The invention provides a battery. The battery comprises a shell, a plurality of accommodating cavities, a partition plate, a pole core group, a liquid guide hole and a blocking mechanism, wherein the liquid guide hole is used for communicating the accommodating cavities on two sides of the partition plate; the blocking mechanism is at least partially arranged in the partition plate and can rotate relative to the partition plate; the blocking mechanism divides the liquid guide hole into a first liquid guide hole and a second liquid guide hole, and a through hole is formed in the blocking mechanism; when the blocking mechanism is in a first state, the first liquid guide hole and the second liquid guide hole communicated through the through hole so as to communicate two adjacent containing cavities on the two sides of the partition plate; when the blocking mechanism is in a second state, the first liquid guide hole and the second liquid guide hole are separated by the blocking mechanism, so that the two adjacent containing cavities on the two sides of the partition plate are disconnected; the blocking mechanism can rotate from the first state to the second state. The invention also provides a battery module, a battery pack and an electric vehicle based on the invention. Communication and closing between the two adjacent containing cavities on the two sides of the partition plate are achieved through the blocking mechanism in a rotating mode.
本发明提供了一种电池,包括壳体、多个容纳腔、隔板、极芯组、导液孔和阻挡机构;导液孔用于连通隔板两侧的容纳腔;阻挡机构至少部分设置在隔板中,且可相对隔板旋转;阻挡机构将导液孔分隔成第一导液孔和第二导液孔,阻挡机构上设置有导通孔;阻挡机构位于第一状态时,第一导液孔和第二导液孔通过导通孔连通,以连通隔板两侧相邻的两个容纳腔;阻挡机构位于第二状态时,阻挡机构隔开第一导液孔和第二导液孔,以断开隔板两侧相邻的两个容纳腔之间的连通;阻挡机构可由第一状态旋转至第二状态。本发明还提供了基于本发明提供电池模组、电池包和电动车。本发明通过阻挡机构以旋转的方式来实现隔板两侧相邻的两个容纳腔之间的连通和关闭。
