The present disclosure relates to a battery module, including: 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), 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); 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). The battery module provided in the disclosure meets the requirements of power supply, and meanwhile the safety performance of each battery cell (21) under the overcharge condition of the battery module can be ensured.
