本发明提供的对接式充电电路与电子设备中，由于供电侧模块与接受侧模块在正接时可形成包含第一中间端、第二中间端、第一电阻线路等的第一回路，反接时则未形成第一回路，本发明可为正接与反接的判断提供电路依据，进而，结合供电侧驱动单元对第一开关单元的控制，可以在正接时控制第一开关单元导通，以实现供电，反接时控制第一开关单元关断，以避免反接时供电而导致对供电侧模块与接受侧模块中的器件造成损坏，起到了正反接判断及对应的安全保护作用。

本发明可选方案中，由于第一中间端对应触点的位置处于电压输出端对应触点与第一接地端对应触点之间的中点位置，第二中间端对应触点的位置处于电压输入端对应触点与第二接地端对应触点之间的中点位置，其可便于使得不论正接还是反接，两个中间端的触点均能够实现连接。
本发明可选方案中，由于接受侧驱动单元比较所述电压输入端的电压与预设的安全电压区间，并根据比较的结果控制所述第二开关单元的通断，且其中的安全电压区间是根据输入电压的过压保护点与最低欠压保护点确定的。其可以安全电压区间作为参考依据，判断当前的输入电压是否适于对电池进行充电，其可避免电压不适于充电时实施充电而造成对器件的损伤，进一步提高安全保护的作用。
本发明可选方案中，由于接受侧驱动单元的供电端连接了可以储能的电容，若所接入的电路模块未具有第一中间端，则无法使得电容被充电至所需电压，进而，接受侧驱动单元无法在电容的供电下实施控制，其可有利于避免被不适配的供电侧模块进行充电，进而避免了因此而可能造成的不安全充电。
本发明可选方案中，由于接受侧驱动单元的通讯端可利用第二中间端交互，其为指令沟通的机制提供了硬件基础。进一步的，由于接受侧驱动单元的通讯端可利用第二中间端实现认证请求与认证通过信号的交互，其可以进一步保障供电侧与接受侧的适配。
本发明可选方案中，结合电容的储能作用与通讯端的储能作用，可以使得接受侧模块未被供电时，接受侧驱动单元依旧能提供一定的电能来保障交互指令的交互。

其中，电压输出端15输出的电压可被表征为Vout，电压输入端24输入的电压可被表征为Vin，电源两端的电压可被表征为V1，其对应的向电压输出端15与赋电单元12输出的电压可被表征为Vee。
电池供电单元23，可被表征为：Battery-PoweredSystem，其可连接于电池，进而能够将电能供应至电池，以对其进行充电的电路单元，例如可以为能够实现线性充电、开关充电等方式的电路单元，任意方式的电池供电单元23均可理解为是对本实施例所涉及方案的一种实施。
供电侧模块1，可被表征为SourceSide，即源端；接受侧模块2，可被表征为SinkSide，即接受端。对于电子设备可以仅配置有供电侧模块1，从而为其他电子设备的充电进行供电，电子设备也可仅配置有接受侧模块2，从而被其他电子设备供电，从而实现充电，电子设备还可同时配置有供电侧模块1与接受侧模块2，进而可以为另一电子设备的充电进行供电，并可以被再一电子设备充电。
供电侧驱动单元14，根据其产生的作用，一种举例中，可以被表征为：IdentifyingIndicatingGateDriving。
本实施例中，所述供电侧模块1还包括供电侧驱动单元14、赋电单元12、第一开关单元13，以及第一中间端16，所述接受侧模块2还包括第二中间端25与第一电阻线路21。
所述赋电单元12连接于所述第一中间端16与所述电源12之间，以在所述电源11的供电下向所述第一中间端16输出目标电流；故而，赋电单元12在一种举例中可以包括电流源121，在另一种举例中可以包括分压单元，该分压单元可例如是通过电阻分压来实现的。可见，该目标电流可以是固定的电流值，也可以是变化的电流值。
所述第二中间端25连接所述第一电阻线路21的第一端，所述第一电阻线路21的第二端与所述第二接地端26一同接地。
所述电压输出端15对接所述电压输入端24，且所述第一接地端15对接所述第二接地端26时，所述赋电单元12、所述第一中间端16、所述第二中间端25、所述第一电阻线路22与地依次导通，形成第一回路，其可如图1所示。
所述第一开关单元13连接于所述电源11与所述电压输出端15之间，所述供电侧驱动单元14的采样端连接所述第一中间端16，所述供电侧驱动单元14的输出端连接所述第一开关单元13，所述供电侧驱动单元14用于根据所述第一中间端16的电压控制所述第一开关单元13的通断，以在形成所述第一回路时控制所述第一开关单元13导通，以及：在未形成所述第一回路的至少部分电路状态下控制所述第一开关单元13关断。
形成第一回路后，在目标电流的供电下，第一中间端16的理论电压应是一个第一电压值。该第一电压值可根据第一电阻线路21的压降数值和/或电阻数值、目标电流的电流值，以及电源对外输出的例如Vee的电压值确定。
其中一种实施方式中，若目标电流为固定的电流值，第一电压值为形成第一回路时的电压值，在未形成第一回路时，第一中间端16的电压会是不同于第一电压值的，通过判断所采集到的第一中间端16的电压值是否为第一电压值，或者判断其与第一电压值的差别是否小于阈值，可以判断当前是否形成第一回路，例如若第一中间端16的电压值为第一电压值，或者其与第一电压值的差值小于阈值，则确定形成了所述第一回路。
具体实施过程中，当第一电阻线路21可提供5.1KΩ的电阻，目标电流的电流值为固定的330μA，该第一电压值可以为1.68V。
另一种实施方式中，若目标电流为固定的电流值，在未形成第一回路时，则第一中间端16的电压会是不同于第一电压值的第二电压值，也可通过判断所采集到的第一中间端16的电压值是否为第二电压值，或者与第二电压值的差别是否小于阈值，判断当前是否处于非第一回路的其他电路状态，若是，即可推断当前并未形成第一回路。例如：若第一中间端16的电压值为第二电压值，或者其与第一电压值的差值小于阈值，则确定未形成所述第一回路。
具体实施过程中，若第一电压值为1.68V，且后文所涉及的第二回路中 的第二电阻线路22中的低正向压降二极管的正向电压为0.2V，第二电阻线路22提供100Ω的电阻，则该第二电压值可以例如为0.233V，其为形成第二回路时第一中间端16的理论电压。在可选实施过程中，也可针对于发生短路、连接外部导体等至少情况设计其他第二电压值，进而，可参照逻辑判断是否形成了第一回路。根据所考虑的情况不同，其具体的实现逻辑可以是多样的。
此外，也可同时结合第一电压值与第二电压值来实现判断。
可见，对是否形成第一回路的判断，可以是直接判断，也可以是间接判断。
再一种实施方式中，不论目标电流为固定的电流值还是变化的电流值，均可根据第一中间端16的电压值的变化来判断是否形成第一回路。例如在目标电流为固定的电流值时，可通过判断第一中间端16的电压值是否从第一电压值变化到了第二电压值，和/或判断是否从第二电压值变化到了第一电压值来判断是否形成了第一回路，具体举例中还可进一步判断未形成第一回路时，究竟是哪一种电路状态。
而其判断逻辑可以通过设置相应电路元件的参数值后通过电路原理的计算来确定一个可有利于表征第一回路时第一中间端16电压值正常范围的区间。若落在该区间，则可确定形成了第一回路。
以上各实施方式中，由于供电侧模块与接受侧模块在正接时可形成包含第一中间端、第二中间端、第一电阻线路等的第一回路，反接时则未形成第一回路，本发明可为正接与反接的判断提供电路依据，进而，结合供电侧驱动单元对第一开关单元的控制，可以在正接时控制第一开关单元导通，以实现供电，反接时控制第一开关单元关断，以避免反接时供电而导致对供电侧模块与接受侧模块中的器件造成损坏，起到了正反接判断及对应的安全保护作用。
同时，以上实施方式通过供电侧驱动单元对第一开关单元的控制，为对外的选择性供电提供了硬件基础，其可有利于避免不安全供电情形的发生，起到了对应的安全保护作用。例如，在可选方案中，若形成了第二回路、所述第一中间端未对外形成回路、部分端口发生短路，又或者部分端口与其他不适配的外部导体发生接触等情况，均可控制第一开关单元关断，以避免对不适配的接受侧模块进行充电，或者其他可能会造成不安全的情形。
其中一种实施方式中，请参考图1和图2，所述接受侧模块2还包括第二电阻线路22，所述第二中间端25还连接所述第二电阻线路22的第一端，所述第二电阻线路22的第二端连接至所述电压输入端24；所述电压输出端15对接所述第二接地端26，且所述第一接地端17对接所述电压输入端24时，所述赋电单元12、所述第一中间端16、所述第二中间端25、所述第二电阻线路22、所述电压输入端24、所述第一接地端17与地依次导通，形成第二回路。
故而，未形成所述第一回路的至少部分电路状态可以包括形成所述第二回路的电路状态。可见，供电侧模块1与接受侧模块2正接时，如图1所示，可形成第一回路，供电侧模块1与接受侧模块2反接时，如图2所示，可形成第二回路。
在形成第二回路时，可理解为发生了反接，供电侧驱动单元14可将第一开关单元13关断。
具体实施过程中，供电侧驱动单元14还可连接报警组件，以在形成第二回路，即发生了反接时，控制报警组件报警，该报警组件可以例如包括用于报警指示的发光二极管，控制器报警的方式可例如控制该发光二极管发光或者控制该发光二极管闪烁。
其中一种实施方式中，未形成所述第一回路的至少部分电路状态可以包括：所述第一中间端16未对外形成回路的电路状态；其可理解为第一中间端16对外空接时的电路状态。
进而，在第一中间端16对外空接时，供电侧驱动单元14可控制第一开关单元13关断，其可避免电压输出端15对外输出电而造成漏电等情况，进一步提高安全性。

进而，在端口发生短路时，可及时关断第一开关单元13，避免电流过大而造成过流损坏等情况，进一步提高了安全性。
其中一种实施方式中，未形成所述第一回路的至少部分电路状态可以包括：所述电压输出端15、所述第一中间端16、所述第一接地端17至少之一与所述接受侧模块以外的导体发生触碰的电路状态；未形成所述第一回路的至少部分电路状态可以包括：所述电压输入端24、所述第二中间端25、所述第二接地端26至少之一与所述接受侧模块1以外的导体发生触碰的电路状态。
进而，在端口对外触碰其他导体时，可及时关断第一开关单元13，避免电流过大而造成过流损坏等情况，进一步提高了安全性。
其中一种实施方式中，所述第一中间端16对应触点的位置处于所述电压输出端15对应触点与所述第一接地端17对应触点之间的中点位置，所述第二中间端25对应触点的位置处于所述电压输入端24对应触点与所述第二接地端26对应触点之间的中点位置。
其中，电压输出端15对应触点与第一接地端17对应触点之间的距离通常也与电压输入端24对应触点与第二接地端26对应触点之间的距离相同。
若该触点为接口中的金属触点，则可选择满足以上位置需求的触点作为中间端的触点，若该触点非接口中的触点，则可在触点的硬件设计时对中间端的触点位置进行配置，使其满足以上位置需求。

请参考图3，所述第一电阻线路21包括第一电阻R1，所述第一电阻R1的第一端连接所述第二中间端25，所述第一电阻R1的第二端与所述第二接地端26一同接地。
所述第二电阻线路22包括第二电阻R2与低正向导通压降二极管D1，所述低正向导通压降二极管D1的第一端连接至所述第二中间端25，所述低正向导通压降二极管D1的第二端连接至所述电压输入端24，所述第二电阻R2连接于所述低正向导通压降二极管D1与所述第二中间端25之间或者所述低正向导通压降二极管D1与所述电压输入端24之间。
具体实施过程中，在第一电阻线路21与第二电阻线路22中还可串联、并联有其他电阻。
图4是本发明实施例中一种对接式充电电路正接时的电路示意图三。
请参考图4，所述接受侧模块2还包括接受侧驱动单元28与第二开关单 元27。
所述第二开关单元27连接于所述电压输入端24与所述电池供电单元23之间，所述接受侧驱动单元28的采样端直接或间接连接所述电压输入端24，所述接受侧驱动单元28的输出端连接所述第二开关单元27，所述接受侧驱动单元28用于比较所述电压输入端的电压与预设的安全电压区间，并根据比较的结果控制所述第二开关单元27的通断，所述安全电压区间是根据输入电压的过压保护点与最低欠压保护点确定的，具体可例如：其中的安全电压区间，其下限为该最低欠压保护点，其上限为过压保护点。
该接受侧驱动单元28可产生保护作用，故而，根据其作用，可被表征为：ProtectionGateDriving或者GateDrivingProtection。
以上实施方式中，由于接受侧驱动单元比较所述电压输入端的电压与预设的安全电压区间，并根据比较的结果控制所述第二开关单元的通断，且其中的安全电压区间是根据输入电压的过压保护点与最低欠压保护点确定的。其可以安全电压区间作为参考依据，判断当前的输入电压是否适于对电池进行充电，其可避免电压不适于充电时实施充电而造成对器件的损伤，进一步提高安全保护的作用。
其中一种实施方式中，请参考图4，所述接受侧模块2还包括电容C1，所述接受侧驱动单元28的供电端连接所述电容C1的第一端，所述电容C1的第一端还连接所述第二中间端25，所述电容C1的第二端与所述第二接地端26一同接地。
由于接受侧驱动单元的供电端连接了可以储能的电容，若所接入的电路模块未具有第一中间端，则无法使得电容被充电至所需电压，进而，接受侧驱动单元无法在电容的供电下实施控制，其可有利于避免被不适配的供电侧模块进行充电，进而避免了因此而可能造成的不安全充电。
其中一种实施方式中，请参考图4，所述接受侧驱动单元28的通讯端口连接所述第二中间端25，以利用所述第二中间端25与供电侧模块1交互。
其中的通讯端口可被表征为输入输出端口，即I/O端口。
由于接受侧驱动单元的通讯端可利用第二中间端交互，其为指令沟通的机制提供了硬件基础，例如在未用于供电时实现指令的交互，其可以为进一步复杂的、多样的控制可能性提供基础，也可以为进一步的安全认证提供基 础。
所述接受侧驱动单元28具体可用于接收所述供电侧模块1的供电侧驱动单元14或其他电路单元发送的认证请求，并响应于所述认证请求返回认证通过信号，以使得所述供电侧模块1的供电侧驱动单元14能够根据所述认证通过信号控制所述第一开关单元的通断。
由于接受侧驱动单元的通讯端可利用第二中间端实现认证请求与认证通过信号的交互，其可以进一步保障供电侧与接受侧的适配。
在图4所示实施方式中，结合电容的储能作用与通讯端的储能作用，可以使得接受侧模块未被供电时，接受侧驱动单元依旧能提供一定的电能来保障交互指令的交互。
具体实施过程中，如果供电侧模块1向接受侧模块2供电需要更高的安全认证需求，供电侧模块1的供电侧驱动单元14或其他电路单元可以被配置为能够通过第一中间端16与第二中间端25发送相应的逻辑电平指令，其可理解为一种认证请求。接受侧驱动单元25可以通过通讯端口识别到该逻辑电平指令并进行响应，例如反馈认证通过信号，供电侧驱动单元14可根据接收到的信号，进一步可确定是否需要保持第一开关单元13导通，例如，若接收到认证通过信号，则控制第一开关单元13导通。
基于以上功能，接受侧驱动单元25具体可被表征为：ProtectionRespondGateDriving。

另一具体实施过程中，接收侧驱动单元28内部可配置有用于放置漏电的电路部分，故而，可不再设置第三场效应管FET3。
