控制器35根据开锁命令，控制电机331进入开锁工作状态，电机331驱动传动机构332带动锁止件333朝着背离充电枪200的插孔的方向进行移动，直至锁止件333移出插孔，从而完成开锁操作。
在一些实施例中，请参阅图5，电子锁33还包括行程开关334，行程开关334设置于电子锁33内且与控制器35电连接，用于产生位置信号以检测锁止件333的位置。
在一些实施例中，行程开关334的数量为至少两个，第一行程开关设置在电子锁的伸舌起始位置，第二行程开关设置在电子锁的伸舌终点位置，其中，伸舌起始位置被定义为锁止件333开始执行关锁操作的起始点，伸舌终点位置被定义为锁止件333开始执行开锁操作的起始点。
电机331进入关锁工作状态时，能够驱动传动机构带动锁止件333自伸舌起始位置开始移动，当锁止件333的位置抵达伸舌终点位置时，所述第二行程开关产生高电平的位置信号，所述高电平的位置信号用于表示锁止件333移动至充电枪200的插孔内了，亦即执行关锁操作完毕。
电机331进入关锁工作状态时，若控制器35未检测到第二行程开关的高电平，则控制器35确定关锁操作尚未完成。
电机331进入开锁工作状态时，能够驱动传动机构带动锁止件333自伸舌终点位置开始移动，当锁止件333的位置抵达伸舌起始位置时，所述第一行程开关产生高电平的位置信号，所述高电平的位置 信号用于锁止件333移动至充电枪200的插孔内了，亦即执行关锁操作完毕。
电机331进入开锁工作状态时，若控制器35未检测到第一行程开关的高电平，则控制器35确定开锁操作尚未完成。
通信模组34与控制器35连接，用于与外部设备进行通信，其中，外部设备可以为服务器和/或移动终端。请参阅图6，外部设备分别为服务器500和移动终端600。
服务器500通过通信模组34与充电桩300进行通信，比如，服务器500可以向充电桩300发送充电配置信息，充电配置信息用于配置充电桩300的相应工作参数，比如，充电桩300根据充电配置信息，更新功率监控阈值，功率监控阈值用于充电桩300监控输出功率是否过大，以确保充电桩300进行充电时的安全性。再比如，充电桩300可以向服务器500发送工作参数信息，服务器500解析工作参数信息，根据解析结果，判断充电桩300的工作情况，以便有效地维护好充电桩300。
在一些实施例中，服务器500可以是一个物理服务器或者多个物理服务器虚拟而成的一个逻辑服务器。服务器500也可以是多个可互联通信的服务器组成的服务器群，且各个功能模块可分别分布在服务器群中的各个服务器上。
移动终端600能够与服务器500进行通信，并通过服务器500，向充电桩300下发控制命令。
在一些实施例中，移动终端600支持各种桌面应用程序的安装，诸如：充电服务应用程序、照片应用程序或录像应用程序等。
用户可将充电服务应用程序安装在移动终端600中，通过充电服务应用程序向服务器500发送注册信息，其中，注册信息包括需注册的用户信息及密码，服务器500根据注册信息，为所述用户分配经过授权认证的账号。
当用户完成注册后，用户可以操作移动终端600启动充电服务应用程序，充电服务应用程序的登录界面包括账号输入区、密码输入区及登录按键，其中，账号输入区用于输入经过合法认证的账号，密码输入区用于输入与账号对应的密码，登录按键用于响应用户的登录按键操作，向服务器500发送登录请求，其中，登录请求携带账号与密码。服务器500根据登录请求，认证账号和密码是否合法，若是，则控制移动终端600登录充电服务应用程序，若否，则拒绝移动终端600登录充电服务应用程序。
当移动终端600登录充电服务应用程序后，用户可在充电服务应用程序建立充电枪档案库，其中，充电枪档案库包括充电枪的设备信息及在设备信息下的充电信息，充电枪的设备信息为充电枪的设备系列号。
充电信息包括充电枪在充电桩进行充电时的充电位置、充电桩标识、充电时间、充电时长及开关时间，充电位置为充电桩的地理位置，充电桩标识为用于标记充电桩的标识，充电时间包括充电起始时间和充电结束时间，充电起始时间为用户的电动车辆在充电桩上开始充电的时间，充电结束时间为用户的电动车辆在充电桩上结束充电的时间，充电时长为用户的电动车辆在充电桩上进行充电的时长，开关时间为充电桩对充电枪进行开锁或关锁的时间，亦即，开关时间可为开锁时间，也可为关锁时间，或者为同一次充电过程的开锁时间与关锁时间的总和。
本实施例提供表1，用于阐述充电枪档案库，如表1所示：
表1
由表1可知，充电枪Q1可以插接在不同充电桩进行充电，服务器500和移动终端600可以记录充电枪Q1下的开关时间，比如，充电枪Q1的开关时间集合＝{(1.0,0.9),(1.0,1.0),(0.9,0.9),(0.9,1.0)}。
可以理解的是，由于充电桩和充电枪是分开的，如表1所示，同一个充电枪可插接在不同充电桩 进行充电。同理可得，同一个充电桩可为不同充电枪提供电源，请参阅表2：
表2
由表2所示，充电桩Z1能够为不同用户的充电枪提供电源，服务器500和充电桩Z1可以记录充电桩Z1下的开关时间，比如，充电桩Z1的开关时间集合＝{(1.0,0.9),(0.8,1.0),(1.0,0.9),(1.0,0.9)}。
本实施例提供一种充电应用场景，以便详细阐述充电桩Z1、充电枪Q1、服务器500及移动终端600的充电过程，具体如下：
用户驾驶电动车辆400到充电桩Z1附近，从电动车辆400内取出充电枪Q1，将充电枪Q1的桩体插头通过机械锁头卡扣在充电桩Z1的插座上，将充电枪Q1的车辆插头插接在电动车辆400的车辆充电插口上。
充电桩Z1的显示屏呈现二维码。用户操作移动终端600登录充电服务应用程序，单击充电服务应用程序的扫描按键，以扫描二维码，于是，移动终端600根据二维码的内容，向服务器500发送充电准备请求，其中，充电准备请求携带充电桩Z1的设备信息和充电枪Q1的设备信息。
服务器500根据充电准备请求，判断充电桩Z1是否可提供电能，若充电桩Z1可提供电能，则向充电桩Z1发送关锁命令，充电桩Z1根据关锁命令，控制电子锁执行关锁操作和记录关锁时间，亦即控制电机带动锁止件朝向靠近充电枪Q1的插孔的方向进行移动，以将锁止件插接在插孔内，从而固定充电枪Q1。
若充电桩Z1不可提供电能，则向充电桩Z1发送不可充电信息，充电桩Z1在显示屏上呈现不可充电信息，以便用户更换充电桩进行充电。
当充电桩Z1固定好充电枪Q1后，用户单击充电服务应用程序的充电UI界面的开始充电按键，开始充电按键用于响应用户的开始充电操作，促使移动终端600向服务器500发送开始充电请求。服务器500根据开始充电请求，控制充电桩Z1为充电枪Q1提供电能，并且开始计时。
充电结束后，用户单击充电服务应用程序的充电UI界面的结束充电按键，结束充电按键用于响应用户的结束充电操作，促使移动终端600向服务器500发送结束充电请求。服务器500根据结束充电请求，控制充电桩Z1停止为充电枪Q1提供电能，结束计时，并且向充电桩Z1发送开锁命令。充电桩Z1根据开锁命令，控制电子锁执行开锁操作和记录开锁时间，亦即控制电机带动锁止件朝向背离充电枪Q1的插孔的方向进行移动，以将锁止件移出插孔，从而将充电枪Q1从充电桩Z1中进行释放。
控制器35作为充电桩300的控制核心，其中，控制器35可以为通用处理器、数字信号处理器、专用集成电路、现场可编程门阵列、单片机、ARM或其它可编程逻辑器件、分立门或晶体管逻辑、分立的硬件组件或者这些部件的任何组合。还有，控制器35还可以是任何传统处理器、控制器、微控制器或状态机。控制器35也可以被实现为计算设备的组合，例如，DSP和微处理器的组合、多个微处理器、一个或多个微处理器结合DSP核、或任何其它这种配置。
作为本申请实施例另一方面，本申请实施例提供一种插座型充电桩的电子锁卡锁预判方法，可以理解的是，插座型充电桩的电子锁卡锁预判方法的执行主体可以为充电桩，亦可以为其它具有逻辑运算功能和分析功能的设备，比如，所述设备为服务器等。请参阅图7，插座型充电桩的电子锁卡锁预判方法包括：
S71.获取时间分布数据。
在本步骤中，时间分布数据包括电子锁对每个充电枪执行开关操作的多个开关时间，如前所述，开关时间为充电桩对充电枪进行开锁或关锁的时间，亦即，开关时间可为关锁时间，也可为开锁时间， 或者为同一次充电过程的开锁时间与关锁时间的总和。举例而言，请结合表2，当开关时间为关锁时间时，时间分布数据T＝{1.0,0.8,1.0,1.0}。当开关时间为开锁时间时，时间分布数据T＝{0.9,1.0,0.9,0.9}。当开关时间为同一次充电过程的开锁时间与关锁时间的总和时，时间分布数据T＝{1.9,1.8,1.9,1.9}。
在一些实施例中，充电桩向服务器发送时间获取请求，其中，时间获取请求携带充电桩的设备信息。服务器根据时间获取请求，搜索与所述设备信息对应的充电桩，并向所述充电桩发送时间分布数据，充电桩接收时间分布数据。
S72.根据时间分布数据，生成多个开关时间对应的卡锁特征。
在本步骤中，卡锁特征为用于表示所述电子锁是否处于卡锁临界状态的特征。本实施例根据时间分布数据的多个开关时间，结合卡锁特征提取规则，生成卡锁特征，其中，卡锁特征提取规则可以为相似度算法或者统计学的数据处理算法等。
在一些实施例中，本实施例根据时间分布数据的多个开关时间，计算第一时间平均值，将第一时间平均值作为卡锁特征，比如，请结合表2，当开关时间为关锁时间时，时间分布数据T＝{1.0,0.8,1.0,1.0}，则第一时间平均值为0.95秒，卡锁特征为0.95秒。
在一些实施例中，本实施例根据时间分布数据的多个开关时间，筛选出时间连续且时长大于或等于指定阈值的开关时间的数量，将数量作为开关卡锁特征，比如，请结合表2，当开关时间为关锁时间时，时间分布数据T＝{1.0,0.8,1.0,1.0}，指定阈值为0.9，由于0.8秒之后的两个1.0秒的时间连续，并且都大于0.9，因此，数量为2，卡锁特征为2。
可以理解的是，由于卡锁特征提取规则的不同，提取出的卡锁特征类型可以不同，比如，卡锁特征可以为时间分布数据的时间平均值，亦可以为时间分布数据中超过相应预设阈值的开关时间的数量，也可以为时间分布数据的波动率。
S73.根据卡锁特征，预判电子锁是否处于卡锁临界状态。
在本步骤中，卡锁临界状态为电子锁进入卡锁状态前的临界状态，卡锁状态为电子锁的锁止件被卡住的状态。
在一些实施例中，本实施例判断卡锁特征是否大于或等于预设特征，若卡锁特征大于或等于预设特征，则预判电子锁处于卡锁临界状态，若卡锁特征小于预设特征，则预判电子锁处于正常状态。
在一些实施例中，当第一时间平均值为卡锁特征时，本实施例判断第一时间平均值是否大于或等于指定时间阈值，若第一时间平均值大于或等于指定时间阈值，则预判电子锁处于卡锁临界状态，若第一时间平均值小于指定时间阈值，则预判电子锁处于正常状态。
在一些实施例中，当数量为卡锁特征时，本实施例判断数量是否大于或等于指定数量阈值，若数量大于或等于指定数量阈值，则预判电子锁处于卡锁临界状态，若数量小于指定数量阈值，则预判电子锁处于正常状态。
如前所述，由于本实施例提供的充电桩设有插座，电子锁安装于插座上，用于对插接在插座的充电枪进行关锁或开锁，因此，本实施例提供的充电枪和充电桩是分开的，用户需要充电时再将充电枪插入充电桩中，有利于更好地维护好充电枪。另外，本实施例能够自动预判电子锁是否处于卡锁临界状态，以便充电桩的管理者采取相应保养维护工作，有利于提高用户体验感。
对于用户，充电桩与充电枪是分开的，用户需要为电动车辆进行充电时，再将充电枪的桩体插头插接到充电桩的插座上，车辆插头插接到电动车辆的车辆充电插口上。
对于同一个充电桩，不同充电枪可分时插接在同一个充电桩进行充电。当出现卡锁现象时，有的用户的充电枪维护比较好，此时的卡锁现象也许是充电桩带来的。有的用户的充电枪维护比较差或者使用年限比较久或者受腐蚀而生锈或者材料变形而使得摩擦力比较大，此时的卡锁现象也许是充电枪带来的，此类充电枪的开关时间通常是比较大的，有时会比较正常开关时间高出1倍以上，如此，此类充电枪的开关时间会拉高时间分布数据的整体水平，会引起误判充电桩的电子锁即将进入卡锁临界状态，实际上充电桩的电子锁是正常的。
基于此，在一些实施例中，本实施例根据时间分布数据生成多个开关时间对应的卡锁特征，请参阅图8，S72包括：
S721.根据时间分布数据，确定开关时间的效力属性。
S722.根据开关时间的效力属性，提取出有效属性的开关时间。
S723.根据有效属性的开关时间，生成卡锁特征。
在S721中，效力属性为开关时间是否有效的属性，其中，效力属性包括有效属性和无效属性，有效属性指开关时间为有效的属性，无效属性指开关时间为无效的属性。
若受充电枪因素的影响而使得开关时间出现异常时，则充电桩记录所述充电枪的开关时间为无效的。若受充电桩的电子锁因素的影响而使得开关时间出现异常时，则充电桩记录所述充电枪的开关时间为有效的。因此，为了区分出时间分布数据内的各个开关时间的效力属性，以便能够更加有效的预判充电桩的电子锁是否处于卡锁临界状态，本实施例需要根据时间分布数据，确定开关时间的效力属性。
举例而言，当开关时间为关锁时间时，充电桩的时间分布数据Tp包括10个用户的充电枪在同一个充电桩进行充电时的关锁时间，如表3所示：
表3
如表3所示，充电枪5的关锁时间Tp5＝2.2秒，充电枪9的关锁时间Tp9＝3.2秒，充电枪5和充电枪9的关锁时间相对其它用户的关锁时间差异比较大，本实施例可以结合筛选规则，将充电枪5的关锁时间Tp5的效力属性设置为无效属性，将充电枪9的关锁时间Tp9的效力属性设置为无效属性，以及将剩余用户的关锁时间的效力属性设置为有效属性，因此，执行完S721后，每个用户的关锁时间的效力属性如表4所示：
表4
在S722中，在一些实施例中，本实施例将每个开关时间的效力属性与属性标签进行比对，若效力属性匹属性标签，则将所述开关时间记录在第一队列，若效力属性不匹配有效性标签，则将所述开关时间记录在第二队列，其中，所述属性标签可为有效属性标枪，也可为无效属性标签。请结合上述例子，执行完S722后，第一队列L1＝{Tp1,Tp2,Tp3,Tp4,Tp6,Tp7,Tp8,Tp10}，第二队列L2＝{Tp5,Tp9}。
在S723中，在一些实施例中，由于第一队列记录的开关时间的效力属性都是有效属性，因此，本实施例可以根据第一队列的开关时间，生成卡锁特征。另外，由于作为有效属性的开关时间已排除了受到不良充电枪的影响，因此，生成的卡锁特征能够可靠有效地反映出电子锁是否处于卡锁临界状态。
可以理解的是，除了充电枪的因素会影响到开关时间的效力属性之外，也会存在其它因素影响到开关时间的效力属性，比如充电桩工作的环境因素或人为恶意操作充电桩的电子锁等，但是，本实施例提供的方法也可以适用于其它因素对开关时间的效力属性的影响，也能够准确可靠地生成卡锁特征。
在一些实施例中，效力属性包括有效属性和无效属性，请参阅图9，S721包括：
S7211.判断开关时间对应的目标充电枪是否满足枪体故障条件。
S7212.若满足，则确定开关时间的效力属性为无效属性。
S7213.若未满足，则确定开关时间的效力属性为有效属性。
在S7211中，目标充电枪为时间分布数据中每个开关时间对应的充电枪，如表3所示，关锁时间T1对应用户1的充电枪，执行S7211时，用户1的充电枪可为目标充电枪。接着，关锁时间T2对应用户2的充电枪，执行S7211时，用户2的充电枪可为目标充电枪，以此类推。
枪体故障条件为用于判断目标充电枪执行开关操作时是否存在异常情况的条件，设计者可以根据工程经验，自行构建枪体故障条件。
在S7212中，由于开关时间对应的目标充电枪满足枪体故障条件，因此，所述开关时间的效力属性为无效属性，其不参与卡锁特征的生成，以避免影响预判电子锁是否处于卡锁临界状态的判断结果。
在S7213中，由于开关时间对应的目标充电枪不满足枪体故障条件，因此，所述目标充电枪执行开关操作时是良好的，所述开关时间的效力属性为有效属性，其能够参与卡锁特征的生成，以便能够准确可靠地预判电子锁是否处于卡锁临界状态。
在一些实施例中，本实施例判断开关时间对应的目标充电枪是否满足枪体故障条件时，请参阅图10，S7211包括：
S74.获取开关时间对应的目标充电枪的充电信息，其中，充电信息包括目标充电枪在不同充电桩 进行充电的多个历史开关时间。
S75.根据历史开关时间，判断目标充电枪是否满足枪体故障条件。
在S74中，历史开关时间为相对当前充电桩而言，目标充电枪在其它充电桩进行充电时的开关时间。举例而言，对于充电枪Q1，当开关时间为关锁时间时，可由表1提供的数据归纳得到表5，请参阅表5：
表5
由表5可知，充电枪Q1分别在充电桩1、充电桩2、充电桩3及充电桩4上使用过，其中，开关时间Tq1、开关时间Tq2、开关时间Tq3及开关时间Tq4都为历史开关时间，因此，充电枪Q1的充电信息Tq＝{Tq1,Tq2,Tq3,Tq4}。
在S75中，本实施例可以基于充电信息的历史开关时间，结合相应规则，判断目标充电枪是否满足枪体故障条件。
在一些实施例中，请参阅图11，S75包括：
S751.求取多个历史开关时间的历史时间平均值。
S752.判断历史时间平均值是否大于或等于第一预设时间阈值。
S753.若是，则确定目标充电枪满足枪体故障条件。
S754.若否，则确定目标充电枪不满足枪体故障条件。
在S751中，在一些实施例中，本实施例将多个历史开关时间进行相加，得到历史时间总和，将历史时间总和除以历史开关时间的数量，得到历史时间平均值。举例而言，假设充电枪Q1的充电信息Tq＝{Tq1,Tq2,Tq3,Tq4,Tq5,Tq6,Tq7,Tq8,Tq9,Tq10}，其中，Tq'为历史时间平均值。
与上述实施例不同点在于，在一些实施例中，本实施例将多个历史开关时间中的最大历史开关时间和最小历史开关时间进行剔除，再对剩余历史开关时间进行相加，得到历史时间总和，将历史时间总和除以剩余历史开关时间的数量，得到历史时间平均值。举例而言，比如Tq3是最小历史开关时间，Tq8是最大历史开关时间，本实施例剔除最小历史开关时间Tq3和最大历史开关时间Tq8，再计算剩余历史开关时间的历史时间平均值。
在S752中，第一预设时间阈值可由设计者根据工程经验自定义，比如，第一预设时间阈值为1.5秒或2秒或2.5秒或3秒等。
在S753中，由于历史时间平均值大于或等于第一预设时间阈值，说明目标充电枪执行开关操作时出现了异常，因此，本实施例可确定目标充电枪满足枪体故障条件，目标充电枪在充电桩进行充电时的开关时间的效力属性为无效属性，因此，本实施例需要将目标充电枪的开关时间从时间分布数据中进行剔除。
在S754中，由于历史时间平均值小于第一预设时间阈值，说明目标充电枪执行开关操作时被视为正常，因此，本实施例可确定目标充电枪不满足枪体故障条件，目标充电枪在充电桩进行充电时的开关时间的效力属性为有效属性，因此，本实施例将目标充电枪的开关时间保留在时间分布数据中。
在一些实施例中，本实施例根据有效属性的开关时间生成卡锁特征时，请参阅图12，S723包括：
S7231.根据有效属性的开关时间，计算开关时间平均值。
S7233.将开关时间平均值作为卡锁特征。
在S7231中，在一些实施例中，本实施例将多个有效属性的开关时间进行相加，得到开关时间总和，将开关时间总和除以有效属性的开关时间的数量，得到开关时间平均值。举例而言，时间分布数据Ts＝{Ts1,Ts2,Ts3,Ts4,Ts5,Ts6,Ts7,Ts8,Ts9,Ts10}，由于开关时间Ts4和开关时间Ts7的效力属性为无效属性，因此本实施例将开关时间Ts4和开关时间Ts7从时间分布数据中进行剔除，剩余的时间分布数据Ts＝{Ts1,Ts2,Ts3,Ts5,Ts6,Ts8,Ts9,Ts10}，因此，有效属性的开关时间的数量为8，开关时间总和T总＝Ts1+Ts2+Ts3+Ts5+Ts6+Ts8+Ts9+Ts10，开关时间平均值＝T总/8。
在S7233中，如前所述，开关时间平均值T总/8为卡锁特征。
与上述实施例不同点在于，在一些实施例中，本实施例将多个有效属性的开关时间中的最大开关时间和最小开关时间进行剔除，再对剩余开关时间进行相加，得到开关时间总和，将开关时间总和除以有效属性的开关时间的数量，得到开关时间平均值。
在一些实施例中，本实施例根据卡锁特征预判电子锁是否处于卡锁临界状态时，请参阅图13，S73包括：
S731.判断开关时间平均值是否大于或等于第二预设时间阈值。
S733.若开关时间平均值大于或等于第二预设时间阈值，则预判电子锁处于卡锁临界状态。
S735.若开关时间平均值小于第二预设时间阈值，则预判电子锁处于正常状态。
在S731中，第二预设时间阈值可由设计者根据工程经验自定义，比如，第二预设时间阈值为1.5秒或2秒或2.5秒或3秒等。
在S733中，由于开关时间平均值大于或等于第二预设时间阈值，说明充电桩的电子锁出现异常，容易出现卡锁现象，因此，本实施例可以预判电子锁处于卡锁临界状态。
在一些实施例中，若开关时间平均值大于最大预设时间阈值，说明充电桩的电子锁已经处于卡锁状态。
在S735中，由于开关时间平均值小于第二预设时间阈值，说明充电桩的电子锁是正常工作的，因此，本实施例可以预判电子锁处于正常状态。
本实施例通过求取开关平均时间值，并将开关平均时间值作为卡锁特征，根据卡锁特征预判电子锁是否处于卡锁临界状态，此种方式利用较多开关时间参与计算，能够准确可靠地反映出电子锁是否处于卡锁临界状态。
与上述实施例不同点在于，在一些实施例中，在一些实施例中，本实施例根据有效属性的开关时间生成卡锁特征时，请参阅图14，S723包括：
S7232.根据有效属性的开关时间，筛选出时间连续且开关时间大于或等于第三预设时间阈值的数量。
S7234.将数量作为开关卡锁特征。
在S7232中，举例而言，时间分布数据Ts＝{Ts1,Ts2,Ts3,Ts4,Ts5,Ts6,Ts7,Ts8,Ts9,Ts10}，由于开关时间Ts4和开关时间Ts7的效力属性为无效属性，因此本实施例将开关时间Ts4和开关时间Ts7从时间分布数据中进行剔除，剩余的时间分布数据Ts＝{Ts1,Ts2,Ts3,Ts5,Ts6,Ts8,Ts9,Ts10}。
在剩余的时间分布数据Ts＝{Ts1,Ts2,Ts3,Ts5,Ts6,Ts8,Ts9,Ts10}中，由于开关时间Ts1、开关时间Ts8、Ts9及Ts10都小于第三预设时间阈值，开关时间Ts2、Ts3、Ts5、Ts6都大于第三预设时间阈值，因此，数量为4。
在S7234中，数量4为卡锁特征。
在一些实施例中，本实施例根据卡锁特征预判电子锁是否处于卡锁临界状态时，请参阅图15，S73包括：
S732.判断数量是否大于或等于预设数量阈值。
S734.若数量大于或等于预设数量阈值，则预判电子锁处于卡锁临界状态。
S736.若数量小于预设数量阈值，则预判电子锁处于正常状态。
在S732中，预设数量阈值可由设计者根据工程经验自定义，比如，预设数量阈值为3或4或5等。
在S734中，由于数量大于或等于预设数量阈值，说明充电桩的电子锁出现异常，容易出现卡锁现象，因此，本实施例可以预判电子锁处于卡锁临界状态。
在一些实施例中，若数量大于最大预设数量阈值，说明充电桩的电子锁已经处于卡锁状态，比如最大预设数量阈值为8或10。
在S736中，由于数量小于预设数量阈值，说明充电桩的电子锁是正常工作的，因此，本实施例可以预判电子锁处于正常状态。
本实施例通过求取数量，并将数量作为卡锁特征，根据卡锁特征预判电子锁是否处于卡锁临界状态，此种方式利用较少开关时间便可快速地预判电子锁是否处于卡锁临界状态，能够满足一些对卡锁预判实时性有要求的场景。
为了详细阐述本实施例，本实施例提供两种应用场景对此进行说明，具体如下所述：
第一应用场景：
本应用场景结合表6和表7对此作出详细的阐述，其中，表6所展示的数据为10个用户在充电桩Z1下进行充电的数据，表7所展示的数据为表6所示的10个用户的充电枪在不同充电桩进行充电的数 据，请参阅表6和表7：
表6
表7
如表6所示，充电枪1至充电枪10都在充电桩Z1进行充电时，得到的时间分布数据如表6所示，时间分布数据Tr＝{1.0,0.8,1.0,1.0,2.2,1.0,0.9,0.9,3.2,1.0}。
如表7所示，充电枪1在10个充电桩进行充电时的开关时间分别为{1.0,0.9,1.0,0.9,1.1,1.0,1.0,1.2,1.0,1.0}，同理可得其它充电枪在10个充电桩进行充电时的开关时间。
假设第一预设时间阈值为2，由于充电枪1、充电枪2、充电枪3、充电枪4、充电枪6、充电枪7、充电枪8及充电枪10的开关平均时间都小于2，但是充电枪5及充电枪9的开关平均时间都大于2，因此，充电枪5及充电枪9的开关时间的效力属性都为无效属性，本实施例需要在时间分布数据Tr中剔除充电枪5的开关时间Tr5和充电枪9的开关时间Tr9，时间分布数据Tr中剩余开关时间{1.0,0.8,1.0,1.0,1.0,0.9,0.9,1.0}的效力属性为有效属性。
本实施例根据有效属性的开关时间，计算开关时间平均值，因此可得到开关时间平均值为0.95，因此，卡锁特征为0.95。假设第二预设时间阈值为1.5，由于0.95小于1.5，因此，本实施例预判电子锁处于正常状态。
第二应用场景：
本应用场景结合表8和表9对此作出详细阐述，其中，表8所展示的数据为10个用户在充电桩Z1下进行充电的数据，表9所展示的数据为表8所示的10个用户的充电枪在不同充电桩进行充电的数据，请参阅表8和表9：
表8
表9
如表8所示，充电枪1至充电枪10都在充电桩Z1进行充电时，得到的时间分布数据如表8所示，时间分布数据Tx＝{2.2,2.4,2.5,2.2,4.2,2.2,2.1,2.3,5.4,2.4}。
如表9所示，充电枪1在10个充电桩进行充电时的开关时间分别为{2.2,0.9,1.0,0.9,1.1,1.0,1.0,1.2,1.0,1.0}，同理可得其它充电枪在10个充电桩进行充电时的开关时间。
假设第一预设时间阈值为2，由于充电枪1、充电枪2、充电枪3、充电枪4、充电枪6、充电枪7、充电枪8及充电枪10的开关平均时间都小于2，但是充电枪5及充电枪9的开关平均时间都大于2，因此，充电枪5及充电枪9的开关时间的效力属性都为无效属性，本实施例需要在时间分布数据Tx中剔除充电枪5的开关时间Tx5和充电枪9的开关时间Tx9，时间分布数据Tx中剩余开关时间{2.2,2.4,2.5,2.2,2.2,2.1,2.3,2.4}的效力属性为有效属性。
本实施例根据有效属性的开关时间，计算开关时间平均值，因此可得到开关时间平均值为2.2875，因此，卡锁特征为0.95。假设第二预设时间阈值为1.5，由于2.2875大于1.5，因此，本实施例预判电子锁处于卡锁临界状态。
总体而言，本实施例能够自动预判电子锁是否处于卡锁临界状态，以便充电桩的管理者采取相应保养维护工作，有利于提高用户体验感。
