電子裝置Electronic device
本發明大體而言係關於電子裝置，更具體而言係關於可提供資料及電力傳輸傳輸之裝置。The present invention relates generally to electronic devices, and more particularly to devices that provide data and power transmission.
集線器擴展了電子裝置之連接能力。實例為USB集線器，其允許諸如鍵盤、滑鼠、記憶體及數位相機之多個裝置連接至諸如膝上型電腦或行動電話之另一裝置之一USB埠。 電源組為電子裝置之行動電源。電源組可將電力供應至諸如膝上型電腦、行動電話及平板之電子裝置。電源組亦可為此等電子裝置之電池充電。 現代消費者往往攜載多於一個行動裝置，諸如一個行動電話及一個平板。因此，對其來說另外攜載集線器及電源組兩者將不方便。此外，集線器及電源組配有個別專用纜線，因此攜載集線器及電源組兩者致使攜載單獨纜線，對現代消費者造成不便。The hub expands the connectivity of the electronic device. An example is a USB hub that allows multiple devices such as a keyboard, mouse, memory, and digital camera to be connected to one of the other devices, such as a laptop or mobile phone. The power pack is the mobile power source of the electronic device. The power pack can supply power to electronic devices such as laptops, mobile phones, and tablets. The power pack can also charge the batteries of such electronic devices. Modern consumers often carry more than one mobile device, such as a mobile phone and a tablet. Therefore, it is inconvenient for it to carry both a hub and a power pack. In addition, the hub and the power pack are equipped with individual dedicated cables, so that both the carrying hub and the power pack cause the carrying of a separate cable, which is inconvenient for modern consumers.
在一或多項實施例中，提供裝置。裝置包括第一埠、第二埠、電池及電力控制單元。電力控制單元電連接至電池、第一埠及第二埠。電力控制單元經組態以基於來自電池之輸出而進行以下操作：將第一電力信號傳輸至第一埠且將第二電力信號傳輸至第二埠；或將由第一埠接收之第三電力信號傳輸至第二埠。 在一或多項實施例中，提供裝置。裝置包括第一埠、第二埠、電力控制單元、電池及集線器控制單元。電力控制單元電連接至第一埠及第二埠。電池電連接至電力控制單元。集線器控制單元電連接至第一埠、第二埠及電力控制單元。電力控制單元將第一電壓輸出至第一埠且將不同於第一電壓之第二電壓輸出至第二埠。In one or more embodiments, a device is provided. The device includes a first port, a second port, a battery, and a power control unit. The power control unit is electrically connected to the battery, the first port and the second port. The power control unit is configured to perform the following operations based on the output from the battery: transmitting the first power signal to the first port and transmitting the second power signal to the second port; or transmitting the third power signal received by the first port Transfer to the second page. In one or more embodiments, a device is provided. The device includes a first port, a second port, a power control unit, a battery, and a hub control unit. The power control unit is electrically connected to the first port and the second port. The battery is electrically connected to the power control unit. The hub control unit is electrically connected to the first port, the second port, and the power control unit. The power control unit outputs the first voltage to the first chirp and outputs a second voltage different from the first voltage to the second chirp.
電子裝置經常提供單個功能。舉例而言，集線器擴展了一個埠之連接能力。舉例而言，USB集線器允許多於一個裝置連接至一個USB埠。作為另一實例，包含電池之電源組可將電力供應至使用中之其他電子裝置。其亦可為其他電子裝置之內部電池(若存在一個)，不管其他電子裝置是否在使用中。電源組可經由標準化埠(諸如USB埠)供應電力。電源組可經由非標準化埠供應電力。在本發明之一些實施例中，埠可同時攜載資料傳輸及電力傳輸。 經常期望具有提供多於一個單個功能之裝置。舉例而言，將集線器及電源組之功能組合至一個多功能裝置中將為有利的。多功能裝置可減少消費者必須攜載之裝置之數目同時提供相同位準之便利。此外，多功能裝置可減少消費者必須攜載以便使用不同單功能裝置之纜線之數目。在一些實施例中，與集線器之資料傳輸及與電源組之電力傳輸需要不同類型之纜線。在一些實施例中，多功能裝置將標準化介面用於資料及電力傳輸兩者，藉此減少消費者必須攜載之纜線之類型之數目同時其可仍享受相同或近似相同便利量。 圖1說明電子裝置10。電子裝置10包括埠101、埠102、埠103、埠104、電池20、啟動工具311及傳信單元321。 埠101至104中之每一者可連接至其他裝置。如圖1中所說明，可連接至電子裝置10之裝置包括但不限於裝置30、41、42、43、50及60。預期，電子裝置10根據本發明之一些其他實施例可包括除埠101至104外之多個埠。根據本發明之一些其他實施例，埠101至104中之一或多者可消除或省略。 充電器70亦可連接至電子裝置10。儘管圖1展示六個裝置30、41、42、43、50及60且充電器70可連接至電子裝置10，可連接至電子裝置10之其他數目個裝置亦為可能的，此取決於使用情景。在一些實施例中，僅一個裝置連接至電子裝置10。在一些實施例中，僅一個充電器連接至電子裝置10。在一些實施例中，兩個、三個、四個、五個、六個或更多裝置可連接至電子裝置10。在一些實施例中，除任何數目個裝置外，一或多個充電器亦可連接至電子裝置10。 埠101、102、103、104可為相同、相似或不同類型之埠。埠101、102、103、104可攜載資料傳輸、電力傳輸或兩者。在一些實施例中，埠101、102、103、104中之一些或全部可符合標準化規格，諸如通用串列匯流排規格(包括但不限於USB 1.0、USB 1.1、USB 2.0、USB 3.0、USB 3.1、USB 3.2、USB電池充電1.0、USB電池充電1.1、USB電池充電1.2、USB電力遞送(PD)版本1.0、USB PD版本2.0、USB PD版本3.0、USB C類型1.0、USB C類型1.1及未來版本)；不同埠可符合相同標準化規格之不同版本。在一些實施例中，埠101、102、103、104中之一些或全部可為音訊-視覺介面，諸如VGA、HDMI、DVI、迷你DVI、微DVI及迷你顯示埠(MiniDP)。在一些實施例中，埠101、102、103、104可屬於專屬類型且具有可自訂功能性。在實施例中，埠101可為串流上行埠(upstream facing port，UFP)，且埠102可為串流下行埠(downstream facing port，DFP)，且反之亦然。在一些實施例中，埠101及102為USB匯流排，其中每一者包含(VBUS、C1/C2、D+/D-_1、D+/D-_1、SUB1/SUB2、USB3.0)之接腳。 在圖1中所說明之實施例中，裝置30可為主機裝置，諸如桌上型電腦、膝上型電腦、行動電話、智慧型電話、平板及可經由裝置30之埠31連接至埠101的其他裝置。裝置30亦包含內部電池32。裝置30可藉由內部電池32為其自身供電，或自外部電源接收電力。埠31可用於與電子裝置10之埠(諸如埠101)之資料傳輸及電力傳輸兩者。內部電池32例如經由埠31藉由外部電源可再充電。在一些實施例中，埠31為USB埠。 裝置41、42、43、50可連接至埠102、103及其他埠，且可用於資料傳輸及電力傳輸兩者。裝置41、42、43、50之實例包括但不限於記憶體、硬碟機、鍵盤、電腦滑鼠、指標、數位相機、閃光燈及通風扇。在一些實施例中，裝置41、42、43、50可具有支援相同或不同版本之USB介面。 裝置60可為外部顯示器，其可經由音訊-視覺介面或USB介面或另一標準化或專屬介面而連接至埠104。 充電器70可將電力供應至電子裝置10且經由電子裝置10供應至裝置41、42、43、50及60。充電器70可連接至以諸如110 V及220 V之電壓操作之AC/DC電力出口，或連接至其他電源。 啟動工具311可由電子裝置10之使用者控制以啟動特定功能。在一些實施例中，啟動工具311為按鈕，使用者可按壓按鈕以啟動電池20以將電力供應至連接至電子裝置10之裝置。啟動工具311可具有其他實體外觀，諸如開關、控制桿、手柄、光學/聲學/電/熱/氣味感測器。 傳信單元321指示電子裝置10之狀態。在一些實施例中，傳信單元321可為燈或發光二極體(LED)。在一些實施例中，傳信單元321可指示電池20的電量。例如，傳信單元321可經組態以用不同色彩或強度發光以指示電池20之不同電量。作為實例，傳信單元321可為單色LED (其比多色光源偏移)，在其發光時，指示低電池電量。 根據本發明之實施例，裝置30為連接至埠101之智慧型電話，裝置41、42、43分別為鍵盤、滑鼠及揚聲器，裝置50為USB記憶卡，裝置60為高解析度外部顯示器60。在此實施例中，裝置41、42、43、50、60經由電子裝置10連接至裝置30之埠31，電子裝置10在此狀況下提供集線器之功能。裝置41、42、43、50、60可自智慧型電話30汲取電力，或若電池電量足夠且使用者藉由使用啟動工具311來啟動電池20，則自電池20汲取電力。電子裝置10因此亦提供電源組之功能。根據本發明之實施例，充電器70為連接至110 V室內AC電力出口(未展示)之電源配接器且另外連接至電子裝置10。在此實施例中，充電器70可將電力供應至裝置30、41、42、43、50、60且對電子裝置10之電池20進行充電。 為進一步描述電子裝置10之功能性，下文提供根據本發明之不同使用情景及不同實施例。 參考圖2A中所說明之使用情景。僅充電器70經由埠101連接至電子裝置10。充電器70可對電子裝置10之電池20進行充電。充電器70可在電池20為滿的情況下停止充電。 參考圖2B中所說明之使用情景。僅充電器70經由埠102連接至電子裝置10。充電器70可對電子裝置10之電池20進行充電且可在電池20為滿的情況下停止充電。自圖2A及圖2B將清楚埠101及102皆能夠進行電力傳輸。 參考圖2C，其描繪埠101及102兩者經連接之情景。裝置30及充電器70分別連接至埠101及埠102。充電器70可將電力供應至裝置30，或對裝置30之內部電池32進行充電，或進行兩者。充電器70可對電子裝置10之電池20進行充電。在一些實施例中，充電器70可同時將電力供應至裝置30且對電池20進行充電。在一些實施例中，充電器70可對電池20進行充電且裝置30透過其特有內部電池32進行操作。其他使用亦為可能的。 參考圖2D，其描繪埠101及102兩者經連接之情景。充電器70及裝置41分別連接至埠101及埠102。充電器70可將電力供應至裝置41。充電器70可對電子裝置10之電池20進行充電。在一些實施例中，充電器70可同時將電力供應至裝置41且對電池20進行充電。在一些實施例中，充電器70可將電力供應至裝置41而無需對電子裝置10之電池20進行充電。其他使用亦為可能的。 圖2E類似於圖2D，因此不重複可能操作條件。在一些實施例中，埠102及103可具有不同能力，支援不同標準，或支援相同標準之不同版本，因此可連接至埠103之裝置50可不連接至埠102或可在減少功能性的情況下連接至埠102。舉例而言，若埠102支援USB 3.0且埠103支援USB 2.0，則具有USB 3.0能力之裝置必須連接至埠102以便使用USB 3.0功能性。在一些實施例中，埠102支援USB PD而埠103不支援，在此狀況下用埠103不可能進行USB電力遞送。 圖2F可視為圖2D及2E中所描繪之情景組合之情景。充電器70可對電子裝置10之電池20進行充電。充電器70可將電力供應至裝置41。充電器70可將電力供應至裝置50。充電器70可對電子裝置10之電池20進行充電且將電力供應至裝置41、50。充電器70可將電力供應至裝置41、50而無需對電池20進行充電。 充電器70在圖2A至圖2F中所描繪之全部情景中連接至電子裝置10。充電器70可對電子裝置10之電池20進行充電，可將電力供應至連接至電子裝置10之裝置，或可同時進行兩者。在一些實施例中，電子裝置10可被視為在圖2A至圖2F中所描繪之情景中以「充電模式」操作。 將充電器70一直連接至電子裝置10並非必需的；圖3A至圖3C描繪例示性情景。 參考圖3A，其中僅裝置30連接至電子裝置10。在一些實施例中，裝置30為智慧型電話。若電池20之電量足夠，則裝置30可自電子裝置10接收電力。裝置30可透過其特有內部電池32進行操作而不管電池20是否具有足夠電力。電子裝置10之使用者可藉由傳信單元321知曉電池20之狀態。使用者可選擇藉由啟動工具311來啟動電子裝置10之充電功能，諸如藉由按壓該啟動工具來使電子裝置10將電力供應至裝置30。在一些實施例中，裝置30之內部電池32可將電力供應至電子裝置10之電池20。 圖3B及圖3C類似於圖3A，其中不同之處在於哪些裝置連接至電子裝置10及裝置連接至電子裝置10至哪些埠。圖3中所揭示之操作條件亦適用於圖3B及3C，可能具有在熟習此項技術者之水平內之必要修改。 在圖3A至圖3C中所描繪之情景中無任何充電器70連接至電子裝置10 。裝置30、41及50可自電子裝置10之電池20汲取電力。在一些實施例中，電子裝置10可被認為在圖3A至圖3C中所描繪之情景中以「電源組模式」操作。 圖4A及圖4B描繪電子裝置10之其他可能使用情景。 參考圖4A，其中裝置30連接至埠101且裝置41連接至埠102。根據本發明之實施例，裝置30可為包含埠31及內部電池32之主機裝置，諸如智慧型電話或平板。根據本發明之實施例，裝置41可為需要外部電源操作之周邊裝置。在一些實施例中，裝置41為USB記憶卡或鍵盤。在一些實施例中，除裝置41外之裝置連接至埠102。在圖4A中所描繪之實施例中，電子裝置10可擴展主機裝置30之埠31之連接能力。電子裝置10亦可藉由電池20將電力供應至主機裝置30及外圍裝置41。圖4A中所描繪之實施例不同於簡單集線器裝置，其中周邊裝置41必須自主機裝置30汲取電力。藉由消除對將來自主機裝置30之電力供應至周邊裝置41的需求，電子裝置10可節省主機裝置30之內部電池32之電力。藉由能夠將電力供應至主機裝置30及周邊裝置41兩者，電子裝置10可甚至在內部電池32含電量低時保持主機裝置30操作。 圖4B與圖4A之不同之處在於充電器70另外連接至電子裝置10。根據本發明之實施例，裝置30可為包含埠31及內部電池32之主機中之，諸如智慧型電話或平板。根據本發明之實施例，裝置41可為需要外部電源操作之周邊裝置。在一些實施例中，裝置41為USB記憶卡或鍵盤。在一些實施例中，除裝置41外之裝置連接至埠102。充電器70提供可供應電力至裝置30及41之電源之額外選擇。充電器70可對電子裝置10之電池20進行充電。 在圖4A及圖4B中所描繪之情景中，多於一個電源可用，諸如電子裝置10之電池20、裝置30之內部電池32及充電器70。圖5A說明根據本發明之實施例之用以判定使用哪一電源來對哪一裝置供電/充電之例示性方法。 參考圖5A。電子裝置10首先判定連接充電器還是外部電力供應器。若存在一者，則充電器/外部電力供應器將電力供應至連接至電子裝置10且可視情況對電子裝置10之電池20進行充電。自外部電力供應器汲取電力只要可能即具有節省主機裝置之內部電池及電子裝置10之電池20的益處，藉此增加主機可透過其特有內部電池運行之時間長度及電子裝置10之電池20可供應之電力之量。 若不存在任何充電器或外部電力供應器，則電子裝置10判定是否啟動其電池20 (藉助於例如啟動工具311)。若其未經啟動，則電子裝置10之充電未經啟動，且無其特有電源之裝置(諸如鍵盤或滑鼠)將不得不自具有其特有電源之裝置(諸如智慧型電話、膝上型電腦或平板)汲取電力。 若電池20經啟動，則電子裝置10判定電池20是否具有足夠電力。若狀況如此，則連接至電子裝置10之裝置可自電池20汲取電力。 若電池20經啟動但電池20不具有足夠電力，則電子裝置10之充電未經啟動，且無其特有電源之裝置(諸如鍵盤或滑鼠)將不得不自具有其特有電源之裝置(諸如智慧型電話、膝上型電腦或平板)汲取電力。 圖5B說明根據本發明之實施例之用以判定使用哪一電源來對哪一裝置供電/充電的例示性方法。 首先類似於圖5A判定連接至電子裝置10之充電器或外部電力供應器之存在。提早進行此判定允許較佳節省連接至電子裝置10之裝置之電池。 然後，電子裝置10判定電池20是否具有足夠電力。若電池不具有足夠電力，則無其特有電源之裝置(諸如鍵盤或滑鼠)將不得不自具有其特有電源之裝置(諸如智慧型電話、膝上型電腦或平板)汲取電力。在一些實施例中，傳信單元321將指示低電池電量，通知使用者此情況且提示使用者對電子裝置10之電池20進行充電。 若電池具有足夠電力，則電子裝置10判定是否啟動電子裝置10之充電功能(藉助於例如啟動工具311)。若該充電功能經啟動，則連接至電子裝置10之裝置可自電池20汲取電力。若該充電功能未經啟動，則無其特有電源之裝置(諸如鍵盤或滑鼠)將不得不自具有其特有電源之裝置(諸如智慧型電話、膝上型電腦或平板)汲取電力。 圖6說明根據本發明之一些實施例之電子裝置10之更詳細方塊圖。除埠101、102、103、104及電池20，電子裝置10包含集線器控制單元100及電力控制單元200。電池20連接至電力控制單元200。集線器控制單元100連接至埠101至104及電力控制單元200。電力控制單元200連接至電池20、集線器控制單元100以及埠101及102。在一些實施例中，電力控制單元200亦可連接至埠103及104。 集線器控制單元100在所連接埠之間提供資料傳輸。集線器控制單元100可提供集線器功能。集線器控制單元100可提供資料多工/解多工功能。在一些實施例中，集線器控制單元100基於標準化規格，諸如USB規格。 電力控制單元200。在所連接埠、電池及區塊之間提供電力傳輸在一些實施例中，電力控制單元200可在所連接埠、電池及區塊間發送及接收複數個相同、相似或不同電力信號。複數個電力信號可處於不同電壓，諸如0 V、1 V、2 V、3 V、4 V、5 V、6 V、7 V、8 V、9 V、10 V、11 V、12 V、13 V、14 V、15 V、16 V、17 V、18 V、19 V、20 V、超過20 V之任何合適電壓，及任何合適非整數電壓。複數個電力信號可具有任何合適量之電流或電力。複數個電力信號可處於不同電壓範圍中。在一些實施例中，電力控制單元200可提供資料傳輸。在一些實施例中，集線器控制單元100基於標準化規格，諸如USB規格及USB PD規格。根據本發明之實施例，電力控制單元200可自電池20接收一或多個電力信號且將所接收電力信號傳輸至所連接埠及區塊中之任一者。電力控制單元200可以各種不同電壓傳輸電力信號，諸如處於不同於自埠101、102或電池20接收之電力信號之電壓。電力控制單元200可偵測連接至電池20連接至之埠之電力信號。電力控制單元200可偵測電池20之狀態，諸如電池電量。 可參考圖6之實施例進一步闡釋圖2A、圖2B、圖2C、圖2D、圖2E、圖2F、圖2G、圖3A、圖3B、圖3C、圖4A及4B之使用情景之操作。 在圖2A之使用情景中，電力控制單元200可判定是否對電池20進行充電。若進行充電，則電力信號可經由埠102自充電器70流動至電力控制單元200，且接著電力控制單元200可將電力信號引導至電池20。在自埠101接收電力信號時，電力控制單元200可在將電力信號引導至電池20之前對該電力信號作出修改或改變。修改或改變可與任何合適電特性(諸如電壓、電流、電力、頻率、工作循環等)有關。在一些實施例中，電力控制單元200可判定電池20並非不得不被充電，在此狀況下，充電器70可選擇不輸出電力信號或電力控制單元200可切斷自埠101接收之電力信號。 圖2B之使用情景類似於圖2A之使用情景，惟除充電器70連接至埠102。由於埠101及102可具有類似能力，因此關於圖2A之上述闡釋亦適用於圖2B且因此不重複。 在圖2C之使用情景中，電力控制單元200可判定是否對電池20進行充電。若進行充電，則電力信號可經由埠101自充電器70流動至電力控制單元200，且接著電力控制單元200可將電力信號引導至電池20。在自埠102接收電力信號時，電力控制單元200可對電力信號之任何合適電特性(諸如電壓、電流、電力、頻率、工作循環等)作出修改或改變。在一些實施例中，電力控制單元200可判定電池20並非不得不被充電，在此狀況下，充電器70可選擇不輸出電力信號。在一些實施例中，電力控制單元200或裝置30可判定裝置30自充電器70接收電力。在此狀況下，電力控制單元200基於自充電器70接收之電力信號將電力信號傳輸至埠101。此外，電力控制單元200可修改自充電器70接收之電力信號之任何電特性且符合傳輸至埠101之電力信號之需求。在一些實施例中，除充電器70外或替代該充電器，電池20可將電力提供至裝置30。 圖2D之使用情景類似於圖2C之使用情景，惟除充電器70連接至埠101及裝置41而無需其特有電池連接至埠102。因此，電力控制單元200可另外判定將是否自電池20汲取電力以供應裝置41。 圖2E之使用情況類似於圖2D之使用情況。在一些實施例中，埠101、102、103具有不同規格或能力且因此埠101、102、103中之每一者可處置之電力信號之電特性不同。電力控制單元200將接著對所接收電力信號作出必要修改且接著傳輸經修改電力信號。 圖2F之使用情景與圖2D及圖2E不同之處在於多於一個裝置連接至電子裝置10。電力控制單元200可藉由例如自充電器70汲取更多電力或自電池20汲取額外電力或兩者來將多於一個電力信號輸出至不同裝置。 在圖2A至圖2G之情景中，電力控制單元200可判定是否自充電器70汲取電力，是否對電池20進行充電或自該電池汲取電力，及輸出具有符合連接至電子裝置10之裝置之電力供應要求之電特性之電力信號的方式。電力控制單元200之優勢為使用/充電電池20之靈活性以最佳利用電池且延長電池20之使用壽命。另一優勢為將電力供應至可具有不同電力供應要求之諸多裝置的能力。 電力控制單元200可使用不同方法來判定對電池20進行充電或自該電池汲取電力。在一些實施例中，電力控制單元200可偵測電池20中可用之電力之量。在一些實施例中，電力控制單元200可偵測電池20能夠輸出之電壓或電流之量。 圖3A至圖3C之情景無一者涉及充電器70。電力控制單元200判定電池20之電量，且供應具有可能不同電特性之電力信號以滿足連接至電子裝置10之不同裝置之需求及電子裝置10之埠之不同能力。在一些實施例中，諸如圖3A中所說明，電力控制單元200在判定是否自電池20汲取電力中檢查啟動工具311是否經觸發。

Electronic devices often provide a single function. For example, a hub extends a single connection. For example, a USB hub allows more than one device to be connected to a USB port. As another example, a power pack containing a battery can supply power to other electronic devices in use. It can also be the internal battery of another electronic device (if one exists), regardless of whether other electronic devices are in use. The power pack can be powered via a standardized port (such as a USB port). The power pack can supply power via a non-standardized turn. In some embodiments of the invention, the device can carry both data transmission and power transmission. It is often desirable to have a device that provides more than one single function. For example, it would be advantageous to combine the functions of a hub and a power pack into a multi-function device. Multi-function devices reduce the number of devices that consumers must carry while providing the same level of convenience. In addition, the multi-function device can reduce the number of cables that consumers must carry in order to use different single-function devices. In some embodiments, different types of cables are required for data transfer with the hub and for power transfer with the power pack. In some embodiments, the multi-function device uses a standardized interface for both data and power transmission, thereby reducing the number of types of cables that the consumer must carry while still enjoying the same or approximately the same amount of convenience.

No charger 70 is connected to the electronic device 10 in the scenario depicted in Figures 3A-3C. Devices 30, 41, and 50 can draw power from battery 20 of electronic device 10. In some embodiments, electronic device 10 can be considered to operate in "power pack mode" in the scenarios depicted in Figures 3A-3C. 4A and 4B depict other possible usage scenarios for the electronic device 10. Referring to Figure 4A, device 30 is coupled to port 101 and device 41 is coupled to port 102. In accordance with an embodiment of the present invention, device 30 can be a host device including cassette 31 and internal battery 32, such as a smart phone or tablet. In accordance with an embodiment of the present invention, device 41 may be a peripheral device that requires external power operation.

In the embodiment depicted in FIG. 4A, the electronic device 10 can extend the connectivity of the port 31 of the host device 30. The electronic device 10 can also supply power to the host device 30 and the peripheral device 41 by the battery 20. The embodiment depicted in FIG. 4A differs from a simple hub device in that peripheral device 41 must draw power from host device 30. The electronic device 10 can save power of the internal battery 32 of the host device 30 by eliminating the need to supply power from the host device 30 to the peripheral device 41.

If there is one, the charger/external power supply supplies power to the electronic device 10 and optionally charges the battery 20 of the electronic device 10. The power drawn from the external power supply has the benefit of saving the internal battery of the host device and the battery 20 of the electronic device 10, thereby increasing the length of time that the host can operate through its unique internal battery and the battery 20 of the electronic device 10 is available. The amount of electricity. If there is no charger or external power supply, the electronic device 10 determines whether to activate its battery 20 (by means of, for example, the starter tool 311). If it is not activated, the charging of the electronic device 10 is not activated, and the device without its own power source (such as a keyboard or a mouse) will have to be from a device with its own power source (such as a smart phone, a laptop) Or tablet) draw power. If the battery 20 is activated, the electronic device 10 determines whether the battery 20 has sufficient power. If this is the case, the device connected to the electronic device 10 can draw power from the battery 20. If the battery 20 is activated but the battery 20 does not have sufficient power, the charging of the electronic device 10 is not activated, and a device without its own power source (such as a keyboard or a mouse) will have to be self-contained with its own power supply (such as wisdom).

If the battery does not have sufficient power, devices without their own power source (such as a keyboard or mouse) will have to draw power from devices with their own power source, such as smart phones, laptops or tablets. In some embodiments, the signaling unit 321 will indicate a low battery level, notify the user of the condition and prompt the user to charge the battery 20 of the electronic device 10. If the battery has sufficient power, the electronic device 10 determines whether to activate the charging function of the electronic device 10 (by means of, for example, the activation tool 311). If the charging function is activated, the device connected to the electronic device 10 can draw power from the battery 20. If the charging function is not activated, devices without their own power source (such as a keyboard or mouse) will have to draw power from a device with its own power source, such as a smart phone, laptop or tablet.

In the usage scenario of FIG. 2A, the power control unit 200 can determine whether to charge the battery 20. If charging is performed, the power signal may flow from the charger 70 to the power control unit 200 via the port 102, and then the power control unit 200 may direct the power signal to the battery 20. Upon receiving the power signal from the port 101, the power control unit 200 can make modifications or changes to the power signal before directing the power signal to the battery 20. Modifications or changes may be related to any suitable electrical characteristics such as voltage, current, power, frequency, duty cycle, and the like. In some embodiments, the power control unit 200 can determine that the battery 20 does not have to be charged, in which case the charger 70 can choose not to output a power signal or the power control unit 200 can cut off the power signal received from the battery 101. The usage scenario of Figure 2B is similar to the usage scenario of Figure 2A except that charger 70 is coupled to port 102. Since 埠101 and 102 can have similar capabilities, the above explanation with respect to FIG. 2A also applies to FIG. 2B and thus is not repeated. In the usage scenario of FIG. 2C, the power control unit 200 can determine whether to charge the battery 20. If charging is performed, the power signal may flow from the charger 70 to the power control unit 200 via the crucible 101, and then the power control unit 200 may direct the power signal to the battery 20.
