摘要

A battery module includes: one or more cell assemblies; a main housing comprising a main boundary portion surrounding an accommodation space in which the one or more cell assemblies are positioned; a first plate comprising a first boundary portion coupled with the main boundary portion and a first exposure portion exposed from the main boundary portion and defining a side of a cooling fluid passage for cooling the accommodation space; and a second plate facing the first plate and comprising a second boundary portion coupled with the main boundary portion and a second exposure portion exposed from the main boundary portion and defining an other side of the cooling fluid passage.

說明書

Referring to FIG. 8, the second coupling line L2 may include the coupling between the main inner boundary portion MI and the second boundary portion P2a of the second plate P2. The sealing portion 50 may be arranged between the main inner boundary portion MI and the second boundary portion P2a to mediate the coupling between the main inner boundary portion MI and the second boundary portion P2a. The sealing portion 50 may form the coupling with the second boundary portion P2a formed around the slit S of the second plate P2 and may be formed to have a symmetrical shape so as to be coupled with the second boundary portion P2a formed at both sides of the slit S.

According to some embodiments, the sealing portion 50 may include a third sealing portion 53 extending between the second boundary portion P2a and the main inner boundary portion MI and a fourth sealing portion 54 extending from the slit S of the second plate P2 in a direction crossing the third sealing portion 53. For example, the third sealing portion 53 may extend in the surface direction (the second direction Z2) of the second plate P2, and the fourth sealing portion 54 may extend in the direction crossing the third sealing portion 53, for example, the thickness direction (the third direction Z3) of the second plate P2.
