In an embodiment, the main device is a physiological monitoring device, and can be coupled to the living organism to be tested via the input terminal and the input terminal In2 to measure the physiological signal of the living organism to be tested, for example, electrocardiography (ECG). Wait. Furthermore, the operating voltage of the main device wo is provided by the battery module 240, and the number of diodes in the diode string 22 is determined by the battery module 240. In an embodiment of the invention, the battery module 240 and the main unit 25 are sealed in the housing of the module 23 to be charged. 3 shows a battery module 300 according to an embodiment of the invention. The battery module 300 includes a rechargeable battery 31A and four diodes D2-D5, wherein the positive pole of the rechargeable battery 310 (by symbol "+, And the negative electrode (indicated by a symbol) are respectively coupled to the operating voltage VDD of the main device 25A and the ground terminal VSS. The diode D2 is coupled from the input terminal In to the rechargeable battery 31 in the forward direction. The anode of the rechargeable battery 310 is coupled from the negative terminal of the rechargeable battery 310 to the input terminal Inr diode D4 in the forward direction from the input terminal In2 to the positive electrode of the rechargeable battery 310. The diode 〇 5 is coupled from the negative pole of the rechargeable battery 310 to the input terminal In2 in a forward direction.

在一實施例中’待充電模組230為量測心電圖的模 組’其中電池模組240為無極性電池模組（即第3圖中的 電池模組300)。在待充電模組230中，輸入端Ιηι以及輸 入端Ins係由導電材料所組成的電極。在此實施例中，待 充電模組230可透過電極來量測心電圖，亦可透過電極來 對鋰電池進行充電。充電電路210包括充電晶片，用以在 輸出端Out丨以及輸出端〇ut2之間提供大體上為42伏特的 電位差（即電位差Δνι = 4.2ν)，其中輸出端〇叫的電位 大於輸出端Ouk的電位。此外，為了能達到等電位充電， 二極體串220係由兩個二極體（D"、D〗2)所組成，用以 對應於電池模組300中的二極體D2、D5或是二極體D3、 D4。一般而言，二極體的導通電壓為〇·7伏特。因此，在 此實施例中，輸出端Ouk以及輸出端Ouk之間具有丨4伏 =電位差（即電位差^叶〜），其中輸出端〇叫 的電位大於輸出端0ut3的電位。再者，如前文所描述，待 ，電棋組230内的電池模組為無極性電池模組。因此， ST:二雖然輸出端⑽1的電位大於輸出端⑽3 1充電模組23〇的輸入端Ιηι以及輸入端％可任 接於輸出端⑽1以及輸出端㈣。例如，當輸入端Ιηι 〇963-A22220TWF(N2)；P27960014TW；nikey 10 1338425 耗接至輸出端Out!時，輸入端In2則搞接至輸出端〇ut3。 反之，當輸入端In!耦接至輸出端Out3時，輸入端In2則耦 接至輸出端Out!。因此，待充電模組230不需要設計額外 的防呆裝置來避免充電過程中接點極性的問題。再者，本 發明所描述的充電裝置可適用於各種類型的鋰電池。 除了不受極性的限制之外，待充電模組中電池模組所 使用的二極體（例如：第3圖中的二極體D2-D5)亦可提 供限流的功能，以防止充電初期的大電流灌入而造成電池 的損害。再者，當靜電放電（Electrostatic Discharge，ESD ) 能量經由輸入端In!以及輸入端In2進入待充電模組時，電 池模組内的二極體可迅速將ESD能量導入充電電池内，以 避免損害生理監控裝置内的元件而影響量測的準確度。 第4圖係顯示根據本發明另一實施例所述之電池模組 400。電池模組400包括充電電池410以及四個二極體串 420-450，其中二極體串420-450各包括至少一二極體。如 第4圖所顯示，二極體串420包括二極體D21、D22，而二 極體串430包括二極體D31。二極體串440包括二極體D41、 D42，而二極體串450包括二極體D51。值得注意的是，二 極體串420内的二極體數量相同於二極體串440内的二極 體數量，而二極體串430内的二極體數量相同於二極體串 450内的二極體數量。再者，為了達到等電位充電，二極 體串420以及二極體串430内之二極體的數量總和相同於 第2圖中二極體串220内二極體的數量。因此，如第4圖 所顯示，可得知二極體串220具有三個二極體。此外，電 0963~A22220TWF(N2)；P27960014TW；nikey 1338425In one embodiment, the module to be charged 230 is a module for measuring an electrocardiogram, wherein the battery module 240 is a non-polar battery module (i.e., the battery module 300 in FIG. 3). In the module to be charged 230, the input terminal 以及ηι and the input terminal Ins are electrodes composed of a conductive material. In this embodiment, the charging module 230 can measure the electrocardiogram through the electrodes, and can also charge the lithium battery through the electrodes. The charging circuit 210 includes a charging chip for providing a potential difference of substantially 42 volts between the output terminal Out and the output terminal 〇ut2 (ie, a potential difference Δνι = 4.2 ν), wherein the potential of the output terminal is greater than that of the output terminal Ouk. Potential. In addition, in order to achieve equipotential charging, the diode string 220 is composed of two diodes (D", D2) for corresponding to the diodes D2, D5 in the battery module 300 or Diodes D3, D4. In general, the on-voltage of the diode is 〇7 volts. Therefore, in this embodiment, the output terminal Ouk and the output terminal Ouk have a potential difference of 丨4 volts (i.e., potential difference 叶~), wherein the potential of the output terminal squeak is greater than the potential of the output terminal ut3. Furthermore, as described above, the battery module in the electric chess set 230 is a non-polar battery module. Therefore, although the potential of the output terminal (10)1 is larger than the output terminal (10), the input terminal Ιηι of the charging module 23A and the input terminal % can be connected to the output terminal (10) 1 and the output terminal (4). For example, when the input terminal Ιηι 〇963-A22220TWF(N2); P27960014TW; nikey 10 1338425 is consumed to the output terminal Out!, the input terminal In2 is connected to the output terminal 〇ut3. On the other hand, when the input terminal In! is coupled to the output terminal Out3, the input terminal In2 is coupled to the output terminal Out!. Therefore, the module to be charged 230 does not need to design an additional foolproof device to avoid the problem of contact polarity during charging. Furthermore, the charging device described in the present invention can be applied to various types of lithium batteries. In addition to being unrestricted by polarity, the diode used in the battery module in the module to be charged (for example, the diode D2-D5 in Fig. 3) can also provide a current limiting function to prevent initial charging. The high current is injected and the battery is damaged. Furthermore, when Electrostatic Discharge (ESD) energy enters the module to be charged via the input terminal In! and the input terminal In2, the diode in the battery module can quickly introduce ESD energy into the rechargeable battery to avoid damage. Physiological monitoring of components within the device affects the accuracy of the measurement. Fig. 4 is a view showing a battery module 400 according to another embodiment of the present invention. The battery module 400 includes a rechargeable battery 410 and four diode strings 420-450, wherein the diode strings 420-450 each include at least one diode. As shown in Fig. 4, the diode string 420 includes diodes D21, D22, and the diode string 430 includes a diode D31. The diode string 440 includes diodes D41, D42, and the diode string 450 includes a diode D51. It should be noted that the number of diodes in the diode string 420 is the same as the number of diodes in the diode string 440, and the number of diodes in the diode string 430 is the same as in the diode string 450. The number of diodes. Furthermore, in order to achieve equipotential charging, the sum of the number of diodes in the diode string 420 and the diode string 430 is the same as the number of diodes in the diode string 220 in Fig. 2. Therefore, as shown in Fig. 4, it can be seen that the diode string 220 has three diodes. In addition, electricity 0963~A22220TWF(N2); P27960014TW; nikey 1338425
