The battery module (4) is internally provided with a pressure relief cavity (43) and at least one cell (41). The pressure relief assembly includes a guide pipe (1) and an explosion-proof valve (2). The guide pipe includes provided with a plurality of flow-collecting sections (11) and at least one converging section (12). The plurality of flow-collecting sections are respectively in communication with the pressure relief cavities of the plurality of battery modules. The flow-collecting section is provided with a first port and a second port. The first port is in communication with the pressure relief cavity of a corresponding battery module, and the second port is in communication with the flow-converging section. One end of the explosion-proof valve is in communication with the flow-converging section, and the other end is in communication with an exterior of the power battery system. A gap is reserved between both the flow-collecting section and the flow-collecting section and the cells in the power battery system.
