Abstract
A current interrupt apparatus and a flipping member thereof, a battery cover plate assembly, a cell, a battery module, a power battery, and an electric vehicle are provided. The flipping member is to be electrically connected to a score member, and can act under an effect of air pressure to break a score on the score member so as to cut off the electrical connection to the score member. A first connection region to be electrically connected to the score member and a second connection region to be electrically connected to an outer electrode terminal of a battery are formed on the flipping member. A deformation cushion region is further formed on the flipping member. The deformation cushion region is disposed between the first connection region and the second connection region and around the first connection region.
