五、新型說明: 【新型所屬之技術領域】 • 本創作係有關於一種具電池壽命檢測功能之充電器,尤指一種兼 . 具充電及顯示電池即時之電容量與壽命值等資訊之充電器。 【先前技術】 隨著科技發達與進步’各種攜帶式的電子產品及設備已日漸普 ^遍’而且已逐漸成為社會大眾生活中不可或缺的重要家電產品。而且 全球對儲能設備也越來越重視,其中可充式(Rechargeat)le)的二次電 池逐漸成為市面上的主流,但二次電池仍有許多潛在性的危險與缺 點。由於二次電池的可用容量會隨著使用者的使用耗損以及充放電次 數與時數的增加而遞減,亦即電池容量亦會逐漸下降而有壽命上的考 量’因而造成消費者在使用時有所限制,加上市售電池充電器無法顯 不電池可用的電容量,以致無法得知電池實際的使用情況,所以在二 ·次電池普及化的現代,電池品質及壽命的監測顯得更加重要。 一般充電器大多數僅是具有基本的充電功能而已,最多以Led燈 顯示的方式來表示電池充電時的充電容量高>1氏,因而無法顯示充電中 的電池正確含電容量與内部耗損的狀態。更何況市面上常見的充電裝 置所使用的充電方式不外乎是使用定電流充電、定電壓充電或是定電 流定電壓兩段式充電、脈衝電流充電等方式,只是為在盡量不影響電 池壽命的情況下,使電池加速充飽電,亦有其他不同的功能,例如使 M406871 vr 用USB充電、自動偵測正負極充電、評估電池充電容量等等,但是仍 然沒有可以偵測並判讀充電電池各項使用數據並顯示的充電器。 一般電池之電容量會隨著放電深度不同而有所不同,亦即電池的 電容量會隨著使用週期、時數與放電深度而有所改變,且電池殘留電 容量會隨著電池老化程度而有所不同,因此使得電池的殘電容量較難 估測。以下對習知的電池之電容量偵測技術方法做一說明: (1) 比重法(specific gravity):如附件二參考文獻[9]所示,以 鲁比重計測電解液的比重做為容量的偵測。由於電解液在電池充放電時 濃度不同’充電過程電解液濃度上升,放電過程電解液濃度下降,因 此電解液濃度與充電狀態具有線性關係,但量測時須等比重均勻分 布,因此’時間上的延遲會造成即時量測失準。此測量法常見於汽車、 機車所用之蓄電池。 (2) 開路電壓法(open circuit voltage):如附件二參考文獻[9] 鲁所示,電池充電完畢後,其端電壓會隨時間而開始慢慢下降。電池放 電完畢後,其端電壓會隨時間而慢慢上升。與比重計法相同,皆須等 待一段較長的靜止穩定時間才可用此方法進行量測。此測量法常見於 水銀電池。 (3) 加載電壓法(loaded voltage):如附件二參考文獻[9]所示, 依據電池接上負紐之加載電壓值來估測電池容量Μ法適合用於固 定負載條件下來指科池可用容量’是侧操作狀態下電池容量最常 M406871 用的方法。因此當負載變大或變小時,指示容量也隨之改變。此測量 法常見於一般電池。 (4)庫倫測量法(coulometric measurement):如附件二參考文獻 « -[9]所示,主要測量由電池充入或放出的電流量對時間積分來計算電 池容量。以放電電流與放電至終止電壓的這段時間之積分表示電池容 量Ah: • 4 = J .办 ίί〇 其中^(t)為隨著時間而改變的放電電流,k為放電 狀態的初始時間,k為放電狀態最終時間。在加載情況下,是一種實 用的測量方式,且適用各種電池,但此法的先決條件是必須先知道電 池内已有的容量才能獲得較準確的電池容量。常見於電流充電裝置。 依據目前所知,利用上述開路電壓法的代表性專利前案如本國新 型專利第M350170號『可偵測電池剩餘電容量之兩用充電器』,如附 φ件二參考文獻[7]所示,以及新型專利第M389393號『節能充電器』, 該等習用結構僅是以比較電路依照内定參考電壓而與量測電壓加以 比較而已’然後依據比較結果來輸出高低電位,藉以驅動點亮發光二 極體(LED) ’並以發光二極體(led)點亮的數量來顯示電池電容量的多 寡。 該等習用結構並無電池壽命運算機制的設置,所以僅能粗略的計 算出電池的電容量,由於其估算之電容量數值不夠精確的緣故,故無 5 M406871 法正確的顯示電池實際的電容量以及電池的所剩壽命資訊,從而誤導 使用者對電池使用壽命的判斷,以致不當的對電池充放電而導致的電 能耗費以及危險情事的發生,因而造成充電使用上的不便與困擾,故 該等習用結構確實有再改良的必要性。 另有一種習用結構如本國發明第1279573號『可偵測電池額定容 量並依電池額定容量來決定充電電流之電池充電方法』,其係以一種 電池額定容量偵測裝置與方法,用以得知電池的額定容量,並依其額 定容量算出其最適合充電電流值來對電池充電,而可根據不同額定容 量的電池,以不同的充電電流進行充電,使不同額定容量的電池均可 達到最佳之充電效果者。 該習用結構雖然可以偵測出電池的額定電容量,再以適合之充電 電流來對電池進行充電,惟,該習用結構不具備顯示單元以及電池壽 命的運算機制,所以該習用結構無法檢測及顯示電池的實際電容量與 電池的使用壽命等資訊,從而容易誤導使用者對電池使用壽命的判 斷,以致不當的對電池充放電而導致的電能耗費以及危險情事的發 生,因而造成充電使用上的不便與困擾,故該等習用結構破實有再改 良的必要性。 另有一種相關之習用結構如本國發明第465133號『電池組』,其 可判定電池功能狀態的喪失,以進行充放電的控制、強制放電的控制 的電池組,其具備充放電控制機構’係將電池充放電者;強制放電控 6 M406871 制機構係將各單元強制放電者;功能檢測機構係用以檢測電池組的功 能狀態者;判定機構4、5,係判定由該功能檢測機構所檢測出的功能 狀H ;及控制機婦顧㈣欺機構所得之功能狀態喪失 的判定’有選雜地湖上奴放電㈣機構與強做電㈣麵。 該習用結構具備電池壽命的功能喪失判定的功能,並可按照該判 定而進行相騎充放電控φ卜齡】放電㈣,雜可以讓電池安全無 虞的使用’惟,其壽命運算機制係以電池的使用賴、使用時數、計 數充放電触數與响等g絲純欺,所以制服構的電池壽 命的判疋數值僅是粗略的估算而已,由於電池壽命數值不夠精確的緣 故,所以僅能夠作為電池使用的參考,加上其整體結構非常複雜,因 而導致製造成本過於昂貴,以致無法大量的普及應用,況且該習用結 構之電池組並無顯示單元的設置,僅能透過通信設備傳輸至遠端的電 腦,藉以觀看電池的各項參數資訊,於此造成充電使用上的觀看不便 與極大的困擾。 緣是’因鑑於上述習用結構所產生的缺失,因此,本創作人等乃 積極努力研究’經潛心開發,終於研發出一種 >確具實用功效的本創作β 【新型内容】 本創作第一目的在於,提供一種具電池壽命檢測功能之充電器, 主要具備電池效能顯示、充放電指數顯示、即時充放電流顯示以及自 動斷電等諸多功能,不僅可以檢測與顯示電池之電容量與使用壽命等 7 M406871 k讯,藉以快速驗證電池是否為良品,實際電容量是否與標示的數值 吻合,並且可以進一步了解電池内部損耗的情形以及充放電動作是否 正常,故可對各種類型充電電池做即時的把關與嚴密的監測,因而具 有節省電能、避免再次購買到不良劣質的電池,並可避免因不當的電 池充放電所導致之危險情事的發生。 為達成上述功效,本創作採用之技術手段係包括一第一基座、訊 號擷取單元、一運算手段、顯示單元及一充電控制電路,係於第一基 座一面上設置一供電池容置的第一置放槽,第一置放槽設有至少一對 可供電池電性搭接其上的第一電極組,並於第一基座設置包括一與第 一電極組電性連接的訊號掘取單元,用以感測充電中之電池的電流或 是電壓狀態而產生一感測訊號,運算手段則將感測訊號轉換為一與電 池即時之電容量相應的充放電指數值及一壽命值,顯示單元則將充放 電指數值顯示為充放電指數資訊,且充電控制電路可受運算手段的觸 發而控制電池的充電時機者。 本創作第二目的在於,提供一種可以本創作可直接結合在任何市 售充電裝置上的具電池壽命檢測功能之充電器,使原本充電器的功能 可以升級為智慧型充電裝置,故而不需另外購買以節省購置成本。 為達成上述功效,本創作採用之技術手段係包括一用以與該第一 基座結合的第二基座,該充電控制電路設置在該第二基座上,該第二 基座設置有一供電池容置的第二置放槽,該第二置放槽設有至少一對 可供該電池電性搭接其上的第二電極組;該第__基座異於該第一置放 槽之-面上延伸設有-與該第二置放槽配合的嵌合結構,該嵌合結構 之二端面分別設有至少-對可以電性搭接在該第二基座之該第二電 極組上的第三電極組,且該第二基座上設有—可對電池充電的電源供 應單元。 【實施方式】 壹•本創作技術概念與應用 4參看第-至四圖所示’本創作技術概念是將庫倫測量法及電池 壽命的運賴做充電裝置做—整合’並可透顧置在充電裝置上的 顯不單元(50)(即LCD顯示器),讓使用者可以方便地觀看乾電池(7〇) 内的即時電容量以及所_壽命值#資訊,甚至可以直接將本創作加 載於市售充電裝置上’使原本充電裝置的功能升級為智慧我電震 置’因而不需另外購買含有此魏賴充電裝置,故可節省購置成 本。另一方面’在使用時’顯示單元(5〇)可以顯示乾電池⑽即時的 充、放電指數,乾電池(7〇)充飽電後則會自動立即斷電,並以警示裝 置(44)(如蜂鳴器)發出音頻來提醒使用者,同時可測得乾電池(7〇)所 剩的壽命值,當乾電池(7〇)壽命耗盡而不敷使用時,則會透過顯示單 元(50)建議使用者更換新的乾電池(7〇),藉以避免因乾電池(7〇)不當 的充放電所致的電能耗費以及危險情事的發生。 為因應各種可攜式電子設備充斥市面,而這些產品大多數都須仰 M406871 賴二次電池’所以二次電池市場已絲各家廠牌兵爭 名的大廠或是新起的品#,大部料費者對於 之地,無論是知 ^ .售的二次電池皆 -無所知。有鐘於此,本創作主要是讓消費者能夠自行對市售的二次 電池做祕的品質_,触舰至充钱置的檢測,細廣面不只 有-般的三號或四號電池,任何二次電池如手機、遙控車、電動車、 太陽能電池甚至目誠極發展_電混合車,任何_可在充電的二 次電池皆是本創作的應用範圍。V. New description: 【New technology field】 • This creation department is about a charger with battery life detection function, especially a charger with information such as charging and displaying battery instant capacity and life value. . [Prior Art] With the development and advancement of technology, various portable electronic products and devices have become more and more popular and have gradually become an indispensable important home appliance product in the public life. Moreover, the world is paying more and more attention to energy storage equipment. Among them, secondary batteries of rechargeable type have gradually become the mainstream in the market, but there are still many potential dangers and disadvantages of secondary batteries. As the usable capacity of the secondary battery decreases with the user's consumption and the number of times and times of charging and discharging, that is, the battery capacity will gradually decrease and have a life expectancy, thus causing consumers to have The limitation, plus the battery charger sold on the market can not show the battery capacity available, so that the actual use of the battery can not be known, so in the modernization of the secondary battery, the monitoring of battery quality and life is more important. Most of the general chargers only have the basic charging function, and the Led light display means that the charging capacity of the battery is high when charging >1, so that the correct charging capacity and internal wear of the battery during charging cannot be displayed. status. What's more, the charging method used in the common charging devices on the market is nothing more than the use of constant current charging, constant voltage charging or constant current constant voltage two-stage charging, pulse current charging, etc., just to minimize the impact on battery life. In the case of charging the battery to fully charge, there are other different functions, such as charging the M406871 vr with USB, automatically detecting the positive and negative charging, evaluating the battery charging capacity, etc., but still can not detect and interpret the rechargeable battery. Various chargers that use data and display. Generally, the capacitance of a battery will vary with the depth of discharge, that is, the capacitance of the battery will vary with the period of use, the number of hours, and the depth of discharge, and the residual capacity of the battery will vary with the age of the battery. It is different, so the residual capacity of the battery is difficult to estimate. The following is a description of the conventional battery capacity detection method: (1) Specific gravity: As shown in the reference [9] of Annex II, the specific gravity of the electrolyte is measured as the capacity. Detection. Since the concentration of the electrolyte is different when the battery is charged and discharged, the electrolyte concentration increases during the charging process, and the electrolyte concentration decreases during the discharge process. Therefore, the electrolyte concentration has a linear relationship with the state of charge, but the specific gravity is evenly distributed during the measurement, so The delay will cause an inaccurate measurement. This measurement method is commonly used in batteries used in automobiles and locomotives. (2) Open circuit voltage: As shown in the reference [9] of Annex II, after the battery is charged, its terminal voltage will gradually decrease with time. When the battery is discharged, its terminal voltage will rise slowly with time. As with the hydrometer method, it is necessary to wait for a long static stabilization time to be measured by this method. This measurement is common in mercury batteries. (3) Loaded voltage method: As shown in the reference [9] of Annex II, the battery capacity is estimated according to the load voltage value of the battery connected to the negative voltage. The method is suitable for the fixed load condition. Capacity 'is the method used by the most commonly used battery capacity M406871 in side operation. Therefore, as the load becomes larger or smaller, the indicated capacity also changes. This measurement is common in general batteries. (4) Coulometric measurement: As shown in the Annex II reference «-[9], the amount of current charged or discharged by the battery is measured to integrate the time to calculate the battery capacity. The integral of the discharge current and the discharge to the end voltage indicates the battery capacity Ah: • 4 = J. ίί〇 where ^(t) is the discharge current that changes with time, and k is the initial time of the discharge state. k is the final state of the discharge state. In the case of loading, it is a practical measurement method and is applicable to various batteries. However, the prerequisite for this method is that the existing capacity in the battery must be known in order to obtain a more accurate battery capacity. Common in current charging devices. According to the current knowledge, the representative patent case using the above open circuit voltage method is, for example, the domestic new patent No. M350170 "a dual-purpose charger capable of detecting the remaining capacity of the battery", as shown in the reference [7] of the φ component. And the new patent No. M389393 "energy-saving charger", these conventional structures are only compared with the measured voltage according to the reference voltage of the comparison circuit, and then the high and low potentials are output according to the comparison result, thereby driving the light-emitting light The polar body (LED) 'shows how much the battery capacity is lit by the number of LEDs lit. These conventional structures do not have a battery life calculation mechanism, so only the battery capacity can be roughly calculated. Since the estimated capacitance value is not accurate enough, no 5 M406871 method correctly displays the actual battery capacity. And the remaining life information of the battery, thereby misleading the user to judge the service life of the battery, resulting in improper electrical energy consumption and dangerous situations caused by improper charging and discharging of the battery, thereby causing inconvenience and trouble in charging use, so The conventional structure does have the necessity of further improvement. Another conventional structure, such as the domestic invention No. 12759573 "Battery charging method for detecting the rated capacity of the battery and determining the charging current according to the rated capacity of the battery", is a battery rated capacity detecting device and method for knowing The rated capacity of the battery, and according to its rated capacity, calculate the most suitable charging current value to charge the battery, and charge according to different rated capacity batteries with different charging currents, so that the batteries with different rated capacities can reach the best. The charging effect. Although the conventional structure can detect the rated capacity of the battery, and then charge the battery with a suitable charging current, the conventional structure does not have a computing mechanism for the display unit and the battery life, so the conventional structure cannot be detected and displayed. Information such as the actual capacity of the battery and the service life of the battery, which may easily mislead the user to judge the battery life, resulting in improper electrical energy consumption and dangerous situations caused by improper charging and discharging of the battery, thus causing inconvenience in charging use. And the troubles, so the use of such a structure is broken and there is a need for further improvement. Another related conventional structure, such as the "Battery Pack" of the National Invention No. 465133, which can determine the loss of the battery function state, and controls the charge and discharge and the forced discharge, and has a charge and discharge control mechanism. The battery is charged and discharged; the forced discharge control 6 M406871 mechanism is to force the discharge of each unit; the function detection mechanism is used to detect the functional status of the battery pack; the determination mechanism 4, 5 is determined by the function detection mechanism The function of the function H; and the control of the woman's wife (four) the determination of the loss of the functional state obtained by the bullying agency 'has selected the slaves on the lake (4) and the strong electricity (four) face. The conventional structure has the function of determining the function loss of the battery life, and can perform the charging and discharging control according to the determination, and the battery can be safely used. However, the life calculation mechanism is The use of the battery, the number of hours of use, the number of charge and discharge contacts and the sound of the wire, etc., so the judgment of the battery life of the uniform structure is only a rough estimate, because the battery life value is not accurate enough, so only It can be used as a reference for battery use, and its overall structure is very complicated, which leads to a manufacturing cost that is too expensive to be widely used. Moreover, the battery pack of the conventional structure has no display unit and can only be transmitted to the communication device. The remote computer is used to view the parameters of the battery, which causes inconvenience and great trouble in charging. The reason is that 'there is a lack of the above-mentioned conventional structure. Therefore, the creator is actively working on the research. After development, I finally developed a kind of creative work. [New content] This is the first creation. The purpose is to provide a battery life detecting function charger, which mainly has the functions of battery performance display, charge and discharge index display, instant charge and discharge current display and automatic power off, etc., which can not only detect and display the battery capacity and service life of the battery. 7 M406871 k, to quickly verify whether the battery is good, whether the actual capacitance is consistent with the marked value, and can further understand the internal loss of the battery and whether the charging and discharging action is normal, so you can do instant on all types of rechargeable batteries. Check and strict monitoring, thus saving energy, avoiding the purchase of poor quality batteries, and avoiding the dangerous situation caused by improper battery charging and discharging. In order to achieve the above effects, the technical means adopted by the present invention includes a first pedestal, a signal extraction unit, an operation means, a display unit and a charging control circuit, and a battery is disposed on one side of the first pedestal. a first placement slot, the first placement slot is provided with at least one pair of first electrode groups electrically connected to the battery, and the first base is disposed to be electrically connected to the first electrode group The signal tracing unit is configured to sense a current or a voltage state of the battery being charged to generate a sensing signal, and the computing device converts the sensing signal into a charging and discharging index value corresponding to the instantaneous capacity of the battery and a The life value, the display unit displays the charge and discharge index value as the charge and discharge index information, and the charge control circuit can be controlled by the operation means to control the charging timing of the battery. The second object of the present invention is to provide a charger with a battery life detecting function that can be directly combined with any commercially available charging device, so that the function of the original charger can be upgraded to a smart charging device, so that no additional need is needed. Purchase to save on acquisition costs.
