BATTERY MODULE
FIG5 is a schematic structural diagram of a first end plate shown in FIG2  FIG6 is a schematic structural diagram of a blocking member shown in FIG2
Referring to FIG5, it shows a schematic structural diagram of the first end plate 30 in FIG2. Each of the first end plate 30 and the second end plate 40 includes a body portion 33 in a plate-like form and connection portions 34 positioned at both ends of the body portion 33 and connected to the body portion 33 in the second direction Y. The battery module can be connected to an outside part (e.g. a bottom of a battery box) via the connection portions 34. The main body portions 33 of the first end plate 30 and the second end plate 40 are respectively disposed in the two openings 11 of the housing 10 and connected to the housing 10. The connection is preferably a sealed connection, such as a welding connection, a bonding connection, or the like.  Referring to FIG6, it shows a schematic structural diagram of the blocking member 50 in FIG2. In an optional embodiment, the blocking member 50 includes an abutment portion 51 and an adapter portion 52 connected to each other. The abutment portion 51 is disposed opposite to the second vent plate 212 of each battery cell 21, and the adapter portion 52 is connected with the second end plate 40. The blocking member 50 with the above structure is easy to process and has a low cost.

['1. A battery module,  characterized by  comprising: a housing (10) having two oppositely disposed openings (11) and a hollow chamber communicating with the two openings (11) in a first direction (X); a battery stack (20) disposed in the hollow chamber and comprising two or more battery cells (21) stacked in a second direction (Y) and electrically connected to each other, wherein each of the two or more battery cells (21) has a first vent plate (211) and a second vent plate (212) disposed opposite to each other in the first direction (X); a first end plate (30) corresponding to one of the two openings (11) and connected to the housing (10), wherein the first end plate (30) is provided with a module output pole (31) electrically connected to the battery stack (20) and a deformable plate (32) disposed opposite to the module output pole (31), and the deformable plate (32) faces the first vent plate (211) such that the deformable plate (32) deforms and is electrically connected to the module output pole (31) when the first vent plate (211) is opened; a second end plate (40) corresponding to the other of the two openings (11) and connected to the housing (10); and a blocking member (50) disposed between the second end plate (40) and the battery stack (20) such that a pressure for opening the second vent plate (212) is greater than a pressure for opening the first vent plate (211).', '2. The battery module of claim 1, wherein the blocking member (50) comprises an abutment portion (51) and an adapter portion (52) connected to each other; the abutment portion (51) is disposed opposite to the second vent plate (212) of each of the two or more battery cells (21); and the adapter portion (52) is connected with the second end plate (40).', '3. The battery module of claim 2, wherein the abutment portion (51) comprises a plate-like structure extending in the second direction (Y); the plate-like structure has a first surface (511) and a second surface (512) disposed opposite to each other in a thickness direction of the plate-like structure; the first surface (511) faces the second end plate (40); the  second surface (512) faces the second vent plate (212); and the first direction (X) is perpendicular to the second direction (Y).', '6. The battery module of claim 3, wherein the plate-like structure is provided with an open notch (513) that penetrates the plate-like structure in the thickness direction.']
