Embodiment 2

[0039] In an unillustrated embodiment of the present invention, another fast cooling battery module is provided, and the structure of the fast cooling battery module is substantially the same as that of the battery module in the first embodiment. The main difference is that the battery module in Embodiment 1 is a battery module in which multiple single cells 10 are connected in series, while the battery module in this embodiment is a battery module in which multiple single cells 10 are connected in parallel. .

[0040] Specifically, in this embodiment, the positive and negative pole lugs 11 of a plurality of single battery cells 10 are respectively arranged in opposite rows, that is, the positive pole lug of one single battery cell 10 is connected to another adjacent single battery cell. The positive tab of the core 10 is arranged facing to each other, and the negative tab is arranged facing to the negative tab of another adjacent cell 10 . The positive tabs 11 of the plurali...

Abstract

The invention discloses a rapid heat dissipation battery module which comprises: a plurality of stacked single battery cells; battery cell heat-conducting insulating pads attached to the tabs of the single battery cells; a heat-conducting aluminum plate pressed and attached to the other surfaces of the battery cell heat-conducting insulating pads; a module heat-conducting insulating pad tightly pressed on the other surface of the heat-conducting aluminum plate; and a metal heat dissipation outer shell, wherein the single battery cells are accommodated in the metal heat dissipation shell, and the metal heat dissipation shell and the module heat conduction insulating pad are pressed and clung to each other. Compared with an existing heat dissipation mode that heat is transferred through an aluminum plastic film from the side face of a single battery cell, the rapid heat dissipation battery module is more direct and effective in heat dissipation, higher in heat dissipation efficiency andbetter in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a rapid heat dissipation battery module. Background technique [0002] In the application of new energy batteries, the ambient temperature of the battery is a key parameter for the use of battery modules. During the cycle charge and discharge process of the battery module, due to the internal resistance of the single cell itself, the cell generates heat during the cycle charge and discharge process. The internal resistance will increase significantly, and the heating of the battery will be more obvious. [0003] Excessive cell temperature will destroy the chemical balance inside the cell and cause side reactions. The performance of the battery material will be degraded under high temperature cycle charging and discharging, and the battery cycle performance will also be greatly reduced. Therefore, in the design of battery modules, heat dissipation design is a very ...
