Fig. 1 schematically shows a schematic diagram of a scenario in which an embodiment of the present disclosure is applicable.
As shown in fig. 1, a power adapter 110 is provided for the electronic device 100. When needed, the electronic device 100 is connected to a power adapter 110, and the power adapter 110 is in turn connected to an external power source 120. The external power source 120 is shown as a wall outlet. In fact, the external power source may also be other devices that provide power.
The electronic device 100 may be any electronic device, such as a tablet computer, a notebook, a microcomputer, an electronic book, an even internet protocol television box, a smart television, and the like, and can perform some operations in different states. For example, electronic devices such as tablet computers or notebooks are typically capable of being powered off when not in use, powered on when in use, and entering a standby state when not operated by a user for a long period of time after being powered on. As another example, an electronic device such as a network tv box is usually powered off when not in use, powered on when in use, and capable of performing a network search according to the user's requirement and feeding back the search result to the user, acquiring the resource selected by the user, and the like.
In the following description, a notebook is described as an example. Of course, those skilled in the art will recognize that the disclosed embodiments are not so limited.
Not shown in fig. 1, the electronic device 100 is generally equipped with a battery therein, and the battery is capable of charging and discharging. When the electronic device 100 is not connected to the power adapter 110, if the user turns on the electronic device 100 and the electronic device 100 enters the power-on mode, the battery is used to power various components operating in the electronic device 100. This consumes energy from the battery. If the electronic device 100 is connected to the power adapter 110 and the power adapter 110 is not connected to an external power source, the power adapter 110 is not operated and the electronic device 100 is still powered by the battery. If the power adapter 110 is connected to an external power source, the electronic device 100 is normally powered by the external power source. In this case, the power adapter 110 converts a current, usually an alternating current, from an external power supply into a direct current suitable for the electronic apparatus 100, and supplies the converted direct current to the electronic apparatus 100. In this case, the battery is in an idle state. Further, if the battery is not sufficiently charged, the charging circuit of the electronic device detects that the battery charge is lower than the set value, and the battery power adapter 110 is further used for charging the battery. That is, the power adapter charges the battery while supplying power to the electronic device. When the electric quantity of the battery reaches a set value, the power adapter stops charging the battery.
In order to increase the voltage of the battery, a plurality of batteries are generally connected in series to form a battery pack, two batteries are connected in series to form the battery pack and called as a 2S battery, and 3 batteries are connected in series to form the battery pack and called as a 3S battery. For example, if the rated voltage of a lithium battery is 3.6v and the charging voltage is 4.2v, the rated voltage and the charging voltage of a 2S battery are 7.2v and 8.4v, respectively, the rated voltage and the charging voltage of a 3S battery are 10.8v and 12.6v, respectively, and the rated voltage and the charging voltage of a 4S battery are 14.4v and 16.8v, respectively.
Typically, the power adapter outputs a fixed voltage. However, some power adapters, such as Thinkpad type-C power adapters, are currently available that are capable of outputting multiple voltages. The disclosed embodiments take advantage of this characteristic of the power adapter to improve charging efficiency.
Fig. 2 shows a flow diagram of a method 200 of charging a battery of an electronic device according to an embodiment of the disclosure.
As shown in fig. 2, the method 200 includes an operation S210 of connecting a power adapter (e.g., 110) to an external power source while being connected to the electronic device 100. Then, in operation S220, the state of the electronic device is determined. Finally, in operation S230, the voltage output by the power adapter to the electronic device is adjusted according to the state of the electronic device.
As described above, when the amount of power of the battery of the electronic device is insufficient, the power adapter supplies power to the electronic device using energy from the external power supply and charges the battery in the electronic device. Therefore, it is necessary to connect the electronic device to the external power source through the power adapter in operation S210.
The states it has are different for different electronic devices. For example, for a notebook computer, the states include a power-on state, a sleep state, a standby state, a power-off state, and the like. Electronic devices such as network television boxes also typically have an off state and an on state.
The electronic device is in different states, and the power consumption of the electronic device is different. For example, an electronic device in a power-on state consumes a large amount of energy because various components inside the electronic device need to operate normally. And because various components in the electronic equipment in the shutdown state do not work, the electronic equipment cannot consume energy. For the electronic device in the sleep state and the standby state, since most of its internal components do not operate, and only some components are kept operating so as to quickly recover the state of the electronic device before entering the sleep/standby state when the electronic device re-enters the boot mode (operating mode), the power consumption thereof is also low.
According to an embodiment of the present disclosure, determining the state of the electronic device in operation S220 includes detecting whether the electronic device is in a power-on state, a sleep state, a standby state, an operating state, a power-off state, or the like.
Then, in operation S230, the voltage output by the power adapter to the electronic device is adjusted according to the state of the electronic device.
Fig. 3 shows a flowchart of one example of operation S230 according to an embodiment of the present disclosure.
For one embodiment, if it is determined in operation S220 that the electronic device is in the power-on state, operation S230 includes operation S2302 of determining system power consumption and rated output of the power adapter. If it is determined that the system power consumption is less than the rated output of the power adapter, setting a voltage of the power adapter to be output to the electronic device to a voltage corresponding to a charging voltage of the battery in operation S2304; if it is determined that the system power consumption is not less than the rated output of the power adapter, the power adapter is set to output at a fixed voltage in operation S2306; if it is determined in operation S220 that the electronic device is not in the on state, operation S230 includes operation S2308 of reading information of a battery of the electronic device; and an operation S2310 of determining a voltage to be output to the electronic device according to the information of the battery.
As an example, if it is determined in operation S220 that the electronic device is in a power-on state, and it is determined in operation S2302 that the system power consumption is 45W, and the rated output of the power adapter is 65W or more (e.g., 90W), the voltage corresponding to the charging voltage thereof is generally 9V or 15V for, for example, a 2S battery in operation S2304, in which case the output of the power adapter may be set to 15V/3A, 9V/5A, or the like, in order to rapidly charge the battery through the power adapter and supply power for normal operation of the electronic device using the external power. For example, for a 3S battery, the output of the power adapter may be set to 20V/3.25A to quickly charge the battery.
As another example, if it is determined in operation S2302 that the system power consumption is 45W and the rated output of the power adapter is 45W, or even lower, e.g., 35W, the power adapter is set to output at a fixed voltage in operation S2306. For example, the power adapter outputs at 9V/5A for both 2S and 3S batteries.
As an example, if it is determined in operation S220 that the electronic device is not in a power-on state, for example, the electronic device is in a sleep state/hibernation state/power-off state, the method proceeds to operation S2308, where information of the battery is read.
In one embodiment according to the present disclosure, the information of the battery includes an attribute of the battery and a charging voltage corresponding to the attribute. In this case, operation S2310 includes setting a voltage to be output to the electronic device to the determined charging voltage.
For example, the battery may be a 2S, 3S or 4S battery. The charging voltage corresponding to the 2S battery may be 9V, the charging voltage corresponding to the 3S battery may be 15V, and the charging voltage corresponding to the 4S battery may be 20V. Accordingly, in operation S2310, the voltage to be output by the power adapter is set to 9V, 15V, or 20V for the 2S, 3S, or 4S battery, respectively.
In another embodiment according to the present disclosure, the information of the battery includes a real-time charging voltage of the battery. In this case, operation S2310 includes setting a voltage to be output to the electronic device as a sum of a charging voltage of the battery in real time and a predetermined difference.
For example, the charging circuit of the electronic device reads the real-time charging current value of the battery and transmits the acquired charging current value to the power adapter. The power adapter determines the real-time charging voltage of the battery according to the conversion of constant current-constant voltage (CC-CV) during the charging process. In an embodiment according to the present disclosure, a predetermined difference, for example 3V, is set. For example, if it is determined that the real-time charging voltage of the battery is 9V, the voltage to be output by the power adapter is set to 9V +3V, i.e., 12V in operation S2310. 12V output by the power adapter is converted into 9.V through the conversion of the charging circuit to charge the battery.
The predetermined difference value according to the embodiment of the present disclosure may be set according to actual conditions. For example, the predetermined difference may be set to, for example, 2.5V or 3.5V or the like for different kinds of electronic devices, specifically, for different charging circuits.
According to the embodiment of the disclosure, the output voltage of the power adapter is adjusted according to different states of the electronic equipment, so that the battery of the electronic equipment can be rapidly charged, and the charging efficiency is improved.
