Description of the Invention: [Technical Field] The present invention relates to a battery, and more particularly to a monitoring method for monitoring the life of a lithium battery. [Prior Art] Nowadays, with the popularization of portable electronic products, the demand for rechargeable batteries has been relatively driven, and driven by these demands, in order to make portable electronic products suitable for users for a long time. Under the demand, the sustainability and longevity of rechargeable batteries have become an important key for battery applications. For rechargeable batteries, the reliability of battery power and battery health monitoring has been listed as one of the important topics. At present, the monitoring of rechargeable batteries is divided into two items, one is the battery's electrical state, which means The battery's state of charge, and the other is the health of the battery, it is used to show the aging of the battery; fine, the current battery design is focused on the monitoring of battery storage cancer, but affects the battery life There is very little aging monitoring, which makes it impossible to actually grasp the true life of the battery.
目前所常見的充電電池監控方式，特別是針對鐘電池，對於電池狀態 的監測幾乎都使用電池電壓作為參數，如電壓監測、容量計算、電解液密 度皿測、内阻$測、交流阻抗儀(AC imped·)監測等方式估算電池的狀 態；然而，綜觀這些電池的監測方式，如電壓監測，雖為最簡單的狀況， 雜賴信極低，無法真正反應電池的可用容量，且無法經由電池電壓詳細 付知電池的老化狀態，舉链電池為例，當電池的可用容量僅剩下原來的 咖，但是電池之電壓在充飽電時仍可達到4.2V，但是該電池已經無法承受 =電流放電’-經放電’電壓即下降至3V以下，根本與電池真實情況不相 “另外，容量計算咖在筆記型電腦之電量預估上，但電池容繼⑸ 3 201215904 機情況下，會有極小的紐導《池自放電，且該麵是無法量測的，在 使用-段時間之後會有累積性的誤差，造成精確度會受到限制，同時此方 法須使用較複雜之電路⑽’成本較高；而其他所舉的如電解液密度監測、 内阻量測、交流阻抗儀(AC琴d纖）監測方式皆都有使用到較複雜之電 路系統及成本高’或根本不適用於經電池等類似的缺點存在。 雖然後續的技術中，如台灣專利公開號第2〇〇94283〇號經電持危險狀 態預警方法及記錄媒體，其技術係記錄㈣池的電壓粍電量關係曲線後， *再進行取得在一定時間内所產生的第一電壓值及第二電壓值，最後在找出 及記錄運作狀態下其電流所相對應的電壓耗電量關係值，並依據第一電壓 值及第二電壓值範财’以械應的電壓耗電量_顧出電池危險警訊 的警戒值’如此進行比對後來進行對链電池的情況進行監控；然而此透過 監測電壓的方式，仍舊未考量到經電池在進行放電時的二^；目變化，於二 元相變化中Μ不會改變的特性，針對電壓的監測方式，是無法真實 呈現電池的壽命及老化問題的。 藝由社之·即可知道，若單純監測t池驗但未考量到電池的老化 情況，將會誤判電池的狀態。 【發明内容】 本發明的目的就是在提供-種鐘電池壽命狀態之監測方法，係針對鐘 鐵電池的放電極化曲線’來提前發現不良之链電池，藉由保護整體電池組 之壽命。 為達成上述之目的，本發明係提供一種鋰電池壽命狀態之監測方法， 201215904 係經由記_電池於無負載時之電壓與電容之_數據，之後再記雜電 池單位時隨冑繩輪嫌辑，#物綱數據經由— 異常之警訊 /5白微刀後之數據力析後產生1係圖，在持續監測電池的過財，若其關 係圖之曲線產生異輕化’即代表電池_產生賤，藉此提出電池出現 為讓本發明之上述和其他目的、特徵和優點能更明顯易懂，下文特舉 較佳實施例’並配合所關式，作詳細說明如下。 • 【實施方式】 茲將本發明之内容配合圖式來加以說明： 請參閱第-圖，係為本發明之結構方塊圖。如圖所示，本發明之監測 方法係針對賴電池進行監測，圖中係主要包括一承載單元i，用以置放待 測鐘電池，該承載單元丨之—端並銜接—貞載以進行電力輸出，而該承載 早元1内部設有-控制單元η ’用以控制數據輸出，該承載單元i又電性 連接-記錄單兀2 ’用以接收該承載單元丨之電池監測數據及分析，另，該 籲承載單元1另連接-充電控制單元3，控制其充放電之情況，該充電控制單 元3最後再電性連接一充電器4，以提出電力之輸入。 請參閱第二圖至第五圖，係分別為本發明之無負載時其電壓與電容之 關係曲線、lc放電電容與電壓之關係曲線圖、一階微分數據正常圖及一階 微分數據不良圖。如第二圖所示，首先先透過記錄單元2先行記錄該鋰鐵 電池於無負載時其電壓與電容之關係曲線，於本實施例中該曲線係保持在 3V〜3. 5V之間，即為電池放電時之正常電壓；需參閱第三圖’而紀錄單元2 再針對該待測之電池進行於lc放電時電壓與電容之曲線關係圖，其中此所 5 201215904 提之lc定義為電池於一小時内放可放完之電流量，除此之外，此記錄方式 也可以應用於複數電池之管理及統計，之後則再利用第二圖及第三圖所產 生之數據進行一階微分，其計算方式為（無負載電壓（v〇) _lc玫電時電壓 (VI)) /放電電流*l〇〇〇=mohm，其產生之統計數據及形成第四圖，在正常 之電容與mohm之關係曲線圖，因此，透過圖一之記錄單元2進行單—或複 數之簡電池之監測，若電池在放電中之過程中其數據經—階微分所產生 之關係曲線圖如第四圖一般，代表其電池之狀態良好；反之，若其一階微 • 分所產生之關係曲線圖如第五圖時，代表其電池内部之產生異常’如鋰金 屬析出、極板剝落或電解液變質等問題出現，代表被監測之電池產生老化 現象，有助於進行更換電池。 請參閱第六圖’係為本發明方法流程圖。係將前述之操作流程以—方 法流程圖表不之’如圖所示，記錄一鍾電池於無負載時其電壓與電容之關 係數據（S1)’記錄該链電池於ic放電時電壓與電容之數據，並與該無負 載時其電壓與電容之關係數據整合進行一階微分計算產生一關係曲線 # (S2) ’持續於单位時間内重複記錄前述數據，並比對前述之關係曲線，以 判斷是否有異常出現（S3) 〇 惟以上所述之實施方^，是為較佳之實施㈣，當不能以此限定本發 明實施ί— ’若依本發明中料利範圍及說明書内容所作之等效變化或修 飾’皆應屬本發明下述之專利涵蓋範圍。 201215904 【圖式簡單說明】 第一圖、係為本發明之結構方塊圖。 第一圖、係為本發明之無負載時其電壓與電容之關係曲線圖。 第二圖、係為本發明之1(：放電電容與電壓之關係曲線圖。 第四圖、係為本發明之—階微分數據正常圖。 第五圖、係為本發日月之_階微分數據不良圖。 第六圖、係為本發明之方法流程® (S1)〜（S3)。 【主要元件符號說明】 承載單元1 控制單元11 記錄單元2 充電控制單元3 充電器4At present, the common monitoring methods of rechargeable batteries, especially for clock batteries, almost always use battery voltage as a parameter for battery status monitoring, such as voltage monitoring, capacity calculation, electrolyte density meter measurement, internal resistance $ measurement, AC impedance meter ( AC imped·) monitoring and other methods to estimate the state of the battery; however, looking at the monitoring methods of these batteries, such as voltage monitoring, although the simplest situation, the noise is very low, can not really reflect the available capacity of the battery, and can not pass the battery The voltage details the aging state of the battery. For example, when the battery is available, only the original coffee is left, but the voltage of the battery can still reach 4.2V when fully charged, but the battery can no longer bear = current discharge. The '-discharge' voltage drops below 3V, which is completely different from the actual situation of the battery. In addition, the capacity calculation is based on the power estimation of the notebook computer, but the battery capacity is (5) 3 201215904, there will be very small New Guide "The pool is self-discharged, and the surface is unmeasurable. There will be cumulative errors after the use period, resulting in accuracy. To the limit, this method must use a more complicated circuit (10) 'higher cost; and other methods such as electrolyte density monitoring, internal resistance measurement, AC impedance meter (AC violin) monitoring are used More complicated circuit systems and high cost 'or not suitable for similar shortcomings such as batteries. Although the following technologies, such as Taiwan Patent Publication No. 2, 942, 833, the dangerous state warning method and recording media After the technical system records (4) the voltage and electricity relationship curve of the pool, * the first voltage value and the second voltage value generated in a certain period of time are obtained, and finally the current corresponding to the operating state is found and recorded. The value of the voltage power consumption relationship, and according to the first voltage value and the second voltage value Fancai 'the power consumption of the device should be _ take care of the battery hazard warning value' The situation is monitored; however, by monitoring the voltage, there is still no consideration of the characteristics of the battery when it is being discharged, and the characteristics of the binary phase change will not change. The monitoring method of pressure is unable to truly represent the life and aging of the battery. It can be known from the art of the company that if the t-cell test is simply monitored but the aging of the battery is not considered, the state of the battery will be misjudged. The purpose of the present invention is to provide a method for monitoring the battery life state of a clock, and to detect a defective chain battery in advance for the discharge polarization curve of the clock iron battery, by protecting the life of the entire battery pack. The purpose of the present invention is to provide a method for monitoring the life state of a lithium battery, 201215904 is based on the voltage and capacitance of the battery when no load is used, and then the battery unit is counted with the reel pulley. The data is generated after the data of the abnormality alarm/5 white micro-knife, and the 1 series is generated, and the battery is continuously monitored. If the curve of the relationship diagram is different, it means that the battery is generated.
