Fig. 1 is a schematic diagram of an implementation environment of a method for adjusting output power according to an embodiment of the present application, referring to fig. 1, where the implementation environment includes a charger 100, the charger 100 includes a first charging port 101 and a second charging port 102, the first charging port 101 is controlled by a first chip 103, the second charging port 102 is controlled by a second chip 104, for example, the first chip 103 can control the output power of the first charging port 101, and the second chip 104 can control the output power of the second charging port 102. In the embodiment of the present application, the first chip 103 and the second chip 104 are both fast charging protocol chips, and the second chip 104 is capable of sending information to the first chip 103.

After describing the implementation environment of the embodiment of the present application, an application scenario of the technical solution provided in the embodiment of the present application will be described below in conjunction with the implementation environment, where in the following description process, the charger is that of the charger 100 in the implementation environment, the first charging port is that of the first charging port 101 in the implementation environment, the second charging port is that of the second charging port 102 in the implementation environment, the first chip is that of the first chip 103 in the implementation environment, and the second chip is that of the second chip 104 in the implementation environment.

The technical scheme that this application embodiment provided can be applied in the in-process that uses the charger to charge to intelligent terminal, and this charger has first mouth and the second mouth of charging. After the technical scheme provided by the embodiment of the application is adopted, in the process of charging the intelligent terminal by using the first charging port of the charger, the second charging port of the charger is used for charging other intelligent terminals, the first chip adjusts the output power of the first charging port to be preset power, and the preset power is the difference between the maximum output power of the charger and the preset maximum output power of the second charging port. Since the maximum output power of the charger is the sum of the preset maximum output power of the first charging port and the preset maximum output power of the second charging port, the first chip adjusts the output power of the first charging port to the preset power, so that the second charging port can charge with the maximum output power. The first chip determines a first reference power level of the second charging port, wherein the first reference power level is used for representing the output power of the second charging port when the second charging port is stably charged. The first chip adjusts the output power of the first charging port based on a target parameter, wherein the target parameter comprises the first reference power level, and the charging power of the first charging port is dynamically adjusted on the premise of ensuring that the second charging port is charged with proper charging power, so that the dynamic adjustment of the output power of the charger is realized.

After the implementation environment and the application scenario of the embodiments of the present application are described, the following describes the method for adjusting the output power provided by the embodiments of the present application, and referring to fig. 2, the technical solution provided by the embodiments of the present application is applied to a charger, where the charger includes a first chip and a second chip, the first chip is used to control a first charging port of the charger, and the second chip is used to control a second charging port of the charger, and the method includes the following steps.

201. Under the condition that a first charging port of a charger is in a charging state, responding to a second charging port of the charger to enter the charging state, the first chip adjusts the output power of the first charging port to be preset power, and the preset power is the difference between the maximum output power of the charger and the preset maximum output power of the second charging port.

The first charging port being in a charging state means that the first charging port is charging, that is, the first charging port is outputting power outwards, or an intelligent terminal connected with the first charging port and charging through the first charging port exists. The second charging port enters the charging state, namely, the second charging port enters from the uncharged state to start charging. The output power of the first charging port is the charging power when the first charging port is charged. Since the maximum output power of the charger is constant, increasing the output power of the first charging port results in a decrease in the available charging power of the second charging port, which is the charging power that the second charging port can provide when charging. The charging power of the first charging port is adjusted to be preset power, so that the second charging port can be ensured to be charged with the preset maximum output power, namely the theoretical maximum output power of the second charging port in design.

202. The second chip sends the power level of the second charging port to the first chip.

The power level is used to indicate the magnitude of the output power, and the first charging port and the second charging port both have the concept of power level, but the correlation between the output power of the first charging port and the output power of the second charging port and the power level is opposite, for example, in the case that the output power of the first charging port is inversely correlated with the power level, the output power of the second charging port is positively correlated with the power level. Correspondingly, the power level of the second charging port is used for reflecting the output power of the second charging port.

203. The first chip determines a first reference power level of the second charging port based on the power level of the second charging port sent by the second chip, where the first reference power level is used to represent the magnitude of output power when the second charging port is stably charged.

Wherein, the stable charging of the second charging port means that the output power of the second charging port is kept constant for a period of time.

204. The first chip adjusts the output power of the first charging port based on a target parameter, the target parameter including a first reference power level of the second charging port.

The first reference power level of the second charging port can reflect the output power of the second charging port when the second charging port is stably charged, so that the output power of the first charging port is adjusted based on the target parameter comprising the first reference power level, the maximum output power of the charger can be utilized to the maximum extent, and reasonable distribution of the output power is realized. In some embodiments, the target parameter may include an output power of the second charging port in addition to the first reference power level of the second charging port.

The foregoing steps 201 to 204 are a simple introduction of the method for adjusting output power provided in the embodiments of the present application, and the technical solution provided in the embodiments of the present application will be described more clearly with reference to some examples, and referring to fig. 3, the technical solution provided in the embodiments of the present application is applied to a charger, where the charger includes a first chip and a second chip, the first chip is used to control a first charging port of the charger, and the second chip is used to control a second charging port of the charger, and the method includes the following steps.

301. The first chip determines a charging state of the second charging port of the charger when the first charging port of the charger is in a charging state.

The charging state is used for describing the charging condition of the charging port, and the first charging port being in the charging state means that the first charging port is charging, that is, the first charging port is outputting power outwards, or an intelligent terminal connected with the first charging port and charging through the first charging port exists.

In some embodiments, the preset maximum output power of the first charging port is greater than the preset maximum output power of the second charging port, that is, in the case that two charging ports of the charger are a combination of USB-Type a and USB-Type C, the first charging port is a USB-Type C port, the second charging port is a USB-Type a port, the USB-Type a port is generally used for charging devices with smaller power, such as a mobile phone, a tablet computer, etc., and the USB-Type C port is generally matched with a USB-PD universal protocol, so that the battery charger can charge the mobile phone, the tablet computer, the notebook computer, both power supply for high-power devices and charging for low-power devices. Or, under the condition that two charging ports of the charger are USB-Type C and USB-Type C combinations, the first charging port is a USB-Type C port with larger preset maximum output power, and the second charging port is a USB-Type C port with smaller preset maximum output power.

In one possible implementation, the first chip obtains an initial power level of the second charging port. And under the condition that the initial power level is larger than the first preset power level, the first chip determines that the second charging port of the charger enters a charging state, and the first preset power level corresponds to the theoretical minimum output power of the second charging port. And under the condition that the initial power level is equal to the first preset power level, the first chip determines that the second charging port of the charger does not enter a charging state, and the first chip acquires the initial power level of the second charging port again.

Wherein the power class, also referred to as power state class, is a simplified description of the output power. For the first charging port, the different power levels correspond to different maximum output powers of the first charging port; for the second charging port, the different power levels correspond to different maximum output power and output power ranges for the second charging port. The corresponding relation between the power level and the maximum output power of the first charging port and the corresponding relation between the power level and the output power range of the second charging port are set by a technician according to actual conditions, and the first chip and the second chip respectively store the corresponding relation. The first preset power level is set by a technician according to practical situations, which is not limited in the embodiment of the present application. Accordingly, the theoretical minimum output power of the second charging port refers to the maximum power output by the second charging port when the second charging port is not used for charging. That is, at the first preset power level, the second charging port is not in a charging state. In the embodiment of the present application, for the second charging port, the higher the power level, the higher the output power, that is, the power level is positively correlated with the output power. The preset time period refers to a time period for continuously acquiring the power level of the second charging port, and the length of the preset time period is set by a technician according to actual conditions, which is not limited in the embodiment of the present application.

In this embodiment, the initial power level of the second charging port is obtained, and the charging state of the second charging port can be determined by comparing the initial power level with the first preset power level, so that the charging state is high in efficiency.

For example, the first chip obtains an initial power level of the charging port from the second chip, and accordingly, the initial power level is a power level of the second chip sent to the first chip in the preset period, and in some embodiments, the second chip sends the power level of the second charging port to the first chip with a preset period, for example, the second chip sends the power level of the second charging port to the first chip at the end of each period, so that the power level of the second charging port is more accurate. The first chip compares the initial power level with a first predetermined power level. And under the condition that the initial power level is larger than the first preset power level, the first chip determines that the second charging port of the charger enters a charging state.

In order to more clearly illustrate the technical solution described in the above example, a method for determining the power level of the second charging port by the second chip is described below.

In some embodiments, the second chip determines the current of the second charging port at the end of each cycle. The second chip determines the output power of the second charging port based on the current and voltage of the second charging port. The second chip determines the power class of the second charging port based on the output power of the second charging port. Of course, after the second chip determines the power level of the second charging port, the power level of the second charging port can be announced to the outside, that is, the power level of the second charging port is broadcasted, so that the first chip can obtain the power level of the second charging port. The period of determining the power level of the second charging port by the second chip is set by a technician according to the actual situation, which is not limited in the embodiment of the present application.

The first chip determines the charging state of the second charging port periodically, which is described above by taking the first chip determining the charging state of the second charging port as an example, and the process of determining the charging state of the second charging port by the first chip in two consecutive periods will be described below with reference to fig. 4 and 5.

Fig. 4 is a flowchart of the second chip determining the power level of the second charging port, and referring to fig. 4, in the case where the power level of the second charging port is determined for the first time, the second chip performs power-up initialization on the second charging port. The second chip sets the default power level of the second charging port to 0. The second chip broadcasts that the power level of the second charging port is 0. The second chip sets a timing t1, which timing t1 is the duration of a period that determines the power level of the second charging port. In the case where the timing t1 does not end, the second chip remains waiting. When the timing t1 ends, the second chip determines the current of the second charging port. The second chip determines the output power of the second charging port based on the current and voltage of the second charging port. The second chip determines the power class of the second charging port based on the output power of the second charging port. After determining the power level of the second charging port, the second charging port broadcasts the power level of the second charging port. After the second chip broadcasts the power level of the second charging port, it enters the next cycle of determining the power level of the second charging port.

Fig. 5 is a flowchart of determining the charging state of the second charging port by the first chip, referring to fig. 5, in the case where the charging state of the second charging port is determined for the first time, the first chip initializes the first charging port to be powered on, defines the power level of the second charging port as pl_a, defines the power level of the first charging port as pl_c, and defines the power of the first charging port as pwr_c. The first chip sets initial values for parameters pl_ A, PL _c and pwr_c, that is, pl_a=0, pl_c=0, and pwr_c=pmax_c, where 0 is a first preset power level and pmax_c represents a preset maximum output power of the first charging port. The first chip sets a timing t2 to acquire an initial power level pl_a of the second charging port. In the case that the initial power level pl_a of the second charging port is the same as the first preset power level 0 of pl_c, it means that the second charging port is not in a charged state, and the first chip re-acquires the initial power level of the second charging port. If the initial power level pl_a of the second charging port is different from the first preset power level 0 of pl_c, determining whether the initial power level pl_a of the second charging port is greater than the first preset power level 0 of pl_c, and if the initial power level pl_a of the second charging port is greater than the first preset power level 0 of pl_c, determining that the second charging port enters a charging state, and executing the subsequent step of adjusting the output power of the first charging port.

The following describes, with reference to table 1, the correspondence between the power levels and the output power of the first charging port and the output power of the second charging port, respectively, taking the maximum output power of the charger as an example of 67.5W.

TABLE 1

Power class	PNMAX_A/W	PNMAX_C/W	PSYS/W
				0	2.5	65	67.5
1	5	62.5	67.5
				2	7.5	60	67.5
3	10	57.5	67.5
				4	12.5	55	67.5
5	15	52.5	67.5
				6	17.5	50	67.5
7	20	47.5	67.5
				8	22.5	45	67.5

In table 1, pnmax_a represents the maximum output power of the second charging port, pnmax_c represents the maximum output power of the first charging port, and PSYS represents the maximum output power of the charger, and PSYS does not change for the same charger. As can be seen from table 1, as the power level increases, the maximum output power of the second charging port increases, and the maximum output power of the first charging port decreases, i.e., the power level is inversely related to the maximum output power of the first charging port and positively related to the output power of the second charging port.

302. And in response to the second charging port entering a charging state, the first chip adjusts the output power of the first charging port to be preset power, wherein the preset power is the difference between the maximum output power of the charger and the preset maximum output power of the second charging port.

Wherein, the second charging port enters the charging state, which means that the second charging port starts charging from the uncharged state. The output power of the first charging port is the charging power when the first charging port is charged. Since the maximum output power of the charger is constant, increasing the output power of the first charging port results in a decrease in the available charging power of the second charging port, which is the charging power that the second charging port can provide when charging. The charging power of the first charging port is adjusted to be preset power, so that the second charging port can be guaranteed to be charged with preset maximum output power, the preset maximum output power is the theoretical maximum output power of the second charging port in design, namely the theoretically maximum available charging power of the second charging port, the preset maximum output power of the first charging port and the preset maximum output power of the second charging port are set by technicians according to the hardware structure of the charger, and the embodiment of the application is not limited to the above. In addition, the output power of the first charging port is adjusted to be preset power, so that when the second charging port is charged, the sum of the output powers of the first charging port and the second charging port is smaller than or equal to the maximum output power of the charger, and the safety of the charger is guaranteed.

In one possible implementation manner, in a case that the preset maximum output power of the first charging port is greater than the preset maximum output power of the second charging port, the first chip reduces the output power of the first charging port to the preset power through a preset protocol in response to the second charging port entering the charging state.

In this embodiment, when the second charging port is in the charging state, the output power of the first charging port can be reduced to the preset power, and the charging performance of the second charging port with a lower preset maximum output power can be preferentially ensured.

For example, when the preset maximum output power of the first charging port is greater than the preset maximum output power of the second charging port, the first chip adjusts the power level of the first charging port to a second preset power level in response to the second charging port entering the charging state, adjusts the output power of the first charging port to a preset power, the second preset power level corresponds to the preset power, and the second preset power level is the available output power of the first charging port when the second charging port charges at the preset maximum output power.

For example, referring to fig. 5, in case that the initial power level pl_a of the second charging port is greater than the first preset power level 0 of pl_c, the first chip determines that the second charging port enters the charging state. The first chip adjusts the power level pl_c of the first charging port to a second preset power level pl_max, and adjusts the output power pwr_c of the first charging port to a preset power pmin_c, where pl_max is power level 8 in table 1, and corresponds to the minimum maximum output power 45W of the first charging port, taking the power level shown in table 1 as an example.

303. The second chip sends the power level of the second charging port to the first chip.

The power level is used to indicate the magnitude of the output power, and the first charging port and the second charging port both have the concept of power level, but the correlation between the output power of the first charging port and the output power of the second charging port and the power level is opposite, for example, in the case that the output power of the first charging port is inversely correlated with the power level, the output power of the second charging port is positively correlated with the power level.

In one possible implementation, the second chip determines the power class of the second charging port based on the output power of the second charging port. The second chip sends the power level of the second charging port to the first chip.

In this embodiment, the second chip is capable of determining the power level of the second charging port based on the output power of the second charging port, and transmitting the power level of the second charging port to the first chip, so that the first chip can dynamically adjust the power based on the power level of the second chip.

For example, the second chip determines the current of the second charging port. The second chip determines the output power of the second charging port based on the current and voltage of the second charging port. And the second chip queries based on the output power of the second charging port to obtain the power class of the second charging port. After the second chip determines the power level of the second charging port, the power level of the second charging port can be announced outwards, so that the purpose of sending the power level of the second charging port to the first chip is achieved.

304. The first chip determines a first reference power level of the second charging port based on the power level of the second charging port sent by the second chip, where the first reference power level is used to represent the magnitude of output power when the second charging port is stably charged.

In one possible implementation, if the first chip acquires the same power level from the second chip N times in succession within a preset period of time, the first chip determines the same power level as the first reference power level of the second charging port, and N is a positive integer.

And a period of time exists between the second charging port entering the charging state and the stable charging, in which the output power of the second charging port may change greatly, and after the second charging port enters the stable charging, the output power of the second charging port is stable, and the preset period of time is to wait for the second charging port to enter the stable charging state after the period of time elapses.

In this embodiment, the first chip may determine, as the first reference power level, the power level of the second charging port obtained continuously N times in the preset period, and wait for the preset period to enable the second charging port to enter a stable charging state, so that the accuracy of subsequently adjusting the output power of the first charging port is higher.

For example, referring to fig. 5, after the first chip adjusts the power level pl_c of the first charging port to the second preset power level pl_max and adjusts the output power pwr_c of the first charging port to the preset power pmin_c, the first chip re-determines the power level pl_a of the second charging port to be the first reference power level.

On the basis of the above embodiment, optionally, if the first chip does not acquire the same power level from the second chip for N consecutive times within the preset period of time, the first chip resets the preset period of time and reacquires the power level of the second charging port, so as to cycle until the first chip acquires the same power level for N consecutive times within the preset period of time.

305. The first chip adjusts the output power of the first charging port based on a target parameter, the target parameter including a first reference power level of the second charging port.

The first reference power level of the second charging port can reflect the output power of the second charging port when the second charging port is stably charged, so that the output power of the first charging port is adjusted based on the first reference power level, the maximum output power of the charger can be utilized to the maximum extent, and reasonable distribution of the output power is realized.

In one possible implementation, the first chip determines a target power level of the first charging port based on a first reference power level of the second charging port, the target power level being the same as the first reference power level of the second charging port, the power level of the first charging port being inversely related to the output power, and the power level of the second charging port being positively related to the output power. The first chip adjusts the output power of the first charging port to the power corresponding to the target power level.

And when the power level of the first charging port is the same as that of the second charging port, the sum of the output power of the first charging port and the output power of the second charging port is the maximum output power of the charger. That is, when the power level of the first charging port is adjusted to be the same as that of the second charging port, the output power of the charger can be ensured to be fully utilized, and the charging efficiency can be improved.

In this embodiment, the power level of the first charging port can be adjusted to be the same as that of the second charging port, so that the charger can fully exert charging performance when the first charging port and the second charging port output power corresponding to the target power level and power corresponding to the first reference power level, respectively, and intelligent distribution of charging power of the charger can be realized.

For example, the first chip adjusts the power level of the first charging port to the same target power level as the first reference power level. The first chip determines a target output power corresponding to the target power level, and adjusts the output power of the first charging port to the target output power.

For example, referring to fig. 5, after the first chip re-determines the power level pl_a of the second charging port to be the first reference power level, the first chip compares the power level pl_c of the first charging port with the first reference power level. In the case where the power level pl_c of the first charging port is greater than the first reference power level, the first chip determines the power level pl_c of the first charging port as the same target power level as the first reference power level. The first chip adjusts the output power of the first charging port to the output power corresponding to the target power level.

In one possible implementation, the first chip adjusts the output power of the first charging port based on a first reference power level of the second charging port and a required charging power of a charging device connected to the first charging port.

The charging device connected to the first charging port, that is, the device that charges through the first charging port, the required charging power of the charging device refers to the charging power that the charging device can need when charging the charging device, that is, the protocol charging power of the charging device, where the required charging power of the charging device is configured by a manufacturer of the charging device, and can be sent to the first chip when connected to the first charging port. The charging device is also the intelligent terminal described before.

Under this kind of embodiment, can combine first reference power class and the demand charging power of battery charging outfit to adjust the output of first mouth that charges, realize the accurate control to first mouth that charges.

For example, the first chip determines a target power level of the first charging port based on a first reference power level of the second charging port, the target power level being the same as the first reference power level of the second charging port. The first chip adjusts the output power of the first charging port based on the target power level of the first charging port and the required charging power of the charging device.

For example, the first chip adjusts the power level of the first charging port to the same target power level as the first reference power level. The first chip determines a target power corresponding to a target power level of the first charging port. And under the condition that the required charging power of the charging equipment is larger than or equal to the target power, the first chip adjusts the output power of the first charging port to the target power. And under the condition that the required charging power of the charging equipment is smaller than the target power, the first chip adjusts the output power of the first charging port to be the required charging power of the charging equipment.

In one possible implementation, the first chip adjusts the output power of the first charging port based on the first reference power level of the second charging port, the maximum output power of the charger, and scaling parameters between the power level and the output power of the second charging port.

The conversion parameter between the power level of the second charging port and the output power is used for converting the power level of the second charging port into the output power of the second charging port.

In this embodiment, the output power of the first charging port is adjusted based on the conversion parameters between the first reference power level, the maximum output power of the charger, and the power level and the output power of the second charging port, so that the output power of the first charging port can be intelligently adjusted.

For example, the first chip determines the output power of the second charging port based on the first reference power level of the second charging port and a scaling parameter between the power level and the output power of the second charging port. The first chip subtracts the maximum output power of the charger from the output power of the second charging port to obtain the target output power of the first charging port. The first chip adjusts the output power of the first charging port to the target output power.

For example, the first chip multiplies the first reference power level of the second charging port by a conversion parameter between the power level of the second charging port and the output power to obtain the output power of the second charging port. The first chip subtracts the maximum output power of the charger from the output power of the second charging port to obtain the target output power of the first charging port. The first chip adjusts the output power of the first charging port to the target output power.

Taking the conversion parameter between the power level of the second charging port and the output power as 2.5, the first reference power level as 3, and the maximum output power of the charger as 65W as an example, the first chip multiplies the conversion parameter between the first reference power level 3 of the second charging port and the power level of the second charging port and the output power as 2.5 to obtain the output power of the second charging port as 7.5W. The first chip subtracts the maximum output power 65W of the charger from the output power 7.5W of the second charging port to obtain the target output power 57.5W of the first charging port. The first chip adjusts the output power of the first charging port to the target output power of 57.5W.

Optionally, after step 305, the first chip is further capable of performing any one of

steps

306 and 307 described below.

306. In the case that the power level of the second charging port is changed from the first reference power level to a second reference power level, the first chip adjusts the output power of the first charging port based on the second reference power level.

The power level of the second charging port is changed from the first reference power level to the second reference power level, which means that the charging stage of the second charging port is changed, and the end of the charging process may be entered, and the output power of the second charging port may be reduced, thereby causing the power level of the second charging port to be changed from the first reference power level to the second reference power level.

In one possible implementation, in a case where the power level of the second charging port is changed from the first adjusted power level to a second reference power level, the first chip determines the adjusted power level of the first charging port based on the second reference power level of the second charging port, the adjusted power level being the same as the second reference power level of the second charging port. The first chip adjusts the output power of the first charging port to the power corresponding to the adjusted power level.

For example, the first chip adjusts the power level of the first charging port to the same adjusted power level as the second reference power level. The first chip determines the target output power corresponding to the adjustment power level, and adjusts the output power of the first charging port to the target output power.

In one possible implementation, the first chip adjusts the output power of the first charging port based on the second reference power level of the second charging port and the required charging power of the charging device connected to the first charging port.

For example, the first chip determines an adjusted power level of the first charging port based on a second reference power level of the second charging port, the adjusted power level being the same as the second reference power level of the second charging port. The first chip adjusts the output power of the first charging port based on the adjusted power level of the first charging port and the required charging power of the charging device.

For example, the first chip adjusts the power level of the first charging port to the same adjusted power level as the second reference power level. The first chip determines the adjusting power corresponding to the adjusting power level of the first charging port. And under the condition that the required charging power of the charging equipment is larger than or equal to the adjusting power, the first chip adjusts the output power of the first charging port to the adjusting power. And under the condition that the required charging power of the charging equipment is smaller than the adjustment power, the first chip adjusts the output power of the first charging port to the required charging power of the charging equipment.

307. And under the condition that the second charging equipment is connected with and disconnected from the second charging port of the charger, the first chip adjusts the output power of the first charging port to the required charging power of the charging equipment.
