Embodiment Construction

[0017] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0018] see figure 1 , the present invention provides a kind of processing technology of automobile power battery copper bar, comprises the following steps:

[0019] S1: Process the insulating material to the required size;

[0020] S2: The processed insulating material is distributed on both sides of the copper bar, and stacked according to the structure of insulating material-copper bar-insulating material to obtain a pre-stack;

[0021] S3: placing the pre-stacked object on a heat press machine for heat press treatment;

[0022] S4: Remove excess scrap and residual glue.

[0023] First in step S1, the insulating material is a PI insulating material, and the PI insulating material has a three-layer structure, including a PI film, an adhesive layer and a release paper, and the adhesive layer is located between ...

Abstract

The invention discloses a machining technology for a car power battery copper bar. The technology comprises the following steps that (1), insulating materials are machined to have the needed sizes; (2), the machined insulating materials are distributed on the two sides of the copper bar, stacking is conducted according to the insulating material-copper bar-insulating material structure, and a pre-stacked material is obtained; (3), the pre-stacked material is arranged on a hot press to be subjected to hot pressing treatment; and (4), redundant leftover materials and residual glue are removed. According to the machining technology for the car power battery copper bar, a conventional copper bar thermoplastic casing pipe is replaced with an electronic-grade flexible insulating material, the material is smaller in thickness and good in insulativity compared with a traditional copper bar protecting sleeve, moisture prevention and humid prevention can be effectively achieved, and the machining technology is a more reliable car power battery copper bar insulating protection technology.

Description

technical field [0001] The invention relates to the field of automobile batteries, in particular to a processing technology for copper bars of automobile power batteries. Background technique [0002] With the society's attention and vigilance to energy depletion and environmental pollution, the market demand for power battery vehicles is huge. Most countries have begun to encourage the development of clean energy technologies in terms of policies to deal with the deteriorating human living environment and potential fossil energy crises. In this context, new energy technologies, especially in the field of battery energy storage technology, have developed commercialized energy storage products with the joint efforts of the government, business circles and academia, which has also brought hybrid vehicles and The popularity and popularity of pure electric vehicles. Common automotive power battery systems are usually composed of multiple battery packs connected in series, which...
