Example Embodiment

[0038] Such as Figure 1 to Figure 8 Shown is an embodiment of the battery module of the present invention. In order to improve the heat dissipation capacity of the battery module, a temperature adjustment element capable of adjusting the temperature of the battery pack is directly attached to the bottom surface of the battery pack. The battery module includes two parts, namely the battery pack 1 and a module frame arranged on the outside of the battery pack 1. The battery pack 1 is formed by stacking a plurality of battery cells 11 in turn, and between each battery cell 11, The structural adhesive is bonded to ensure the fixing effect of the battery pack 1. On the front, rear, left, and right sides of the battery pack 1, end plates and side plates are respectively provided to protect and insulate the battery pack 1. In the stacking direction of the battery pack 1, that is, in the front and rear directions in the figure. An end plate is provided, and the end plate includes an ...

Abstract

The invention relates to the technical field of power batteries, in particular to a battery module. The battery module comprises a module framework and a battery pack which is arranged in the modularframework and formed by arranging single batteries and further comprises a temperature adjusting component for heating and/or cooling the battery pack; and an installation hole is formed in the bottomof the module framework, the bottom of the battery pack is exposed in the installation hole, and the temperature adjusting component is arranged in the installation hole and arranged on the bottom face of the battery pack in an attached mode. Due to the fact that the installation hole is formed in the bottom of the module framework, technical staff can directly arrange the temperature adjusting component in the installation hole in the attached mode; due to the fact that the module framework can support the battery pack, the technical staff do not need to arrange a bottom plate forming complete closure on the overall bottom face of the battery module; and due to the fact that the temperature adjusting component directly makes contact with the bottom of the battery pack, the heat conducting loss is reduced, assembly parts of the overall battery module are reduced, and therefore the battery module is lighter and good in heating or cooling effect.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery module. Background technique [0002] Under the huge challenge of the current global energy shortage and deteriorating environment, the development of electric vehicles, the realization of zero-emission of vehicle energy and power systems, and the promotion of the popularization of electric vehicles have formed a broad international consensus. The on-board battery is the most important part of an electric vehicle. The battery is assembled from multiple battery modules, so the stability of a single battery module determines the performance of an electric vehicle. [0003] The authorized announcement number is CN203631621U, and the authorized announcement date is 2014.06.04. The Chinese utility model patent discloses a battery module, including a battery assembly assembly and a metal base assembly. The battery assembly assembly includes a plurality of battery cell...
