电源设备是一种用于存储电能并在需要时为负载供电的装置。为了使电源设备能够在负载接入后的第一时间检测到负载并为之供电，传统的电源设备在开机后会一直保持供电电路处于开启状态，而供电电路处于开启状态时，供电电路内部的开关半导体会不可避免的产生开关损耗，因此会导致电源设备在空载时产生不必要的电能损耗，从而降低电源设备的电量储备和有效利用率。
为了降低电源设备空载时的电能损耗，传统方式是在检测到负载未连接至电源设备的输出端子时，将电源设备的有源部件关闭固定时间后再重新开启有源部件。然而，该方式会出现空载误判情况，从而无法实现及时供电，缩小了电源设备的适用范围。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请实施例提供的一种供电控制方法，执行主体为供电控制装置，该供电控制装置可以应用于电源设备，例如，移动储能设备。在具体应用中，供电控制装置可以设置在电源设备内部，也可以设置在电源设备外部并与电源设备连接，本申请实施例对供电控制装置的设置方式不做特别限制。以供电控制装置设置在电源设备内部为例，请参阅图1，图1为本申请实施例提供的一种电源设备的示意性架构图。如图1所示，电源设备10除了包括供电控制装置101之外，还可以包括直流电源102、直流-直流(direct current-direct current，DC-DC)转换电路103及交流-直流(alternating current-direct current，AC-DC)转换电路104。其中，DC-DC转换电路103连接在直流电源102与AC-DC转换电路104之间，DC-DC转换电路103用于对直流电源102提供的直流电进行电压转换并输出。AC-DC转换电路104用于对DC-DC转换电路103输出的直流电进行逆变并输出交流电。AC-DC转换电路104的输出端可以用于连接负载。
作为示例而非限定，DC-DC转换电路103可以为谐振变换电路。AC-DC转换电路104可以为功率因数校正(power factor correction，PFC)电路。DC-DC转换电路103和AC-DC转换电路104的具体结构可以根据实际需求设置，此 处对其不做特别限定。
本申请实施例中，DC-DC转换电路103和AC-DC转换电路104均与供电控制装置101连接。供电控制装置101可以通过对DC-DC转换电路103和AC-DC转换电路104进行控制，进而实现对电源设备10的供电控制。
在具体应用中，可以通过对供电控制装置配置目标脚本文件，由该目标脚本文件描述本申请实施例提供的供电控制方法，令供电控制装置在需要对电源设备进行供电控制时执行该目标脚本文件，进而执行本申请实施例提供的供电控制方法中的各步骤。
请参阅图2，为本申请实施例提供的一种供电控制方法的示意性流程图。如图2示，该供电控制方法可以包括S210～S220，详述如下：
S210：在第一供电控制模式下，基于多个连续的周期对电源设备进行供电控制，在每个周期的开启时段内开启电源设备的供电电路，在每个周期的关闭时段内关闭电源设备的供电电路。
其中，电源设备的供电电路指电源设备中用于向负载供电的电路。以图1所示的电源设备为例，电源设备的供电电路可以为由直流电源102、DC-DC转换电路103及AC-DC转换电路104组成的供电电路。在其他实施例中，电源设备的供电电路也可以采用其他结构，此处对供电电路的结构不做特别限定。
第一供电控制模式指控制电源设备的供电电路间断性工作的模式。基于此，第一供电控制模式对应的供电控制策略具体可以为：基于多个连续的周期对电源设备进行供电控制，具体地，在每个周期的开启时段内开启电源设备的供电电路，在每个周期的关闭时段内关闭上述供电电路。
在实际应用中，冰箱或空调等用电设备通常都具有静默工作模式，在静默工作模式下，这些用电设备的主功能模块会关闭，仅有控制器和一些传感器等处于工作状态，例如，冰箱在达到特定温度后会进入静默工作模式，在静默工作模式下，冰箱的制冷模块会关闭，仅保持控制器和温度计工作。因此，当电源设备的负载为此类具有静默工作模式的用电设备时，会导致供电控制装置有概率无法判断出电源设备是否带载，例如，如果冰箱刚好在每个周期的开启时段内进入静默工作模式，在每个周期的关闭时段内恢复正常工作模式，那么供电控制装置便识别不出有冰箱接入电源设备，即会认为电源设备未带载，从而造成空载误判的情况。
因此，为了能准确识别出具有静默工作模式的负载，本申请对多个连续的 周期中开启时段的时长和/或关闭时段的时长进行了改进，具体地，每个周期开启时段和关闭时段的时长之和等于每个周期的周期时长，而且，每个周期的周期时长是相同的，对于多个连续的周期中任意相邻的两个周期，后一个周期中开启时段的时长与前一个周期中开启时段的时长相差预设步长，即，预设步长用于描述任意相邻两个周期中，后一个周期的开启时段与前一个周期的开启时段之间的时长差。
需要说明的是，上述每个周期的时长、预设步长以及各个周期中开启时段的时长均可以根据实际需求设置。
示例性的，对于时间精度要求不高的负载，上述周期的时长可以为1秒，预设步长可以为0.1秒，第一个周期中开启时段的时长可以为0.1秒。基于此，第一个周期中关闭时段的时长为0.9秒；第二个周期中开启时段的时长为0.2秒，第二个周期中关闭时段的时长为0.8秒；第三个周期中开启时段的时长为0.3秒，第三个周期中关闭时段的时长为0.7秒，以此类推。
对于时间精度要求较高的负载，上述周期可以为0.1秒，预设步长可以为0.01秒，第一个周期中开启时段的时长可以为0.01秒。基于此，第一个周期中关闭时段的时长为0.09秒；第二个周期中开启时段的时长为0.02秒，第二个周期中关闭时段的时长为0.08秒；第三个周期中开启时段的时长为0.03秒，第三个周期中关闭时段的时长为0.07秒，以此类推。
本申请实施例中，供电控制装置进入第一供电控制模式的时机可以包括但不限于：(1)电源设备开机，且没有负载接入时；(2)电源设备开机，且有负载接入，且电源设备的节能模式处于开启状态，且未检测到负载电流时。
S220：在任意周期的开启时段内，在检测到负载电流的情况下，退出第一供电控制模式，进入第二供电控制模式，控制供电电路保持开启。
本申请实施例中，供电控制装置在基于多个连续的周期对电源设备进行供电控制的同时，还可以在每个周期的开启时段内对负载电流进行检测，即判断是否检测到负载电流。在本申请的一个实施例中，供电控制装置若在某个周期的开启时段内检测到负载电流，则说明该周期的开启时段内有负载接入电源设备，且该负载的实际需求功率不为0，即说明电源设备处于非空载状态，此时，供电控制装置退出第一供电控制模式，即供电控制装置不再执行基于多个连续的周期对电源设备进行供电控制的步骤，同时，供电控制装置进入第二供电控制模式。
其中，第二供电控制模式指控制电源设备的供电电路持续工作的模式，在第二供电控制模式下会控制供电电路保持开启。基于此，供电控制装置从第一供电控制模式切换为第二供电控制模式后，控制供电电路保持开启。
以上方案，由于在第一供电控制模式下，基于多个连续的周期对电源设备进行供电控制，在每个周期的开启时段内开启电源设备的供电电路，在每个周期的关闭时段内关闭供电电路，且后一个周期中开启时段的时长与前一个周期中开启时段的时长相差预设步长，即不同周期中的开启时段的时长是基于预设步长步进式变化的，例如，若负载的静默工作模式的触发时间是以0.1秒为精度的，则可以将预设步长设置为0.1秒，若负载的静默工作模式的触发时间是以0.01秒为精度的，则可以将预设步长设置为0.01秒，因此可以实现电源设备在不同周期的开启时段内识别出具有静默工作模式的负载，使得在此类负载接入的情况下，能够减少电源设备出现空载误判的情况，从而避免电源设备无法对误判的负载供电，确保满足各类负载的用电需求，扩大电源设备的适用范围。此外，由于仅在每个周期的开启时段内开启供电电路，在每个周期的关闭时段内关闭供电电路，因此可以降低电源设备的电能损耗，提高电源设备的有效利用率。
在本申请的另一个实施例中，供电控制方法还可以包括以下步骤：
在多个连续的周期的开启时段内，若均未检测到负载电流，则控制电源设备关机。
本实施例中，供电控制装置在基于多个连续的周期对电源设备进行供电控制时，若在多个连续的周期的开启时段内均未检测到负载电流，则说明在该多个连续的周期内均无负载接入电源设备，或者说明在该多个连续的周期内有负载接入电源设备，但接入电源设备的负载的实际需求功率较低，即说明电源设备处于空载状态，此时，供电控制装置控制电源设备关机。
以上方案，供电控制装置在多个连续的周期内均没有检测到负载电流时，说明电源设备处于空载状态，此时供电控制装置控制电源设备关机，可以避免电源设备在空载状态下处于工作状态，降低了电源设备的空载损耗。
请参阅图3，在本申请的又一个实施例中，供电控制方法还可以包括S320～S330，详述如下：
S320：在第一供电控制模式下，循环执行基于多个连续的周期对电源设备进行供电控制的步骤，并记录循环次数。
本实施例中，多个连续的周期的数量是有限的，多个连续的周期的数量可以根据实际需求设置，例如，可以为9。
因此，在第一供电控制模式下，供电控制装置基于多个连续的周期对电源设备进行完一次供电控制后，可以继续基于多个连续的周期对电源设备进行下一次供电控制，即，在第一供电控制模式下，供电控制装置可以循环执行基于多个连续的周期对电源设备进行供电控制的步骤。
供电控制装置循环执行基于多个连续的周期对电源设备进行供电控制的步骤时，可以记录该步骤的循环次数。
在一种可能的实现方式中，供电控制装置在循环执行基于多个连续的周期对电源设备进行供电控制的步骤时，还可以在每执行完一次该步骤后，检测一次是否有用电设备接入。在没有用电设备接入的情况下，将该步骤的连续循环执行次数加1，并继续执行下一次该步骤；在有用电设备接入的情况下，进一步确定是否检测到负载电流，在未检测到负载电流的情况下，将该步骤的连续循环执行次数加1，并继续执行下一次该步骤。
S330：在多个连续的周期的开启时段内，若均未检测到负载电流，且上述循环次数达到预设次数阈值，则控制电源设备关机。
本实施例中，若在多个连续的的周期的开启时段内均未检测到负载电流，则供电控制装置还判断上述步骤的循环次数是否达到预设次数阈值。在上述步骤的次数达到预设次数阈值的情况下，控制电源设备关机。
其中，预设次数阈值可以根据预先设置的第一供电控制模式的持续时长、多个周期的数量以及每个周期的时长确定。通过对第一供电控制模式的持续时长进行限定，可以避免电源设备在空载状态下一直处于第一供电控制模式，导致增加用电设备电能损耗。
示例性的，若预先设置的第一供电控制模式的持续时长为15分，多个周期的数量为9，每个周期的时长为1秒，那么执行一次基于多个连续的周期对电源设备进行供电控制的步骤需要9秒，15分可以循环执行100次该步骤，因此，预设次数阈值可以为100。
在其他实施例中，供电控制装置若在任一周期的开启时段内检测到负载电流，则可以进入第二供电控制模式，并基于负载的实际需求功率与电源设备的额定输出功率之间的实际比值对电源设备进行供电控制。需要说明的是，供电控制装置基于该实际比值对电源设备进行供电控制的具体过程可以参考后续实 施例中的相关描述，此处不进行赘述。
本实施例中，供电控制装置进入第二供电控制模式后，可以将上述步骤的循环次数重置为0。
以上方案，通过设置预设次数阈值，并在基于多个连续的周期对电源设备进行供电控制的步骤的循环次数达到该预设次数阈值时，控制电源设备关机，从而可以避免电源设备处于空载状态时，供电电路一直被间断性开启，进一步降低电源设空载时的电能损耗，提高电源设备的有效利用率。
请参阅图4，在本申请的又一个实施例中，在图2对应的实施例中的S210之前，或者在图3对应的实施例中的S320之前，供电控制方法还可以包括S410～S430，详述如下：
S410：检测是否有负载接入。
供电控制装置可以在电源设备开机后，检测是否有负载接入电源设备。
在一种可能的实现方式中，为了在负载接入时能够及时检测到负载，供电控制装置可以在电源设备开机后，实时检测是否有负载接入电源设备。
在另一种可能的实现方式中，为了降低电源设备的功耗，供电控制装置可以在电源设备开机后，每隔预设时间间隔检测一次是否有负载接入电源设备。其中，预设时间间隔可以根据实际需求设置，此处对其不做特别限定。
在又一种可能的实现方式中，为了实现对负载的有效检测，降低负载检测的误判率，电源设备上可以设置有用于检测负载是否接入的弹性部件，供电控制装置可以通过弹性部件的触发状态来判断是否有负载接入。
其中，弹性部件可以包括但不限于弹片、弹簧或弹针等。弹性部件的触发状态可以包括被触发和未被触发。
基于此，S410可以包括以下步骤：
检测弹性部件的触发状态；
若弹性部件被触发，则确定有负载接入；
若弹性部件未被触发，则确定无负载接入。
在一个实施例中，供电控制装置可以在检测到弹性部件被挤压时，确定弹性部件被触发；在检测到弹性部件未被挤压时，确定弹性部件未被触发。
在另一个实施例中，电源设备上还可以设置有与弹性部件相对应的触点。基于此，供电控制装置可以在检测到弹性部件与触点接触时，确定弹性部件被触发；在检测到弹性部件未与触点接触时，确定弹性部件未被触发。
需要说明的是，在电源设备开机后，供电控制装置可以先进入第二供电控制模式，在第二供电控制模式下，供电控制装置控制供电电路开启，控制供电电路将母线电压维持在额定电压值，即控制供电电路处于完全工作状态。其中，供电电路的母线电压可以指供电电路中的DC-DC转换电路输出的电压。额定电压值指电源设备的额定输出功率对应的电压值。
S420：若未检测到负载接入，则进入第一供电控制模式。
在一种可能的实现方式中，供电控制装置可以在检测到无负载接入电源设备时直接进入第一供电控制模式。
在另一种可能的实现方式中，供电装置在检测到无负载接入时，可以持续检测是否有负载接入，若在第三预设时长内检测到有负载接入，则供电控制装置进入第一供电模式；若在第三预设时长内均无负载接入，则供电控制装置控制电源设备关机。其中，第三预设时长可以根据实际需求设置，此处对其不做特别限定。
S430：若检测到负载接入，且电源设备的节能模式处于开启状态，且在负载接入后的第二预设时长内未检测到负载电流，则进入第一供电控制模式。
本实施例中，电源设备中预先配置有可供用户选择的节能模式。基于此，在负载接入电源设备的情况下，用户可以根据实际需求选择是否开启该节能模式。例如，用户可以在接入电源设备的负载为不具有静默工作模式的负载时，选择开启该节能模式，以降低电源设备的电能损耗。
可选的，用户可以通过操作与电源设备连接的终端设备(如，手机)中的模式选择控件来选择开启或关闭该节能模式。其中，模式选择控件为软件形式的按键，模式选择控件可以设置在终端设备安装的应用程序中。
可选的，用户还可以通过操作电源设备上设置的模式选择按钮来选择开启或关闭该节能模式。其中，该模式选择按钮为物理形式的按键。
基于此，供电控制装置可以在检测到有负载接入时，检测电源设备的节能模式是否处于开启状态，并确定是否检测到负载电流。
在一种可能的实现方式中，在有负载接入，且电源设备的节能模式处于开启状态时，若未检测到负载电流，则持续确定是否检测到负载电流。若在负载接入电源设备后的第二预设时长内均未检测到负载电流，则说明电源设备处于空载状态，此时供电控制装置进入第一供电控制模式。
其中，第二预设时长可以根据实际需求设置，此处对其不做特别限定。示 例性的，第二预设时长可以为300秒。
在另一种可能的实现方式中，在有负载接入，且电源设备的节能模式处于开启状态时，若检测到负载电流，则说明电源设备处于非空载状态，此时供电控制装置可以执行后续实施例中的S440～S470。
在又一种可能的实现方式中，在检测到负载接入，且电源设备的节能模式处于关闭状态的情况下，供电控制装置可以执行后续实施例中的S480。
以上方案，由于基于电源设备上设置的弹性部件的触发状态来确定是否有负载接入，因此可以提高负载接入检测的准确性；由于在无负载接入，或者有负载接入，且电源设备的节能模式处于开启状态，且在负载接入后的第二预设时长内未检测到负载电流时，说明电源设备处于空载状态，此时，供电控制装置进入第一供电控制模式，以控制供电电路间断性开启，因此可以降低电源设备空载时的电能损耗，提高电源设备的电量储备和有效利用率。
请继续参阅图4，在本申请的又一个实施例中，在S410之后，供电控制方法还可以包括S440～S470，详述如下：
S440：若检测到负载接入，且电源设备的节能模式处于开启状态，且检测到负载电流时，获取负载电流的电流值。
本实施例中，负载电流的电流值指流经负载的电流的值。
在一种可能的实现方式中，电源设备中还可以设置有用于采集负载电流的电流值的电流采集电路。作为示例而非限定，电路采集电路可以包括串联在负载回路中的电阻。
基于此，在有负载接入，且电源设备的节能模式处于开启状态，且检测到负载电流的情况下，供电控制装置可以从电流采集电路处获取其采集到的负载电流的电流值。
S450：根据负载的电流值确定负载的实际需求功率。
本实施例中，供电控制装置获取到负载电流的电流值后，可以根据该电流值计算负载的实际需求功率。其中，根据负载的电流值计算负载的实际需求功率的方式可以采用现有方式，此处不对其进行赘述。
S460：计算负载的实际需求功率与额定输出功率之间的实际比值。
本实施例中，供电控制装置可以将负载的实际需求功率与电源设备的额定输出功率的比值，确定为实际比值。
示例性的，假如负载的实际需求功率为9.3瓦特，电源设备的额定输出功 率为200瓦特，那么，供电控制装置将9.3/200＝4.65％确定为实际比值。如负载的实际需求功率为30瓦特，电源设备的额定输出功率为200瓦特，那么，供电控制装置将30/200＝15％确定为实际比值。
S470：开启供电电路，并根据实际比值与预设比值的大小关系，对供电电路的母线电压进行控制。
在一种可能的实现方式中，供电控制装置可以在检测到负载电流时便开启供电电路。该实现方式中，供电控制装置可以在开启供电电路的同时，获取负载电流的电流值，并确定上述实际比值；或者，供电控制装置可以在开启供电电路之后，获取负载电流的电流值，并确定上述实际比值。
在另一种可能的实现方式中，供电控制装置在检测到负载电流时，可以先获取负载电流的电流值，在基于负载电流的电流值确定出上述实际比值之后，再开启供电电路。本实施例对供电电路的开启时机不做特别限定。
本实施例中，供电控制装置得到实际比值后，可以将该实际比值与预设比值进行比较，以确定实际比值与预设比值之间的大小关系，并基于该大小关系对供电电路的母线电压进行控制。
其中，预设比值用于区分电源设备处于超轻载状态还是正常载量状态。在具体应用中，预设比值可以根据电源设备的应用场景的不同而不同。示例性的，预设比值可以为5％。基于此，假如实际比值为4.65％，由于4.65％小于5％，因此，供电控制装置可以控制供电电路将其母线电压降低；假如实际比值为15％，由于15％大于5％，因此，供电控制装置可以进入第二供电控制模式，在第二供电控制模式下，控制供电电路保持开启，控制供电电路将其母线电压维持在额定电压值。
具体地，当上述实际比值小于预设比值时，说明负载的实际需求功率较低，即说明电源设备处于超轻载状态；当上述实际比值大于或等于预设比值，说明负载的实际需求功率正常，即说明电源设备处于正常载量状态。
基于此，在一种可能的实现方式中，根据实际比值与预设比值的大小关系，对供电电路的母线电压进行控制的步骤，具体可以包括：
若实际比值小于预设比值，则控制供电电路将母线电压降低至第一预设电压值；
若实际比值大于或等于预设比值，则进入第二供电控制模式，控制供电电路保持开启。
其中，第一预设电压值小于上述额定输出功率对应的额定电压值。即在实际比值小于预设比值时，供电控制装置可以控制供电电路将DC-DC转换电路输出的电压值降低为第一预设电压值。
在本实施例中，在控制供电电路将DC-DC转换电路输出的电压值降低为第一预设电压值之后，本申请可以持续循环的进入S410，以检测负载的接入情况。
在本申请的所有实施例中，供电控制装置进入第二供电控制模式后，在控制供电电路保持开启的同时，还控制供电电路将母线电压维持在上述额定电压值，即控制供电电路处于完全工作状态。
本实施例中，供电控制装置在第二供电控制模式下，可以持续循环的进入S410，以检测负载的接入情况。
以上方案，在电源设备处于超轻载状态时，通过降低母线电压的电压值，从而可以降低一部分电源设备在超轻载状态下的电能损耗，提高电源设备的有效利用率。
请继续参阅图4，在本申请的又一个实施例中，在S410之后，供电控制方法还可以包括S480，详述如下：
S480：若检测到负载接入，且电源设备的节能模式处于关闭状态，则进入第二供电控制模式，控制供电电路保持开启。
本实施例中，在有负载接入，且电源设备的节能模式处于关闭状态的情况下，供电控制装置进入第二供电控制模式。
以上方案，由于在有负载接入，但电源设备的节能模式处于关闭状态时此时，进入第二供电控制模式，控制供电电路保持开启，使供电电路处于完全工作状态，从而确保供电电路可以为负载正常供电。
以下结合上述各个方法实施例以及图5，对本申请实施例提供的供电控制方法的整体控制逻辑进行详细说明：
如图5所示，电源设备开机后，供电控制装置进入S501。
S501：进入第二供电控制模式，控制电源设备的供电电路开启，控制供电电路将其母线电压维持在额定电压值。之后，供电控制装置进入S502。
