The present application provides a battery unit, a battery module, and a vehicle. The battery unit includes a housing, a cover plate, a first battery post, a second battery post, and an electrode core. The housing is provided with an opening. The cover plate covers the opening. The electrode core is disposed inside the housing. The cover plate includes a cover plate body and a concave cavity portion that is concave inward relative to an outer surface of the cover plate body. The first battery post is accommodated in the concave cavity portion. A first electrode tab of the electrode core is electrically connected to the first battery post. The second battery post is electrically connected to the cover plate body. A second electrode tab of the electrode core is electrically connected to the cover plate body.

Battery unit, battery module and vehicle

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 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.
