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, an inner lead-out member, and an outer electrode terminal. The inner lead-out member and the outer electrode terminal are electrically connected by using a current interrupt apparatus. A flipping member of the current interrupt apparatus is electrically connected to the outer electrode terminal. A score member is electrically connected to the inner lead-out member. A score is formed on the score member and is electrically connected to the flipping member. The inner lead-out member is mounted on the cover plate through a cover plate insulator. The cover plate insulator has a first engagement portion engaged with the cover plate and a second engagement portion engaged with the inner lead-out member.

Battery cover plate assembly comprising a current interrupt apparatus

A battery, a battery pack, and a vehicle are disclosed. The battery includes a housing having a sealed chamber, a core packaged in the sealed chamber, and a first terminal and a second terminal respectively mounted to the housing, where the first terminal is electrically connected to the housing, and the second terminal is insulated from the housing. The battery further includes a first tab and a second tab respectively led out from the core, the first tab being electrically connected to the housing, the first tab being electrically connected to the first terminal through the housing, and the second tab being electrically connected to the second terminal.

Battery, battery pack, and vehicle

A battery cover plate assembly includes a cover plate, an electrode terminal, a current interrupt structure, and an arc extinguishing portion. The electrode terminal is disposed on the cover plate and includes an electrode inner terminal and an electrode outer terminal. The electrode inner terminal and the electrode outer terminal are electrically connected through the current interrupt structure. The current interrupt structure is capable of disrupting the electrical connection between the electrode inner terminal and the electrode outer terminal under the action of a gas pressure. The arc extinguishing portion is configured to reduce an electric arc generated when the current interrupt structure disrupts the electrical connection between the electrode inner terminal and the electrode outer terminal. When the electrical connection between the electrode inner terminal and the electrode outer terminal is disrupted, an arcing effect is generated due to high voltages at positive and negative electrodes of the battery.

Battery cover plate assembly, single cell battery, battery module, power battery pack, and electric car

A battery spacer, an electric core protection assembly having the battery spacer and a power battery are provided. The battery spacer includes: a spacer body; a plurality of protrusions, each protrusion protruding from an inner surface of the spacer body, extending in a longitudinal direction of the spacer body, and formed by recessing a portion of an outer surface of the spacer body; a plurality of grooves formed in the outer surface of the spacer body, each groove corresponding to one of the plurality of protrusions respectively and formed by recessing the portion of the outer surface of the spacer body; and a plurality of liquid guiding slots formed in the outer surface of the spacer body and extending from the grooves to an edge of the spacer body respectively.

Battery spacer, electric core protection assembly and power battery

A sealing member and a battery comprising the sealing member are provided. The sealing member comprises a sealing part, an operation part having a supporting portion, an operation protrusion disposed on an upper surface of the supporting portion, and a deformable leg depending from a bottom surface of the supporting portion. The sealing member also comprises a connecting part connecting the sealing part and operation part. The sealing part has a maximum diameter greater than that of the connecting part.
