according to number 1 such pressing terminal portion (353 'a) and pressing terminal number 2 (353' b) is longer and wider width protrusions are each whose scope (113 ') installed to the terminal portions of which are adapted to cooperate with the first and a second (113') polishing direction near the center of projection (113') can be pressing. In this case, pressing terminal number 1 (353 'a) and pressing terminal number 2 (353' b) is, first lateral surface (351 ') on either side of the bent protrusion in each cleaning unit consisting of bending and the shape of the curve (113') near the center of direction, i.e. inwardly extending flat having a drain can be configured in the form.

[119]

Through, sensing terminal (351 ') surface of one (113') is combined by facing each other present a large area contact electrically connected, as well as physical stability of binding can be to enhance stability of the electrical connection.

[120]

On the other hand, the present invention according to a battery pack can include, above the battery module comprising one or more. The, battery pack is in addition to the battery module, the battery module for receiving case, battery module of the certain interval symmetrically number for various device, such as BMS (Battery Management System), current sensor, or the like can be further comprises a fuse. In particular, in the embodiment according to one of the present invention battery pack can include, battery module of sensing sensing terminal connecting terminal test seated can be layer is electrically connect to the BMS.

[121]

The present invention according to the battery module has a, electric vehicle or hybrid such as an automotive vehicle can be option value. I.e., the present invention according to the motor vehicle, the present invention according to battery module can be.

[122]

The present invention refers to the aforementioned, the present invention is in the field of the present invention is provided within a range that the technical idea from a heavy person with skill in the art to various substituted, deformation and capable of changing the aforementioned in the embodiment and the attached drawing defined by no robbery.
