Embodiment approach 2
[0058] see Figure 7-10 , shows the battery module and the installation method according to Embodiment 2 of the present invention, and the heat dissipation effect of the method is remarkable. At the same time, this connection method does not need to use tooling.
[0059] The module includes a rechargeable lithium-ion power battery 1, an insulating plate 2, a binding plate 6, a side binding plate 11, an upper binding plate 12, and a fan 13, and the batteries are connected by pole plates 5.
[0060] Wherein, the side restraint plate 11 can replace the function of the side plate 9 in the tooling, and the distance between the two restraint plates 6, that is, the distance between each battery 1 can be ensured by adjusting the length of the side restraint plate 11. The binding plate 6 can be heightened to leave a space for accommodating the fan 13 .
[0061] The handle of the binding plate 6 can be punched according to the position of the hole on the bottom surface, so that the ho...

Abstract
A lithium-ion power battery module, an assembly method, and supporting tooling, comprising an arrangement composed of a plurality of rechargeable lithium-ion power batteries (1) and a plurality of insulating plates (2) arranged alternately with the batteries (1), Two binding plates (6) are arranged on the outermost side of the arrangement; it is characterized in that it also includes: a binding layer (4), the two ends of which are respectively connected with the two left and right binding plates (6), and are used to control the two binding plates (6) from above. The battery (1) is limited; the throat clamp (7) is fastened around the battery module to determine the length of the battery module and limit the movement of the battery 1 in the horizontal direction.
Description
technical field [0001] The invention relates to a rechargeable battery module, in particular to a lithium-ion power battery module, an assembly method and supporting tooling. Background technique [0002] As the global energy crisis has become increasingly prominent in recent years, the development and application of new energy has become the focus of research by scientific and technological personnel. Among them, rechargeable battery technology has developed rapidly, including lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries, etc. . Rechargeable batteries are widely used not only in portable electronic devices such as mobile phones, digital cameras and laptop computers, but also in electric vehicles, hybrid vehicles, large charging power sources, secondary charging and energy storage devices, etc. [0003] Lithium-ion battery is the world-recognized preferred power for new energy vehicles, with high voltage and long cycle life; excellent rate p...
