充电配对方法、装置、电子设备、系统及存储介质
本申请要求申请日为2021年4月8日、申请号为202110379182.8的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及车辆技术领域，例如涉及一种充电配对方法、装置、电子设备、系统及存储介质。
背景技术
电动汽车无线充电，是一种新型充电技术，它不借助充电线材即可实现对一定空间范围内的车辆持续充电。电动汽车无线充电实现的方法主要是基于无线电能传输(Wireless Power Transfer)技术，利用磁谐振耦合、激光、微波等原理将电能以非接触的方式由电网端传送到用电设备端，可以实现用电设备的无线充/供电，具有安全可靠、灵活便捷、环境友好、可全天候工作等诸多优点，近年来受到了广泛的关注，无线充电系统在启动功率传输之前需要先完成配对。
相关技术中的配对技术通常采用车辆的身份标识(Identity，ID)或者识别号码(Vehicle Identification Number，VIN)作为配对过程中的关键参考量，然而该类技术在应用于多个连续车位设置有无线充电地面设备的场景时，无法准确配对，会存在车辆与相邻充电车位的地面设备误连接而与相邻车位的地面设备误配对，即配对过程成功而配对效果失效的情况。
为保证车辆与当前充电车位中的地面设备有效配对，相关的技术方案往往需要增加相关的硬件来实现，如充电车位的地面设备和车辆分别需增加射频的发射端和接收端，但这会导致系统的成本大幅增加，而额外增加设备会增加系统的体积与重量，使得系统结构复杂化。
另外，相关技术中的配对技术还容易出现无线充电过程中电气参数超限，例如功率变换环节的阻抗过低，进而导致系统设备中某个环节过热或器件损坏的情况，存在安全问题。

具体实施方式
本申请中，应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。同时，在本申请的描述中，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
图1为本实施例提供的充电配对方法的一个流程示意图，该方法可以由实施例提供的充电配对装置来执行，该装置可采用软件和硬件中的至少一种方式实现。在一个具体的实施例中，该装置可以集成在电子设备中，电子设备比如可以是充电车位上的地面设备，该地面设备可以是用户指定的用来给当前车辆充电的地面设备。以下实施例将以该装置集成在电子设备中为例进行说明，参考图1，该方法具体可以包括如下步骤：
步骤101，在基于目标配对信息与车辆进行匹配后，开启异物检测板。
在一实施例中，目标配对信息可以包括车辆ID、VIN码以及电子设备ID等，当在车辆端选择好通信服务时，车辆可以向电子设备发送车辆ID、VIN码等，电子设备可以根据车辆ID、VIN码与车辆进行参数匹配；与此同时，电子设备可以向车辆发送电子设备ID，以使得车辆根据电子设备ID与电子设备进行参数匹配，在双方的参数匹配均成功时，电子设备可以开启自身已有的异物检测器。
步骤102，利用异物检测板检测车辆。
通过实验可知，当车辆进入用户指定充电车位时，该充电车位的电子设备的异物检测板检测到的电压信号会存在较大的幅值增加与差异，比如图2所示，异物检测板检测到的电压信号会有明显跳变，因而可以利用电子设备的异物检测板检测当前的充电车位上是否有车辆，以确保车辆与指定充电车位上的电子设备建立通信连接。
步骤103，确定是否检测到车辆，若检测到车辆，则执行步骤104，若未检测到车辆，则执行步骤105。
步骤104，向车辆发送配对成功通知信息。
即本申请实施例中，在电子设备与车辆基于常规的配对信息进行匹配之后，还会将车辆作为金属异物，通过电子设备的异物检测板进行异物检测，只有在检测到当前车辆时，才会认为配对成功，才会向车辆发送配对成功通知信息。
步骤105，向车辆发送配对失败通知信息。
本申请实施例中，在基于目标配对信息与车辆进行匹配后，会开启异物检测板，利用异物检测板对车辆进行检测，若检测到车辆，则向车辆发送配对成功通知信息，若未检测到车辆，则向车辆发送配对失败通知信息。即本申请实施例中，会利用异物检测板做配对的补充检测，以此提高配对准确率，避免无效配对；另外，由于异物检测板是电子设备的现有部件，因而本申请实施例并没有新增设备，不会增加系统成本和结构复杂度。
在一实施例中，比如图3所示，当前车辆进入充电车位，用户指定当前车辆要利用充电车位的电子设备1对当前车辆充电，充电车位与充电车位相邻，充电车位上具有电子设备2，当前车辆在通信握手时，如果未与电子设备1建立无线通信连接(WIFI 1)，而是与电子设备2建立了无线通信连接(WIFI 2)，那么电子设备2的异物检测板将检测不到当前车辆，所以即使当前车辆与电子设备2建立了无线通信连接，无线充电系统不会启动功率传输。这种情况下，当前车辆可以退出充电车位，改而进入充电车位，从而启动无线充电系统进行功率传输；或者当前车辆可以断开与电子设备2的无线通信连接(WIFI 2)，改而与电子设备1进行无线通信连接(WIFI 1)，从而启动无线充电系统进行功率传输。
下面进一步说明本实施例提供的充电配对方法，如图4所示，本实施例的方法可以包括如下步骤：
步骤201，接收车辆发送的第一配对信息，第一配对信息中包括第一配对码和第一电气兼容参数。
在一实施例中，第一配对信息中可以包括第一配对码和第一电气兼容参数，其中，第一配对码可以 包括车辆ID或VIN码，第一电气兼容参数可以包括：车载设备的功率等级、离地间隙、工作频率、输出电压范围中的至少一者。在一实施例中，结合图5，车辆可以根据用户操作选择通信服务，比如选择无线通信服务，在选择通信服务之后，车辆可以启动配对流程，向电子设备发送第一配对信息。
步骤202，基于第一配对码与车辆进行配对，并基于第一电气兼容参数对车辆进行兼容性校验。
步骤203，向车辆发送第二配对信息，第二配对信息中包括第二配对码和第二电气兼容参数，以使得车辆基于第二配对码与电子设备进行配对并基于第二电气兼容参数对电子设备进行兼容性校验。
在一实施例中，第二配对信息中可以包括第二配对码和第二电气兼容参数，第二配对码可以包括电子设备ID，第二电气兼容参数可以包括电子设备的功率等级、可支持的离地间隙、工作频率中的至少一者。比如图5所示，电子设备在接收到车辆发送的第一配对信息之后，可以启动配对流程，基于第一配对信息中的第一配对码与车辆进行配对，并基于第一电气兼容参数对车辆进行兼容性校验，与此同时，可以向车辆发送第二配对信息。
步骤204，在配对成功且兼容性校验成功时，开启异物检测板，异物检测板包括多个检测线圈。
在一实施例中，异物检测板的结构可如图6所示，包括横向(x轴方向)设置的n个检测线圈(X 1、X 2……X n)和纵向(y轴方向)设置的m个检测线圈(Y 1、Y 2……Y m)，其中n、m为正整数。
步骤205，按照预设时间间隔采集每个检测线圈的电压值。
步骤206，根据采集的每个检测线圈的电压值计算对应检测线圈在预设时间间隔内的电压变化率。
示例地，预设时间间隔用t 0表示，则横向第i个检测线圈在预设时间间隔内的电压变化率Δ Xi及纵向第k个检测线圈在预设时间间隔内的电压变化率Δ Yk的计算方法如下：
Figure PCTCN2022085689-appb-000001
其中，i∈[1，n]，k∈[1，m]，V Xi(t)表示以预设时间间隔采样得到横向第i个检测线圈的电压值，V Yk(t)表示以预设时间间隔采样得到纵向第k个检测线圈的电压值，t表示t时刻。
步骤207，根据每个检测线圈在预设时间间隔内的电压变化率计算变化率平均值，将变化率平均值作为电压变化值。
在一实施例中，可以按照如下公式计算电压变化值Δ V：
Figure PCTCN2022085689-appb-000002
步骤208，确定预设检测时长内得到的电压变化值是否超过预设阈值，若预设检测时长内得到的电压变化值超过预设阈值，则执行步骤209，若预设检测时长内得到的电压变化值未超过预设阈值，执行步骤210。
在一实施例中，预设检测时长大于预设时间间隔，即在预设检测时长内可以进行多次采样，因而在预设检测时长内可能得到多个电压变化值，只要其中的一个电压变化值超过预设阈值，即可认为预设检测时长内得到的电压变化值超过预设阈值。
在一实施例中，预设阈值可以用Δ 0表示，预设阈值可根据实际需求自定义取值，则可以判断Δ V与Δ 0的大小。
步骤209，确定检测到车辆，向车辆发送配对成功通知信息。
即如果Δ V超过Δ 0，则确定检测到车辆，如果Δ V不超过Δ 0，则确定未检测到车辆。
在一实施例中，如果检测到车辆，说明车辆当前所在充电车位与通信服务所选连接的电子设备所在的车位为同一车位，无线充电系统启动功率传输对当前车辆充电。
步骤210，确定未检测到车辆，向车辆发送配对失败通知信息。
在一实施例中，如果没有检测到车辆，说明车辆当前所在充电车位与通信服务所选连接的电子设备所在的车位不是同一车位，无线充电系统将不启动功率传输，此时，可以控制车辆退出当前充电车位，转而行驶至对应的充电车位。
本实施例中，在基于目标配对信息与车辆进行匹配后，会开启异物检测板，利用异物检测板对车辆进行检测，若检测到车辆，则向车辆发送配对成功通知信息，若未检测到车辆，则向车辆发送配对失败通知信息。即本实施例中，会利用异物检测板做配对的补充检测，以此提高配对准确率，避免无效配对；另外，由于异物检测板是电子设备的现有部件，因而本实施例并没有新增设备，不会增加系统成本和结构复杂度。
另外，在基于目标配对信息与车辆进行匹配时，在目标配对信息中引入功率等级、离地间隙以及工作频率等电气兼容参数，通过这些参数使得电子设备和车辆相互进行兼容性校验，从而保证了充电过程的电气安全。
