图2示出了根据本公开的实施例的插座100的充电控制器130的示意性框图；以及
图3示出了根据本公开的实施例的插座100的交流/直流转换器120和电源控制器140的示意性框图。
在整个附图中，相同或相似的附图标记用于表示相同或相似的元件。
具体实施方式
以下结合一些实施例更详细地阐释本公开的技术方案。应当理解，这些实施例仅是为了更好地说明和理解本公开，而不是对本公开的限制。本领域技术人员在以下给出的实施例的基础上，可以对实施例的特征进行任意的组合和调整，这些都应当属于本公开的保护范围。
在本公开中，术语“包括”及其各种变体应理解为开放式术语，其表示“包括但不限于”。术语“基于”应理解为“至少部分地基于”。术语“一个实施例”应理解为“至少一个实施例”。术语“另一实施例”应理解为“至少一个其它实施例”。术语“第一”、“第二”等可以指代不同的或相同的对象。下文中还可能包括对其他术语的明确或隐含的定义。除非另有说明，术语的含义在本公开的上下文中是一致的。
图1示出了根据本公开的实施例的插座100的示意性框图。插座100例如可以是面板式插座、地插等，其具有壳体170来封装内部的各电气部件，以便防止触电风险。
在图1的示例中，插座100包括充电端口110，例如是USB端 口，其能够与待充电设备200例如智能电话、平板电脑等连接，并提供直流电压以对待充电设备200进行充电。
在图1的示例中，插座100还包括传统的插座端口150，其能够连接用电器300，以提供用电器300所需的交流工作电压。插座端口150例如可以是两孔插座端口、三孔插座端口和五孔插座端口中的任一种。
插座100还包括交流/直流转换器120、充电控制器130和电源控制器140。当充电端口110连接待充电设备200时，充电控制器130可以确定待充电设备200所支持的预期充电电压和预期充电电流，并且将相应的信息传输到电压控制器140。电源控制器140基于所确定的预期充电电压和预期充电电流，调整交流/直流转换器120的输出电压和输出电流。
通过这种方式，能够根据待充电设备200所支持的充电性能，准确地调节交流/直流转换器120的输出电压和输出电流，从而为不同规格的待充电设备200、尤其是支持快充功能的待充电设备200提供最佳的充电方案。由此能够缩短充电时间，提高充电效率。
另外，通过这种方式，无需在插座上为支持不同充电协议的移动设备分别提供专用的充电端口。换言之，在插座上仅需要提供一个充电端口，就可以满足不同充电设备的充电需求。由此能够节省制造成本，并且节省插座的内部空间，使得插座结构更紧凑。
在此，预期充电电压和预期充电电流可以是动态变化的。例如当待充电设备200的电池电量较低时，诸如低于电池电量的30％，待充电设备可以具有较高的预期充电电流，以便能够迅速地对电池进行充电。
随着电池电量的逐步增加，预期充电电流发生动态调整。当待充电设备200的电池电量达到较高的水平时，诸如高于电池电量的90％，待充电设备可以具有较低的预期充电电流，以便对电池进行保护避免过充。
应当理解，在此仅示例性地以预期充电电流为例进行了说明， 但是本公开不排除对预期充电电压进行相应地动态调节。
在某些实施例中，交流/直流转换器120连接电源控制器140和/或充电控制器130以提供工作电压。
通过这种方式，能够简化电路设计，无需为电源控制器140和充电控制器130另外设计工作电压供应电路。
在某些实施例中，充电端口110、交流/直流转换器120、充电控制器130和电源控制器140集成在充电模组160中，充电模组160可拆卸地安装在插座100中。
通过这种方式，能够模块化地设计插座100中的电气部件，使得用于为移动设备充电的直流部分与用于为用电器供电的交流部分彼此分开。当用于为移动设备充电的部件出现故障时，能够容易地进行拆卸，使得仅需要更换相应的充电模组160。
图2示出了根据本公开的实施例的插座100的充电控制器130的示意性框图。在图2的示例中，充电控制器130包括识别单元131、存储单元132以及确定单元133。
当待充电设备200连接到充电端口110时，识别单元131首先识别待充电设备200所支持的充电协议，例如是目前较为成熟的快充协议QuickCharge(QC)、USB Power Delivery Specification(PD)、VOOC闪充、Super Charge Protocol(SCP)和Fast Charging Protocol(FCP)等。
在存储单元132中，存储有多个充电协议所规定的预期充电电压和预期充电电流。例如USB Power Delivery Specification协议所支持的电压5V、9V、15V或20V和电流1.5A、2A、3A或5A等。
确定单元133基于识别单元131识别到的待充电设备200支持的充电协议，从存储单元132中找到对应的预期充电电压和预期充电电流，并将结果发送给电源控制器140。
电源控制器140基于所接收到的关于预期充电电压和预期充电电流的信息，调整交流/直流转换器120的输出电压和输出电流。例如当电源控制器140采用PWM控制方式时，可以根据预期充电电压 来调整占空比，从而将交流/直流转换器120的输出电压调整到预期的电压值。
可选地，充电控制器130还包括监视单元134。当交流/直流转换器120提供的实际充电电流超过预期充电电流达到预定阈值时，停止对待充电设备200提供输出电压和输出电流。预定阈值例如可以设定为待充电设备200的预期充电电流的10％至30％，或者其他适当的值。通过这种方式，能够有效地保护待充电设备200免受过电流。同时，还能避免插座由于过高的充电电流而导致过热损坏。
监视单元134还可以被配置为，当所识别的待充电设备200的预期充电电流超过交流/直流转换器120的额定电流时，将交流/直流转换器120的输出电流限定到额定电流。通过这种方式，能够有效地使交流/直流转换器120在安全的电流范围内工作，避免交流/直流转换器120由于过流或过热而损坏。
图3示出了根据本公开的实施例的插座100的交流/直流转换器120和电源控制器140的示意性框图。在图3的示例中，交流/直流转换器120被设计为包括变压器121、功率开关122、输入整流滤波器123和输出整流滤波器124。
输入整流滤波器123首先对交流输入信号进行整流及滤波，从而例如消除掉交流输入信号中冲击电流及浪涌电压等，以保护插座中的电气设备免受损坏。
功率开关122被耦合在变压器121的初级侧，并且受电源控制器140的控制。在例如PWM的控制方式下，电源控制器140基于待充电设备200的预期充电电压以及插座100的交流输入电压，而间断性地接通和断开功率开关122。变压器121例如是隔离变压器。
通过这种方式，能够调节变压器121初级侧的电压占空比，从而在变压器121的次级侧感应出符合待充电设备200的预期充电电压的电压值。
输出整流滤波器124对变压器121的次级侧所感应产生的电压进行进一步的整流与滤波，从而能够向待充电设备200提供基本恒 定的直流充电电压。
在图3的示例中，电源控制器140可以包括开关控制单元141。开关控制单元141与充电控制器130连接，并且基于充电控制器130所识别的待充电设备200的预期充电电压而接通(或关断)功率开关122，以调节输出电压。开关控制单元141例如可以采用PWM控制方式，基于预期充电电压与交流/直流转换器120的交流输入(在此例如为市电的220V)的比例来调整功率开关122的接通/断开时间，从而将交流/直流转换器120的输出电压调整到预期的电压值。
电源控制器140还可以包括温度感测单元142。温度感测单元142通过相应的传感器检测交流/直流转换器120的温度。当交流/直流转换器120的温度超过预定的温度阈值时，温度感测单元142向开关控制单元141发出相应的信息。开关控制单元141根据该信息而控制功率开关122断开，从而使交流/直流转换器120停止提供输出电压和输出电流。通过这种方式，能够为交流/直流转换器120提供过温保护，防止交流/直流转换器120由于温度过高而损坏。
应当理解，图3中的交流/直流转换器120和电源控制器140的实现方式仅仅是示例性的而非限定性的。本公开的实施例不排除交流/直流转换器120的其他实现方式。
还应当理解，本公开的实施例的充电控制器130和电源控制器140的各个功能单元例如能够以具有该功能的各种电路形式或其他硬件形式来实现，在此不做限制。
以上已经描述了本公开的各实施例，上述说明是示例性的，并非穷尽性的，并且也不限于所披露的各实施例。在不偏离所说明的各实施例的范围和精神的情况下，对于本技术领域的普通技术人员来说许多修改和变更都是显而易见的。本文中所用术语的选择，旨在最好地解释各实施例的原理、实际应用或对市场中技术的技术改进，或者使本技术领域的其它普通技术人员能理解本文披露的各实施例。
