Description
本發明係關於充電方法，尤指一種供電裝置在對行動終端裝置進行充電的過程中，其停止供電一預定時間，且在前述時間內偵測行動終端裝置之充電電池的當前電壓，以調整後續供電電流的充電方法。 The present invention relates to a charging method, and more particularly to a power supply device that stops power supply for a predetermined period of time during charging of a mobile terminal device, and detects a current voltage of a rechargeable battery of the mobile terminal device within the aforementioned time to adjust subsequent The charging method of the supply current.
近年來，隨著電子及通訊技術的蓬勃發展，行動終端裝置(如：行動電話(mobile phone)及智慧電話(smart phone)...等)幾乎已成為大多數都會人不可或缺之一重要裝置，人手一機亦成為都會區隨處可見之普遍景象，因此，在人們對行動終端裝置越來越依賴的情況下，行動終端裝置的「續航力」(即，在不充電的情況下，所能持續運作的時間)儼然成為人們所重視之處。 In recent years, with the rapid development of electronic and communication technologies, mobile terminal devices (such as mobile phones and smart phones, etc.) have become an indispensable part of most metropolitans. The device and the human hand have become a common sight everywhere in the metropolitan area. Therefore, in the case where people are increasingly relying on mobile terminal devices, the "end-of-life" of the mobile terminal device (that is, in the case of no charging, The time of continuous operation has become a place of attention.
承上，影響行動終端裝置「續航力」的原因眾多，但主要因素包括了：一是耗電的電子零件，例如：愈來愈大的手機螢幕、功能更強大之系統晶片(System on Chip，簡稱SoC)；二是更快速的無線網路技術，例如：4G技術遠較3G技術更為耗電；三是更多的附加功能與背景程式，例如：藍牙(B1uetooth)搜尋、GPS定位、即時通訊軟體(如：LINE)...等，造成業者的節電技術實無法追上耗電的步伐，導致諸多行動終端裝置之電池所提供之電力，並不足以供行動終端裝置一天使用，故，為避免行動終端裝置因電力不足而無法使用之窘境，人們在外出時，通常會攜帶行動電源，以能 對行動終端裝置進行充電，保持該行動終端裝置之「續航力」。 There are many reasons for affecting the endurance of mobile terminal devices, but the main factors include: First, power-consuming electronic components, such as: ever-increasing mobile phone screens, more powerful system chips (System on Chip, referred to as SoC); Second, faster wireless network technology, for example: 4G technology is far more power-hungry than 3G technology; third is more additional features and background programs, such as: Bluetooth (B1uetooth) search, GPS positioning, instant messaging Software (such as: LINE), etc., the industry's power-saving technology can not catch up with the pace of power consumption, resulting in the power provided by the battery of many mobile terminal devices, not enough for the mobile terminal device to use one day, so Avoid the dilemma that mobile terminal devices cannot be used due to insufficient power. When people go out, they usually carry mobile power to enable The mobile terminal device is charged to maintain the "end of force" of the mobile terminal device.
茲就現有行動終端裝置與供電裝置(如：行動電源)間充電技術，進行說明，請參閱第1圖所示，為避免圖式過於複雜，僅在第1圖中繪示出行動終端裝置之部分元件，又，該行動終端裝置1包括該充電電池11、一般充電電路13及一傳輸埠15，其中，該充電電池11係與該一般充電電路13相電氣連接，且該一般充電電路13能與該傳輸埠15相電氣連接，以能由該傳輸埠15中接收來自一供電裝置19的電流，並傳送至充電電池11，又，該一般充電電路13上設有一電池充電晶片130(Battery Charger IC)，該電池充電晶片130主要能提供充電電池11所需之正確充電電流及充電電壓，意即，該電池充電晶片130會量測充電電池11之充電電流與電壓，以使該充電電流與電壓保持在業者的預定範圍內。 For the description of the charging technology between the existing mobile terminal device and the power supply device (such as mobile power), please refer to FIG. 1 . To avoid the complexity of the drawing, only the mobile terminal device is shown in FIG. 1 . In some embodiments, the mobile terminal device 1 includes the rechargeable battery 11, the general charging circuit 13, and a transmission port 15, wherein the rechargeable battery 11 is electrically connected to the general charging circuit 13, and the general charging circuit 13 can The charging port 15 is electrically connected to receive the current from a power supply device 19 and transmitted to the rechargeable battery 11. Further, the general charging circuit 13 is provided with a battery charging chip 130 (Battery Charger) IC), the battery charging chip 130 can mainly provide the correct charging current and charging voltage required for the rechargeable battery 11, that is, the battery charging chip 130 measures the charging current and voltage of the rechargeable battery 11 so that the charging current and the charging current The voltage remains within the predetermined range of the operator.
另，為能縮短行動終端裝置之充電電池的充電時間，諸多業者紛紛設計出各種「快充技術」，在此特別一提者，所謂「快充技術」的基本理念，即是在充電電池所能負荷的範圍內，給予大電流，以達到短時間內使充電電池飽和的效果，然而，申請人發現，復請參閱第1圖所示，現有的充電方式中，供電裝置所提供之電流，均需透過該電池充電晶片130，才能將電流傳送至充電電池11，造成充電效率不彰，無法發揮出業者預期之「快充技術」的功效；此外，現有的「快充技術」在應用上，尚會面臨下列問題：(1)當充電電池11接收到電流時，其內部之電解液除了將電能轉換成化學能之外，尚會有部分電能轉換成熱量且散逸出來，造成充電電池11的溫度上升，因此，當電流愈大時，充電電池11所產生之熱量會愈多，進而縮 短充電電池11之使用壽命；及(2)當充電電池11之電壓趨近於飽和時，若持續接收到大電流，將會造成該充電電池11受到損害，令該充電電池11無法使用，或縮短其使用壽命。 In addition, in order to shorten the charging time of the rechargeable battery of the mobile terminal device, many manufacturers have designed various "fast charging technologies". In particular, the basic concept of the "fast charging technology" is in the rechargeable battery. In the range of load, a large current is given to achieve the effect of saturating the rechargeable battery in a short period of time. However, the applicant has found that, as shown in Fig. 1, the current supplied by the power supply device in the existing charging mode, It is necessary to charge the chip 130 through the battery in order to transfer the current to the rechargeable battery 11, which results in inefficient charging and fails to perform the "fast charging technology" expected by the practitioner; in addition, the existing "fast charging technology" is applied. The following problems will still be faced: (1) When the rechargeable battery 11 receives the current, in addition to converting the electrical energy into chemical energy, the internal electrolyte will be converted into heat and dissipated, resulting in the rechargeable battery 11 The temperature rises, so when the current is larger, the amount of heat generated by the rechargeable battery 11 will increase. The service life of the short rechargeable battery 11; and (2) when the voltage of the rechargeable battery 11 approaches saturation, if the continuous receiving of a large current continues, the rechargeable battery 11 is damaged, making the rechargeable battery 11 unusable, or Shorten its service life.
綜上所述可知，現有充電的相關技術，並無法確實滿足使用者的需求，甚至會對充電電池造成不良影響，故，如何有效解決前述問題，即成為本發明在此亟欲達成之重要課題。 In summary, the related technologies of the existing charging cannot meet the needs of the user and may even adversely affect the rechargeable battery. Therefore, how to effectively solve the above problem becomes an important issue for the present invention. .

The memory unit 33 and the power unit 34 are electrically connected to access the data in the memory unit 33, and control the power unit 34 to output a current to the charging port 31, and receive the data from the charging port 31. The data, however, is specifically mentioned herein. In FIG. 2, although the electrical unit 34 and the charging port 31 are electrically connected, in other embodiments of the present invention, the data is electrically connected. The unit 34 may not be electrically connected to the charging port 31, but may transmit current through the control unit 32. Therefore, in the scope of the subsequent embodiments or the patent application of the present invention, the "control unit 32 transmits current value" is claimed. Scope should include "control The control unit 32 of the power unit 34 is directly transmitting current to the charging port 31 "and" the control unit 34 receives power transmission unit 32 The current is sent, and it is transferred to the charging 埠31" and other implementations.

The charging comparison table 331 includes a plurality of voltage values and corresponding charging current values, and the power unit 34 can supply a charging current to the charging unit. The charging port 31, when the power supply device 3 is to perform a "fast charging technology" on the mobile terminal device 2, the fast charging switching chip 25 is switched to the fast charging mode so that the power supply device 3 can pass through the fast charging circuit 24, The rechargeable battery 22 is charged. Further, in the foregoing case, the control unit 32 transmits a first charging current value (eg, 2.1 amps) to the rechargeable battery 22, and during a continuous charging period (eg, 100 milliseconds). After (ms)), the control unit 32 interrupts the transmission of the first current value for an interruption period (eg, 100 milliseconds (ms)). At this time, the control unit 32 detects during the interruption period. The current voltage value of the power supply pin 311 of the charging port 31 can further know the current voltage value of the rechargeable battery 22, and the control unit 32 reads from the charging comparison table 331 according to the current voltage value. Corresponding to one of the second charging current values And after the end of the interruption period, the second charging current value (eg, 2 amps) is transmitted to the rechargeable battery 22, and continues for the charging period (eg, 100 milliseconds (ms)), after which the control unit 32 The second current value is again interrupted and continues for the interruption period (eg, 100 milliseconds (ms)), and during the interruption period, the current voltage value of the power supply pin 311 is detected, and the power is adjusted accordingly. The charging current output by the unit 34 until the voltage of the rechargeable battery 22 is saturated; here, when the rechargeable battery 22 no longer receives the current, the voltage value thereof changes to its own voltage value, therefore, the The control unit 32 can determine whether the voltage of the rechargeable battery 22 is saturated or close to saturation according to the current voltage value of the power supply pin 311, so as to adjust the charging current. Continuous transmission of large currents causes damage to the rechargeable battery 22.
