Embodiment Construction

[0020] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] The battery assembling process of the present invention is to use the batteries of the same model or similar performance as the battery cells of the battery module, and coat the surface of the battery cells with thermally conductive glue, and then apply the thermally conductive glue to the battery cells. The battery cells are combined in parallel according to the order of positive and negative poles, as a set of battery cells, put the battery cells into the battery rack. Among them, it should be noted that the positive and negative poles of the battery cells placed in the battery rack are detected, and the posit...

Abstract

The invention relates to the technical field of a power battery and specifically relates to an assembling technique for a new energy power battery. The assembling technique comprises the following steps: selecting battery monomers with similar properties; coating the surfaces of the battery monomers with heat-conducting glue; combining the battery monomers in the sequence of positive electrode and negative electrode, thereby forming a set of battery cells; connecting the positive electrodes and negative electrodes of the battery monomers in parallel through nickel sheets and welding; performing shell laser welding on the set of battery cells, thereby forming battery modules; combining and assembling the battery modules, thereby forming a battery mold. According to the invention, the heat-conducting glue coats the surfaces of the battery monomers, so that the heat in the battery can be efficiently educed, the problem of battery swelling or short service life of the battery caused by the heat failed to be timely educed when the temperature of the battery is ultrahigh can be solved and the battery technique according to the scheme is simple and efficient.

Description

Technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery assembly process. Background technique [0002] Now hybrid vehicles and electric vehicles are entering people's lives. The power battery used in electric vehicles is regarded as a battery with high voltage, high energy, high capacity and high density. This type of battery is a battery pack formed by interconnecting multiple battery cells, and the battery pack is connected in series. [0003] The efficiency and lifespan of the battery pack device largely depends on the temperature environment. When the high temperature is reached, the efficiency and life of the battery pack device will decrease. In addition, when the temperature of the cells constituting the battery pack device varies, there is a problem of adversely affecting the output characteristics and life. Summary of the invention [0004] In order to overcome the above technical shortcomings, the present inve...
