Abstract

The invention discloses a battery module rapid assembly and rapid heat dissipation structure, which includes a battery case, a bus bar, a heat dissipation component and a number of single batteries. The electrode structure of the single battery includes an electrode head, a flexible conductive part and an electrode sleeve. The electrode sleeve is set outside the electrode head. One end of the electrode head is exposed from the electrode sleeve and plugged into the electrode socket of the bus bar for electricity. The other end is welded and fixed with the electrode tab of the single battery through the flexible conductive part. There is a protruding part at the bottom of one side of the electrode socket, and the lower part of the electrode sleeve and the protruding part are clamped and fixed by the I-shaped fixing plug inserted from the side. The electrode cooling part, the electrode cooling part blocks the I-shaped fixing plug after the electrode structure is connected. The invention can make the battery assembly process simpler and more convenient under the premise of ensuring the safety and reliability of the connection of the battery electrodes, and is convenient for subsequent disassembly and maintenance.

Description

technical field [0001] The invention belongs to the technical field of batteries, and relates to a battery module rapid assembly and rapid heat dissipation structure. Background technique [0002] In new energy vehicles and other fields, a battery module formed by connecting multiple single batteries in series and parallel is usually used to supply power to ensure the voltage and power requirements. Parallel connection is generally connected by bolts, soldering or laser welding, among which the use of bolts is likely to cause a short circuit of the battery, and the number of single cells in the battery module is large. This solution requires too many bolts, which greatly increases the weight of the module. The welding connection method, the high temperature in the welding process is likely to cause the battery components to be heated and deformed, and it is difficult to disassemble and repair. Soldering requires more energy at the same time, and the production process is cum...
