A battery cover plate assembly, a cell, a battery module, a power battery and an electric vehicle are provided. The battery cover plate assembly includes a cover plate, a first pole, a second pole, a flipping member, a scored member, a first conductive member and a telescopic assembly. The second pole includes an upper pole and a lower pole spaced apart from each other. The flipping member is configured to turn over under the action of gas pressure inside the battery and push, by means of the telescopic assembly, the first conductive member to move to break a score, so as to electrically disconnect the upper pole from the lower pole.
