Embodiment 1

[0033] refer to Figure 1-3 , a foaming process for an integrated battery pack, comprising the steps of:

[0034] S1: Foaming at the bottom of the box, place polyurethane on the bottom of the box to make it foam;

[0035] S2: Fix the battery, install and fix the first layer of battery on the upper part of the first layer of foam;

[0036] S3: The first layer of battery is foamed. After installation and fixing, the first layer of battery is foamed under the action of polyurethane;

[0037] S4: Interlayer foaming, after the first layer of battery cells are foamed, interlayer foaming is performed, so that the polyurethane does not pass through the first layer of batteries;

[0038] S5: Place the second layer of batteries, place the second layer of batteries on the foamed polyurethane of the interlayer, and fix them;

[0039] S6: The second layer of battery is foamed, and the second layer of battery is foamed after fixing;

[0040] S7: The upper layer is foamed, so that the po...

Abstract

The invention discloses a foaming process of an integrated battery pack. The foaming process comprises the following steps of S1, foaming a box bottom, namely putting polyurethane at the bottom of a box body, and enabling the polyurethane to carry out foaming work; S2, fixing a battery, namely mounting and fixing a first layer of battery at the upper part of a first layer of foaming body; S3, foaming the first layer of battery, namely after mounting and fixing, carrying out foaming work on the first layer of battery under the action of the polyurethane; S4, foaming an interlayer, namely afterfoaming the first layer of battery, carrying out interlayer foaming, so as to enable the polyurethane to submerge the first layer of battery; and S5, placing a second layer of battery. According to the foaming process disclosed by the invention, the battery can be sufficiently protected and the resistance of the battery is improved; the battery can be used in high-cold and high-heat places, so that the use applicability of the battery is improved; enough intervals can be used for resisting heat conduction and preventing the battery from being damaged by overheating; enough polyurethane foaminglayer intervals also can be used for providing enough support; the foaming process has the advantages of better safety, excellent insulating property and good heat insulation property.

Description

technical field [0001] The invention relates to the technical field of battery pack foaming, in particular to a foaming process for an integrated battery pack. Background technique [0002] With the development of the lithium battery industry, the competition industry is becoming more and more fierce, and the industry profits are getting lower and lower. All companies are looking for ways to shorten the battery production time, simplify the battery production process, and reduce the cost of manpower and material resources on the premise of ensuring the quality of lithium batteries. [0003] Due to the immature foaming process of many battery packs, the batteries cannot be used in the cold regions of Northeast China or the high-temperature regions of South China. The insulation is not good enough, the heat insulation is not good, and the accuracy is not high. There are problems in the design of the thickness of the polyurethane layer during foaming, the formulation of the fo...
