The invention relates to the field of energy storage devices, in particular to a power battery top cover structure. The power battery top cover structure comprises a top cover piece, two electrode assemblies and two short circuit parts. At least one of the two electrode assemblies and the top cover piece are arranged in an insulated mode. At least one of the two short circuit parts is fixed to the electrode assemblies. When internal pressure of a power battery exceeds reference pressure, the two short circuit parts both can act under the pressure effect, and each electrode assembly can be electrically connected with the top cover piece through one short circuit part. According to the power battery top cover structure, it can be avoided that the sensitivity of short circuit parts is reduced and the service life of the short circuit parts is shortened due to the fact that the short circuit parts suffer from stress of a top cover piece. 本申请涉及储能器件领域，尤其涉及种动力电池顶盖结构，包括顶盖片、两个电极组件以及两个短路部件，两个所述电极组件中的至少个与所述顶盖片绝缘设置，两个所述短
