Description
本創作係有關一種電池模組電極串接結構改良，尤指一種以鋁絲線材焊接技術對電池模組中之電池正極或負極與導電板間做串並焊接連結，可使鋁絲線材之阻抗大幅降低，並節省加工時間及降低生產成本之電池模組電極串接結構設計。 This invention relates to an improvement in the series connection structure of battery module electrodes, especially a series-parallel welding connection between the battery positive or negative electrodes and the conductive plate in the battery module using aluminum wire wire welding technology, which can improve the impedance of the aluminum wire. The battery module electrode series connection structure design significantly reduces processing time and production costs.
按，習知電池模組4中電池41正極411及負極412之串並聯方式，如第四圖及第五圖所示，一般均採用面積較大之鎳片5作為電池41正極411及負極412之串並聯材料，而在進行鎳片5焊接時一般均採用點焊，而點焊加工即是一種電組焊，而即係因鎳片5須具有電阻才能使用電組焊，且一般來說，鎳片5之電阻約是銅的100倍，因此，習知以鎳片5作為電池模組4中電池41正極411及負極412串並聯連接之材料，其具有高阻抗，而使電池41之電流在經過一連串的鎳片5後，已被抵消了一部分，進而使電池41之供電效率大幅降低，而使用鎳片5之成本高，且鎳片5熔融溫度較高，遇電池41間產生異常大電流而升溫時，鎳片5無法產生熔斷而斷開電流，致使電池41因此損壞或產生***之危險。 According to the conventional series-parallel connection method of the positive electrode 411 and negative electrode 412 of the battery 41 in the battery module 4, as shown in the fourth and fifth figures, a nickel sheet 5 with a larger area is generally used as the positive electrode 411 and negative electrode 412 of the battery 41. Series and parallel materials, spot welding is generally used when welding nickel 5, and spot welding is a kind of electric assembly welding, and that is because the nickel 5 must have resistance before electric assembly welding can be used, and generally speaking The resistance of the nickel sheet 5 is about 100 times that of copper. Therefore, it is commonly known that the nickel sheet 5 is used as the material for connecting the positive electrode 411 and the negative electrode 412 of the battery 41 in the battery module 4 in series and parallel. It has high impedance, so that the battery 41 After the current passes through a series of nickel sheets 5, part of it has been offset, thereby greatly reducing the power supply efficiency of the battery 41. The cost of using nickel sheets 5 is high, and the melting temperature of the nickel sheets 5 is high, and abnormality occurs when encountering the battery 41. When the temperature rises due to a large current, the nickel sheet 5 cannot fuse and cuts off the current, causing the battery 41 to be damaged or causing the risk of explosion.
本創作人有鑑於上述習知電池模組中電池正極及負極之串並聯方式之實用困難及有待改善之缺失，盼能提供一突破性之設計，以增進實用效果，乃潛心研思、設計組製，綜集其多年從事相關產品設計產銷之專業技術知識與實務經驗及研思設計所得之成果，終研究出本創作一種電池模組電極串接結構改良，以提供使用者。 In view of the practical difficulties and deficiencies that need to be improved in the series-parallel connection of the battery positive and negative electrodes in the conventional battery module, the creator hopes to provide a breakthrough design to enhance practical effects, and has devoted himself to research and design. Based on his many years of professional technical knowledge and practical experience in related product design, production and sales, as well as the results obtained from research and design, he finally developed an improved battery module electrode series connection structure to provide users with this product.
