The electronic device can be a mobile phone or a PDA (personal Digital assistant, personal digital assistant, handheld game console, digital camera or handheld computer. In the preferred embodiment, the electronic device is a cell phone 1.
所述手機1在透過一個充電器(未示出)連接到一個電源3上以對電池28進行充電。所述硬體充電保護電路26用於在對電池28進行充電時進行一個硬體電路的保護，其包括過電壓/電池保護電路260及GPIO(general purpose input/output)斷路電路262。 The handset 1 is connected to a power source 3 via a charger (not shown) to charge the battery 28. The hardware charging protection circuit 26 is configured to protect a hardware circuit when charging the battery 28, and includes an over voltage/battery protection circuit 260 and a GPIO (general purpose input/output) circuit 262.
所述手機1還包括設置模組21、偵測模組22、執行模組24。 The mobile phone 1 further includes a setting module 21, a detecting module 22, and an executing module 24.
所述設置模組21用於設置掃描手機1的電池28在充電狀態下是否出現異常狀態的時間間隔。例如，可設置電池28進入充電狀態後每隔3秒鐘進行一次掃描。 The setting module 21 is configured to set a time interval for scanning whether the battery 28 of the mobile phone 1 has an abnormal state in a charging state. For example, the battery 28 can be set to scan every 3 seconds after entering the state of charge.
所述偵測模組22用於在電池28進入充電前掃描一次以偵測是否出現異常狀況。在充電前，所述偵測模組22進行掃描一次電池28以偵測該電池28的ID(identification)是否正確、電池溫度是否正常、正負極是否正確、電池電壓是否符合規範。 The detecting module 22 is configured to scan the battery 28 before charging to enter to detect whether an abnormal condition occurs. Before charging, the detecting module 22 scans the battery 28 to detect whether the ID of the battery 28 is correct, whether the battery temperature is normal, whether the positive and negative electrodes are correct, and whether the battery voltage meets the specifications.
所述執行模組24用於當偵測到電池28在充電前出現有異常狀況時，則進行相應的異常狀態排除並進行異常狀態的提醒。具體而言，當電壓過大或電流過大時，利用硬體充電保護電路26中的過電壓/電流保護電路260進行電壓或電流的保護，同時利用硬體充電保護電路26中的GPIO斷路電路262將充電器與手機1內部的通路進行斷路；當電池28的溫度過高或者電池正負極放反了，則所述執行模組24直接利用GPIO斷路電路262將充電器與手機1的內部通路進行斷路。同時，所述手機1的顯示螢幕上還將相應的異常狀態顯示出來，例如，在手機顯示螢幕顯示“溫度超高”、“電壓過 大”、“電流過大”、“無效電池”等提示用語。此外，還可透過聲音進行以上的提示。用戶亦可以根據以上提示來排除異常。 The execution module 24 is configured to perform a corresponding abnormal state exclusion and perform an abnormal state reminder when it is detected that the battery 28 has an abnormal condition before charging. Specifically, when the voltage is too large or the current is too large, the voltage or current is protected by the overvoltage/current protection circuit 260 in the hardware charging protection circuit 26 while using the GPIO breaking circuit 262 in the hardware charging protection circuit 26. The charger and the internal passage of the mobile phone 1 are disconnected; when the temperature of the battery 28 is too high or the positive and negative terminals of the battery are reversed, the execution module 24 directly disconnects the internal passage of the charger and the mobile phone 1 by using the GPIO breaking circuit 262. . At the same time, the corresponding abnormal state is displayed on the display screen of the mobile phone 1, for example, the display screen of the mobile phone displays "high temperature" and "voltage over". The prompts such as "large", "current is too large", "invalid battery", etc. In addition, the above prompts can also be made through the sound. The user can also exclude the abnormality according to the above tips.
所述執行模組24還用於在電池28充電前未出現任何異常狀況時，則讓電池28進入充電狀態。為了確保充電安全，在本較佳實施例中，可先採用小電流充電然後再利用大電流充電。例如，可在充電初期充入75mA的電流，而後充入750mA的電流。 The execution module 24 is also used to put the battery 28 into a charging state when no abnormal condition occurs before the battery 28 is charged. In order to ensure charging safety, in the preferred embodiment, charging with a small current and then charging with a large current may be employed. For example, a current of 75 mA can be charged at the initial stage of charging, and then a current of 750 mA is charged.
所述偵測模組22還用於在充電過程中每隔一設置的時間間隔進行一次掃描以偵測當前電壓、電流、電池溫度是否異常等。 The detecting module 22 is further configured to perform scanning every other set time interval during the charging process to detect whether the current voltage, current, battery temperature is abnormal, or the like.
在充電過程中，當所述偵測模組22偵測到異常狀況時，所述執行模組24則進行相應的異常狀態排除並進行異常狀態的提示。 During the charging process, when the detection module 22 detects an abnormal condition, the execution module 24 performs a corresponding abnormal state exclusion and prompts an abnormal state.
圖2是所述電子裝置進行安全充電的方法的工作流程圖。 2 is a flow chart showing the operation of the method for safe charging of the electronic device.
步驟S201，設置模組21設置掃描手機1的電池28在充電狀態下是否出現異常狀態的時間間隔。例如，可設置待電池28進入充電狀態後每隔3秒鐘進行一次掃描。 In step S201, the setting module 21 sets a time interval for scanning whether the battery 28 of the mobile phone 1 has an abnormal state in the charging state. For example, it is possible to set a scan every three seconds after the battery 28 enters the charging state.
步驟S202，手機1***充電器並連接上電源3以準備開始充電，所述偵測模組22在充電前進行一次掃描以偵測異常狀態。如偵測當前電池的溫度是否過高、充電電流及電壓是否過大、電池正負極是否裝反等。 In step S202, the mobile phone 1 is inserted into the charger and connected to the power source 3 to start charging. The detecting module 22 performs a scan before charging to detect an abnormal state. For example, if the current battery temperature is too high, the charging current and voltage are too large, and whether the battery is negative or not.
步驟S203，根據以上偵測結果判斷是否有異常狀況。如果出現異常狀況，則進入步驟S207；相反地，則進入步驟S204。 Step S203, determining whether there is an abnormal condition according to the above detection result. If an abnormal condition occurs, the process proceeds to step S207; conversely, the process proceeds to step S204.
步驟S204，當在充電前未偵測到異常狀況時，則對所述電池28進行充電並在設置的時間間隔內偵測各種狀態。 In step S204, when an abnormal condition is not detected before charging, the battery 28 is charged and various states are detected within the set time interval.
步驟S205，手機1判斷所述電池28在充電過程中是否出現異常狀況。如果出現異常狀況，則進入步驟S207，相反地，則進入步驟S206。 In step S205, the mobile phone 1 determines whether the battery 28 has an abnormal condition during charging. If an abnormal condition occurs, the process proceeds to step S207, and conversely, the process proceeds to step S206.
在步驟S206，判斷是否充電結束。如果充電結束，則流程結束；相反地，則返回步驟S204。 In step S206, it is determined whether or not charging is completed. If the charging is completed, the flow ends; otherwise, the process returns to step S204.
在步驟S207，當偵測到出現異常狀況，則進行相應的異常狀況排除、進行異常狀況提示，並結束充電。具體而言，當電壓過大或電流過大時，利用硬體充電保護電路26中的過電壓/電流保護電路260進行電壓或電流的保護，同時利用硬體充電保護電路26中的GPIO斷路電路262將充電器與手機1內部的通路進行斷路；當電池28的溫度過高或者電池正負極放反了，則所述執行模組24直接利用GPIO斷路電路262將充電器與手機1的內部通路進行斷路。同時，所述手機1的顯示螢幕上還將顯示相應的異常狀態，例如，在手機顯示螢幕顯示“溫度超高”、“電壓過大”、“電流過大”、“無效電池”等提示用語。此外，還可透過聲音進行以上的提示。用戶亦可以根據以上提示來排除異常。 In step S207, when an abnormal condition is detected, the corresponding abnormal condition is excluded, the abnormal condition is prompted, and the charging is ended. Specifically, when the voltage is too large or the current is too large, the voltage or current is protected by the overvoltage/current protection circuit 260 in the hardware charging protection circuit 26 while using the GPIO breaking circuit 262 in the hardware charging protection circuit 26. The charger and the internal passage of the mobile phone 1 are disconnected; when the temperature of the battery 28 is too high or the positive and negative terminals of the battery are reversed, the execution module 24 directly disconnects the internal passage of the charger and the mobile phone 1 by using the GPIO breaking circuit 262. . At the same time, the corresponding abnormal state is also displayed on the display screen of the mobile phone 1, for example, on the mobile phone display screen, the prompt words such as “high temperature”, “excessive voltage”, “current too large”, “invalid battery” are displayed. In addition, the above tips can be made through the sound. Users can also follow the above tips to exclude exceptions.
