Embodiment Construction

[0039] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0040] see figure 1 , is a three-dimensional exploded schematic view of an embodiment of the battery module of the present invention. As shown in the figure, the battery module 10 mainly includes a plurality of battery cells 11, at least one conductive sheet 13 and at least one plastic protective layer 15, wherein the conductive sheet 13 is used to connect multiple battery cells 11 in series and / or in parallel, and the plastic protective layer 15 is disposed on a partial area of ​​the conductive sheet 13 by injection molding.

[0041] In an embodiment of the present invention, multiple battery cells 11 may be arranged in a matrix, wherein the battery cells 11 are arranged along a first direction X and a second direction Y, and the first direction X is perpendicular to the second direction Y. The arrangement directions of the...

Abstract

The invention provides a battery module which comprises a plurality of battery cells, a plurality of conducting strips and at least one plastic protective layer, and each conducting strip is respectively connected with the plurality of battery cells in series and / or in parallel. The plastic protective layers are arranged on part of the surfaces of the conducting strips in an injection molding mode, the situation that the temperature of the battery cell is increased abnormally and then the battery cell is burnt or exploded due to the fact that electrolyte sprayed out of the faulted battery cellmakes contact with the large-area conducting strips is avoided, and the safety of the battery module is improved.

Description

technical field [0001] The invention provides a battery module, which can prevent the electrolyte solution ejected from a faulty battery core from contacting a large-area conductive sheet and a protection unit, causing the temperature of the battery core to rise abnormally, and is beneficial to improving the safety of the battery module. Background technique [0002] Secondary batteries mainly include nickel-metal hydride batteries, nickel-cadmium batteries, lithium-ion batteries, and lithium-polymer batteries. Lithium batteries have high energy density, high operating voltage, wide operating temperature range, no memory effect, long life, and can be recharged many times. Discharge and other advantages, and are widely used in portable electronic products such as mobile phones, notebook computers, digital cameras, etc., and in recent years have expanded to the automotive field. Generally, a plurality of battery cells (Cells) are connected to form a battery pack, and the serie...
