1295863 \ - 九、發明說明: 【發明所屬之技術領域】 本發明為關於一種具有創新結構之電池匣,以及包含 該電池匣的一種開放式電池模組,尤指一種電池匣,其包 含兩個外框構件,及置於該等外框構件之間的一内框構 件,其中一或多個電池單元裝設於該等外框及内框構件之 : 間,且該内框構件具有通孔,以及包含該電池匣之開放式 - 電池模組。 【先前技術】 近年來,可以放電及充電的二次電池已被廣泛地做為 無線行動裝置的能源。同時,該二次電池因為做為電動車 及複合式電動車之能源而引起相當的重視,其已被開發出 來解決像是由於既有之使用石油的汽油及柴油車輛所造成 之空氣污染的問題。 Φ 小尺寸的行動裝置使用一或多個電池單元,例如每個 裝置有三或四個電池單元。相反地,中型或大型裝置(例如 車輛)使用一中型或大型電池系統,其中包含彼此電路連接 之複數個電池單元,因為其需要一高輸出及大容量的電池。 因為該中型或大型電池系統之電池單元廣泛地被使 用,一袋形二次電池,其通常包裝在由一鋁及聚合物樹脂 所構成的疊層板製成的電池殼當中,因此該袋形二次電池 之機械強度並不高。因此,複數個電池單元安裝在一電池 匣中,其中該等電池單元即串聯或並聯連接,且複數電池 1295863 \ 匣彼此電路連接構成一電池模組。 廣泛用於複合式電動車之電池模組具有一封閉的結 構,其中電解質不會由每個電池單元(二次電池)中漏出。 也就是說,該密閉形式的電池模組之好處在於防止電解質 之洩漏。但是,該封閉型電池模組之問題在於電池單元中 所產生的熱量會累積,且該累積的熱量會加速電池之劣 : 化,且小量或大量的電池單元在當其異常運作時會過熱, , 因此該等電池單元會著火或爆炸。鋰離子二次電池或鋰離 子聚合物二次電池,其在當該二次電池充電及放電時會產 生熱量,其已經引起對於電池單元的可能用途更多的注 意。當這些熱量持續地累積在該電池單元中時,即會加速 該電池單元之劣化,另外該電池單元會著火或爆炸。 因此,其有需要提供一種中型或大型的電池系統,其 能夠穩定地安裝具有低機械強度之電池單元,有效地自該 等電池單元中移除熱量,並在當其異常運作時防止該等電 Φ 池單元之過熱現象,藉此可以改善該等電池單元之壽命及 安全性。 【發明内容】 因此本發明的目的在於實質地減輕上述習用技術中的 問題,以及過去所遭遇到的技術問題。 本發明第一目的在於提供一種電池匣,其具有較高的 結構整合性及機械強度,藉此可最小化一電池系統之尺 寸,穩定地裝置具有低機械強度之電池單元,有效地移除 1295863 來自該等電池單元之熱量,並防 本菸明筮-口 令也池早兀過熱。 電池E :”;等供一電池模組,其中包括複數 八中忒4電池匣安裝在該電池模袓 整合性及機械強度,並可達到有效的執量移=南的 池模組可以用於—高輸出、大容量⑽系統Γ該電 ϋ來=本:二士述及其它的目的可由所提供的-電池 ι單元,及〇卜框構件(a,b),用於收納電池 1其中該等兩也⑷’其置於該等外框構件(a,b)之間, 框構件(0之間,复它帝、m〇卜忙構件⑷與該内 與該内框構件(c二早广以在該第二外框構件(b) 其可連通到::)之 構件之間。 早兀係裝設於該外框與内框
