Description
本發明係有關於一種具有殘量顯示之蓄電池，尤指一種於蓄電池內一體組裝一單晶片電池殘量檢測模組，利用該設計簡便之單晶片電池殘量檢測模組，以運算蓄電池於供予機件作動之電力損失外，更進一步運算溫度與時間等因素造成蓄電池自行放電之損耗，而獲得精準的電能殘量值。The invention relates to a battery with a residual display, in particular to a single-wafer battery residual detection module integrally assembled in a battery, and the single-chip battery residual detection module is conveniently used to calculate the battery for use. In addition to the power loss caused by the machine, the temperature and time are further calculated to cause the loss of the battery self-discharge, and the accurate residual value of the electric energy is obtained.
按，蓄電池的使用在日常生活中是常見的，由手機、手提電腦、攝影機，乃至汽、機車上，可供充電再利用的蓄電池都是不可或缺的能量來源。
而現今大多蓄電池皆設有殘量顯示之裝置，以供使用者隨時得知蓄電池的的剩餘電量，在蓄電池電力不足時，可以適時為蓄電池進行充電。
現有的檢測蓄電池殘量的方式，係包含有比重法、負載電壓法及庫倫量測法，但上述方法或有難以準確估測殘電量，或量測步驟繁瑣，限制多等缺失，並且其殘量顯示裝置多與蓄電池分開設置，而造成實施上極多的不便利性。
請參閱我國公告第200832783號之「鉛酸蓄電池殘電量估測系統與方法」，係適用於程式化建立在一電子設備上，估測系統之統計單元可供輸入鉛酸蓄電池在多數不同負載條件下的殘電量與相對應內阻値，而建立殘電量與內阻中位數値之相對關係的統計資料組。估測系統之曲線擬合單元可由統計資料組分析出一由內阻値與殘電量構成之最佳擬合方程式。估測系統之整合運算單元可依據所接收之鉛酸蓄電池內阻値，而由擬合方程式分析出相對應殘電量及可供電時間。透過以內阻中位數値與殘電量所構成之統計資料組為基礎，可使建立之擬合方程式更準確地估測出鉛酸蓄電池之殘電量與可供電時間。
另我國公告第200832783號之「鉛酸蓄電池殘電量估測系統與方法」，係主要程式化建立在一電子設備上，估測系統供輸入鉛酸蓄電池在多數不同負載條件下的殘電量與相對應內阻值，而建立殘電量與內阻中位數值之相對關係的統計資料組，而此系統為一龐大外掛系統，對於一般使用者操作上過於複雜，必須透過此設備才可量測電池殘量，此為其一缺失；
再者，蓄電池每顆的充放電特性曲線都不盡相同，並且經過多次充放電之後，其特性也會飄移，而該現有的我國公告第200832783號之「鉛酸蓄電池殘電量估測系統與方法」，係無法因應蓄電池充放電後之誤差而做修正，以求得最精準的電壓值，此為其二缺失；
另者，該電子設備多須配合建設於一如計算機或行車電腦等電子裝備上，依此，當欲將此鉛酸蓄電池殘電量估測系統組裝於機體上時，便須於機體上預先設置可供組裝電子裝備與鉛酸蓄電池之處，如：汽車於出廠前，便預先將此電子裝備建置於行車電腦中，因此，對於一般消費者而言，係無法自行購買組裝及維修，並且亦無法直接由蓄電池上觀察得知其電力剩餘狀況，導致當對蓄電池充電時，使用者不能準確由蓄電池上直接得知充電狀態，為其三缺失。
緣是，本發明者有鑑於現有鉛酸蓄電池殘電量估測系統於設計上諸多缺失，乃藉其多年於相關領域的製造及設計經驗和知識的輔佐，並經多方巧思，針對該蓄電池殘量檢測作更新的研發改良，以期發揮其更高的實用效益性。
According to the use of batteries, it is common in daily life. From mobile phones, laptops, cameras, and even steam and locomotives, batteries that can be recharged and reused are indispensable sources of energy.
Most of the batteries today are equipped with a residual display device for the user to know the remaining battery capacity at any time. When the battery power is insufficient, the battery can be charged at the right time.
The existing methods for detecting the residual amount of the battery include a specific gravity method, a load voltage method, and a Coulomb measurement method, but the above method may have difficulty in accurately estimating the residual power, or the measurement step is cumbersome, the limitation is excessive, and the residue is The quantity display device is often disposed separately from the battery, resulting in an extremely inconvenient implementation.
Please refer to the "System and Method for Estimating the Residual Capacity of Lead-Acid Battery" in China's Announcement No. 200832783, which is suitable for stylized establishment on an electronic device. The statistical unit of the estimation system can be used to input lead-acid batteries under most different load conditions. The residual power and the corresponding internal resistance, and the statistical data group that establishes the relative relationship between the residual electricity and the median 内 of the internal resistance. The curve fitting unit of the estimation system can be analyzed by the statistical data group to form a best fitting equation composed of internal resistance and residual electricity. The integrated computing unit of the estimation system can analyze the corresponding residual power and the power supply time according to the fitting equation according to the internal resistance of the lead-acid battery received. Based on the statistical data set consisting of the median 値 and residual capacity of the internal resistance, the established fitting equation can more accurately estimate the residual capacity and power supply time of the lead-acid battery.
In addition, China's Announcement No. 200832783 "Estimation System and Method for Residual Electricity of Lead-Acid Battery" is mainly programmed on an electronic device to estimate the residual power and phase of the input lead-acid battery under most different load conditions. Corresponding to the internal resistance value, and establishing a statistical data group of the relative relationship between the residual power and the median value of the internal resistance, and the system is a huge external system, which is too complicated for the general user to operate, and the battery must be measured through the device. Residual amount, this is a missing;
Moreover, the charge-discharge characteristic curve of each battery is different, and after a plurality of charge and discharge, its characteristics will also drift, and the existing China National Publication No. 200832783 "the lead-acid battery residual capacity estimation system and The method cannot be corrected according to the error after the battery is charged and discharged, in order to obtain the most accurate voltage value, which is the second missing;
In addition, the electronic device must be built on an electronic device such as a computer or a traveling computer. Accordingly, when the lead-acid battery residual capacity estimation system is to be assembled on the body, it must be pre-set on the body. It can be used to assemble electronic equipment and lead-acid batteries. For example, before the car leaves the factory, the electronic equipment is built into the driving computer in advance. Therefore, for the average consumer, it is impossible to purchase the assembly and repair by itself. It is also impossible to directly observe the remaining state of the power from the battery, so that when the battery is charged, the user cannot accurately know the state of charge directly from the battery, and the three are missing.
Therefore, the inventors have in view of the many design flaws in the existing lead-acid battery residual capacity estimation system, and have relied on many years of manufacturing and design experience and knowledge in related fields, and have been ingeniously thinking about the battery residue. The quantity detection is updated and researched and improved in order to exert its higher practical efficiency.

為了達到上述實施目的，本創作乃研擬如下具有殘量顯示之蓄電池，係主要於蓄電池內一體組裝一單晶片電池殘量檢測模組，而於該單晶片電池殘量檢測模組內係包含一蓄電池耗電偵測單元、一溫度感測單元及一計時單元，並使該蓄電池耗電偵測單元、溫度感測單元及計時單元與一單晶片相連接，並於該單晶片內載錄有溫度與蓄電池自行放電之對照資料及時間與蓄電池自行放電的對照資料，復使該單晶片與一顯示單元相接設。
藉此，將蓄電池供予機件作動之電能損失與溫度與使用時間等因素所造成蓄電池自行放電之電能損耗加總後，再與蓄電池上一時點之所得之電量相減，即可獲得精準的電能殘量值，並顯示於顯示單元上，以達到正確告知使用者目前電池剩餘電量之效果。
