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, 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.
