Description
本實施例係相關於可攜式電子裝置的電池。尤其是,本實施例係相關於具有不同容量、厚度、及/或尺寸的電池之電池組。
可充電電池目前被用於提供電力給各種廣泛的可攜式電子裝置,包括膝上型電腦、行動電話、PDA、數位音樂播放器、及無線電力工具。最常見的可充電電池類型為鋰電池,其可包括鋰離子或鋰聚合物電池。
鋰聚合物電池通常包括封裝在撓性囊袋中之電池。此種囊袋典型上是輕量的且製造起來不昂貴。而且,囊袋可裁製成各種電池尺寸,使鋰聚合物電池可用於空間有限的可攜式電子裝置中,諸如行動電話,膝上型電腦、及/或數位相機等。例如,藉由將凍膠捲和電解液封在錫箔囊袋中,鋰聚合物電池可達成90-95%的封裝效能。多個囊袋然後可並排置放在可攜式電子裝置內及串聯及/並聯電耦合,以形成可攜式電子裝置的電池。
然而,空間的有效利用可能被侷限在現存電池組架構中之電池的配置。尤其是,電池組典型上包含相同容量、大小、及尺寸之電池。電池的實體配置可額外反映電池的電組態。例如,六個電池的電池組可包括組構成兩個串聯、三個並聯(2s3p)的組態之相同大小和容量的六個鋰聚合物電池。在電池組內,並排置放的兩列三個電池可堆疊在彼此頂部上;各列可電耦合成並聯組態,及兩列電耦合成串聯組態。結果,電池組需要至少各個電池的長度、兩倍各個電池的厚度、及三倍各個電池的寬度之可攜式電子裝置的空間。而且,電池組無法利用為電池組所保留之矩形空間的外面之可攜式電子裝置中的自由空間。
因此,藉由有關含鋰聚合物電池的電池組之封裝效能、容量、形式因子、成本、設計、及/或製造的改良,可幫助可攜式電子裝置的使用。
所揭示的實施例提供與可攜式電子裝置一起使用之電池組。電池組包括電耦合成並聯組態之具有不同容量的第一組電池。第一組電池內的電池亦可具有不同厚度及/或尺寸。第一組電池係配置在電池組內,以幫助有效使用可攜式電子裝置內的空間。例如,第一組電池可被配置以容納組件在可攜式電子裝置中。
在一些實施例中,電池組亦包括電耦合成並聯組態之具有不同容量的第二組電池。若第一組電池和第二組電池具有實質上相同的容量,則第一組電池和第二組電池可電耦合成串聯組態。
在一些實施例中,將第一組電池堆疊、並排置放、或上下置放在電池組內。
在一些實施例中,第一組電池的一或多個對應於鋰聚合物電池。
在一些實施例中,第一組電池的一或多個包括:
(i)含捲繞在一起的層之凍膠捲(jelly roll),包括具有活性敷層之陰極、隔板、和具有活性敷層之陽極;以及
(ii)囊袋,圍住凍膠捲。
描述下面說明以使精於本技藝之人士能夠製造和使用實施例,及以特定應用及其需要的背景來提供。精於本技藝之人士很容易明白所揭示的實施例之各種修改,及只要不違背本揭示的精神和範疇,此處所定義的一般原理可應用到其他實施例和應用。如此,本發明並不侷限於所示之實施例,而是欲符合與此處所揭示之原理和特徵一致的最廣泛範疇。
此詳細說明所說明之資料結構和碼典型上儲存在可以是任何裝置的電腦可讀取儲存媒體,或者可儲存由電腦系統所使用的碼及/或資料之媒體。電腦可讀取儲存媒體包括但並不侷限於揮發性記憶體、非揮發性記憶體、諸如硬碟機、磁帶、CD(小型碟)、DVD(數位多用途碟或數位視頻碟)等磁性和光學儲存裝置、或現在已知或往後將發展的能夠儲存碼及/或資料之其他媒體。
詳細說明段落中所說明之方法和處理可被體現作碼及/或資料,其可如上述儲存在電腦可讀取儲存媒體中。當電腦系統讀取和執行儲存在電腦可讀取儲存媒體上之碼及/或資料時,電腦系統執行被體現作碼及/或資料且儲存在電腦可讀取儲存媒體內之方法和處理。
而且,此處所說明之方法和處理可包括在硬體模組或設備中。這些模組或設備可包括但並不侷限於應用特定積體電路(ASIC)晶片、現場可程式閘陣列(FPGA)、在特別時間執行特別軟體模組或一段碼之專屬或共享處理器、及/或現在已知或往後將發展之其他可程式邏輯裝置。當致動硬體模組或設備時,它們執行包括在它們裡面的方法和處理。
實施例提供具有不同容量、厚度、及/或尺寸的多種電池之電池組。電池亦可被配置以幫助有效利用可攜式電子裝置中的空間。例如,將電池堆疊、並排置放、及/或上下置放,以容納組件在可攜式電子裝置、膝上型電腦、及/或平板電腦中。
此外,電池可電耦合成串聯及/或並聯組態。尤其是,電池組可包括電耦合成並聯組態之具有不同容量的第一組電池。電池組亦可包括電耦合成並聯組態之具有不同容量的第二組電池。若第一組電池和第二組電池具有實質上相同的容量,則第一組電池和第二組電池可電耦合成串聯組態。
圖1為根據實施例之電池組100。電池組100可供應電力給可攜式電子裝置,諸如膝上型電腦、行動電話、平板電腦、個人數位助理(PDA)、可攜式媒體播放器、數位相機、及/或其他類型的電池供電型電子裝置等。
如圖1所示,電池組100包括一些電池102-112。電池102-112可對應於可充電(如、二次)電池,諸如鎳鎘(Ni-Cd)電池、鎳金屬氫化物(Ni-MH)電池、鋰離子電池、及/或鋰聚合物電池等。例如,一或多個電池102-112可對應於鋰聚合物電池,其各個包括捲繞在一起的層之凍膠捲(如、具有活性敷層之陰極、隔板、和具有活性敷層之陽極)以及封住凍膠捲之撓性囊袋。下面參考圖3更詳細說明鋰聚合物電池。
在一或多個實施例中,電池102-112具有不同容量、厚度、及/或尺寸。例如,電池102-104可各具有3.2 Ah的容量,電池106-108可各具有1.5 Ah的容量,及電池110-112可各具有1.7 Ah的容量。同樣地,電池102-104可比電池106-112更長、更厚、及/或更寬,及電池106-108可比電池110-112更長、更厚、及/或更寬。
電池102-112亦可電耦合成串聯及/或並聯組態。尤其是,具有不同容量的第一組電池102、106、及110可電耦合成並聯組態,及具有不同容量的第二組電池104、108、及112亦可電耦合成並聯組態。因為第一組電池和第二組電池具有實質上相同的總容量,所以第一和第二組電池可電耦合成串聯組態。換言之,電池102-112可電耦合成兩個串聯、三個並聯(2s3p)的組態。
尤其是,電池102-112的選擇、電組態、及/或配置可依據可攜式電子裝置的實體及/或電需求。首先,電池102-112可被選擇用於電池組100及/或電耦合在電池組100內,以符合可攜式電子裝置中之組件(如,印刷電路板(PCB)、處理器、記憶體、儲存體、顯示器、光學驅動器等等)的電需求(如,電壓、電容等等)。例如,電池106可並聯電耦合到電池110,及電池108可並聯電耦合到電池112,以給予所電耦合的電池106及110和電池108及112與電池102及電池104相同的容量(如,3.2 Ah)。電池102、電池104、電池106及110,和電池108及112然後可串聯耦合,以增加電池組100的電壓。
沿著同一線路,電池102-112可被選擇用於電池組100及/或配置在電池組100內,以幫助有效利用可攜式電子裝置中的空間。例如,電池102-112可被選擇用於電池組100及堆疊、並排置放、及/或上下置放在電池組110內,以容納組件在行動電話、膝上型電腦、及/或平板電腦中。電池組100如此可包括最大化可攜式電子裝置內的自由空間之使用的不對稱設計。接著,電池組100可提供比含具有相同容量、尺寸、及/或厚度的電池之電池組更大的容量、封裝效能、及/或電壓。下面參考圖2-3更詳細討論含變化的大小及/或尺寸之電池的電池組。
圖2為根據實施例之電池組的橫剖面圖。電池組包括不同厚度及/或大小的三個電池202-206。如圖2所示,電池202最薄,電池204為中間厚度、及電池206最厚。此外,可依據允許電池組能夠填滿可攜式電子裝置內的自由空間之不對稱設計而將電池202-206配置在電池組中。例如,電池202-206可定位在電池組內,以佔用行動電話、膝上型電腦、可攜式媒體播放器、數位相機、及/或PDA內的空間之彎曲區域。
圖3為根據實施例之電池300。電池300對應於被用於供應可攜式電子裝置電力之鋰聚合物電池。電池300包括含捲繞在一起的一些層之凍膠捲302,其包括具有活性敷層之陰極、隔板、和具有活性敷層之陽極。尤其是,凍膠捲302可包括以一條隔板材料分開(如、導電聚合物電解液)之一條陰極材料(如,塗敷有鋰化合物之鋁箔)和一條陰極材料(如,塗敷有碳之銅箔)。陰極、陽極、和隔板層接著可捲繞在心軸上以形成螺旋形捲繞結構。凍膠捲是技藝中眾所皆知的,及將不再進一步說明。
在組裝電池300期間,凍膠捲302封裝在撓性囊袋中,其係藉由沿著折疊線312折疊撓性薄片所形成。例如,撓性薄片係可由具有聚合物膜的鋁所製成,諸如聚丙烯等。在折疊撓性薄片之後,可例如藉由沿著側邊密封310和沿著平臺密封308施加熱來密封撓性薄片。
凍膠捲302亦包括耦合到陰極和陽極之一組導電翼片306。導電翼片306可延伸過囊袋中的密封(例如,使用密封帶304所形成),以提供端子給電池300。導電翼片306然後可用於電耦合電池300與一或多個其他電池以形成電池組,諸如圖1的電池組100等。
例如,電池組300可屬於電耦合成並聯組態之具有不同容量的電池組中之第一組電池。電池組亦可包括電耦合成並聯組態之具有不同容量的第二組電池。若第一組電池和第二組電池具有實質上相同的容量,則第一組電池可以串聯組態電耦合到第二組電池。結果,導電翼片306使電池300能夠用於包含電耦合成並聯及/或串聯和並聯組態之不同容量電池的電池組。
圖4為根據實施例之提供電源的處理之流程圖。在一或多個實施例中,可省略、重複、及/或以不同順序執行一或多個步驟。因此,圖4所示之特定步驟排列不應被闡釋作限制實施例的範圍。
最初,將具有不同容量的第一組電池配置在電池組內,以幫助可攜式電子裝置內的空間使用(操作402)。可針對使電池能夠適當供應電力給及/或容納組件在可攜式電子裝置中之實體(如,尺寸、厚度等等)及/或電(如,電容、電壓等等)特性來選擇電池。電池可對應於鋰聚合物電池及/或其他類型的可充電電池。接著,第一組電池電耦合成並聯組態(操作404)。並聯組態可增加電池組的容量和冗餘二者。
具有不同容量之第二組電池亦配置在電池組內(操作406)及電耦合成並聯組態(操作408)。由於具有第一組電池,所以第二組電池可被選擇、電耦合、及/或配置在電池組內,以符合可攜式電子裝置中的組件之電和實體需求。
最後,以串聯組態將第一組電池連接到第二組電池(操作410)。兩組電池的串聯連接可增加電池組的電壓。而且,若第一和第二組電池具有實質上相同的容量,則第一和第二組電池可以串聯電耦合。
上述可充電電池組通常可被用於任何類型的電子裝置。例如,圖5圖解可攜式電子裝置500,其具有處理器502、記憶體504、及顯示器508,它們全都以電池506供給電力。可攜式電子裝置500可對應於膝上型電腦、平板電腦、行動電話、PDA、可攜式媒體播放器、數位相機、及/或其他類型的電池供電電子裝置。電池506可對應於包括一或多個可充電電池之電池組。尤其是,電池組可包括電耦合成並聯組態之具有不同容量的第一組電池。電池組亦可包括電耦合成並聯組態之具有不同容量的第二組電池。若第一組和第二組電池具有實質上相同的容量,則第一組電池和第二組電池可電耦合成串聯組態。
僅為了圖解和說明目的來描述上述各種實施例的說明。它們並不是耗盡性的或者打算將本發明侷限於所揭示的形式。因此,許多修改和變化對精於本技藝之人士是明顯的。此外,並不打算用上述揭示限制本發明。
