Description

消費性電子裝置、電池模組及消費性電子裝置的低溫啟動方法Consumer electronic devices, battery modules and low-temperature starting methods of consumer electronic devices

本發明係關於電子領域，尤其涉及一種消費性電子裝置、電池模組及消費性電子裝置的低溫啟動方法。The present invention relates to the field of electronics, and in particular, to a consumer electronic device, a battery module and a low-temperature starting method of the consumer electronic device.

目前消費性電子裝置通常使用鋰電池，其具有容量大、高密度、體積小的優點，而廣泛應用在手機、平板電腦、筆記型電腦等消費性電子裝置。然而，在低溫下，電池內部的電解液黏度，會隨著溫度降低而增加，鋰離子移動因而受阻，使得電池在低溫的放電效能變差。例如，以電容量4990mAh、放電截止電壓(Cut-off discharge voltage)3.0V為例，在攝氏23度時，電池蓄電量為100%。在攝氏-10度，僅剩下60%的電量。而以0.2C對電池抽載，在攝氏-21度僅剩下50%。以用0.5C對電池抽載，在攝氏25度時，電池約兩小時後電壓降到3V，但在攝氏-21度時，電池幾乎無法維持3.0V的電壓輸出。Currently, consumer electronic devices usually use lithium batteries, which have the advantages of large capacity, high density, and small size, and are widely used in consumer electronic devices such as mobile phones, tablet computers, and notebook computers. However, at low temperatures, the viscosity of the electrolyte inside the battery will increase as the temperature decreases, thereby hindering the movement of lithium ions, making the battery's discharge performance at low temperatures worse. For example, assuming a capacitance of 4990mAh and a cut-off discharge voltage of 3.0V, the battery storage capacity is 100% at 23 degrees Celsius. At -10 degrees Celsius, only 60% of the battery is left. When the battery is pumped at 0.2C, only 50% remains at -21 degrees Celsius. Using 0.5C to load the battery, at 25 degrees Celsius, the battery voltage dropped to 3V after about two hours. However, at -21 degrees Celsius, the battery could barely maintain a voltage output of 3.0V.

因此，這對於消費性電子裝置在低溫下的應用非常不利，待機、使用的時間大幅地縮短，在低的溫度下，電量消耗更劇，緊急狀況甚至無法開啟，而大幅地影響了消費性電子裝置的功能。Therefore, this is very unfavorable for the application of consumer electronic devices at low temperatures.

At low temperatures, power consumption is even greater, and even in emergency situations, consumer electronics cannot be turned on, which greatly affects consumer electronics. Functionality of the device.

雖然目前已有透過加熱器的方式來處理，來改善電解液的流動性，若是設置在消費性電子裝置內部設置加熱器，為了致動加熱器，在電路及傳輸規格需要大幅的變動，而若是透過外加式的加熱器，可能需要隨身攜帶加熱器及電源等，在攜帶上相對不便。Although heaters have been used to improve the fluidity of the electrolyte, if a heater is installed inside a consumer electronic device, in order to activate the heater, significant changes in circuit and transmission specifications are required, and if With an external heater, you may need to carry the heater and power supply with you, which is relatively inconvenient to carry.

如同前述的實施例可以理解的是，透過系統晶片及電池模組之間現有的資訊傳輸介面進行雙向傳輸，可以在符合原先設計的電池模組的輸出/輸入介面的規格下達到加熱器的啟動控制，而無須更動規格，或是利用外部加熱的方式對整個電池模組進行加熱來提升電池芯的溫度。As can be understood from the foregoing embodiments, through bidirectional transmission through the existing information transmission interface between the system chip and the battery module, the heater can be started in compliance with the specifications of the originally designed output/input interface of the battery module.

附圖中，為了清楚起見，放大了部分元件、區域等的寬度。在整個說明書中，相同的附圖標記表示相同的元件。In the drawings, the widths of some elements, regions, etc. are exaggerated for clarity. Throughout this specification, the same reference numbers refer to the same elements.

圖1為一實施例的消費性電子裝置的方塊示意圖。圖2為圖1中的電池模組一示範例的立體圖。圖3為一實施例的電池模組的電路圖。如圖1至圖3所示，消費性電子裝置1包含電池模組100及系統晶片200。電池模組100包含電池芯10、加熱器20、電池管理電路30及電連接器40。加熱器20位於電池芯10旁，並用以對電池芯10加溫。在此，圖2所顯示是將加熱器20包覆於電池芯10的外部，然而，這僅為示例，而非用以限制。舉例來說，因應實際需求，加熱器20亦可是直接貼附於電池芯10的上表面或下表面。FIG. 1 is a block diagram of a consumer electronic device according to an embodiment. FIG. 2 is a perspective view of an example of the battery module in FIG. 1 . FIG. 3 is a circuit diagram of a battery module according to an embodiment. As shown in FIGS. 1 to 3 , the consumer electronic device 1 includes a battery module 100 and a system chip 200 . The battery module 100 includes a battery cell 10, a heater 20, a battery management circuit 30 and an electrical connector 40. The heater 20 is located next to the battery core 10 and is used to heat the battery core 10 . Here, FIG. 2 shows that the heater 20 is wrapped around the outside of the battery cell 10. However, this is only an example and not a limitation. For example, depending on actual needs, the heater 20 can also be directly attached to the upper surface or lower surface of the battery cell 10 .

電池管理電路30耦接電池芯10及加熱器20。電連接器40包含資訊傳輸介面及電源傳輸介面。資訊傳輸介面包含存在接腳41，以及一個或多個資料接腳42(例如，系統時脈接腳421、系統資料接腳423等)。存在接腳41及資料接腳42耦接電池管理電路30。電源傳輸介面包含一對電源接腳43(例如，正電接腳及負電接腳)。在此，圖1中僅會出單一電源接腳43及單一資料接腳42以利於理解。電源接腳43耦接電池芯10。系統晶片200耦接存在接腳41及資料接腳42，經由資料接腳42接收來自電池管理電路30的電池資訊D。當於電池資訊D中的電池溫度低於第一閥值時，系統晶片200經由存在接腳41發出啟動信號A至電池管理電路30，以使電池管理電路30根據啟動信號A啟動加熱器20。The battery management circuit 30 is coupled to the battery cell 10 and the heater 20 . The electrical connector 40 includes an information transmission interface and a power transmission interface. The information transmission interface includes a presence pin 41 and one or more data pins 42 (eg, system clock pin 421, system data pin 423, etc.). There are pins 41 and data pins 42 coupled to the battery management circuit 30 . The power transmission interface includes a pair of power pins 43 (for example, a positive pin and a negative pin). Here, only a single power pin 43 and a single data pin 42 are shown in FIG. 1 to facilitate understanding. The power pin 43 is coupled to the battery cell 10 . The system chip 200 is coupled to the storage pin 41 and the data pin 42, and receives the battery information D from the battery management circuit 30 through the data pin 42. When the battery temperature in the battery information D is lower than the first threshold, the system chip 200 sends the activation signal A to the battery management circuit 30 via the presence pin 41 so that the battery management circuit 30 activates the heater 20 according to the activation signal A.

如此，透過系統晶片200及電池模組100之間現有的資訊傳輸介面進行雙向傳輸，可以在符合原先設計的電池模組100的輸出/輸入介面的規格下達到加熱器20的啟動控制，而無須更動規格，或是利用外部加熱的方式對整個電池模組100進行加熱來提升電池芯10的溫度。In this way, through bidirectional transmission through the existing information transmission interface between the system chip 200 and the battery module 100, the activation control of the heater 20 can be achieved under the specifications of the originally designed output/input interface of the battery module 100 without the need for Change the specifications, or use external heating to heat the entire battery module 100 to increase the temperature of the battery core 10 .

再次參閱圖1，消費性電子裝置1更包含供電電路300。供電電路300電性連接系統晶片200，並用以供電給系統晶片200。換言之，供電電路300可經由電源接腳43抽取電池芯10儲存的電源，並據以調整成系統晶片200所需位準的電源並供應給系統晶片200。Referring to FIG. 1 again, the consumer electronic device 1 further includes a power supply circuit 300 . The power supply circuit 300 is electrically connected to the system chip 200 and used to provide power to the system chip 200 . In other words, the power supply circuit 300 can extract the power stored in the battery cell 10 through the power pin 43 , and accordingly adjust the power to the level required by the system chip 200 and supply it to the system chip 200 .

在一些實施例中，電池模組100為一可拆式電池，即其為可拆式地組裝在消費性電子裝置1的主體上。於此，系統晶片200更經由存在接腳41確認電池模組100是否組裝在消費性電子裝置1的主體上，即判斷電源接腳43是否電性連接供電電路300。於電池模組100組裝在消費性電子裝置1的主體上時，存在接腳41會輸出電池存在信號P，因此，系統晶片200可經由偵測來自存在接腳41的電池存在信號P來判斷電源接腳43連接供電電路300。也就是說，當系統晶片200偵測到電池存在信號P時，系統晶片200即可據以判定電源接腳43與供電電路300已電性連接。In some embodiments, the battery module 100 is a detachable battery, that is, it is detachably assembled on the main body of the consumer electronic device 1 . Here, the system chip 200 further confirms whether the battery module 100 is assembled on the main body of the consumer electronic device 1 through the presence of the pin 41 , that is, it determines whether the power pin 43 is electrically connected to the power supply circuit 300 . When the battery module 100 is assembled on the main body of the consumer electronic device 1, the presence pin 41 will output the battery presence signal P. Therefore, the system chip 200 can determine the power source by detecting the battery presence signal P from the presence pin 41. Pin 43 is connected to the power supply circuit 300 . That is to say, when the system chip 200 detects the battery presence signal P, the system chip 200 can determine that the power pin 43 and the power supply circuit 300 are electrically connected.

在一些實施例中，電池管理電路30可更包含位準電路70。位準電路70用以將存在接腳41的位準拉至既定電位（即電池存在信號P）。在一些實施例中，位準電路70可包含耦接在存在接腳41與接地之間的阻抗元件。其中，此阻抗元件可為一電阻。更具體地，當偵測到來自存在接腳41的電池存在信號P，即，判斷電源接腳43電性連接供電電路300時，電池管理電路30透過位準電路70切換存在接腳41的電壓為低電壓位準，切換存在接腳41為輸出模式。In some embodiments, the battery management circuit 30 may further include a level circuit 70 . The level circuit 70 is used to pull the level of the presence pin 41 to a predetermined potential (ie, the battery presence signal P). In some embodiments, level circuit 70 may include an impedance element coupled between presence pin 41 and ground. Wherein, the impedance element can be a resistor. More specifically, when the battery presence signal P from the presence pin 41 is detected, that is, when it is determined that the power pin 43 is electrically connected to the power supply circuit 300 , the battery management circuit 30 switches the voltage of the presence pin 41 through the level circuit 70 is a low voltage level, switching pin 41 to output mode.

再次參閱圖1及圖2，電池管理電路30更可包含電池管理晶片50及電源開關60。電池管理晶片50耦接資料接腳42，並用以根據電池芯10的狀態生成電池資訊D。例如，電池管理晶片50透過控制電池芯10的充放電即偵測電池芯10的狀態來得到電池資訊D。例如，電池溫度、電量、使用時間等，並經由資料接腳42提供給系統晶片200進行判斷。電源開關60耦接存在接腳41，且耦接在電池芯10與加熱器20之間。於此，電源開關60會響應啟動信號A導通電池芯10與加熱器20，以啟動加熱器20。舉例來說，電源開關60常態為關閉(off)。電源開關60受控於啟動信號A，即於接收到啟動信號A時，電源開關60會從關閉切換為開啟(on)，而使得電池芯10經由電源開關60電性導通至加熱器20，即供電給加熱器20。Referring again to FIGS. 1 and 2 , the battery management circuit 30 may further include a battery management chip 50 and a power switch 60 . The battery management chip 50 is coupled to the data pin 42 and used to generate battery information D according to the status of the battery cell 10 . For example, the battery management chip 50 obtains the battery information D by controlling the charging and discharging of the battery cell 10 , that is, detecting the status of the battery cell 10 . For example, battery temperature, battery capacity, usage time, etc. are provided to the system chip 200 through the data pin 42 for judgment. The power switch 60 is coupled to the pin 41 and coupled between the battery cell 10 and the heater 20 . Here, the power switch 60 will respond to the activation signal A to connect the battery cell 10 and the heater 20 to activate the heater 20 . For example, the power switch 60 is normally off. The power switch 60 is controlled by the start signal A. That is, when receiving the start signal A, the power switch 60 will be switched from off to on, so that the battery cell 10 is electrically connected to the heater 20 through the power switch 60, that is, Power is supplied to heater 20.

如圖3所示，在一實施例中，電池管理晶片50可以利用gauge IC來實現，其透過熱敏電阻81來計算電池溫度。此外，電池芯10與電源接腳43之間，還可以設置有保護電路83，以避免突波或是過大的電壓造成電池芯10的損傷。As shown in FIG. 3 , in one embodiment, the battery management chip 50 can be implemented using a gauge IC, which calculates the battery temperature through the thermistor 81 . In addition, a protection circuit 83 may be provided between the battery cell 10 and the power pin 43 to prevent damage to the battery cell 10 caused by surges or excessive voltage.

在一些實施例中，電源開關60可以採用MOS或其他的電晶體開關，系統晶片200透過施加特定位準的電壓(即，啟動信號A)來開啟電源開關60。In some embodiments, the power switch 60 may be a MOS or other transistor switch, and the system chip 200 turns on the power switch 60 by applying a specific level of voltage (ie, activation signal A).

在一些實施例中，電連接器40、電源開關60、供電電路300更耦接到接地(ground)。In some embodiments, the electrical connector 40, the power switch 60, and the power supply circuit 300 are further coupled to ground.

再次參見圖1及圖3，雖然圖中未示出，本領域具有通常知識者可以理解的是，資料接腳42的數量可對應於系統規格。以系統晶片200與電池模組100的溝通介面為SM Bus時，資料接腳42可為一對，即系統時脈接腳421及系統資料接腳423。系統晶片200耦接電連接器40的系統時脈接腳421，並經由系統時脈接腳421與外部系統進行系統時脈信號（例如SM Bus clock）的傳送。另外，系統晶片200耦接電連接器40的系統資料接腳423，並且經由系統資料接腳423與外部系統進行系統資料信號（例如，SM Bus data）的傳送。換言之，電池管理晶片50更接收來自系統晶片200的系統時脈信號及系統資料信號，並據以將偵測到的電池模組100的狀態轉換為系統時脈信號及系統資料信號，再經由系統時脈接腳421及系統資料接腳423傳遞給系統晶片200。Referring again to FIGS. 1 and 3 , although not shown in the figures, those skilled in the art can understand that the number of data pins 42 may correspond to system specifications. When the communication interface between the system chip 200 and the battery module 100 is SM Bus, the data pins 42 may be a pair, namely a system clock pin 421 and a system data pin 423 . The system chip 200 is coupled to the system clock pin 421 of the electrical connector 40 and transmits a system clock signal (eg, SM Bus clock) with an external system through the system clock pin 421 . In addition, the system chip 200 is coupled to the system data pins 423 of the electrical connector 40 and transmits system data signals (eg, SM Bus data) with external systems via the system data pins 423 . In other words, the battery management chip 50 further receives the system clock signal and the system data signal from the system chip 200, and accordingly converts the detected status of the battery module 100 into the system clock signal and the system data signal, and then passes the system The clock pin 421 and the system data pin 423 are transmitted to the system chip 200 .

參見圖2，電池芯10、電連接器40、電池管理晶片50實際上是安裝於電路板35上，並封裝成一可拆式電池。供電電路300及系統晶片200則是形成在消費性電子裝置1主機板上並透過對應的電連接器40電性連接可拆式電池的電連接器40。Referring to Figure 2, the battery cell 10, the electrical connector 40, and the battery management chip 50 are actually installed on the circuit board 35 and packaged into a detachable battery. The power supply circuit 300 and the system chip 200 are formed on the motherboard of the consumer electronic device 1 and are electrically connected to the electrical connector 40 of the detachable battery through the corresponding electrical connector 40 .

在一些實施例中，系統晶片200更經由資料接腳42再次接收來自電池管理電路30的電池資訊D，當再次接收的電池資訊D中的電池溫度高於第二閥值時，系統晶片200經由存在接腳41傳送停止信號S(如，停止輸出啟動信號A)至電池管理電路30，以使電池管理電路30根據停止信號S停止加熱器20。舉例來說，當系統晶片200未輸出啟動信號A時，存在接腳41的位準因位準電路70而被下拉至第一電位。此時，電源開關60的控制端因耦接存在接腳41而為第一電位，以致於電源開關60的狀態因第一電位而為關閉。當系統晶片200輸出具有第二電位的啟動信號A時，存在接腳41的位準因啟動信號A而被上拉至第二電位。此時，電源開關60的控制端因耦接存在接腳41亦由第一電位上升為第二電位，以致於電源開關60的狀態由關閉切換為開啟。換句話說，啟動信號A與停止信號S可分別為第二電位與第一電位，且第二電位大於第一電位。In some embodiments, the system chip 200 further receives the battery information D from the battery management circuit 30 again via the data pin 42 . When the battery temperature in the battery information D received again is higher than the second threshold, the system chip 200 receives the battery information D via the data pin 42 . The presence pin 41 transmits the stop signal S (eg, stops outputting the start signal A) to the battery management circuit 30 so that the battery management circuit 30 stops the heater 20 according to the stop signal S. For example, when the system chip 200 does not output the enable signal A, the level of the presence pin 41 is pulled down to the first potential due to the level circuit 70 . At this time, the control end of the power switch 60 is at the first potential because it is coupled to the pin 41, so that the state of the power switch 60 is off due to the first potential. When the system chip 200 outputs the startup signal A with the second potential, the level of the presence pin 41 is pulled up to the second potential due to the startup signal A. At this time, the control end of the power switch 60 is coupled to the pin 41 and also rises from the first potential to the second potential, so that the state of the power switch 60 switches from off to on. In other words, the start signal A and the stop signal S may be the second potential and the first potential respectively, and the second potential is greater than the first potential.

在一些實施例中，第一閥值為攝氏-10至0度，較佳地為-5至0度；第二閥值是攝氏10至25度，較佳地為15至23度。但這僅為示例，而非用以限制，實際上可以考量消費性電子裝置1的種類、電池容量、使用環境來進行調整或設定。In some embodiments, the first threshold is -10 to 0 degrees Celsius, preferably -5 to 0 degrees Celsius; the second threshold is 10 to 25 degrees Celsius, preferably 15 to 23 degrees Celsius. However, this is only an example and not a limitation. In fact, adjustments or settings can be made taking into account the type, battery capacity, and usage environment of the consumer electronic device 1 .

圖4為一實施例的消費性電子裝置的低溫啟動方法的流程圖。如圖4所示，同時參考圖1，消費性電子裝置的低溫啟動方法S1包含：步驟S20，經由電池模組100的資料接腳42接收電池模組100的電池資訊D；步驟S30，比較電池資訊中電池溫度與第一閥值；當電池溫度低於第一閥值時，進入步驟S40，切換存在接腳41為輸出，經由資料存在接腳41發出啟動信號A給電池模組100，以啟動電池模組100內建的加熱器20；若是電池溫度高於第一閥值時、或是經由資料接腳42再次接收電池模組100的電池資訊D中的電池溫度高於第一閥值時，進入步驟S50，在電池模組100的供電下進行消費性電子裝置1的開機程序。FIG. 4 is a flow chart of a low-temperature starting method of a consumer electronic device according to an embodiment. As shown in FIG. 4 and referring to FIG. 1 , the low-temperature starting method S1 of the consumer electronic device includes: step S20, receiving the battery information D of the battery module 100 through the data pin 42 of the battery module 100; step S30, comparing the batteries. The battery temperature and the first threshold value in the information; when the battery temperature is lower than the first threshold value, step S40 is entered, the existence pin 41 is switched to the output, and the start signal A is sent to the battery module 100 through the data existence pin 41 to Start the built-in heater 20 of the battery module 100; if the battery temperature is higher than the first threshold, or the battery temperature in the battery information D of the battery module 100 is received again through the data pin 42 is higher than the first threshold. When , step S50 is entered, and the booting process of the consumer electronic device 1 is performed under the power supply of the battery module 100 .

更詳細地，在步驟S40中，啟動信號A可以為脈衝寬度調變信號(PWM)，在一些實施例中，還可以依據電池溫度調整脈衝調變信號(PWM)的輸出比。例如，脈衝調變信號的輸出比與電池攝氏溫度成正比，且輸出比為正值，在一些實施例中，輸出比alpha(α)為(電池攝氏溫度/-29)，且0＜α＜1。In more detail, in step S40, the start signal A may be a pulse width modulation signal (PWM). In some embodiments, the output ratio of the pulse width modulation signal (PWM) may also be adjusted according to the battery temperature. For example, the output ratio of the pulse modulation signal is proportional to the battery temperature in degrees Celsius, and the output ratio is a positive value. In some embodiments, the output ratio alpha (α) is (battery temperature in degrees Celsius/-29), and 0<α< 1.

在一些實施例中，消費性電子裝置的低溫啟動方法S1，在步驟S20之前更包含：步驟S10，系統晶片200偵測來自存在接腳41的電池存在信號P，確認電池模組100的電源接腳43是否電性連接供電電路300。系統晶片200若是持續未偵測電池存在信號P判斷電源接腳43未電性連接供電電路300時，則進入步驟S15，發出通知信息，例如，在顯示螢幕上呈現電池未電性連接的資訊。In some embodiments, the low-temperature startup method S1 of the consumer electronic device further includes before step S20: step S10, the system chip 200 detects the battery presence signal P from the presence pin 41, and confirms the power connection of the battery module 100. Whether pin 43 is electrically connected to the power supply circuit 300. If the system chip 200 continues to fail to detect the battery presence signal P and determines that the power pin 43 is not electrically connected to the power supply circuit 300 , it proceeds to step S15 and sends a notification message, for example, a message that the battery is not electrically connected is displayed on the display screen.

在一些實施例中，消費性電子裝置的低溫啟動方法，在步驟S40之後，更回到步驟S20，再次經由電池模組100的資料接腳42接收電池模組100的電池資訊D；步驟S60，比較電池資訊D中電池溫度與第二閥值；以及當再次接收的電池資訊D中的電池溫度高於第二閥值時，進入步驟S70，經由存在接腳41傳送停止信號S至電池管理電路30，以使電池管理電路30根據停止信號停止加熱器20。In some embodiments, the low-temperature starting method of the consumer electronic device returns to step S20 after step S40, and receives the battery information D of the battery module 100 again through the data pin 42 of the battery module 100; step S60, Compare the battery temperature in the battery information D with the second threshold; and when the battery temperature in the battery information D received again is higher than the second threshold, enter step S70 and send the stop signal S to the battery management circuit via the presence pin 41 30, so that the battery management circuit 30 stops the heater 20 according to the stop signal.

綜上所述，消費性電子裝置1透過系統晶片200及電池模組100之間現有的資訊傳輸介面進行雙向傳輸，可以在符合原先設計的電池模組100的輸出/輸入介面的規格下達到加熱器20的啟動控制，而無須更動規格，或是利用外部加熱的方式對整個電池模組100進行加熱來提升電池芯10的溫度。In summary, the consumer electronic device 1 performs bidirectional transmission through the existing information transmission interface between the system chip 200 and the battery module 100, and can achieve heating under the specifications of the originally designed output/input interface of the battery module 100. The start-up control of the inverter 20 does not need to change the specifications, or use external heating to heat the entire battery module 100 to increase the temperature of the battery core 10 .
