具裝置電力順應性的無線充電系統
本申請案係有關於2009年元月六日提申之發明名稱為”Metered Delivery of Wireless Power”的美國專利申請案第12/349355號，其目前為美國專利第＿＿＿號，其在本文中併入以供參考。
本發明有關無線電力系統，更多具體地係有關能夠同時供電多重裝置的這類系統。
無線供電或充電系統係為人所熟知及廣泛使用的。這類的系統典型地包含一初級電源供應及一或更多的二級裝置。當二級裝置靠近初級線圈時，初級線圈感應地供電至該二級裝置。
雖然這類系統係為人所熟知，但數個潛在問題仍伴隨著該系統。
首先，每一初級供應係典型地為了一具體應用而加以設計，其取決於從電力供應所汲取的能量。當二級裝置的電力需求係大於初級供應的功率容量(power capacity)時，發生問題。該二級裝置可能停機，或者該二級裝置可能以不適合裝置之該可取得的、降低的電力層次，企圖充電。典型地，每一者發生時都未回饋或警告使用者。結果，該裝置可能不適當地充電或一點也沒充電。
其次，多重的二級裝置典型地需要多重的電源供應，即一對每一裝置。這能夠造成大量的電源供應，其係昂貴的，及難以儲存、使用及配合該二級裝置。
前述的間題在本發明中加以克服，其中在該無線電源供應之內的多個元件，彼此通訊電力需求及功率容量，以致於電力順應性得加以管理。更加具體地，每一二級裝置係能夠與無線電源供應加以通訊， 而提供每一裝置的電力需求之指示；及相對地，該電源供應能夠與每一二級裝置加以通訊而提供該供應之功率容量的指示。
結果，一無線電源控制能夠解決在電源供應及二級單元之間的電力分佈需求。如果二級裝置的電力需求超過系統容量，則該控制能夠提出警告。該控制也能夠使充電在降低的電力層次下進行。如果多數個二級裝置進入該充電系統，該控制能夠分配電力於該裝置之間。
結果，本發明提供一無線充電系統內的增強的電力順應性。該系統提供介於功率容量及電力需求間的失配指示，也提供多重裝置之間的電力分佈而能夠使用單一電源供應來充電多重裝置。
本發明這些及其他的目的、優點及特徵，在參照目前實施例之描述及圖式之下，將會更完全地受到瞭解及理解。
一習知技術的充電系統10係圖解於第一圖中，其包含一無線電源供應(WPS)12及一可攜式二級裝置14。無線電源供應12接著包含一整流器16、一DC/DC轉換器18、一反相器20、一電容22、一感應線圈24及一控制26。可攜式二級裝置14包含一二級線圈30、一電容32、一整流器34、一DC/DC轉換器36及一負載38。當二級線圈30係接近該初級線圈24時，及當該初級線圈被供電時，一感應鏈結受到建立；及在該二級線圈內感應出一電壓。迄今所談論之無線充電系統10係為人所熟知的，其結構及功能無需進一步詳述。
第一圖所示之類的供電系統典型地需要使用者瞭解及記住何者裝置及何者電源供應係一同工作。具有不同功率容量而配備相同連接器的兩個不同的電源供應，能夠物理地連接到相同的裝置。然而，在一裝置上使用不正確的電源供應，能夠潛在地造成失效或不當操作。使用只能夠從某些型式的失敗模式得知這類失效或者不當操作，例如裝置的過度供電或無法充電裝置。
本發明能夠使供電系統及二級裝置彼此進行通訊，及其係可配置的及能夠管理多種系統元件間的電力順應性。
在過去，供電系統係依賴使用者知悉及瞭解何種裝置及電源供應一同工作。具有相同連接器的兩個不同的電源供應能夠輕易地連接至相同裝置。這樣能夠潛在地造成失效或者不當操作。使用者只能從失效模式知悉這類失效。
藉由允許供電系統進行通訊及成為可配置的，本發明試圖解決上述問題。裝置能與電源供應進行通訊及提供與裝置的所有通訊給予使用者。
電源供應順應性
電源供應及無線電源供應兩者分別通知其容量及能夠解決電力分佈需求。來自遠方電源供應或內部電源供應的資訊，係傳送至無線電源控制。該系統係加以設計而藉由初級線圈對二級線圈之通訊來警告使用者，其為該裝置需要比無線電源供應及主電源供應所能供應者還多的電力。
初級線圈對二級線圈之通訊
初級線圈對二級線圈之通訊的方式有許多種，例如那些揭示在本申請案中者。某些方法牽涉到小改變-約1%~2%的電力來調配一簡單的訊號。其他的方法在短期內完全地停止振盪，以傳送基本訊號。這些基本通訊能夠造成以下特徵：充電授權的主要要求-排序
適當充電的驗證-驗證交換
本裝置可得的電力不足-小於所需要之可得的瓦特
充電次序的通訊-充電之後-2nd 在線要求充電
裝置的配置-無聲、振動、無線電關閉
不順應標準
較小的電源供應對多重裝置進行充電
在另一例子中，本發明能夠令一個五瓦的電源供應依序地對數個五瓦的裝置進行充電。每一裝置傳送充電比(充電電力vs.經時消耗的電力)及充電要求(目前的容量)。使用這些來自每一裝置的比值，充電能夠加以分割及排序，在充電非常受到限制之下，允許許多裝置具有合適的電力。本途徑相似於依照需要而將充電電纜通過桌子周圍，但只是無線地加以進行。一個示範性的使用為配備數個膝上型電腦的會議桌。實際上一次只有一個膝上型電腦需要進行充電。該排序去除了以最大功率轉換所有裝置瓦特數的能力，及降低製造成本。
使用供電管理介面的無線供電增強
無線電源供應包含該電力管理單元。在習知技術中，該系統包含背光、無線電、硬驅動機、GSM脈衝、及被開啟及閉關的相似裝置，該電源供應係加以設計而對這些系統作出反應及提供穩定的電源。本發明利用來自一系統之知識，即由系統觀點，在電力需要加以開啟與關閉時，藉由預測一基於電力衝擊的改變百分比而有效地管理控制。該知識允許電源供應直接對需求進行反應。在習知技術的系統中，一比例-積分-微分(PID)控制迴路，因為減去多重的迴路通過而節省時間；及該系統能夠更加快速地反應。藉由連接二級裝置的電力管理單元(PMU)及指派每一負載的錯誤值，負載中改變的總合係能夠輕易地從電力管理單元傳送到二級無線供電控制，然後通知無線電源供應以改良迴路反應時間。
總控制描述
基於錯誤的控制模式允許介於二級控制介面(SCI)及初級控制介面(PCI)之間的控制迴路構形。PCI對來自SCI的控制錯誤回饋封包進行反應，決定抵達操作點所需要之調整。這提供明顯的設計自由度。多種型式的控制能夠在二級側加以實施。演算法的例子包含恆定電 流、恆定電壓或恆定供電。在第一．五圖中的狀態圖描述用於本控制方法中的演算法。
預測的PID控制
PID系統誤差及計時，在無線供電初級控制及二級接收器及供電管理系統之間，能夠加以協調。表一顯示這種計時及供電是如何能夠加以使用而形成將要受到需求的額外所需電力及該用於協調這些系統的最小計時。任意的電流及計時係作為範例。這些值係預先測定而作為最佳全體系統性能及儲存在二級系統中以便與供電管理系統進行協調。
接著，使用該測量值加上新控制值總合(如表一之總合)，計算線圈_電流_設定點。如此，藉由限制行程控制(course control)所需的迴路數量，允許系統具有更快的控制。藉由限制PID反應所需時間(因為其允許預測及反應輸入)，該粗糙的控制允許較少的漣波。
PID控制
控制演算法使用一PID控制法。PID控制演算法係未連續地進行，因為其更加可能造成毁壞的資料通訊。加以替換的是，PID演算法企圖改變初級線圈電流成為一介於重複控制回饋封包(CFP)之間的經計算的操作點。
SCI較佳地並未在PID演算法活化期間企圖通訊。控制誤差回饋封包之間的最小計時係在裝置ID酬載之內加以界定。
一通用的PID控制器係顯示在表三。該數學運算係在PCI之內再次發生。
輸出
新線圈電流計算
PID控制迴路所用的PCI線圈電流訊號，係由A/D及一計算出之移動均數加以示範。該演算法在每一次接收到來自SCI之非零控制誤差回饋封包時，由以下公式計算一新的目標PCI線圈電流。
“回饋誤差”係定義為SCI所傳輸之控制誤差封包的酬載：回饋誤差=反應誤差+預測誤差如果回饋誤差=零，PID控制迴路不運作，因為無需調整操作點。
“先前設定點”係定義為PID迴路初始運作之最近的穩定化初級線圈電流，或者是在調整之後的最後的穩定化初級線圈電流。
最大誤差計數係定義為可由SCI加以報導之最大誤差。在本實施例中，其範圍介於+/-27。
線圈電流係在PID活化之前回到穩定狀態，以致於誤差的計算係正確的及減少所需的頻率調整次數。在接收到來自SCI之資料封包(由”PID延遲時間”參數所決定)之後，該演算法靜待線圈電流成為穩定 化。正確的延遲期間係基於資料通訊之後PCI線圈電流回到穩定狀態所需之最大時間及回饋訊號至初級A/D之過濾延遲(filter delay)。
以下的算式係用於取得新的操作點：計算誤差=先前設定點-線圈電流設定點
正比計算
演算法的正比期間係由以下等式加以計算：P正比期間=計算誤差*k (3)
積分計算
演算法的積分期間係由以下等式加以計算： 其中積分更新間隔係基於所要之積分比的增益調整。使用積分上限及積分下限參數加以控制終結(wind-up)。
微分計算
演算法的微分期間係由以下等式加以計算： 其中微分更新間隔係基於所要的差異比例之增益調整。
總PID計算
總PID計算係為正比、積分，與微分期間的總和。
PID輸出=正比期間+積分期間+微分期間 (6)
使用積分上限及積分下限參數加以控制最大輸出。
更新操作點計算
最後頻率調整係由以下等式加以計算：
“增益校正因子”將共振曲線分割成為片狀的線性函數。
“PID規模因子”係用於幫助PID計算中的整數計算。
“PID延遲時間”過期之後，在”PID活化時間”之期間，PID迴路活躍地利用上述的等式，企圖將PCI線圈電流引入新的目標設定點。
最後，PID控制係在”PID設定時間”之期間加以抑制，以致於一正確的PCI線圈電流的讀數，係藉由初級線圈加以紀錄，及一正確的電壓及電流讀數係藉由SCI。
基於控制迴路計時的誤差
在”PID活化時間”期間之初級線圈頻率的調整之間的最大分派時間，係為基於控制迴路計時的誤差，其為0.4毫秒(ms)。這個控制迴路係與電力管理系統及控制計時一同協調，以便供電至系統。誤差及通訊係協同電力管理系統及計時控制而彼此溝通。計時係加以控制，並藉由初級無線電源供應，利用來自該表之電力及控制延遲值而加以協調。初級及二級系統，基於分享自已經處理之電力變數增量總合之最大值，協調該計時。
本實施例係使用誤差控制的一個方法，及一般精於本項技藝的人士將會承認該所述的方法學能夠使用於許多方法中而協調無線供電控制及裝置電力管理。
第二圖顯示一系統，其中電源供應、無線電源供應及二級裝置均使電力調合至裝置。電纜218在電源供應212及無線電源供應214之間提供一硬金屬線連接。無線電源供應214及無線電源裝置216係依照習知技術而加以感應耦合。
DC電源供應212的瓦特值係由一類比電壓、一數位訊號、或頻率協調而傳訊至無線電源供應214。無線電源供應214接收來自電源供應212的功率容量資訊，及來自二級裝置216的裝置電力需求。
二級裝置216包含一二級裝置控制224及標示226。二級裝置216接收來自無線電源供應214的系統功率容量資訊，及能夠充電或指出 不相容性以回應該資訊。
可能的是，電源供應212的電壓及/或功率容量係較低於無線電源供應214者。在這個例子中，無線電源控制220對其自身加以構形，以致於其能夠只供應來自該電源供應212的電力。
也可能的是，電源供應214的電壓及/或功率容量係小於二級裝置216所需的電壓或電力。在這個例子中，誤差訊號係顯示在標示222及/或226。此外，二級裝置控制224能夠作成一個決定，其關於是否全部充電或者以可得的電力層次加以充電。為回應裝置控制224的決定，無線電力控制220能夠自身構形而完全不提供電力或提供二級裝置控制224所需的電力層次。
因此，第二圖的系統210能夠1)使二級裝置216及無線電源供應214之間的電力順應；2)使二級裝置216及無線電源供應214之間進行通訊；3)使較少的無線電源供應用於充電多重裝置；及4)使用裝置的PMU。
第三圖顯示電力供應如何使用第三條金屬線將可得自於電源供應312的電力傳訊至無線電源供應314。這個構形使用一資料訊號以傳訊該電力資料至無線電源供應314。第三金屬線319直接連接電源供應312之電力控制迴路328至無線電源供應314的驅動控制324。
第四圖顯示第三金屬線419，其傳訊類比資料，其代表可得自該電源供應412的電力。因此，第四圖的系統410係第三圖所示之系統310的類比實施。如先前實施例中，瓦特數係藉由類比電壓、資料訊號或頻率而加以傳輸。電源供應412將功率容量傳訊至無線電源供應414。
圖解在第四．五圖中的系統410顯示一些通訊，其用於將來自電源供應412及無線電源供應414之資訊，傳訊至二級裝置(未示)。這些通訊係關於使用遠方的電源供應412、連接器419及一用於調整電力(在 預期水準之1%~2%之內)的合適的可得電力。電源供應412改變幹線電壓430，且無線電源供應414調整初級訊號432以回應提供通訊至二級裝置。結果，初級側通訊經由通訊或一控制電壓，而從命令訊號調整成為一造成此變異之可編程的電源供應。
第四．六圖顯示一無線電源供應414a，其中電源供應係植入該無線電源供應中，及使用初級幹線電壓調整作為簡單命令。該電力係基於命令訊號而在1~2%之間變動。該變動可為正的或負的。
第四．七顯示一無線電源供應414b，其包含一初級線圈分流434。該分流係用於改變初級線圈上的電壓以通訊至二級裝置。
第四．八圖顯示一無線電源供應414a，其提供一調頻(FM)版本的通訊，其使用以頻率為基礎的控制器。命令訊號436、初級驅動訊號438、已調變的初級驅動訊號440，全部都長期地顯示成一直線，以說明在通訊期間的訊號變異。示範性的ASCII碼442也加以顯示。使用所示的實施例，訊號查詢表可提供多重二級裝置的管理，如膝上型電腦。此外，充電可加以排序而”同時地”充電多重裝置。
第四．八五圖、第四．八六圖及第四．八七圖顯示額外的實施例，其特別地有關於無線供電與消費者之通訊。這些實施例也使無線供電可能地更加有用，因為一個五瓦特的初級線圈能夠充電一個電腦，雖然這需要加長的時間來進行。此外，電腦在充電期間可加以關閉以便快速充電。較佳地，在知悉能力及需求並因而對這些加以通訊及談判之下，每一個二級裝置內的電力控制系統依照需求而關閉系統。此外，這個資訊直接通訊至使用者而無需額外的信號或解釋，使得一個簡單的”盲目”界面(“blind”interface)能夠提供資訊給予使用者而適當地瞭解功能限制。也顯示在第四．八七圖中的一個簡單的標誌，能夠代表收集自無線供電系統之額外資訊的實質數量。
此外，第四．八五圖也顯示一個系統，其需要額外的電流以便取 得非常低的儲備電池。藉由暫停其他充電而允許一低的電池或者滿足額外的系統要求，該系統能夠增加所需要的電力。這個動態負載管理系統使用無線供電及通訊。
第四．九圖顯示一能量調制通訊方法，其允許初級控制器停止驅動訊號一段經指示的時間以便傳送基礎資訊。在二級線圈傳送一辨識串至無線電源供應之後，藉由電力傳輸脈衝使初級側通訊受到調制。示範性的脈衝係顯示在圖式之左下角。
第五圖顯示一系統510，其中該電力係受到無線電源供應514加以調和。系統510允許較少的電源供應元件及能力，以便依照所示進行驅動及加以利用。這些系統能夠自我構形，及通訊至裝置容量及有效性以進行充電。電源供應的瓦特數W係藉由電源供應控制器513，經由類比電壓、資料訊號或調頻，加以通訊至無線電源供應514。無線電源供應514接收到來自電源供應控制器513之DC功率容量，及來自二級裝置控制器524之裝置電力需求。二級裝置控制器524接收到來自無線供電控制520之系統功率容量資訊。二級裝置控制器能夠充電及/或在裝置電力需求超高系統容量時指示不相容性。預設的電力值能夠硬植入程式(hard programmed)或儲存在電源供應512、無線電源供應514、或裝置516之非依電性記憶體系統中。這些數值能夠(例如)代表工廠測試限制，及這個資訊能夠令系統及使用者瞭解到系統的容量。
第六圖解說一電力分配系統610，其中利用裝置安放在初級線圈附近以便作為優先的充電次序。如果兩個裝置係安置在一個容量不足以同時充電該兩者的墊板(pad)上，則一個二級裝置將會充電。當電力可用於進行下一單元時，其也會發動充電。該系統管理該系統限制之內的電力分配。
充電的排序係依賴於安放在無線電源供應(WPS)614上之裝置的 次序。充電容量係可用的時候，如第一或下一個裝置已經充電時，可用的額外容量能夠用於充電第二及/或下一個裝置。
如果該無線供電控制的容量C係小於二級裝置X的組合需求，則在二級裝置上提供一個警告，及/或由WPS614提供警告。在這樣的情況之下，第一裝置係受到充電，及下一個裝置只有在容量變成可用之時才接收電力。可更換的是，該演算法可加以修改，將一或更多二級裝置616之電池的狀態也納入計算。容量資訊或電池狀態也可作為優先充電指標。例如，如果電池係處於較低的或嚴苛的狀態之下，則該狀態能夠影響優先性。這項特徵可為無線電源供應之內的使用者可選用的。
第七圖顯示另一修正的系統，其中經由無線電源供應714分配的電力至少部份地受到無線供電控制720的管理以便反應每一個二級裝置716a~c的電力比。例如，這個實施例藉由瞭解到充電狀態，及藉由輪流充電(基於充電比對放電)，能夠令單一的膝上型電腦充電器對許多膝上型電腦進行充電。例如，如果三個膝上型電腦具有2.5的充電比，每一者能加以充電15分鐘及取得45分鐘的使用。這個成就使得三個單元的一個15分鐘周期消耗全部的電力，及以較低成本的方式解決問題(相較於裝置特定充電器)。
加以計算充電比如何地降低充電時間。較低的電池取得優先次序及需要較長的充電時間以避免長周期。最差充電狀態的電池首先起動充電。在本實施例所討論的特定充電比只是用於說明而已。現有的二級裝置716能夠監視個別的充電周期。
第八圖顯示一類比輸出，其用於選擇電源供應的瓦特數以便實施類比控制方法。第四圖中所示的控制金屬線419承載該類比訊號，其係由第八圖中所示的電阻構形加以選擇。電壓係加以分級製表，及該表係用於指示電源供應的瓦特數容量，其係基於在金屬線419上被傳 送到無線電源供應424之類比選擇電壓。較佳的方法係為數位通訊訊號，以便較佳地對限制進行解析及取得容量資訊。
第九圖顯示介於無線電源供應214及裝置216之間的資料次序。在無線電源供應之內，系統進行供電901及讀取二級裝置所要求的瓦特數。如果裝置係呈現902，則該裝置識別係讀為903。如果裝置未呈現902，則該系統持續監視充電器904。如果裝置識別標誌已被偵測為903，則裝置標誌係傳送905至該二級裝置。如果裝置標誌未受到偵測，則該系統進入待機模式906直到裝置瓦特數係大於或等於負載時為止；及該系系指出該負載係為不相容的。
在二級裝置之內，如果該裝置係可相容的907，則該二級裝置係加以供電及/或充電908。如果該裝置係不相容的，則作出一個決定909，其係相關於該裝置是否可在較低比率下進行充電。如果該裝置無法在較低比率下進行充電，則該裝置及/或WPS指出不相容性910。如果該裝置係能夠在較低比率下充電，則該裝置係以該較低的速率加以供電908。
第十圖顯示一基礎回饋機制，其包含接觸及/或聲音。在使用者駕駛之時及/或該裝置係安置於充電之時，這個實施例係吾人想要的。這個方法允許與使用者進行較少的互動，及對合適及不合適的容量作出正回饋。
如第十圖所示，觸覺回饋誤差(haptic feedback error)的實施例係三個振動，其中三個表動之每一者之間具有延遲。指出可接受條件之觸覺振動係單一振動。當然其他的數字及/或振動樣式也可加以使用。這些樣式可能相異於鈴聲、SMS、或電子信件標誌。目前行動電話中所用的振動馬達係能夠輕易地加以利用作為這類回饋裝置，其能夠指出相容性或不相容性而無需目視這些標誌。在汽車或駕駛環境之中，這樣是特別有利的。
如第十圖所示，回饋係可由聲音加以提供，如果嗶嗶聲及/或音調，其具有特定的強度(音量)、頻率(節奏)、間隔(樣式)及音色(音亮)。頻率、音量、樣式及/或音色在二級裝置更加接近初級線圈時係能夠加以改變。示範性的誤差訊號係能夠在低及高節奏之間加以更換。使用觸覺回饋之下，可接受的匹配之標誌可由單一的嗶嗶聲加以提供，同時不相容性的標誌係可由多重的嗶嗶聲(如三個)加以指示。如果在二級裝置及/或WPS上提供LEDs或其他視覺標誌，則一個可能的相容性指示係連續地以視覺標誌照明，同時不相容性的指示係由周期性的或閃動的視覺標誌作出訊號。其他的指示包含顯示出一或多種顏色。
第十一圖顯示一個安放次序表，其提供能夠在許多情況下允許完全充電同時維持系統簡單性之示範性的結果及事件。第十一圖中所有裝置、瓦特數、排序、及其他可易於取得之變數係示範性的，此為一般熟於本項技藝人士所承認的。
第十二圖顯示一個四單元的充電器，其使用本發明之方法。無線電源供應1214包含多數個初級線圈LP1~LP4。每一線圈包含一個開關，其受到WPS控制1220之控制。該開關係受到驅動控制之控制而選擇性地充電該裝置。
第十三圖顯示一WPS1314，其中額外的容量係加以提供而無需完全的電源供應範圍來進行適當的分配。具體而言，WPS1314包含兩個驅動控制1320a及1320b，其中每一者控制兩個初級線圈。典型地，每一單元或線圈可能需要每一裝置之最大電源供應支持(maximum power supply support per device)。其例子可為4~5瓦特的裝置或20瓦特。第十三圖中的例子可提供10瓦特，相對地第十二圖係提供5瓦特。它們係設計上可構形的，以取得最佳性能。
作為一個用途的例子，第十二圖及第十三圖的WPS 1214及1314，係適用於會議室桌子、飛行器分配系統、汽車問題解決(automotive solution)、及其他可能限制電力可取得性的應用。
第十四圖顯示一系統1410及一個相關的方法，其在二級裝置1416中使用二級裝置電力管理單元(PMU)(未示)，而較佳地進行控制、調整、及預測電力振盪。這些改變在其發生時或發生前係加以傳訊。
系統1410包含一電源供應1412、一無線電源供應1414、及一無線供電裝置1416。這些元件在先前均有所描述。此外，裝置1416的PMU係與無線供電控制1420及裝置控制1424加以通訊。
典型的無線供電系統係對負載中的改變作出反應，及所示的途徑允許該系統共同工作。二級命令使得改變能夠基於所預測的變異加以進行。無線電源供應1414使用該裝置電力管理單元(PMU)來追踪及回應系統之需求(藉由在所預期之所需電力之前調整PID)。這樣減少時間及控制先前提及之對新需求所反應的問題。
在第十四圖中顯示一個示範性的負載需求，其中電力係從基礎電力層次逐漸增加，而額外地、有次序地供電至背光及一硬裝置。由於二級裝置能夠預測在該裝置內的這類需求，所以在電力需求將要改變時，二級裝置控制1424能夠讓無線供電控制1420提前”知悉”。
無線供電控制1420可直接與二級裝置的電力管理單元(PMU)進行通訊。這個資訊可以注入PID迴路中。這個途徑令電源供應能夠在較小功率容量之下加以建立。
