目前的PD适配器一般都是两种接口存在，即USB A接口与USB C接口.从功能定义角度出发，对于PD适配器核心功能是PD快充。
本申请实施例提供的充电功率调整方法可以应用于电源适配器为多个电子设备同时 充电的场景。
针对电源适配器为多个电子设备同时充电的场景，假设包含5个充电端口的电源适配器为3个电子设备(分别为电子设备1、电子设备2、电子设备3)同时充电，由于在相关技术中，电源适配器的每个端口输出的功率值为提前预设好的，因此，电源适配器会根据提前预设的输出功率为每个电子设备充电，例如，端口1预设的输出功率为A，则电源适配器以功率值A为端口1的电子设备1充电，类似的，电源适配器也按照电子设备2和电子设备3的相应端口提前预设的输出功率为电子设备2和电子设备3充电。在上述过程中，电源适配器的实际可输出功率值通常远远大于上述3个端口提前预设的功率的加和值，但是，由于电源适配器的输出功率值为提前预设的，因此输出功率的过程会到限制，进而会导致浪费适配器的大量可利用的输出功率，并且降低电子设备执行充电任务的效率。
本申请实施例中，电源适配器在与3个电子设备连接的情况下，会接收到3个电子设备的3个功率请求信息(一个功率请求消息为接入上述电源适配器的一个电子设备向上述电源适配器发送的)，之后，该电源适配器会根据上述3个功率请求信息指示的功率的加和值与上述电源适配器的额定功率值，确定该3个电子设备的充电功率分配策略，最后，该电源适配器将按照上述充电功率分配策略，向3个电子设备分配充电功率。如此，电源适配器可以根据所有电子设备的实际功率的加和值来确定为每个电子设备分配的最终功率值，从而可以在保证电源适配器可靠性的前提下，最大程度的利用电源适配器的输出功率，从而提高电子设备执行充电任务的效率。
本实施例提供一种充电功率调整方法，如图1所示，该充电功率调整方法包括以下步骤301至步骤303：
步骤301：在M个电子设备与电源适配器连接的情况下，上述电源适配器接收上述M个电子设备发送的M个功率请求信息。
其中，M为正整数。
在本申请实施例中，一个功率请求信息与上述电源适配器连接的一个电子设备向上述电源适配器发送的。
在本申请实施例中，电子设备在接入电子设备适配器的端口后，会向电子设备发送功率请求信息，请求电源适配器为其分配功率，从而执行充电任务。
在本申请实施例中，不同的功率请求信息请求电源适配器分配的功率的功率值大小可能是相同，也可能是不同的。
在本申请实施例中，上述电源适配器可以包含N个端口，N大于等于M。
在本申请实施例中，上述电源适配器可以为PD适配器，上述电源适配器端口可以为USB接口。
步骤302：上述电源适配器根据上述M个功率请求信息指示的功率的加和值与上述电源适配器的额定功率值，确定充电功率分配策略。
在本申请实施例中，上述电源适配器在接收到M个功率请求信息指示的M个功率后，可以计算M个功率的加和值，并根据加和值与该电源适配器的额定功率值之间额大小关系，确定充电功率分配策略。
可以理解的是，当加和值大于该电源适配器的额定功率值时，电源适配器需要适当减小为每个电子设备分配的功率的功率值大小，当加和值小于或者等于该电源适配器的额定功率值时，电源适配器需要可以按照功率请求信息中请求的功率值为每个电子设备分配的功率。
在一种示例中，电源适配器可以提前设置多种不同的充电功率分配策略，在接收到电子设备的功率请求信息后，根据功率请求信息的功率值与额定功率值的大小关系，确定最终为电子设备分配功率时采用的充电功率分配策略。
在另一种示例中，电源适配器可以预设充电功率分配策略的判定条件，在接收到电子设备的功率请求信息后，根据功率请求信息的功率值与额定功率值的大小关系以及判定条件，确定最终为电子设备分配功率时采用的充电功率分配策略
步骤303：上述电源适配器按照上述充电功率分配策略，向M个电子设备分配充电功率。
可以理解的，向M个电子设备分配的充电功率可以相同，也可以不同。
本申请实施例提供的充电功率调整方法，在M个电子设备与电源适配器连接的情况下，会接收到M个电子设备发送的M个功率请求信息，之后，该电源适配器会根据上述M个功率请求信息指示的功率的加和值与上述电源适配器的额定功率值，确定该M个电子设备的充电功率分配策略，最后，该电源适配器将按照上述充电功率分配策略，向M个电子设备分配充电功率，M为正整数。如此，电源适配器可以根据所有电子设备的实际功率的加和值来确定为每个电子设备分配的最终功率值，从而可以在保证电源适配器可靠性的前提下，最大程度的利用电源适配器的输出功率，从而提高电子设备执行充电任务的效率。
可选的，在本申请实施例中，在上述步骤302中，本申请实施例提供的充电功率调整方法还可以包括如下步骤302a和步骤302b：
步骤302a：上述电源适配器在上述M个功率请求信息指示的功率的加和值小于或者等于上述电源适配器的额定功率值的情况下，确定上述充电功率分配策略为第一充电策略。
示例性的，上述第一充电策略为：根据上述M个功率请求信息对应的功率值，分别为上述M个电子设备分配充电功率。
可以理解的，电源适配器在上述M个功率请求信息指示的功率的加和值小于或者等于 上述电源适配器的额定功率值的情况下，电源适配器会根据M个电子设备中的每个电子设备向电源适配器发送的功率请求信息向该电子设备分配功率，也即所分配的功率的功率值即为电子设备发送的功率请求信息中请求的功率值。
示例性地，假设需要接入电源适配器的电子设备共有3个(即M为3)，分别为电子设备1，电子设备2，电子设备3，该电源适配器的额定功率值为200W，则电源适配器接收到3个电子设备发送的3个功率请求信息，该3个功率请求信息请求的功率值分别为50W、60W、40W，3个功率值的加和为150W，小于电源适配器的额定功率值200W(即M个功率请求信息指示的功率的加和值小于或者等于电源适配器的额定功率值)，则电子设备确定分配功率为按照各电子设备的功率请求信息中的功率值分配功率，即电子设备将为电子设备1分配功率50W，电子设备将为电子设备2分配功率60W，电子设备将为电子设备3分配功率40W。
步骤302b：上述电源适配器在上述M个功率请求信息指示的功率的加和值大于上述电源适配器的额定功率值的情况下，确定上述充电功率分配策略为第二充电策略。
示例性的，上述第二充电策略为：根据上述M个功率请求信息对应的功率值之间的比例关系以及上述额定功率值，分别为上述M个电子设备分配充电功率。
可以理解的，电源适配器在上述M个功率请求信息指示的功率的加和值大于上述电源适配器的额定功率值的情况下，电源适配器将比较上述M个功率请求信息对应的功率值之间的比例关系，并根据该比例关系划分额定功率值，得到每个电子设备对应的充电功率的功率值，并为上述M个电子设备分配充电功率。
示例性地，假设需要接入电源适配器的电子设备共有3个(即M为3)，分别为电子设备1，电子设备2，电子设备3，该电源适配器的额定功率值为200W，则电源适配器接收到3个电子设备发送的3个功率请求信息，该3个功率请求信息请求的功率值分别为100W、60W、80W，3个功率值的加和为240W，大于电源适配器的额定功率值200W(即M个功率请求信息指示的功率的加和值大于电源适配器的额定功率值)，则电源适配器将先计算3个功率请求信息请求的功率值之间的比例关系，分别为42％、25％、33％，则电源适配器将按照该比例划分额定功率值，将额定功率值划分为84W，50W和66W，并将上述划分好的3个功率值作为充电功率的功率值分配给3个电子设备，也即，电子设备将为电子设备1分配功率84W，电子设备将为电子设备2分配功率50W，电子设备将为电子设备3分配功率66W。
如此，电源适配器可以在接收到电子设备发送的功率请求信息后，可以将功率请求信息请求的功率值总和与电源适配器实际能分配的额定功率值进行比较，并按照实际能够分配的上限为每个电子设备分配额度最大的功率，从而在保证可靠性的前提下，最大程度的利用电源适配器所能够分配的功率。
可选的，在本申请实施例中，在上述步骤303之后，本申请实施例提供的充电功率调整方法还可以包括如下步骤304至步骤306：
步骤304：电源适配器接收上述M个电子设备中的目标电子设备发送的第一请求信息。
示例性的，上述第一请求信息用于请求上述电源适配器将为上述目标电子设备分配的充电功率值调整为目标功率值。
示例性的，上述第一请求信息为已经接入电源适配器的任意电子设备(即目标电子设备)，在需要改变当前接收的电源适配器的功率的情况下(例如需要提高充电功率)，向电源适配器发送的信息。
步骤305：电源适配器向上述M个电子设备中除上述目标电子设备以外的其他电子设备发送协商信息。
示例性的，上述协商信息用于确定是否允许调整所述其他电子设备的充电功率。
示例性的，上述协商信息为电源适配器在接收到第一请求信息后，向其他电子设备发送的询问其他电子设备是否同意改变自身充电功率的信息。
可以理解的，上述协商信息分别发送至每一个其他电子设备，则上述协商信息中指示的确定是否允许调整其他电子设备的充电功率，指的是：确定是否允许调整该个其他电子设备的充电功率。
步骤306：上述电源适配器在接收到第一电子设备确定信息情况下，调整上述第一电子设备的充电功率。
示例性的，上述其他电子设备包括所述第一电子设备。
示例性的，上述确定信息指示该第一电子设备允许上述电源适配器调整其充电功率。
能够理解的，不同的第一电子设备对应的充电功率不同，进一步地，无论是调整前还是调整后，不同的第一电子设备对应的充电功率均可以不同。
在一种示例中，电源适配器在接收到第一请求信息后，将会根据该第一请求信息请求的功率值，重新计算为每个电子设备分配的充电功率，并将该重新计算的能够为其他电子设备分配的充电功率以协商信息的形式告知其他电子设备。
第一：通常情况下，第一请求信息为电子设备请求电源适配器提高为其分配的充电功率，相应的，在为该电子设备提高分配的充电功率后，第一电子设备需要相应的减少分配的充电功率，从而为目标电子设备预留其需要提高的那部分充电功率。
第二，上述第一电子设备的确定信息可以为除了目标电子设备以外的部分电子设备，也可以为除了目标电子设备以外的全部电子设备发送的确定信息。
第三，在第一电子设备的确定信息为除了目标电子设备以外的部分电子设备发送的确定信息的情况下，在后续步骤307和步骤308中，电源适配器仅重新确定目标电子设备与 该部分电子设备(第一电子设备)的充电功率。
示例性的，电源适配器在接收到上述第一电子设备的确定信息后，将调整第一电子设备的充电功率，具体的，电子设备将重新确定充电功率分配策略，然后为第一电子设备分配充电功率，其中，该重新确定充电功率配策略的过程可以参照步骤302至步骤303的过程执行。
需要说明的是，上述重新确定充电功率配策略后，电源适配器可以为目标电子设备可以提高或者降低充电功率，但提高或者降低充电功率后，目标电子设备调整后的充电功率不一定为目标功率值，例如，电源适配器可以为目标电子设备可以提高充电功率，提高后的充电功率相较于当前目标电子设备的充电功率有所提高，但不一定能够与目标功率值相同。其中，电源适配器确定为目标电子设备可以提高或者降低充电功率的方式为：比较目标功率值与目标电子设备原先功率值的大小关系，若目标功率值大于目标电子设备原先功率值，则提高充电功率，若目标功率值大于目标电子设备原先功率值，则减小充电功率。
如此，在电源适配器接收到电子设备需要调整自身充电功率的情况下，可以向其他电子设备协商，并灵活调整所有电子设备或者部分电子设备的充电功率，使得电源适配器的功率得到灵活、充分地应用。
可选的，在本申请实施例中，在上述步骤305之后，本申请实施例提供的充电功率调整方法还可以包括如下步骤307：
步骤307：在上述电源适配器在预定时长内未接收到上述第二电子设备发送的确定信息情况下，保持上述第二电子设备的充电功率不变；
示例性的，上述第二电子设备为上述其他电子设备中未向电源适配器发送确定信息的电子设备。
示例性的，上述预定时长可以为电子设备预设的，也可以为用户自定义的，本申请实施例对此不作限定。
示例性的，在预定时长到达后，电源适配器仅调整向其发送确定信息的电子设备的充电功率，也即，仅调整第一电子设备的充电功率。
示例性地，如上述示例所述，假设电子设备1向电源适配器发送第一请求消息，请求电源适配器将其功率提高至80W，则此时，电源适配器将向电子设备2和电子设备3(即上述其他电子设备)发送协商信息，询问电子设备2和电子设备3是否允许调整电子设备2的功率值和电子设备3的功率值(即上述其他电子设备的充电功率)，在5秒内(即上述预定时长内)，电源适配器仅接收到了电子设备2(即上述第一电子设备)的确定信息，并未接收到电子设备3(即上述第二电子设备)的确定信息，则，电源适配器保持电子设备3的充电功率不变，同时将电子设备2的充电功率由60W调整至20W，同时将电子设备 1的功率值由50W调整至80W，也即，电子设备1的功率值为80W，电子设备1的功率值为20W，电子设备1的功率值为40W。
如此，在电源适配器需要根据目标电子设备的请求调整各个电子设备的功率值时，可以根据不同电子设备的不同需求机动、灵活的调整各个功率值，从而在最大程度上保证每个电子设备的实际功率需求。
可选的，在本申请实施例中，上述步骤306中的调整上述第一电子设备的充电功率，包括如下步骤306a和步骤306b：
步骤306a：电源适配器计算上述目标电子设备当前的功率值与上述目标功率值的第一差值。
步骤306b：电源适配器根据上述第一差值，调整上述第一电子设备的充电功率至第一充电功率。
可以理解的，上述第一充电功率与上述第一电子设备调整之前的充电功率之间的第二差值与上述第一差值相同。
上述目标功率值和第一电子设备可以参照前述描述，此处不再赘述。
示例性的，上述第二差值可以为所有第一电子设备与其所对应的第一充电功率之间的差值的加和值。
例如，共有3个电子设备，即电子设备1、电子设备2、电子设备3与电源适配器相连接，且3个电子设备的功率值加和与电源适配器的额定功率值相同。假设电子设备1为目标电子设备，其当前的功率值为50W，向电源适配器发送第一请求信息，请求将其功率值提高至70W(即目标功率值)，则电源适配器向电子设备2和电子设备3发送协商信息，电源适配器在接收到电子设备2和电子设备3(即上述第一电子设备)的确定信息后，将根据上述目标电子设备当前的功率值和目标功率值的差值20W(即上述第一差值)调整电子设备2和电子设备3的功率值，其中，电子设备2调整后的功率值与当前功率值的差值，以及电子设备3调整后的功率值与当前功率值的差值的加和为20W(即上述第二差值)。例如，可以将电子设备2的充电功率降低10W，并将电子设备3的充电功率也降低10W。
可以理解的，上述目标功率值大于上述目标电子设备当前的功率值的情况下，即目标电子设备需要提高充电功率的情况下，上述电源适配器降低上述第一电子设备的充电功率；上述目标功率值小于上述目标电子设备当前的功率值的情况下，即目标电子设备需要降低充电功率的情况下，上述电源适配器提高上述第一电子设备的充电功率。
可选的，在本申请实施例中，在上述步骤303之后，本申请实施例提供的充电功率调整方法还可以包括如下步骤308：
步骤308：上述电源适配器在X个电子设备已脱离上述电源适配器的情况下，根据(M-X) 个功率请求信息指示的功率的加和值与上述电源适配器的额定功率值间的大小关系，重新确定上述(M-X)个电子设备的充电功率分配策略，X为小于M的正整数。
示例性的，上述电源适配器在X个电子设备已脱离上述电源适配器的情况下，将回收上述X个电子设备的功率，并重新管理将上述回收的功率。
在一种示例中，电源适配器将重新计算能够为剩余(M-X)个电子设备分配的功率，即电源适配器将按照(M-X)个电子设备的功率请求信息中请求的功率值，为该(M-X)个电子设备重新分配功率。
在一种示例中，电源适配器将按照剩余(M-X)个电子设备之前功率分配的比值，将上述X个电子设备的功率分配给剩余(M-X)个电子设备。
示例性的，上述电源适配器重新确定所述(M-X)个电子设备的充电功率分配策略的过程可以参照步骤302至步骤303的过程进行执行。
如此，电源适配器可以在有电子设备从电源适配器脱离的情况下，及时将该脱离后空闲出的功率为其他还在电源适配器上充电的电子设备使用，从而充分利用电源适配器所能分配的功率。
可选的，在本申请实施例中，在上述步骤303之后，本申请实施例提供的充电功率调整方法还可以包括如下步骤309：
步骤309：上述电源适配器在X个电子设备已脱离上述电源适配器的情况下，将向(M-X)个电子设备发送询问信息。

示例性的，上述第三电子设备为(M-X)个电子设备中向电源适配器发送确认提高充电功率的信息的电子设备。
示例性的，上述电源适配器重新确定所述第三电子设备的充电功率分配策略的过程可以参照步骤302至步骤303的过程进行执行。
