Description

電池模組battery module

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.

該對電極20包括一正極21及一負極22，且各電極20皆為銅片，但本創作不以此為限，只要係具有良好導電性的金屬片體即可。各電極20係直立設於絕緣基座10，且每一電極20具有一搭接部23及外露於絕緣基座10的一接線部24。具體而言，各搭接部23係嵌設在絕緣基座10，而各接線部24係凸出並外露在基板11的上方。於本實施例中，每一接線部24係自相對應的搭接部23垂直彎折，使各接線部24水平貼附在絕緣基座10的基板11外表面，但本創作不以此為限，例如各接線部24和對應的各搭接部23也可以為同一平面的無彎折片體而共同垂直於基板11。較佳地，各接線部24還可分別朝遠離各搭接部23的方向垂直延伸有一螺柱241，從而能夠方便使用者進行接線作業。又，於本實施例中，各搭接部23係位在隔牆12的左右兩側，但本創作不以此為限，例如各搭接部23也可以位於隔牆12內，或是各搭接部23也可以皆位於隔牆12的同一側，端看設計上的需求來作調整。The pair of electrodes 20 includes a positive electrode 21 and a negative electrode 22, and each electrode 20 is a copper sheet, but the invention is not limited to this, as long as it is a metal sheet body with good electrical conductivity. Each electrode 20 is erected on the insulating base 10 , and each electrode 20 has an overlapping portion 23 and a wiring portion 24 exposed on the insulating base 10 . Specifically, each overlapping portion 23 is embedded in the insulating base 10 , and each wiring portion 24 is protruded and exposed above the substrate 11 . In this embodiment, each wiring portion 24 is vertically bent from the corresponding overlapping portion 23, so that each wiring portion 24 is horizontally attached to the outer surface of the substrate 11 of the insulating base 10, but this is not the case in this invention.

以下針對電池模組中不同電池包30數量的連接方式來作說明：The following describes the connection methods of different numbers of battery packs 30 in the battery module:

當電池包30的數量為二且為並聯連接時，其中一電池包30的正極耳311係對應正極21的搭接部23貼附作連接，而負極耳312則是對應負極22的搭接部23貼附作連接，且正極21和負極22的二搭接部23較佳地係位於隔牆12的同一側或隔牆12的內部而能夠讓電池包30保持縱向設置。而另一電池包30之正極耳311係貼附連接在先前的電池包30的正極耳311外側，負極耳312則是貼附連接在先前的電池包30的負極耳312外側。藉此各正極耳311皆和正極21電性連接，各負極耳312皆和負極22電性連接，從而讓二電池包30能夠達到並聯的效果。When the number of battery packs 30 is two and connected in parallel, the positive tab 311 of one of the battery packs 30 is attached to the lap portion 23 of the positive electrode 21 for connection, and the negative tab 312 corresponds to the lap portion of the negative electrode 22 . 23 is attached for connection, and the two overlapping parts 23 of the positive electrode 21 and the negative electrode 22 are preferably located on the same side of the partition wall 12 or inside the partition wall 12 so that the battery pack 30 can be kept vertically arranged. The positive tab 311 of the other battery pack 30 is attached to the outside of the positive tab 311 of the previous battery pack 30 , and the negative tab 312 is attached to the outside of the negative tab 312 of the previous battery pack 30 . Therefore, each of the positive electrodes 311 is electrically connected to the positive electrode 21 , and each of the negative electrodes 312 is electrically connected to the negative electrode 22 , so that the two battery packs 30 can be connected in parallel.

當電池包30的數量為二且為串聯連接時，本創作之電池模組還可包括一串聯電極50。串聯電極50為具有良好導電性的金屬片體，其係設於絕緣基座10的隔牆12。具體而言，串聯電極50概呈閃電狀從而具有位在隔牆12左右兩側的二銲接段51及埋設在隔牆12內的一轉折段52。其中一電池包30的正極耳311和另一電池包30的負極耳312分別貼附連接在二銲接段51，其餘的另一負極耳312及另一正極耳311則分別貼附連接在負極22的搭接部23及正極21的搭接部23，藉此便能夠透過串聯電極50夠將二電池包30作串聯連接。於本實施例中，串聯電極50係由鋅、銅、銀、鉛或錫等金屬所混合製成的複合材料片，且各金屬的比例可依照不同需求的電流界值來做相對應的調整，因此本發明不對此做限制。藉此當電流在超過一定的界值時便能夠產生融斷機制，從而避免過大的電流影響其他電池包30以及整體的電路，並阻斷各電池包30間的串聯連接以防止其他電池包30亦產生被破壞的連鎖反應。When the number of battery packs 30 is two and connected in series, the battery module of the present invention may further include a series electrode 50 . The series electrode 50 is a metal sheet body with good electrical conductivity, and is attached to the partition wall 12 of the insulating base 10 . Specifically, the series electrode 50 is generally in the shape of a lightning bolt and has two welding sections 51 on the left and right sides of the partition wall 12 and a turning section 52 embedded in the partition wall 12 . The positive tab 311 of one battery pack 30 and the negative tab 312 of the other battery pack 30 are attached and connected to the second welding section 51 respectively, and the other negative tab 312 and the other positive tab 311 are attached and connected to the negative electrode 22 respectively The overlapping portion 23 of the positive electrode 21 and the overlapping portion 23 of the positive electrode 21 can connect the two battery packs 30 in series through the series electrode 50 . In this embodiment, the series electrode 50 is a composite material sheet made of a mixture of metals such as zinc, copper, silver, lead or tin, and the ratio of each metal can be adjusted according to different current thresholds. , so the present invention does not limit it. In this way, when the current exceeds a certain threshold, a fuse mechanism can be generated, so as to prevent the excessive current from affecting other battery packs 30 and the overall circuit, and block the series connection between the battery packs 30 to prevent other battery packs 30 from being connected in series. There is also a chain reaction that is destroyed.

當電池包30的數量為四，且各電池包30係以兩兩為一組並聯後再作串聯時，大致上和二電池包30的串聯連接方式相同，差別僅在於多出的二電池包30係分別位於左右兩側，且多出的二電池包30的正極耳311和負極耳312係分別貼附連接在其相鄰的電池包30的正極耳311和負極耳312的外側。藉此多出的二電池包30便能夠分別和原先串聯的二電池包30作並聯連接，從而達到兩組並聯電池包30串聯連接的效果。When the number of battery packs 30 is four, and the battery packs 30 are connected in parallel in groups of two and then connected in series, the connection method is basically the same as the series connection of two battery packs 30 , the difference is only the extra two battery packs 30 are located on the left and right sides respectively, and the positive tab 311 and the negative tab 312 of the extra two battery packs 30 are attached to the outside of the positive tab 311 and the negative tab 312 of the adjacent battery pack 30 respectively. Thereby, the extra two battery packs 30 can be respectively connected in parallel with the two battery packs 30 originally connected in series, so as to achieve the effect that two parallel battery packs 30 are connected in series.

進一步說明，在串聯電極50的轉折段52凸出設置有穿出絕緣基座10基板11的一檢測柱521，藉此能夠方便使用者量測電壓及電流，從而在不拆卸電源模組的情況下便能夠得知各電池包30之間的電路是否正常，但本創作不特定限制檢測柱521的位置。又，本創作之電池模組還可包括一外殼60。外殼60為一中空殼體並且具有一開口61。絕緣基座10的基板11係封合於開口61而將基板11遠離隔牆12的外表面裸露在外殼60的外部，使得電池包30能夠容置在外殼60內作為保護以避免電池包30變形或受損，同時各搭接部23也容置在外殼60內而僅有接線部24裸露在外以供使用者進行接線。較佳地，電池模組還可包括複數螺栓A。在絕緣基座10的隔牆12的前後兩側邊分別設有一鎖孔121，外殼60則對應各鎖孔121的位置分別設有一通孔62，各螺栓A係穿過對應的各通孔62後鎖固於各鎖孔121，藉此便能夠將外殼60和絕緣基座10兩者固定，並且方便維修人員快速將電池包取出維修或更換。It is further explained that a detection column 521 is protruded from the turning section 52 of the series electrode 50 and protrudes through the substrate 11 of the insulating base 10 , so as to facilitate the user to measure the voltage and current without disassembling the power module. It can be known whether the circuit between the battery packs 30 is normal or not, but the present invention does not specifically limit the position of the detection column 521 . In addition, the battery module of the present invention may further include a casing 60 . The housing 60 is a hollow shell and has an opening 61 . The substrate 11 of the insulating base 10 is sealed in the opening 61 so that the outer surface of the substrate 11 away from the partition wall 12 is exposed outside the casing 60 , so that the battery pack 30 can be accommodated in the casing 60 as a protection to avoid deformation of the battery pack 30 At the same time, each overlapping portion 23 is also accommodated in the casing 60, and only the wiring portion 24 is exposed outside for the user to wire. Preferably, the battery module may further include a plurality of bolts A. A locking hole 121 is respectively provided on the front and rear sides of the partition wall 12 of the insulating base 10 , and a through hole 62 is respectively defined in the housing 60 corresponding to each locking hole 121 , and each bolt A passes through the corresponding through hole 62 . The rear is locked in each locking hole 121 , so that both the casing 60 and the insulating base 10 can be fixed, and it is convenient for maintenance personnel to quickly take out the battery pack for maintenance or replacement.
