控制模块101确定第一主枪与第一从枪连接同一车辆，以及通过第一充电控制器102检测第一电压检测点电压为第三预设电压时，通过第一主枪和第一从枪对第一车辆进行充电。
其中，第一充电控制器102通过控制引导线连接第一充电枪104，当仅第一充电枪104与第一车辆连接时，第一充电控制器102通过第一充电枪104与第一车辆进行通信。第二充电控制器103通过控制引导线连接第二充电枪105，当仅第二充电枪105与第一车辆连接时，第二充电控制器103通过第二充电枪105与第一车辆进行通信。控制模块101根据第一充电枪104和第二充电枪105与车辆的通信情况控制第一充电枪104和第二充电枪105对第一车辆进行充电，当第一主枪和第一从枪对第一车辆进行充电时，第一充电控制器102根据第一充电枪104与车辆的通信情况调配第一充电枪104的输出功率，第二充电控制器103根据第一充电枪104的输出功率调配第二充电枪105的输出功率。充电桩10中还包括供电装置，供电装置分别与控制模块101、第一充电枪104、第二充电枪105连接，用于在控制模块101的控制下向第一充电枪104和第二充电枪105输出电源。
其中，控制模块可以通过通信交互设备接收用户的控制指令，例如接收用户设定的充电模式，控制模块还可以通过无线通信模块与远程服务中心通信，以接收控制指令，控制模块还可以通过设置计算程序计算使用充电桩的充电费用，控制模块具体可以为MCU(Microcontroller Unit；微控制单元)，充电模式为充电桩对车辆进行充电的方式，可以为“一车单枪”模式，即充电桩中的一个充电枪对车辆进行充电，也可以为“一车双枪”模式，充电桩中的两个充电枪对车辆进行充电。操作人员在充电桩10上设置充电模式为“一车单枪”模式，若只插第一充电枪104，则第一充电控制器102根据第一充电枪通信情况调配功率充电。若只插第二充电枪105，则第一充电控制器102根据第二充电枪105通信情况调配功率充电。操作人员在充电桩10上设置充电模式为“一车双枪”模式，控制模块101根据充电模式设置第一充电枪104为第一主枪，以及设置第二充电枪105为第一从枪，即采用第一充电枪104和第二充电枪105同时对车辆进行充电。第一主枪和第一从枪的区别在于在充电过程中第一主枪与第一车辆进行通信获取输出功率分配情况，第一从枪与第一车辆不通信，根据第一主枪与第一车辆的通信结果输出功率。
其中，第一电压检测点设置在第一充电控制器102与第一充电枪104之间的控制引导线上，第二电压检测点设置在第二充电控制器103与第二充电枪105之间的控制引导线上，根据第一电压检测点和第二电压检测点电压的检测可以判断第一充电枪104和第二充电枪105的充电状态。例如，第一充电控制器102与第一充电枪104之间的控制引导线和第二充电控制器103与第二充电枪105之间的控制引导线均连接12V电压，当在第一电压检测点检测到12V电平信号时，可判定第一充电枪104未连接车辆。当在第一电压检测点检测 到9V电平信号或者PWM信号时，可判定第一充电枪104已连接车辆。当在第一电压检测点检测到6V PWM信号时，可判定车辆已充电准备就绪或者第一充电枪104正在对车辆进行充电。故此，充电桩可通过同一条(CP)线，依靠电压9V、6V、方波变化，来实现插枪、充电、通信三者的判断和检测。
其中，控制模块101确定第一主枪与第一从枪连接同一车辆的方式有多种，可以是控制模块101通过第二充电控制器103接收到第一充电控制器102发送的通信信息时，确定第一主枪与第一从枪连接同一车辆。也可以是通过第一充电控制器102接收到第二充电控制器103发送的通信信息时，确定第一主枪与第一从枪连接同一车辆。也可以是通过第二充电控制器103接收到第一充电控制器102发送的通信信息，以及通过第一充电控制器102接收到第二充电控制器103发送的通信信息，确定第一主枪与第一从枪连接同一车辆。也可以是通过控制第一充电控制器102与第一充电枪104之间的控制引导线上电参数发生变化，并通过第二电压检测点检测该参数发生变化，确定第一主枪与第一从枪连接同一车辆。
举例而言，如图1和图2所示，当第一主枪与第一从枪连接同一车辆时，第二充电控制器103和第一充电控制器102最终会并联在一起，即CP与CP’最终在车辆端的EVCC201侧连接在一起，并形成一个回路。此时，控制模块101通过第一充电控制器102发送通讯信息时，最终可以在第二充电控制器103通道收到，由此在控制模块101通过第二充电控制器103接收到第一充电控制器102发送的通信信息时，确定第一主枪与第一从枪连接同一车辆。
其中，当满足以下三个条件时可以控制第一主枪和第一从枪对车辆进行充电：第一个条件是通过检测电压检测点电压确定第一主枪和第一从枪均与车辆连接。第二个条件是确定第一主枪与第一从枪连接同一车辆。第三个条件是检测第一电压检测点电压为第三预设电压时，判定车辆已充电准备就绪，通过第一主枪和第一从枪对第一车辆进行充电。通过设置上述三个条件，提升了充电桩对车辆进行充电的安全性。
本申请实施例一提供一种充电装置，充电装置包括：充电桩10、第一充电枪104和第二充电枪105，充电桩10包括控制模块101、第一充电控制器102以及第二充电控制器103，控制模块101根据充电模式设置第一充电枪104为第一主枪，以及设置第二充电枪105为第一从枪；控制模块101通过第一充电控制器102检测第一电压检测点电压为第一预设电压时，判定第一主枪与第一车辆连接，并通过第一充电控制器102控制第一主枪向第一车辆发送通信信息；控制模块101通过第二充电枪105检测第二电压检测点电压为第二预设电压时，判定第一从枪与第一车辆连接；控制模块101确定第一主枪与第一从枪连接同一车辆，以及通过第一充电控制器102检测第一电压检测点电压为第三预设电压时，通过第一主枪和第一从枪对第一车辆进行充电。本实施例中通过判定第一电压检测点电压、第二 电压检测点电压均满足预设电压，以及确定主枪与从枪连接同一车辆时，再通过主枪和从枪对第一车辆进行充电，避免了主枪和从枪连接不同车辆时进行充电导致出现安全隐患的问题，并且通过预先确定主枪和从枪，进而对主枪和从枪采用不同的控制策略，避免出现随机确定主枪和从枪导致充电失败的问题，使充电设备能够对车辆正常充电，并且提升了充电过程的安全性。
在一些实施例中，控制模块101确定第一主枪与第一从枪连接同一车辆，可包括以下三种实施例：
第一实施例，控制模块101检测到第二充电控制器103接收到第一充电控制器102发送的通信信息时，确定第一主枪与第一从枪连接同一车辆。
其中，当第一主枪和第一从枪连接同一车辆时，第一充电控制器102与第一充电枪104之间的控制引导线与第二充电控制器103与第二充电枪105之间的控制引导线在车辆中连接。因此，检测到第二充电控制器103接收到第一充电控制器102发送的通信信息，即可确定第一主枪与第一从枪连接同一车辆。通信信息可以是自定义通信信号，例如，某种序列的脉冲信号等。
第一实施例的技术效果在于：当检测第一主枪和第一从枪均连接车辆时，通过第一充电控制器102发送自定义通信信号，通过第二充电控制器103接收该自定义通信信号，实现了对第一主枪和第一从枪连接同一车辆的确定。
第二实施例，控制模块101检测到第一充电控制器102和第二充电控制器103均接收到对方发送的通信信息时，确定第一主枪与第一从枪连接同一车辆。
其中，当第一主枪和第一从枪连接同一车辆时，第一充电控制器102与第一充电枪104之间的控制引导线与第二充电控制器103与第二充电枪105之间的控制引导线在车辆中连接。因此，检测到第一充电控制器102和第二充电控制器103均接收到对方发送的通信信息时，确定第一主枪与第一从枪连接同一车辆。
第二实施例的技术效果在于：当检测第一主枪和第一从枪均连接车辆时，通过第一充电控制器102发送自定义通信信号，通过第二充电控制器103接收该自定义通信信号，通过第二充电控制器103发送自定义通信信号，通过第一充电控制器102接收该自定义通信信号，实现了对第一主枪和第一从枪连接同一车辆的确定。
第三实施例，充电桩还包括第一供电控制装置、第二供电控制装置、第一开关、第三开关、第一电阻以及第二电阻，第一供电控制装置连接第一开关的第一端，第一开关的控制端与控制模块连接，第一开关的第二端连接第一电阻的第一端，第一充电控制器102的一端与第一电阻的第二端形成的第一共接点通过第一控制引导线与第一充电枪连接，第一充电控制器102的另一端与第一充电枪的另一端连接，并在连接到车辆时连接到车辆地， 第一电压检测点位于第一控制引导线上，控制模块控制第一开关导通时，第一供电控制装置输出的电压在第一电阻上形成分压。

控制模块101控制第一开关在导通和关断之间进行切换，并检测到第二电压检测点的电压跟随第一开关的状态进行变化时，确定第一主枪与第一从枪连接同一车辆。
其中，当第一主枪和第一从枪连接同一车辆时，第一充电控制器102与第一充电枪104之间的第一控制引导线与第二充电控制器103与第二充电枪105之间的第二控制引导线在车辆中连接。因此，当在第一控制引导线上的电压发生变化时，可以在第二控制引导线上检测出该电压变化。
其中，第一供电控制装置和第二供电控制装置可以为电压转换器，将220V电压转化为5V直流电压或者12V直流电压，第一供电控制装置通过第一开关输出12V电源电压，当第一开关导通时，在第一电阻上形成分压，但是如果在第二控制引导线上的第二电压检测点检测到固定的电压值不能说明第一主枪和第一从枪连接在同一车辆上。因此，控制第一开关连续切换特定状态，在第二电压检测点检测到特定电压变化，确定第一主枪与第一从枪连接同一车辆。其中，第一开关连续切换特定状态可以是第一开关进行闭合断开的切换，从而若在第二电压检测点检测到与第一开关闭合断开对应的电压变化，则第一主枪和第一从枪形成同一个回路，从而可确定第一主枪与第一从枪连接同一车辆。
第三实施例的技术效果在于：当检测第一主枪和第一从枪均连接车辆时，通过控制第一开关连续切换特定状态，通过两电压检测点检测到特定电压变化，实现了对第一主枪和第一从枪连接同一车辆的确定。
作为一种实施方式，充电装置还包括第二开关，第二开关设于第二共接点与第二电压检测点之间；

其中，本实施方式中通过第一主枪与车辆通信，在确定第一主枪与第一从枪连接同一车辆时，通过断开第二开关使第二充电控制器103与车辆之间断开通信，以避免对第一主枪与车辆通信产生干扰。
在一些实施例中，控制模块101控制第一主枪和第一从枪对第一车辆进行充电时，通 过第一主枪与第一车辆进行通信，并根据通信结果对第一主枪和第一从枪的输出功率进行分配。
其中，第一充电控制器102通过第一主枪与车辆通信获取功率分配指令，并将该功率分配指令发送给控制模块101，控制模块101根据功率分配指令控制第一主枪和第一从枪输出对应功率。例如，控制第一主枪输出50％的功率，控制第一从枪输出50％的功率。

其中，如图4所示，充电桩包括第一SECC102、第一供电控制装置111、开关S1、电阻R1、电阻R3、第二SECC103、第二供电控制装置112、开关S2、电阻R2、电阻R4以及开关S3，第一供电控制装置111连接开关S1的切换端、电阻R3的第一端、接地端以及第一充电枪(未画出)，电阻R3的第二端连接第一充电枪，开关S1的控制端可与控制模块连接， 开关S1的另一端连接电阻R1的第一端，电阻R1的第二端连接第一SECC102以及第一充电枪，电阻R1的第二端与第一充电枪之间设有第一电压检测点A，第一SECC102连接接地端以及第一充电枪，第二供电控制装置112连接开关S3的切换端、电阻R4的第一端、接地端以及第二充电枪(未画出)，电阻R4的第二端连接第二充电枪，开关S3的控制端可与控制模块连接，开关S3的另一端连接电阻R2的第一端，电阻R2的第二端连接第二SECC103、开关S2的第一端，开关S2的第二端连接第二充电枪，第二SECC103连接接地端和第二充电枪，开关S2的第二端与第二充电枪之间设有第二电压检测点B，第一充电枪和第二充电枪连接第一车辆21中的第一EVCC211，第一EVCC211连接第一BMS212和第一供电模块213，第一供电模块213通过第一继电器215连接第一充电连接检测模块214。充电桩10还包括第三供电控制装置131、开关S4、电阻R5、电阻R6、第三SECC122、第四供电控制装置132、开关S5、开关S6、电阻R7、第四SECC123、电阻R8，第三供电控制装置131连接开关S4的切换端、电阻R7的第一端、接地端以及第三充电枪(未画出)，电阻R7的第二端连接第三充电枪，开关S4的另一端连接电阻R5的第一端，电阻R5的第二端连接第三SECC122以及第三充电枪，电阻R5的第二端与第一充电枪之间设有第三电压检测点C，第三SECC122连接接地端以及第三充电枪，第四供电控制装置132连接开关S6的切换端、电阻R8的第一端、接地端以及第四充电枪(未画出)，电阻R8的第二端连接第四充电枪，开关S6的另一端连接电阻R6的第一端，电阻R6的第二端连接第四SECC123、开关S5的第一端，开关S5的第二端连接第四充电枪，第四SECC123连接接地端和第四充电枪，开关S5的第二端与第四充电枪之间设有第四电压检测点D，第三充电枪和第四充电枪连接第二车辆22中的第二EVCC221，第二EVCC221连接第二BMS222和第二供电模块223，第二供电模块223通过第二继电器225连接第二充电连接检测模块224。

在此应用场景中，充电桩必须通过主枪的自定义信息检测配对的主枪和从枪是否同时连接到同一EVCC。若不进行检测，当有两辆车同时进行双枪充电，此时主枪和从枪配对错误(即第一主枪和第二从枪连接同一车，第二主枪和第一从枪连接另一车)，此时从枪只检测电压，则充电桩会判断四枪皆已连接好，充电桩开始输出能量，由于两车动力电池电压不相等，两车需求的充电电压也不相等，同一车上的两个充电枪输出电压不相等，很可能使充电回路上的接触器发生烧结。因此充电桩必须通过主枪的自定义信息检测配对的主枪和从枪是否同时连接到同一EVCC。
本实施方式中，当满足以下三个条件时可以控制第一主枪和第一从枪对第一车辆进行充电：第一个条件是通过检测电压电测点电压确定第一主枪和第一从枪均与车辆连接。第二个条件是确定第一主枪与第一从枪连接同一第一车辆。第三个条件是检测第一电压检测点电压为第三预设电压时，判定第一车辆已充电准备就绪，通过第一主枪和第一从枪对第一车辆进行充电。

本实施方式的技术效果在于：可以实现同一个充电桩对两辆车辆进行充电，同时避免了充电枪与车辆连接发生错误时，同一车上的两个充电枪输出电压不相等，很可能使充电回路上的接触器发生烧结的现象，提升了充电过程的安全性。
