Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

The invention relates to an integration electrical core module, which comprises an electrical core group, wherein the electrical core group can be integrated to a tetragonal prism shape assembled by mutually connecting several electrical cores in series, and a current carrying sheet connected to the electrical core group and arranged on the transverse plane; a tab member which comprises a metal conductive matrix attached to the current carrying sheet and a tab vertically arranged to the metal conductive matrix; a transverse plane baffle plate which is covered on the transverse plane of the electrical core group and is used for abutting the tab member on the transverse plane of the electrical core group, wherein, a groove accommodating the tab is arranged at the transverse plane baffle plate; a side surface baffle plate covered at side surface of the electrical core group, wherein, the transverse plane baffle plate enables vertical bolt joint with the side surface baffle plate by employing a screw. The groove is capable of accommodating the tab of the tab member, the tab is positioned in the groove, so that hidden trouble can not generate due to outside force. According to the invention, the transverse plane baffle plate and the side surface baffle plate are arranged at the side surface and the transverse plane of the electrical core module, the electrical core module enables normal work under outside force and shock. The transverse plane baffle plate and the side surface baffle plate enable bolt joint, so that the electrical core module can be firmly fixed on three dimensional directions.
Description
technical field [0001] The invention relates to a battery module, in particular to an integrated battery module of 18650 batteries. Background technique [0002] The current battery module uses the same current carrier to achieve series connection and uses a single tab output, which reduces the reliability of the battery module. During the transportation and use of the battery module, if the tabs of the battery module exceed the outer space of the battery module, it is easy to break the tabs, resulting in poor stability of the battery module, or during use. Leakage short circuit occurs, resulting in danger. Contents of the invention [0003] Based on this, it is necessary to provide an integrated battery module with stable tabs and firm fixing of the battery module. [0004] An integrated cell module, including a cell group, the cell group is composed of a plurality of cells connected in series and assembled into a square column shape, and a current carrier connected to ...
