使用時,首先調節第二固持件422及第三固持件423之位置,從而調整固持槽425之大小及形狀使其與一待充電之電池之型號相對應。然後將電池容置於固持槽425中,並使電池上設有充電連接點之側面朝向固持槽425之缺口。調節電連接件424及與其相對之第二固持件422之位置,將電池之充電連接點與固定裝置40之電連接點4242相互接觸。這樣,充電電源即可通過適配器10向第二穩壓器312之輸入端312i輸入充電電壓,通過穩壓電路30之調整及電連接點4242之傳導,即可對電池進行充電。充電過程中,與該電池並聯之第一穩壓電阻R1及第二穩壓電阻R2可以使充電電壓保持穩定,而與電池串聯之保護電阻R3則可防止電池被直接接地而浪費電能。 In use, the positions of the second holding member 422 and the third holding member 423 are first adjusted to adjust the size and shape of the holding groove 425 to correspond to the type of the battery to be charged.

The position of the electrical connector 424 and the second holder 422 opposite thereto are adjusted to bring the charging connection point of the battery into contact with the electrical connection point 4242 of the fixture 40. In this way, the charging power source can input the charging voltage through the adapter 10 to the input terminal 312i of the second voltage regulator 312, and the battery can be charged by the adjustment of the voltage stabilizing circuit 30 and the conduction of the electrical connection point 4242. During the charging process, the first voltage stabilizing resistor R1 and the second voltage stabilizing resistor R2 connected in parallel with the battery can keep the charging voltage stable, and the protection resistor R3 connected in series with the battery can prevent the battery from being directly grounded and wasting power.
根據LM317晶片之性能可知,於一定範圍內,該第一穩壓器311之輸出端311o之輸出電壓Vo,亦即該電池之充電電壓僅與該第一穩壓電阻R1及該第二穩壓電阻R2之阻值有關,而與該第一穩壓器311之輸入端311i之輸入電 壓大小無關。其計算公式一般為Vo=1.25(1+R2/R1)。因此,通過調節可變之第二穩壓電阻R2之阻值,即可調節電池之充電電壓,並能將充電電壓穩定於所需之範圍內。另一方面,通過於連接第二穩壓器312之調節端312a與輸出端312o之切換開關32上選擇接通具有不同電阻之通路,則可以調節整個充電回路之電阻,進一步調節充電之電流。 According to the performance of the LM317 chip, the output voltage Vo of the output terminal 311o of the first voltage regulator 311, that is, the charging voltage of the battery is only related to the first voltage stabilizing resistor R1 and the second voltage regulator. The resistance of the resistor R2 is related to the input of the input terminal 311i of the first regulator 311. The size of the pressure is irrelevant. Its calculation formula is generally Vo=1.25 (1+R2/R1). Therefore, by adjusting the resistance of the variable second voltage stabilizing resistor R2, the charging voltage of the battery can be adjusted, and the charging voltage can be stabilized within a desired range. On the other hand, by selectively connecting the paths having the different resistances on the switch 32 connected to the regulating terminal 312a and the output terminal 312o of the second regulator 312, the resistance of the entire charging circuit can be adjusted to further adjust the charging current.
於充電過程中,監測電路30可以通過上述第一發光二極體22與第二發光二極體23分別發光來顯示電池之充電完成情況,以提醒使用者及時取出完成充電之電池。剛開始充電時電池之電壓極低,而第一穩壓電阻R1及第二穩壓電阻R2上之電壓較高(一般大於56mV)。此時電壓比較器21之第一同相輸入引腳213從穩壓電路30得到電壓輸入,而第一反相輸入引腳212則被通過保護電阻連接到接地點,其電壓低於第一同相輸入引腳213之電壓,使得第一輸出引腳211輸出高電平,反接至該第一輸出引腳211之第二發光二極體23處於截止狀態。另一方面,充電電源通過上述適配器10輸入該電壓比較器21之第二同相輸入引腳215及第二反相輸入引腳216之電壓相等,使第二輸出引腳217輸出低電平,進一步使得反接至第二輸出引腳217之第一發光二極體22被導通而發出紅光,表示電池處於充電過程中。 During the charging process, the monitoring circuit 30 can display the completion of charging of the battery by the first LED 2 and the second LED 23 respectively, to remind the user to take out the completed battery in time. The voltage of the battery is extremely low at the beginning of charging, and the voltage on the first voltage stabilizing resistor R1 and the second voltage stabilizing resistor R2 is relatively high (generally greater than 56 mV). At this time, the first non-inverting input pin 213 of the voltage comparator 21 obtains a voltage input from the voltage stabilizing circuit 30, and the first inverting input pin 212 is connected to the grounding point through a protective resistor, and the voltage thereof is lower than the first The voltage of the phase input pin 213 causes the first output pin 211 to output a high level, and the second light-emitting diode 23 connected to the first output pin 211 is in an off state. On the other hand, the charging power source inputs the voltages of the second non-inverting input pin 215 and the second inverting input pin 216 of the voltage comparator 21 through the adapter 10 to make the second output pin 217 output a low level, and further The first light-emitting diode 22 reversely connected to the second output pin 217 is turned on to emit red light, indicating that the battery is in the process of charging.
當電池充電完成後,電池具備了與穩壓器輸出相等之電壓,此時充電電流逐漸下降,第一同相輸入引腳213從穩壓電路30獲得之電壓逐漸下降,直至與第一反相輸入引腳212之電壓相等。此時第一輸出引腳211輸出低電平,使得反接至該第一輸出引腳211之第二發光二極體23導通發出綠光,表示電池充電完成;同時該低電平疊加到該第二反相輸入引腳216,導致第二同相輸入引腳215之電壓高於第二反相輸入引腳216之電壓,進而使第二輸出引腳217輸出高電平,導致反接之第一發光二極體22截止,用以表示電池正於充電之紅光熄滅。另外,反饋電阻R0可以於第一輸出引腳211與第一同相輸 入引腳213之間構成正反饋,防止於充電完成之臨界狀態出現兩個發光二極體同時導通而一起發光之現象。 When the battery is charged, the battery has a voltage equal to the output of the voltage regulator. At this time, the charging current gradually decreases, and the voltage obtained by the first non-inverting input pin 213 from the voltage stabilizing circuit 30 gradually decreases until it is inverted with the first phase. The voltage at input pin 212 is equal. At this time, the first output pin 211 outputs a low level, so that the second light-emitting diode 23 connected to the first output pin 211 is turned on to emit green light, indicating that the battery is charged; and the low level is superimposed on the The second inverting input pin 216 causes the voltage of the second non-inverting input pin 215 to be higher than the voltage of the second inverting input pin 216, thereby causing the second output pin 217 to output a high level, resulting in a reverse connection. A light-emitting diode 22 is turned off to indicate that the red light that the battery is charging is extinguished. In addition, the feedback resistor R0 can be in phase with the first output pin 211 A positive feedback is formed between the input pins 213 to prevent the two light-emitting diodes from being simultaneously turned on and emitting light together in a critical state of completion of charging.
