摘要
A battery cover plate assembly (103), a cell (100), a battery module (300), a power battery (400) and an electric vehicle (500). The battery cover plate assembly (103) includes a cover plate (1), a first pole (2), a second pole (103a), a flipping member (5), a scored member (6), a first conductive member (7) and a telescopic assembly (103b). The second pole (103a) includes an upper pole (3) and a lower pole (4) spaced apart from each other. The flipping member (5) is configured to turn over under the action of gas pressure inside the battery and push, by means of the telescopic assembly (103b), the first conductive member (7) to move to break a score (62), so as to electrically disconnect the upper pole (3) from the lower pole (4).
