隨著綠能科技的進步,由大量蓄電池組成的儲能系統的相關應用已越來越普及於各種電力系統當中,例如:電動載具、緊急備用系統、再生能源系統、智慧電網或家用儲能設備等。 With the advancement of green energy technology, the application of energy storage systems composed of a large number of batteries has become more and more popular in various power systems, such as: electric vehicles, emergency backup systems, renewable energy systems, smart grids, or home energy storage Equipment etc.

一般電池管理裝置包含電池組與電池管理單元,其中電池管理單元包含電壓量測線與電芯平衡線。而傳統之電壓量測線與電芯平衡線以往在連接時,通常是使用多芯線、Y\O型端子及連接座進行線路配置,方能連結至電池組,而在單電芯極柱上同時存在於多個連接節點。在此種結構下,電池管理單元於作動時會因連接節點上之電壓小損失而造成電壓量測的誤差,此誤差可能導致電池管理單元的錯誤判斷而促使異常狀態及危險的發生。再者,由於一般習知 的電路板與電池組在使用多芯線、Y\O型端子或連接座完成連接之後,須額外進行電路板的定點固定,以避免電路板因外部力量而造成線路之脫離。然而,這種額外之固定方式往往會大幅增加安裝者於裝設過程中的裝設複雜度與裝設時間。 A general battery management device includes a battery pack and a battery management unit, where the battery management unit includes a voltage measurement line and a cell balance line.

Under this structure, when the battery management unit is in operation, an error in voltage measurement may be caused by a small loss of voltage on the connection node. This error may cause an erroneous judgment of the battery management unit and promote the occurrence of abnormal conditions and dangers. In addition, since the conventional circuit board and battery pack are connected using multi-core wires, Y\O-type terminals or a connector, the fixed point of the circuit board must be additionally fixed to avoid the circuit board from being caused by external forces.

金屬連接單元裝設步驟S2係裝設金屬連接單元300之第一連接部310於電池組200,令金屬連接單元300固定地連接電池組200。在金屬連接單元裝設步驟S2中,將各第一連接部310之第一孔洞3102對齊電池組200之電極,然後驅動第一固定件500分別對應貫穿第一孔洞3102而螺鎖於電池組200之電極。也就是說,透過第一固定件500可將金屬連接單元300牢固地定位於電池210上。 The metal connection unit installation step S2 is to install the first connection part 310 of the metal connection unit 300 on the battery pack 200 so that the metal connection unit 300 is fixedly connected to the battery pack 200. In the mounting step S2 of the metal connection unit, the first holes 3102 of the first connection parts 310 are aligned with the electrodes of the battery pack 200, and then the first fixing members 500 are driven to penetrate the first holes 3102 respectively and are screwed to the battery pack 200之electrode. In other words, the metal fixing unit 300 can be firmly positioned on the battery 210 through the first fixing member 500.

電池管理單元裝設步驟S4係裝設電池管理單元400於金屬連接單元300之第二連接部320,令電池管理 單元400固定地連接金屬連接單元300。在電池管理單元裝設步驟S4中,將各第二連接部320之第二孔洞3202對齊其中一個連接節點412,然後驅動第二固定件600分別對應貫穿連接節點412及第二孔洞3202而螺鎖於電路板410上。也就是說,透過第二固定件600可將電路板410牢固地定位於金屬連接單元300上。藉此,本發明之電池管理單元的裝設方法800可以提高線路配置的製作效率。此外,由於一般習知的電路板410與電池組200在使用多芯線、Y\O型端子或連接座完成連接之後,須額外進行電路板410的定點固定,以避免電路板410因外部力量而造成線路之脫離,而本發明係將電路板410與電池組200之間採用銅製片狀的金屬連接單元300進行連結,不但可提高整體的牢固性,而且無須另外固定電路板410,既省時又省力。 The battery management unit installation step S4 is to install the battery management unit 400 on the second connection portion 320 of the metal connection unit 300, so that the battery management unit 400 is fixedly connected to the metal connection unit 300. In the step S4 of installing the battery management unit, the second holes 3202 of the second connection parts 320 are aligned with one of the connection nodes 412, and then the second fixing member 600 is driven to screw through the connection nodes 412 and the second holes 3202 respectively On the circuit board 410. That is, the circuit board 410 can be firmly positioned on the metal connection unit 300 through the second fixing member 600. In this way, the method 800 for installing the battery management unit of the present invention can improve the manufacturing efficiency of the circuit configuration. In addition, since the conventional circuit board 410 and the battery pack 200 are connected using multi-core wires, Y\O-type terminals or a connector, the fixed point of the circuit board 410 must be additionally fixed to avoid the circuit board 410 due to external forces The circuit is disconnected, and the present invention connects the circuit board 410 and the battery pack 200 with a copper sheet metal connection unit 300, which not only improves the overall robustness, but also does not need to additionally fix the circuit board 410, which saves time And effortless.
