Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the current game notebook computer design, in order to achieve both performance and portability, a special 300W adapter and a universal standard PD adapter are generally adopted, the output voltages of the special 300W adapter and the universal standard PD adapter are both 20V, the battery voltage can reach 17.2V at the highest, the threshold voltage of the adapter is 18V, wherein the special 300W adapter supports the maximum performance of the notebook computer, the universal standard PD adapter is portable and universal, the energy supply power range of the universal standard PD adapter is 45-135W, the charging and basic function requirements of the notebook computer are supported, the applicant finds that, because the total power of the notebook computer system is 300W, more capacitance is required, when the universal standard PD adapter is connected to the notebook computer, according to the law of charge conservation q=c, Δv= Δi t (wherein Q is the charge quantity, C is the capacitance, delta V is voltage variation, delta I current variation, t is time, C and delta V, t are based on a 300W system design), system capacitance is required to be charged from battery voltage to 20V, the lower the battery voltage is, the larger the delta V is, the larger the delta I is, the voltage of a PD adapter is easy to be instantaneously reduced below a set energy supply threshold voltage, and a notebook system cannot be supplied with energy (such as charging), particularly as shown in figure 1, so that the problem that energy cannot be supplied when the electronic equipment is overloaded due to the fact that a low-power PD adapter (such as a 45-135W universal standard PD adapter) is inserted under the condition of battery no-charge (dead battery) or low-charge of the electronic equipment is solved.
Based on the above, the present application provides a control method and an electronic device, which are used for solving the above problem, and the disclosed control method can be applied to electronic devices such as a notebook. Referring to the control method flowchart shown in fig. 2, the control method disclosed in the present application at least includes:
step 201, in response to detecting that the power adapter is connected to the electronic device with the first total power, determining the type of the connected power adapter.
Taking a game notebook computer as an example, the first total power of the electronic device may be 300W.
Wherein, in response to detecting that the power adapter is connected to the electronic device with the first total power, the electronic device may communicate with the connected power adapter through, but not limited to, a power manager of the electronic device, and/or a related controller such as a system controller EC, and the type of the connected power adapter is determined according to the communication information.
When the power adapter is connected to the electronic device, the electronic device can communicate with the power adapter through the power manager or the system controller, acquire the information of the charging power, the voltage and other energy supply capacity parameters of the power adapter through the communication process, and identify the type of the connected power adapter according to the acquired information of the energy supply capacity parameters.
In this embodiment of the present application, the types of the power adapters that are connected are two types based on the first total power division: one is a low power PD adapter of a first type representing a power supply adapter having a power supply lower than a first total power of the electronic device, such as the universal standard PD adapter having a power supply power in the range of 45-135W above; another is a second type representing a power supply adapter having an energizing power greater than or equal to the first total power of the electronic device, such as the special 300W adapter above.
The prior art controls the power supply of the power adapter to the electronic device by taking the default power supply threshold voltage as a reference, and once the voltage of the power adapter is lower than the default power supply threshold voltage, the power supply switch between the power adapter and the electronic device is turned off, which also causes that the power supply of the first type power adapter (such as a low-power PD adapter such as a 45-135W universal standard PD adapter) is inserted into the device under the conditions of no electric quantity, low electric quantity or heavy load of the battery, and the like, so that the power supply of the device system cannot be supplied due to the fact that the voltage of the power adapter is instantaneously reduced below the default power supply threshold voltage.
In view of this problem, in the present application, if the type of the power adapter is identified as the first type, the power supply threshold voltage of the power adapter is adjusted to be the first threshold voltage, for example, when the power supply threshold voltage of the power adapter is reduced from the original default power supply threshold voltage to the first threshold voltage, the power adapter supplies power to the electronic device by using the first threshold voltage as the power supply threshold voltage, so, even if the voltage of the power adapter is instantaneously reduced below the default power supply threshold voltage, as long as the voltage is not lower than the first threshold voltage, the power supply switch can still be ensured to be turned on, and then the normal power supply of the power adapter to the device system is ensured, so that the problem that the power supply cannot be supplied to the device system due to the instantaneous reduction of the voltage of the power adapter when the first type power adapter (such as the 45-135W universal standard PD adapter) is inserted into the device under the conditions of no battery, low battery or heavy load and the like is avoided.
In summary, in the control method of the embodiment of the present application, in response to detecting that the power adapter is connected to the electronic device having the first total power, the type of the connected power adapter is determined, and in the case that the type of the power adapter is the first type, the energy supply threshold voltage of the power adapter is reduced to the first threshold voltage, so that the power adapter supplies energy to the electronic device with the first threshold voltage as the energy supply threshold voltage, and due to the reduction of the functional threshold voltage of the electronic device, the problem that the energy cannot be supplied to the device system due to the instantaneous reduction of the voltage of the power adapter when the first type of the power adapter is inserted into the device under the conditions of no battery, low battery or heavy load or the like can be avoided at least to a certain extent.
In an alternative embodiment, referring to fig. 3, the step 202 may be further implemented as:
In this embodiment, when the type of the power adapter is identified as the first type, it is further determined whether the electronic device meets a preset condition, and the adjustment is performed only when the preset condition is met, that is, the energy supply threshold voltage of the power adapter is adjusted to be the first threshold voltage.
Alternatively, the preset condition may be set as: the electric quantity of the battery module in the electronic equipment is lower than a preset electric quantity threshold value.
For this condition, the electric quantity of the battery module in the electronic device can be obtained, and the electric quantity of the battery module is determined based on the preset electric quantity threshold, wherein when the electric quantity of the battery module is lower than the preset electric quantity threshold, for example, when the electric quantity of the battery module is 0 or a value between 0 and the preset electric quantity threshold, the energy supply threshold voltage of the power adapter is adjusted, and the current threshold voltage value (for example, the default energy supply threshold voltage) is reduced to the first threshold voltage, so that the problem that the power supply cannot be supplied to the device system due to the instantaneous reduction of the voltage of the power adapter is solved when the first type power adapter (for example, the 45-135W universal standard PD adapter) is inserted into the device under the conditions of no electric quantity and low electric quantity of the battery.
Alternatively, the system controller may directly obtain parameters related to the battery module, such as voltage and electric quantity, from a register (battery data) of the battery module, or may obtain the parameters by the power manager and transmit the parameters to the system controller. And then the energy supply threshold voltage adjustment processing based on the electric quantity judgment is executed in the system controller.
The first threshold voltage may be preset, specifically, a value smaller than a default power supply threshold voltage of the power adapter may be set as the first threshold voltage, or the value of the first threshold voltage may be dynamically determined according to a real-time voltage of the battery module in the electronic device, which is not limited.
In practical applications, the mode of dynamically determining the first threshold voltage according to the real-time voltage of the battery module may be preferable. In this implementation manner, the current voltage of the battery module may be obtained by, but not limited to, the system controller, the first threshold voltage is determined according to the current voltage of the battery module, and the energy supply threshold voltage of the power adapter is adjusted to the first threshold voltage by the threshold voltage adjusting module. Wherein, a voltage increment can be preset, and the sum of the voltage of the battery module and the increment is taken as a first threshold voltage. By setting the increment, the first threshold voltage is a value between the voltage of the battery module and the default energy supply threshold voltage, so that the battery module can be effectively supplied with energy, and the energy supply voltage of the first type power adapter is allowed to have larger instantaneous drop compared with the default energy supply threshold voltage, for example, the first threshold voltage is set to be 'battery voltage+2V' (namely, the increment is 2V), so that the first threshold voltage is 15V when the equipment is in a low electric quantity such as 13V, and is lower than the default energy supply threshold voltage by 18V, and the power adapter can be allowed to have larger instantaneous drop. As shown in fig. 4, when the power adapter is connected to the device, the power supply threshold voltage is reduced when the voltage is instantaneously drop, so that the problem that the power supply cannot be supplied because the voltage of the power adapter is below the power supply threshold voltage is avoided.
The threshold voltage adjusting module may, but not limited to, include a controllable current source, in this implementation manner, after the system controller obtains the current voltage of the battery module, determines a first threshold voltage value according to the current voltage of the battery module, and sends a threshold voltage adjusting instruction corresponding to the first threshold voltage value to the controllable current source, so as to control the controllable current source to change its output current, and implement adjustment of the energy supply threshold voltage value by changing its output current, so as to adjust the energy supply threshold voltage of the power adapter to the first threshold voltage.
Referring to the example of fig. 5 (a), a schematic diagram of electronic device system circuitry is provided that includes a first access terminal 11 for accessing a first type of power adapter and a second access terminal 12 for accessing a second type of power adapter.
The system circuit further comprises an energy supply main circuit, and the energy supply main circuit further comprises a power supply switch 21, a discharging switch 22, a charging switch 23, a power manager 30, a system controller 40 and a battery module 60. In addition, the system circuit further comprises a plurality of energy supply branches, such as a first energy supply branch 71 and a second energy supply branch 72 and … … in fig. 5 (a), and the connection relationship between the elements is shown in fig. 5 (a).
Referring to fig. 5 (a), compared with the prior art, in the embodiment of the present application, a threshold voltage adjusting module 50 is added in the above circuit structure, and is connected to the system controller 40 and the power manager 30, optionally, may be specifically connected to the power manager 30 through a voltage dividing resistor, when the power supply threshold voltage of the power adapter needs to be adjusted to be the first threshold voltage, the system controller 40 issues a corresponding adjustment instruction to the threshold voltage adjusting module 50, so as to implement adjustment of the power supply threshold voltage of the power adapter through the threshold voltage adjusting module 50, and synchronizes the adjusted threshold voltage information, such as the first threshold voltage, to the power manager 30, and the power manager 30 performs switch control on the power supply switch based on the adjusted power supply threshold voltage, such as the first threshold voltage, where if the voltage of the power adapter is lower than the first threshold voltage, the power supply switch is turned off, and otherwise, the switch is turned on.
Fig. 5 (b) provides an exemplary implementation of the circuit structure in fig. 5 (a), where P1 represents a first type of power adapter, such as a general purpose PD adapter, specifically, but not limited to, access 45-135W, P2 represents a second type of power adapter, such as a specific 300W adapter, and P2 represents a Battery module 60. The power supply switch 21 is specifically a back-to-back N-channel field effect transistor (q2a+q2b) in the figure, the discharge switch 22 is specifically an N-channel field effect transistor Q2C, the charge switch 23 is specifically an N-channel field effect transistor (q2d+q2e), the threshold voltage adjustment module is specifically a controllable current source U1, pm in the figure represents a power supply manager, EC (i.e., HOST) represents a system controller, the CPU represents a power supply branch for supplying power to the CPU in the figure, and the GPU represents a power supply branch for supplying power to the GPU in the figure. When the power supply threshold voltage of the power adapter needs to be adjusted to be the first threshold voltage, the system controller EC can specifically control the controllable current source U1 to change its output current, and adjust the power supply threshold voltage value by changing its output current, so that the power supply threshold voltage of the power adapter is adjusted to be the first threshold voltage, the power manager Pm detects the voltage value through its detection pin (ACDET in the figure), and performs power supply control on the power adapter based on the voltage value.
The setting of the preset condition is not limited to the above implementation, and in other embodiments, the preset condition may be set as follows: the load of the electronic device reaches a load threshold. Based on the condition, when the load of the electronic equipment reaches a load threshold, namely, the electronic equipment is in a heavy load state, the energy supply threshold voltage of the power adapter is adjusted, and the current threshold voltage value is reduced to a first threshold voltage, so that the problem that the equipment system cannot be supplied with energy due to the fact that the voltage of the power adapter is instantaneously reduced when the first type power adapter (such as the 45-135W universal standard PD adapter) is inserted into the equipment under the condition of heavy load of the equipment is avoided.
It is easy to understand that, in the case where the above-described preset condition is not satisfied, adjustment of the power supply threshold voltage of the power adapter is not performed at the electronic device.
In practical application, the preset condition can be, but not limited to, any one or more of the above two conditions, and by setting the preset condition, the power of the battery module in the electronic device is purposefully lower than a preset power threshold, and/or the power supply threshold voltage of the power adapter is adjusted in a heavy load state of the electronic device, so that the problem that the power supply system cannot be supplied to the device due to the instant reduction of the voltage of the power adapter when the first type of power adapter is plugged into the device under the conditions of no power of the battery, low power or heavy load of the device is avoided.
In an alternative embodiment, in a case that the type of the power adapter is the first type, the control method of the present application may further include:
a portion of a circuit in the electronic device is turned off, the portion of the circuit including the energy storage element.
Referring to fig. 6 (a), the above-mentioned partial circuit may be, but not limited to, a certain energy supply branch including an energy storage element, such as the second energy supply branch including an energy storage element 722 in fig. 6, where the energy storage element included in the energy supply branch may be specifically a capacitor, and in addition, a switching element 721 is further added to the energy supply branch in the embodiment of the present application, and the switching element 721 may be a controllable electronic switch, such as a Pmos tube. The powered down leg, such as the second powered leg in fig. 6 (a), may be, but is not limited to, the powered leg to which the independent graphics processor GPU corresponds.
Fig. 6 (b) shows a system circuit structure diagram after adding a switching element 721 on the basis of fig. 5 (b), where the switching element 721 is specifically Q1 in fig. 6 (b), and a capacitor in a GPU power supply branch is used for filtering, storing energy, and the like, and the main function of the capacitor is filtering, and because the energy storing characteristic of the capacitor consumes more electric energy, when it is determined that the type of the power adapter is the first type, in this embodiment, in addition to adjusting the power supply threshold voltage of the power adapter to be the first threshold voltage, the power supply branch of the electronic device is closed, and specifically, the power supply branch is closed by opening Q1.
Further, optionally, if the independent graphics processor is in a working state, the independent graphics processor is turned off first, and then the switching element Q1 is turned off after the independent graphics processor is turned off, so as to avoid system abnormality (such as blue screen) caused by directly turning off Q1 when the independent graphics processor is in the working state; if the independent graphic processor is in the non-operating state, the switching element Q1 of the independent graphic processor may be directly turned off.
In practical applications, when the type of the power adapter is the first type, other energy supply branches including the energy storage element in the electronic device can be disconnected according to the requirement, and the power supply branches are not limited to the energy supply branches of the independent graphics processor. It should be noted that, on the one hand, the disconnected energy supply branch has an energy storage capacitor, so that when the energy supply branch is disconnected, certain electric energy consumption can be further reduced for the equipment system, on the other hand, after the energy supply branch is disconnected, normal operation of the equipment system can be ensured, for example, after the energy supply branch of the independent graphics processor is disconnected, an integrated graphics card in the CPU of the electronic equipment can be used for carrying out required display processing.
Under the condition that the type of the power adapter is the first type, the embodiment can further avoid the problem that the power supply of the equipment system cannot be supplied due to the fact that the voltage of the power adapter is instantaneously reduced when the first type of the power adapter is inserted into the equipment under the conditions that the battery is not charged, the low power or heavy load is avoided under the condition that the equipment system is ensured to work normally by closing part of circuits in the electronic equipment.
In an alternative embodiment, the control method of the present application may further include, after causing the power adapter to power the electronic device with the power supply threshold voltage set by the first threshold voltage:
switching on the partial circuit;
and restoring the energy supply threshold voltage of the power adapter from the first threshold voltage to the default energy supply threshold voltage through the threshold voltage adjusting module.
Specifically, after the power adapter supplies power to the electronic device with the first threshold voltage, the switching element corresponding to the partial circuit is turned on, so that the partial circuit is turned on. For example, switching element Q1 of the independent graphics processor is turned on, and the power supply branch of the independent graphics processor is turned on by turning on Q1.
And the threshold voltage of the power adapter can be recovered from the first threshold voltage to the default threshold voltage by the threshold voltage adjusting module.
Preferably, after the power adapter supplies power to the electronic device with the first threshold voltage, the device components such as the system controller may continuously acquire the current voltage of the battery module of the electronic device according to the set time period, dynamically determine a new threshold voltage based on the acquired current voltage and the set voltage increment, continuously adjust the threshold voltage of the power adapter through the threshold voltage adjusting module such as a controllable current source, and synchronously lift the threshold voltage along with the continuous lifting of the voltage of the battery module until the threshold voltage is lifted to the default power supply threshold voltage of the power adapter, thereby completing the recovery of the default power supply threshold voltage.
The electronic equipment such as a notebook computer is generally provided with two modes, namely a charging mode (an adapter mode) and a battery mode, the threshold voltage of the power adapter is required to be higher than the highest voltage (such as 17.2V) of the battery, otherwise, the mode identification of the electronic equipment such as the notebook computer is disordered, and the power adapter supplies power to the electronic equipment by the first threshold voltage, so that the problem that energy cannot be supplied due to the fact that the voltage of the power adapter is instantaneously reduced below the energy supply threshold voltage is solved, the energy supply threshold voltage of the power adapter is timely restored to the default energy supply threshold voltage, and the influence on the mode identification of the electronic equipment can be avoided.
In an alternative embodiment, referring to the control method flowchart shown in fig. 7, the control method provided in the present application may further include:
In the case that the type of the accessed power adapter is identified as the second type, the embodiment directly controls the energy supply threshold voltage of the power adapter to be the default energy supply threshold voltage, and the power adapter correspondingly uses the default energy supply threshold voltage as the threshold to supply energy to the electronic device, for example, when the accessed power adapter is identified as the special 300W adapter, the power adapter can directly supply energy to the electronic device by using the default energy supply threshold voltage of 18V.
The second type of power adapter, its energy supply power is greater than or equal to the first total power of electronic equipment system, when inserting it into electronic equipment, can not exist because of the unable energy supply problem that the instantaneous voltage of power adapter reduces, this embodiment is through directly with defaulting energy supply threshold voltage control power adapter to the electronic equipment energy supply, can not produce such as unable energy supply scheduling problem.
In an alternative embodiment, the control method disclosed in the present application may further include:
and under the condition that the electric quantity of the battery module of the electronic equipment is zero, setting the energy supply threshold voltage of the power adapter to be a second threshold voltage, so that the power adapter can determine the type of the accessed power adapter after supplying energy to the electronic equipment by taking the second threshold voltage as the energy supply threshold voltage for a preset time.
Under the condition that the electric quantity of a battery module of the electronic equipment is zero, the embodiment of the application directly sets a threshold voltage value lower than the default energy supply threshold voltage of the power adapter, namely the second threshold voltage, for the power adapter, so that the power supply of the system of the electronic equipment can be successfully supplied to the system of the electronic equipment no matter what type of power adapter is connected to the power adapter in the follow-up process.
As shown in fig. 8 (a), in practical application, a switching element 24 may be but not limited to be connected between the battery module and the power manager, for example, a switching tube Qb may be connected to a detection pin ACDET of the power manager through voltage dividing resistors R1, R2, R3 by the switching element 24, and an exemplary connection relationship is shown in fig. 8 (b), where when the battery module is dead, i.e., the electric quantity is 0, the driving voltage of the switching tube Qb is not reached, qb is turned off, and the voltage of the detection pin ACDET on the power manager is the lower voltage set by dividing the R3 and R2, and the voltage is used as the second threshold voltage value, so as to set the power supply threshold voltage of the power adapter to the second threshold voltage when the electric quantity of the battery module is zero.
Subsequently, when the power adapter is connected to the device to enable the battery module to work, the driving voltage of the switching tube Qb is reached, qb is opened, the ACDET threshold voltage is higher voltage set by the partial voltage of R3, R2 and R1, and the threshold voltage can be adjusted by changing the output current of the controllable current source.
Optionally, a voltage dividing resistor may be further disposed between the switching tube Qb and the battery module to control the driving voltage of the switching tube Qb.
Optionally, an energy storage capacitor may be further disposed at an access end of the first type of power adapter in the electronic device, so that when the type of the power adapter is identified as the first type, the auxiliary electric quantity is provided for the power adapter to transmit electric energy to the electronic device by using the energy storage capacitor disposed at the access end of the power adapter.
Aiming at the condition that the electric quantity of the battery module is zero, after the power adapter is connected to the electronic equipment, the power adapter supplies power to the system for a preset time by taking the second threshold voltage as the power supply threshold voltage, and after the equipment has certain electric quantity and corresponding detection capability, the type of the connected power adapter is detected to identify whether the connected power adapter is of a first type or a second type.
And then, determining a recovery strategy for the default energy supply threshold voltage according to the identified type of the power adapter, and if the type is the first type, preferably adopting a gradual recovery strategy to recover the energy supply threshold voltage of the power adapter from the current second threshold voltage to the default energy supply threshold voltage, and if the type is the second type, directly recovering the energy supply threshold voltage of the power adapter from the current second threshold voltage to the default energy supply threshold voltage.
The embodiment of the application also discloses electronic equipment, which comprises: system circuitry and a controller.
Wherein, the controller is used for:
in response to detecting that a power adapter is accessed to a system circuit having a first total power, determining a type of the accessed power adapter;
