电池模块CMT焊技术研究

近几年新能源行业出现井喷式发展,各动力电池厂、Pack集成厂为抢占市场,积极开发新型Pack集成技术。集成技术的关键技术指标之一为安全,电池模块作为Pack内关键零部件,其集成质量直接影响Pack安全性能。CMT焊技术由于其焊接强度高、抗震性能好、低热输入、无飞溅、易实现自动化、成本低的特点,被引入Pack集成领域,获得行业认可。文章重点研究CMT焊技术在电池模块集成方面的应用,介绍焊接技术指标、质量评价手段、常见缺陷成因、改善方案等。

In recent years, the new energy industry has a blowout development, power battery plants, Pack integration plants to seize the market, and actively develop new Pack integration technology. Safety is one of the key technical indexes of integration technology. Battery module is the key component of Pack, and its integration quality directly affects the safety performance of Pack. CMT welding technology because of its high welding strength, good seismic performance, low heat input, no splash, easy to achieve automation, low cost, has been introduced into the field of Pack integration, and has been recognized by the industry. This paper fo cuses on the application of CMT welding technology in battery module integration, introduces the welding technical indicators, quailU evaluation means, the causes of common defects, improvement programs and so on.
