[0051] At least some of the operations of FIG. 3 may be omitted. The order of the operations of FIG. 3 may be changed. Operations other than those of FIG. 3 may be performed before, during, or after the operations of FIG. 3.
[0052] Referring to FIG. 3, the charging and overcharge prevention modes of the battery (220) can be described.
[0053] Referring to FIG. 3, in operation 301, according to one embodiment, the electronic device (101) may receive power (e.g., input power) provided from the power provider (200). The power provider (200) may provide power (e.g., input power) to the electronic device (101). The electronic device (101) may receive power (e.g., input power) from the power provider (200).
[0054] In operation 303, according to one embodiment, the electronic device (101) may charge the battery (220) based on power (e.g., input power) provided from the power provider (200). For example, the electronic device (101) may convert power (e.g., input power) provided from the power provider (200) through the charger (210) and output the converted power (e.g., output power). The electronic device (101) may charge the battery (220) based on the output power output from the charger (210).
[0055] In operation 305, according to one embodiment, the electronic device (101) may compare the charge amount of the battery (220) with a threshold value. For example, the electronic device (101) may check the charge amount of the battery (220). The charge amount of the battery (220) may be the amount charged of the battery (220) or the remaining amount of the battery (220). The charge amount of the battery (220) may also be the ratio of the current charge amount to the maximum charge amount of the battery (220). In other words, the charge amount may be a concept including a charge rate. The threshold value may be a value set for protecting the battery (220). For example, if the threshold value is 85%, the electronic device (101) may determine whether the charge amount (e.g., charge rate) of the battery (220) exceeds 85%. For example, if the threshold value is 4,250 mAh, the electronic device (101) can determine whether the charge amount of the battery (220) exceeds 4,250 mAh.
[0056] In operation 307, according to one embodiment, the electronic device (101) may determine an overcharge prevention mode based on whether the charge amount of the battery (220) exceeds a threshold value. The electronic device (101) may enter an overcharge prevention mode based on whether the charge amount of the battery (220) exceeds the threshold value. The overcharge prevention mode may include a mode for performing an operation to prevent overcharging of the battery (220). According to one embodiment, the electronic device (101) may perform an overcharge prevention mode corresponding to a user setting. For example, the electronic device (101) may perform a first overcharge prevention mode corresponding to the first user setting based on a first user setting, and may perform a second overcharge prevention mode corresponding to the second user setting based on a second user setting, and there is no limitation on the types and numbers of user settings and overcharge prevention modes. For example, the electronic device (101) may, based on a first user setting to which the first overcharge prevention mode is applied, determine the first overcharge prevention mode while the charge amount of the battery (220) exceeds a threshold value, and perform an operation corresponding to the first overcharge prevention mode. For example, the electronic device (101) may, based on a second user setting to which the second overcharge prevention mode is applied, determine the second overcharge prevention mode while the charge amount of the battery (220) exceeds a threshold value, and perform an operation corresponding to the second overcharge prevention mode. For example, in the second overcharge prevention mode, the first output power from the charger (210) to the load (230) may be cut off, and the second output power may be provided from the battery (220) to the load (230). For example, the electronic device (101) may continue to charge the battery (220) based on the output power of the charger (210) without applying the overcharge protection mode while the charge amount of the battery (220) exceeds the threshold value and is below the maximum charge amount, based on a third user setting where the overcharge protection mode is not applied.
[0057] An embodiment of the overcharge protection mode will be described with reference to FIG. 4.
[0058] FIG. 4 is a flowchart of a method of operating an electronic device according to one embodiment. FIG. 5 is a diagram illustrating the operation of an electronic device according to one embodiment.
[0059] At least some of the operations of FIG. 4 may be omitted. The order of the operations of FIG. 4 may be changed. Operations other than those of FIG. 4 may be performed before, during, or after the operations of FIG. 4.
[0060] Referring to FIG. 4, the input power limit value and overcharge prevention mode of the charger (210) can be described. The input power limit value of the charger (210) may be a set value for limiting the input power provided from the power provider (200) and input to the charger (210) to a certain range. For example, the input power limit value of the charger (210) may be a value for limiting the value of the input current input to the charger (210) to below the limit value. For example, when the limit value is set to 5.5 A, the input current input to the charger (210) may be limited to 5.5 A or below. The input power limit value of the charger (210) may include a first limit value and a second limit value. For example, the first limit value may be a software limit value (e.g., S / W ACLimit) related to the rated capacity of the power provider (200). For example, the first limit value may be a software limit value (e.g., S / W ACLimit) that limits the input current of the power provider (200) set by negotiation of power requirements (e.g., PD negotiation (power delivery negotiation)) according to the rated capacity of the power provider (200) (e.g., travel adapter). For example, the second limit value may be a hardware limit value (e.g., H / W ACLimit) related to the resistance value of a resistor electrically connected to the charger (210). For example, the second limit value may be a hardware limit value (e.g., H / W ACLimit) that limits the input current of the charger (210) by changing the resistance value of the resistor electrically connected to the charger (210). The input power of the charger (210) may be limited based on a smaller value of the first limit value and the second limit value. Before and after applying the overcharge prevention mode, the limit values of the input power of the charger (210) may be set differently.
[0061] Referring to FIG. 4, in operation 401, according to one embodiment, the electronic device (101) may set a first value as a first limit value of the input power of the charger (210) based on communication with the power provider (200). The first limit value may be related to a rated capacity of the power provider (200). For example, the electronic device (101) may communicate with the power provider (200). For example, the electronic device (101) may communicate with the power provider (200) through a power delivery integrated circuit (PD IC) (e.g., the PD IC (910) of FIG. 9). The electronic device (101) may negotiate with the power provider (200) for input power based on the communication with the power provider (200). The electronic device (101) can confirm the rated capacity of the power provider (200) based on communication with the power provider (200). The electronic device (101) can confirm a first value (e.g., a value corresponding to the rated capacity of the power provider (200)) of a first limit value related to the rated capacity of the power provider (200) based on negotiation (e.g., a limit value related to the rated capacity of the power provider (200). The electronic device (101) can set the first value as the first limit value. For example, the electronic device (101) can provide a control signal to the charger (210) that causes the first value to be set as the first limit value. The charger (210) can set the first value as the first limit value based on the control signal.
[0062] In operation 403, according to one embodiment, the electronic device (101) may set a second value greater than a first value (e.g., a value set as the first limit value in operation 401) as the second limit value of the input power of the charger (210). According to one embodiment, operation 403 may be performed when the charge amount of the battery (220) is below a threshold value. The second limit value may be related to a resistance value of a resistor electrically connected to the charger (210). The operation of setting the second value greater than the first value (e.g., a value set as the first limit value in operation 401) as the second limit value of the input power of the charger (210) may be a default operation. For example, the electronic device (101) may maintain the second limit value of the input power of the charger (210) at the second value greater than the first value (e.g., a value set as the first limit value in operation 401) while the charge amount of the battery (220) is below the threshold value. Based on the second limit value, the resistance value of the resistor electrically connected to the charger (210) can be determined. The second limit value can be set according to the resistance value of the resistor electrically connected to the charger (210). For example, the electronic device (101) can set a second value greater than the first value set as the first limit value in operation 401 as the second limit value of the input power of the charger (210) while the overcharge prevention mode is not confirmed (e.g., while the charge amount of the battery (220) is below the threshold value). For example, the electronic device (101) can include a resistor circuit (250). The resistor circuit (250) can include a first resistor (251) and a first switch (252) configured to electrically connect the first resistor (251) to the charger (210). The electronic device (101) can determine whether to turn on or off the first switch (252), which is configured to electrically connect the first resistor (251) to the charger (210), based on the second limit value. The electronic device (101) can control whether to turn on or off the first switch (252) based on the second limit value.The electronic device (101) can control the on or off of the first switch (252) to check the second limit value and set the second limit value. Based on the on or off of the first switch (252), the resistance value of the resistor electrically connected to the charger (210) (e.g., the resistance value of the circuit including 251, 253, and / or 254 of FIG. 2) can be set.
[0063] In one embodiment, the input power of the charger (210) may be limited based on the smaller of the first limit value and the second limit value.
[0064] In operation 405, according to one embodiment, the electronic device (101) may output a first output power (e.g., power output from the charger (210)) (e.g., charger output power) through the charger (210) based on an input power limited by a first limit value (e.g., a first value set as the first limit value in operation 401) that is less than a second limit value (e.g., a second value set as the second limit value in operation 403). According to one embodiment, operation 405 may be performed when the charge amount of the battery (220) is less than a threshold value. For example, the electronic device (101) may charge the battery (220) based on the first output power output through the charger (210). For example, the electronic device (101) may perform an operation of the load (230) based on the first output power output through the charger (210). For example, the electronic device (101) can perform the operation of the load (230) while charging the battery (220) based on the first output power output through the charger (210).
[0065] In operation 407, according to one embodiment, the electronic device (101) may compare the charge level of the battery (220) with a threshold value. Operation 407 may be understood similarly to the description of operation 305 of FIG. 3.
[0066] In operation 409, according to one embodiment, the electronic device (101) may determine an overcharge prevention mode based on whether the charge amount of the battery (220) exceeds a threshold value. The electronic device (101) may enter the overcharge prevention mode based on whether the charge amount of the battery (220) exceeds the threshold value. Operation 409 may be understood similarly to the description of operation 307 of FIG. 3 . For example, the electronic device (101) may determine a first user setting. The electronic device (101) may determine the first overcharge prevention mode and perform an operation corresponding to the first overcharge prevention mode while the charge amount of the battery (220) exceeds the threshold value based on the first user setting to which the first overcharge prevention mode is applied. The operation corresponding to the first overcharge prevention mode may include operations 411, 413, and 415.
[0067] In operation 411, according to one embodiment, the electronic device (101) may set a third value smaller than a first value (e.g., a value set as a first limit value in operation 401) as a second limit value of the input power of the charger (210). For example, the electronic device (101) may set a third value smaller than a first value (e.g., a value set as a first limit value in operation 401) as a second limit value of the input power of the charger (210) based on confirmation of an overcharge prevention mode (e.g., a first overcharge prevention mode in operation 409). For example, the electronic device (101) may set a third value smaller than a first value (e.g., a value set as a first limit value in operation 401) as a second limit value of the input power of the charger (210) based on the charge amount of the battery (220) exceeding a threshold value. For example, the electronic device (101) may control the first switch (252) to turn on so as to set the third value as the second limit value based on confirmation of the overcharge prevention mode (e.g., based on the charge amount of the battery (220) exceeding the threshold value). For example, in operation 403, the electronic device (101) may control the first switch (252) to turn off so as to set the second value as the second limit value based on the charge amount of the battery (220) being below the threshold value. However, those skilled in the art will understand that the on or off of the first switch (252) may be changed depending on the connection relationship of the resistors and the design of the circuit.
[0068] In one embodiment, the input power of the charger (210) may be limited based on the smaller of the first limit value and the second limit value.
[0069] In operation 413, according to one embodiment, the electronic device (101) may output a first output power (e.g., power output from the charger (210)) through the charger (210) based on an input power limited by a second limit value (e.g., a third value set as the second limit value in operation 411) that is less than a first limit value (e.g., a first value set as the first limit value in operation 401). For example, the electronic device (101) may perform an operation of the load (230) based on the first output power output through the charger (210).
[0070] In operation 415, according to one embodiment, the electronic device (101) may provide a second output power (e.g., power output from the battery (220)) (e.g., battery output power) from the battery (220) to the load (230) while providing a first output power (e.g., power output from the charger (210) in operation 413) to the load (230) based on a second limit value (e.g., a third value set as the second limit value in operation 411). Accordingly, as shown in FIG. 5, while input power is provided from the power provider (200), the first output power (e.g., power output from the charger (210)) and the second output power (e.g., power output from the battery (220)) may be provided to the load (230). For example, the electronic device (101) can control the second switch (260) (e.g., a switch configured to electrically connect the charger (210) and the load (230)) and the third switch (270) (e.g., a switch configured to electrically connect the battery (220) and the load (230)) to be turned on to provide the first output power (e.g., power output from the charger (210)) and the second output power (e.g., power output from the battery (220)) to the load (230) while the overcharge prevention mode is maintained (e.g., while the charge amount of the battery (220) exceeds a threshold value). The electronic device (101) can perform the operation of the load (230) based on the first output power (e.g., power output from the charger (210)) and the second output power (e.g., power output from the battery (220)). For example, by providing power required for high-performance operation of a load (230) of an electronic device (101) to the load (230) as a first output power (e.g., power output from a charger (210)) and a second output power (e.g., power output from a battery (220)), the possibility of shutdown of the battery (220) can be reduced or prevented.For example, by dividing the power consumption of the load (230) into the first output power of the charger (210) and the second output power of the battery (220), the possibility of shutdown of the battery (220) can be reduced, while discharging the battery (220) so as to lower the charge amount of the battery (220) to a target remaining amount (e.g., a threshold value).
[0071] According to one embodiment, the electronic device (101) may check the charge amount of the battery (220) and perform operation 407 while providing the first output power (e.g., power output from the charger (210)) and the second output power (e.g., power output from the battery (220)) to the load (230) in operations 413 and 415. Thereafter, the electronic device (101) may perform operations 403 and 405, or operations 409, 411, 413, and 415. For example, the electronic device (101) may set a second value (e.g., a value set as the second limit value in operation 403) greater than a first value (e.g., a value set as the first limit value in operation 401) based on the charge amount of the battery (220) being less than a threshold value. For example, the electronic device (101) may control the first switch (252) to be turned off to set the second value as the second limit value based on the charge amount of the battery (220) being less than the threshold value. The electronic device (101) may output the first output power through the charger (210) based on the input power limited by the first limit value (e.g., the first value set as the first limit value in operation 401) that is less than the second limit value (e.g., the second value set as the second limit value in operation 403) and may refrain from providing the second output power from the battery (220) to the load (230).
[0072] FIG. 6 is a diagram illustrating user settings of an electronic device according to one embodiment.
[0073] Referring to FIG. 6, the user settings of operation 307 of FIG. 3 and operation 409 of FIG. 4 can be described.
[0074] Referring to FIG. 6, according to one embodiment, the electronic device (101) may display a screen for selecting application of an overcharge prevention mode on the display (160). The display (160) may be a display included in the display module (160) of FIG. 1. As shown in FIG. 6, based on a user setting that selects “battery protection” (e.g., a user setting that applies an overcharge prevention mode), while the charge amount of the battery (220) exceeds a threshold value, the overcharge prevention mode (e.g., an overcharge prevention mode corresponding to the user setting) may be checked, and an operation corresponding to the checked overcharge prevention mode may be performed. Based on a user setting that does not select “battery protection” (e.g., a user setting that does not apply an overcharge prevention mode), while the charge amount of the battery (220) exceeds the threshold value and is below the maximum charge amount, the battery (220) may be continuously charged based on the output power of the charger (210).
[0075] FIG. 7 is a drawing illustrating a screen display of an electronic device according to one embodiment.
[0076] According to one embodiment, while the operation of FIG. 4 is performed, the electronic device (101) may display the screen of FIG. 7. The electronic device (101) may control the display (160) to display a screen including an object (720) indicating the charge level of the battery (220). The electronic device (101) may control the display (160) to display a screen including an object (710) indicating that input power provided from the power provider (200) is being received. The object (710) indicating that input power provided from the power provider (200) is being received may be implemented in a design in which the battery (220) is charged, but there is no limitation thereto.
[0077] According to one embodiment, the electronic device (101) may control the display (160) to display a screen including an object (710) indicating that input power provided from the power provider (200) is being received while limiting the input power based on a first limit value (e.g., a value set as the first limit value in operation 401). For example, in operation 405, while the battery (220) is being charged, the electronic device (101) may control the display (160) to display a screen including an object (710) indicating that input power provided from the power provider (200) is being received.
[0078] According to one embodiment, the electronic device (101) may control the display (160) to display a screen including an object (710) indicating that input power provided from the power provider (200) is being received while limiting the input power based on the second limit value (e.g., the third value set as the second limit value in operation 411). For example, in operations 413 and 415, while the operation of the load (230) is performed based on the first output power (e.g., power output from the charger (210)) and the second output power (e.g., power output from the battery (220)), the electronic device (101) may control the display (160) to display a screen including an object (710) indicating that input power provided from the power provider (200) is being received.
[0079] FIG. 8 is a graph illustrating the operation of an electronic device according to one embodiment.
[0080] In Fig. 8, VBUS may be an adapter voltage provided from a power provider (200). IBUS may be an adapter current provided from a power provider (200). IBAT may be a battery current. PHOT may be a signal indicating an abnormal situation, including a case where the temperature of at least one component of the electronic device (101) exceeds a reference value. For example, PHOT may be maintained at high in a normal situation and maintained at low in an abnormal situation.
[0081] Referring to FIG. 8, it can be confirmed that while the operation of FIG. 4 is performed, the adapter current (VBUS) and the adapter current (IBUS) are supplied appropriately, the battery current (IBAT) is supplied appropriately, and the PHOT is maintained at high (e.g., normal situation). For example, in FIG. 4, while the operation of the load (230) is performed based on the first output power (e.g., power output from the charger (210)) and the second output power (e.g., power output from the battery (220)), as shown in FIG. 8, the system of the electronic device (101) is maintained in a normal state, so that the possibility of the battery (220) being shut down due to the high-performance operation required by the load (230) can be reduced or prevented. For example, by dividing the power consumption of the load (230) into the first output power of the charger (210) and the second output power of the battery (220), the possibility of shutdown of the battery (220) can be reduced, while discharging the battery (220) so as to lower the charge amount of the battery (220) to a target remaining amount (e.g., a threshold value).
[0082] FIG. 9 is a block diagram of an electronic device according to one embodiment.
[0083] Referring to FIG. 9, according to one embodiment, the electronic device (101) may include a PD IC (910). According to one embodiment, the resistance circuit (250) of FIG. 2 may not be included. According to one embodiment, the operation of the PD IC (910) described below may be performed without performing the operation through the resistance circuit (250) of FIG. 2. According to one embodiment, both the operation through the resistance circuit (250) of FIG. 2 and the operation of the PD IC (910) described below may be performed.
[0084] According to one embodiment, the electronic device (101) may communicate with the power provider (200) through a power delivery integrated circuit (PD IC) (e.g., the PD IC (910) of FIG. 9). The electronic device (101) may negotiate with the power provider (200) regarding input power based on the communication with the power provider (200). The electronic device (101) may confirm the rated capacity of the power provider (200) based on the communication with the power provider (200). Based on the negotiation, the electronic device (101) may confirm a first value (e.g., a value corresponding to the rated capacity of the power provider (200) of a first limit value related to the rated capacity of the power provider (200) (e.g., a limit value related to the rated capacity of the power provider (200). The electronic device (101) may set the first value as the first limit value. For example, the electronic device (101) may provide a control signal to the charger (210) that causes the first value to be set to a first limit value. The charger (210) may set the first value to the first limit value based on the control signal. Thereafter, the electronic device (101) may perform operation 407 of FIG. 4 and determine an overcharge protection mode based on the charge amount of the battery (220) exceeding a threshold value. The electronic device (101) may perform a reset (e.g., a power delivery (PD) hardrest) operation based on determining the overcharge protection mode (e.g., based on the charge amount of the battery (220) exceeding a threshold value). The reset operation may include an operation of re-negotiating with the power provider (200) as if the power provider (200) (e.g., an adapter) were re-plugged in. For example, the electronic device (101) may request a lower capacity than the rated capacity of the existing power provider (200) (e.g., the rated capacity confirmed in operation 401).The electronic device (101) can provide first output power (e.g., power output from the charger (210)) and second output power (e.g., power output from the battery (220)) to the load (230) while input power of a capacity lower than the rated capacity (e.g., rated capacity confirmed in operation 401) is input to the charger (210) based on negotiation with the power provider (200).
[0085] Those skilled in the art will appreciate that the embodiments described herein may be applied interchangeably, within the scope of their applicability. For example, those skilled in the art will appreciate that at least some operations of one embodiment described herein may be omitted and applied, or at least some operations of one embodiment may be applied in conjunction.
[0086] The present disclosure is not limited to the foregoing, and other variations not mentioned will be apparent to those skilled in the art from the present disclosure.
[0087] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.
[0088] According to one embodiment, the electronic device (101) may include a charger (210) configured to convert input power provided from a power provider (200), a battery (220), a load (230), at least one processor (120, 240) including a processing circuit, and a memory (130) including instructions. The instructions, when individually or collectively executed by the at least one processor (120, 240), may cause the electronic device (101) to set a first value as a first limit value of the input power of the charger (210) based on communication with the power provider (200). The first limit value may be related to a rated capacity of the power provider (200). The instructions, when individually or collectively executed by the at least one processor (120, 240), may cause the electronic device (101) to set a second value greater than the first value as a second limit value of the input power of the charger (210). The second limit value may be related to a resistance value of a resistor electrically connected to the charger (210). The instructions, when individually or collectively executed by the at least one processor (120, 240), may cause the electronic device (101) to output a first output power through the charger (210) based on the input power limited by the first limit value less than the second limit value. The above instructions, when executed individually or collectively by the at least one processor (120, 240), may cause the electronic device (101) to check for an overcharge prevention mode of the battery (220) based on a charge amount of the battery (220) exceeding a threshold value.The instructions, when individually or collectively executed by the at least one processor (120, 240), may cause the electronic device (101) to set the second limit value of the input power of the charger (210) to a third value less than the first value based on the identification of the overcharge protection mode. The instructions, when individually or collectively executed by the at least one processor (120, 240), may cause the electronic device (101) to output the first output power through the charger (210) based on the input power limited by the second limit value less than the first limit value. The above instructions, when executed individually or collectively by the at least one processor (120, 240), may cause the electronic device (101) to provide a second output power from the battery (220) to the load (230) while providing the first output power to the load (230) based on the second limit value.
