Description
本創作係有關於一種電池模組,尤指一種極耳不易產生扭曲變形,且具有良好的導電效率並方便更換電池包的電池模組。This creation is about a battery module, especially a battery module whose tabs are not easily distorted, have good electrical conductivity, and are convenient to replace battery packs.
鋰鐵電池由於能源轉換效率高、使用壽命長、穩定性高等優勢,逐漸被廣泛地應用於各式電子產品中,而為了輕量化避免在使用時鋰鐵電池內部產生壓力異常的問題,廠商大多會採用具有延展性的軟質袋體來作為鋰鐵電池的外包裝,即軟包電池(Laminate Polymer Battery or Polymer Battery),並且能夠依照不同電力的需求與其它軟包電池串聯或並聯,從而構成一電池模組來作為電子裝置的電源。Due to the advantages of high energy conversion efficiency, long service life and high stability, lithium iron batteries are gradually being widely used in various electronic products. A ductile soft bag body will be used as the outer packaging of the lithium iron battery, that is, a soft pack battery (Laminate Polymer Battery or Polymer Battery), and it can be connected in series or parallel with other soft pack batteries according to different power requirements, thus forming a battery pack. The battery module is used as a power source for the electronic device.
一般的軟包電池在進行串聯或並聯時,通常是將各軟包電池的極耳和電極柱以銲錫銲接的方式來作連接。然而,各軟包電池的極耳為了和電極柱搭接,極耳便常會產生扭曲變形,且距離電極柱越外側的軟包電池極耳尤是,造成極耳扭曲變形處的電阻阻抗會大幅提升,使得極耳扭曲變形處的溫度增加,並且因為剪應力的產生而斷裂,從而導致軟包電池的導電效率不佳、使用壽命低、不易更換及維修困難等問題。When a general pouch battery is connected in series or parallel, the tabs and electrode posts of each pouch battery are usually connected by soldering. However, in order for the tabs of each pouch battery to overlap with the electrode posts, the tabs are often twisted and deformed, and especially the tabs of the pouch batteries that are farther outside the electrode post, the resistance impedance at the distorted and deformed part of the tabs will be greatly increased. Lifting, the temperature at the twisted deformation of the tab increases, and it breaks due to shear stress, which leads to problems such as poor electrical conductivity, low service life, and difficulty in replacement and maintenance of the pouch battery.
有鑑於此,本創作人遂針對上述現有技術的缺失,特潛心研究並配合學理的運用,盡力解決上述之問題點,即成為本創作人改良之目標。In view of this, the creator of the present invention has devoted himself to the research and application of the theory, aiming at the above-mentioned deficiencies of the prior art, to try his best to solve the above-mentioned problems, which has become the goal of the creator's improvement.
本創作之主要目的,在於使極耳不易產生扭曲變形,且電池模組能夠具有良好的導電效率及使用壽命並方便更換電池包。The main purpose of this creation is to make the tabs less likely to be twisted and deformed, and the battery module can have good electrical conductivity and service life, and it is convenient to replace the battery pack.
為了達成上述之目的,本創作提供一種電池模組,包括一絕緣基座、一對電極及複數電池包,各電極係設於絕緣基座,每一電極具有一搭接部及外露於絕緣基座的一接線部,每一電池包平順延伸有一對極耳,至少一部份的該些極耳的末端分別貼附於相對應的各搭接部。In order to achieve the above-mentioned purpose, the present invention provides a battery module including an insulating base, a pair of electrodes and a plurality of battery packs, each electrode is mounted on the insulating base, and each electrode has an overlap portion and is exposed on the insulating base In a connection part of the seat, each battery pack has a pair of tabs extending smoothly, and at least a part of the ends of the tabs are respectively attached to the corresponding overlapping parts.
本創作還具有以下功效:藉由接線部朝遠離搭接部的方向垂直延伸的螺柱,能夠方便使用者進行接線作業。透過串聯電極夠將不同電池包的正極耳和負極耳連接,從而讓二電池包達到串聯連接。藉由貼附在各電池包側邊及極耳外側的絕緣膠帶,能夠初步固定各電池包和極耳。透過串聯電極的轉折段凸設有穿出基板的檢測柱,能夠方便量測電壓及電流以在不拆卸電源模組的情況下得知電路是否正常。藉由裝設在電池包外的外殼作為保護,能夠避免電池包變形或是受損。The invention also has the following effects: the studs extending vertically from the wiring portion to the direction away from the overlapping portion can facilitate the user to perform wiring operations. The positive and negative terminals of different battery packs can be connected through the series electrodes, so that the two battery packs can be connected in series. The battery packs and the tabs can be preliminarily fixed by the insulating tapes attached to the sides of the battery packs and the outside of the tabs. The turning section of the series electrode is protruded with a detection column extending out of the substrate, so that the voltage and current can be easily measured so as to know whether the circuit is normal without disassembling the power module. The battery pack can be prevented from being deformed or damaged by the casing installed outside the battery pack as protection.
