201212470 六、發明說明： 【發明所屬之技術領域】 本發明關於一播a ·*·々 之電瓶電池串的電瓶 開、種具有多數獨立 以及 種具有這種電瓶的電動汽車 【先前技術】 車輛’在將來不論是在位置固定方式的應用或在 =例如油電雙用車及電動車都更多使用到電池系統。為 了使對各種用途的電壓的要求以及可用的功率都要能滿 足’故將多數電瓶電池（Battene議，英切eryeeu)串聯。 由於由這種電瓶提供的電流須流經所有電瓶電池，且一電 瓶電池只能通過有限電流，故往往將附加的電瓶電池並 聯’以將最大電流提高，這點可藉在一電瓶電池殼體内設 多數電池繞組或藉著外接電瓶電池而達成。但在此有—問 題：由於電池容量和電池電壓不是確地㈣，在並聯的電 瓶電池間會造成補償電流。 在圖1中顯示外接一個一般的電驅動系統的原理圖， 例如由於電動車及油電雙用車或在位置固定的用途，例如 在風力發電設備的轉子葉片的調整。一電瓶（1〇)接到一直流 電壓中間回路，它利用一電容器（11)緩衝。有一脈波交流整 流器（12)，它經由各二個可切換的半導體閥及二個二極體在 二個輸出端提供互相有相位偏移的正弦波電壓以操作—電 驅動馬達（13)。此電容器（Π)的電容須夠大，以將直流電壓 中間回路中的電壓穩定化為一時段，在此時段中，該可切 201212470 換的半導體閥導通。在一 隹實際的應用，如電動車，則造成 毫法拉第範圍的高霜 _ 。電办’由於直流電壓中間回路的電壓一 般很尚’因此如此大的雷六士'士/ 穴的電今成本很高，且空間需求大。 【發明内容】 本發明的目的在提供—種具有多數電瓶電池串列 的電池，這些電航電池串列各含有多數電瓶電池’串聯到 一第一極及一第二極之間。 本發明的電瓶有—優 復點·電瓶的總容量劃分成互相獨 立的電瓶電池串（BattpHpi7e11 t lstrang)，如此在電瓶電池與電 瓶電池串之間不會再有補僧银、$ 、、 有補仞電>;,L。如果這種電瓶接到一脈 波交流整流器（它有對廊齡 心數目之成對的輸入端，正如電瓶具 有電瓶< 電池串）則镑；/ a , ' ' 電益（匕們各接到該脈波交流整流 器的成對輸人端）的所需容量可減少。對於特定的用途及度 1設計。這些緩衝電容器在某些狀況可完全省却。 4電瓶且正好包含三個電瓶電池串。這種電瓶特別適 合一些電馬達的驅動5| “古此φ昆，去 動益些電馬達一般需要三個相位偏移 的正弦波電壓操作）。 該多數電瓶電池串的各第一極可與各—第一電瓶端子 ，導電連#纟第一電瓶端子可使瓶接到—脈波交流整流 器（它具有對應多數的輸入端。 在本發明-實施例，電瓶電池串的第二極可互相連接 綱。因此互相連接的第二極構成一較佳以立，舉例而 言它可與汽車的接地線連接’為此電瓶電池串的第二極可 201212470 與一第二電瓶端子連接成 瓶電池串的各m導電。如^此方式，該多數電 該多數電瓶雷、“ τ與各第二電瓶端子連接成導電。 ^電池串㈣—極可為電瓶的正㉟，而該多數電 开/的第二極可為電瓶的負極。 X電瓶電池宜為鋰離子電瓶電池。鋰離子電瓶電池的 為有高電池電壓以及每單位體積有特高的電容量。 此電瓶可有一電池殼體，其中設有該多數電瓶電池串。 本心月的第一標的為一種汽車，該汽車具有一種電 驅動馬達以驅動吐、、与击，# β > , , 助此/飞車並具有一個依本發明第一標的之 電瓶，該電瓶與該電驅動馬達連接。 本發明的實施例利用圖式和以下的說明詳細敍述，其 中相同的圖號表示相同的元件或功能相同的元件。 【實施方式】 圖1顯示本發明一第一實施例。此第一實施例有三個 電瓶電池串（21-1)(21-2)及（21-3)，它們各有相同數目之串聯 的電瓶電池。由於沒有一個電瓶電池串（21 _1)(2 ^2)(2^3) 有串聯的電瓶電池’儘管電瓶的總容量可很大（它相當於電 瓶電池之個別串聯電路的三倍），並不會在串聯的電瓶電池 之間造成補償電流。電瓶（20)的各電瓶電地串 (21-1)(2 卜2)(21-3)各有一正電瓶端子（22-1)(22-2)(22-3)及 一負電瓶端子（23-1)(23-2)(23-3)。 圖3顯示本發明之一第二實施例’電瓶（30)大致和電瓶 (2〇)相當且一如電瓶（20)有三個電瓶電池串 201212470 (31-1)(31-2)(31-3)。各電瓶電池串各有正電瓶端子 (32-1)(32-2)(32-3)，在本發明此第二實施例，電瓶電池串 (3 1-1 )(3 1-2)(3 1-3)的負極互相連接成導電，因此也只設一負 電瓶端子（33)。 圖4顯示一電驅動系統，它具有一本發明的電瓶（2〇)， 一脈波交流整流器（42)直接（換言之，沒有一個或數個電容 器接到其輸入端）與電瓶（20)的三對電瓶端子連接。對於各 切換路徑（它具有各二個半導體閥及二個二極體）有一對本 身的輸入端，它們與該電瓶（2〇)之三對電瓶端子的各一對連 接。因此可省却直流電壓中間回路或設有三個個別的直流 電壓中間回路。由於從電瓶之脈波整流器（4 2)的個別切換路 徑及直流電壓中間回路取出的功率較小，因此可利用較小 的電容器將直流電壓中間回路作緩衝，或者——如圖4所 示--省却緩衝作用。脈波交流整流器（42)的切換路徑在輸 出端係與電驅動馬達（13)的三個相位端子連接。 【圖式簡單說明】 圖1係依先前技術的一電驅動系統； 圖2係本發明一第—實施例； 圖3係本發明一第一實施例； 圖4係電驅動系統’具有-本發明的電瓶。 【主要元件符號說明】 (1〇) 電瓶 201212470 (11) 電 容 器 (12) 脈 波 交流 整流器 (13) 驅 動 馬達 (20) 電 瓶 (21-1) 電 瓶 電池 串 (21-2) 電 瓶 電池 串 (21-3) 電 瓶 電池 串 (22-1) 正 電 瓶端 子 (22-2) 正 電 瓶端 子 (22-3) 正 電 瓶端 子 (23-1) 負 電 瓶端 子 (23-2) 負 電 瓶端 子 (23-3) 負 電 瓶端 子 (31-1) 電 瓶 電池 串 (31-2) 電 瓶 電池 串 (31-3) 電 瓶 電池 串 (32-1) 正 電 瓶端 子 (32-2) 正 電 瓶端 子 (32-3) 正 電 瓶端 子 (33) 負 電 瓶端 子 (42) 脈 波 交流 整流器
