随着电力能源的飞速发展，新能源汽车以其使用成本低、环境污染小得到人们的青睐，而充电桩是新能源汽车提供动力续航的动力基地，一般安装于公共建筑、停车场或充电站内，可以根据不同的电压等级为各种型号的电动汽车充电。
充电桩通常是依靠充电枪对电动汽车进行充电，充电桩的还枪检测检测功能提高了充电桩的安全性和智能性，传统的还枪检测通常是依靠红外或超声波收发一体的模块完成，模块自动发出红外光，然后根据反射信号判断是否有充电枪插入枪位。然而，此种方案存在局限性，无法识别出是否是障碍物插入插槽，也难以识别其他充电枪插入非与之对应的插槽；因此，亟需一种更加精准的识别方案。

具体实施方式
为了便于理解本公开，下面结合附图和具体实施例，对本公开进行更详细的说明。需要说明的是，当元件被表述“固定于”另一个元件，它可以直接在另一个元件上、或者其间可以存在一个或多个居中的元件。当一个元件被表述“连接”另一个元件，它可以是直接连接到另一个元件、或者其间可以存在一个或多个居中的元件。
除非另有定义，本说明书所使用的所有的技术和科学术语与属于本公开的技术领域的技术人员通常理解的含义相同。本说明书中在本公开的说明书中所使用的术语只是为了描述具体的实施例的目的，不是用于限制本公开。
本公开的实施例提供了一种充电装置，请参照图1，该充电装置包括充电桩10和充电枪20。
充电桩10可与市电进行电连接，充电枪20则可通过线缆30与充电桩10电连接，充电桩10用于对充电枪20提供电力，充电枪20则可直接对电动汽车进行充电。
充电桩10上设有插槽11，通常情况下，充电桩10为竖直设置在地面上的箱体，插槽11的深度方向与充电桩10的竖直方向存在一定倾斜角，且插槽11的深度方向倾斜向下，或者，如图1所示，插槽11直接设置为水平状态。充电枪20可选择手持充电枪20，具体的，请参照图1，充电枪20包括枪头21、枪体22和把手23，枪体22的一端连接枪头21，另一端连接把手23，在充电枪20插接至插槽11内时，把手23显露于插槽11外，用户可直接通过把手23拿起充电枪20。为提高充电枪20的使用安全性，可在把手23上设置绝缘橡胶垫(绝缘橡胶垫未在图中示出)，绝缘橡胶垫上也可设置防滑纹路，以 便于用户手持充电枪20。充电枪20在不使用时，枪头21直接插接于充电桩10的插槽11内，以对充电枪20进行保护；充电枪20在使用时，枪头21可直接插接于外部电动汽车的充电槽，以对电动汽车进行充电。
为提高充电效率，减少成本，通常情况下，请参照图1，充电桩10会设置多个插槽11，相应的，每个插槽11均会各自对应设置一个充电枪20，充电枪20在对电动汽车充电完毕后，需要对充电枪20进行还枪归位，以将充电枪20完整的插接于充电桩10的插槽11；这就需要对充电枪20进行还枪检测，以保证充电枪20正确的插接于插槽11。
在一个实施例中，充电枪20的枪头21上设有电子标签24，而插槽11内设有阅读器12，阅读器12用于识别枪头21上的电子标签24，阅读器12包括预设信息，阅读识别电子标签24的信息后，可将电子标签24的信息与预设信息进行对比，以判断电子标签24的信息和预设信息是否相匹配。
具体的，请参照图2，充电装置包括三个充电枪G1、G2和G3，以及三个插槽g1、g2和g3，充电枪G1对应插槽g1，充电枪G2对应插槽g2，充电枪G3对应插槽g3；当充电装置同时对两辆车进行充电时，用户用充电枪G1充电完毕后，将充电枪G1插入了插槽g2内，插槽g2内的阅读器识别出电子标签的信息和该阅读器的预设信息不匹配，于是充电装置就会发出“未对应还枪”的警告。同样，当障碍物插接于插槽11内时，阅读器12无法识别障碍物，同样也会发出“未对应还枪”的警告，以让用户排查插槽11是不是被堵住。请参照图3，图3为枪头21完全插接于插槽11时的示意图。
在一个实施例中，也可在插槽11内设置检测装置(检测装置未在图中示出)，用于检测插槽11是否被障碍物堵住，例如，设置红外发射器和红外接收器，当障碍物堵住插槽11时，则挡住了红外发射器发出的红外线，使得红外接收器无法识别，并且，阅读器12也识别不到对应的电子标签24，这时，充电装置就会发出“障碍物堵住插槽11”的警告。
当用户将枪头21插入插槽11后，由于用户没有插接到位(没有完全插接到插槽11内)，导致阅读器12没有识别到枪头21上的电子标签24，这时充电装置还是显示“未还枪”，充电装置无法判断充电枪20是“还枪不到位”还是“未还枪”状态。
因此，在一个实施例中，充电枪20上设有至少两个电子标签24，在枪头21刚插接于插槽11时，阅读器12刚好识别于一个电子标签24，并将该电子标签24的信息与预设信息进行对比，当两个信息相匹配时，充电装置则显示“还枪不到位”，当枪头21完全插接于插槽11的状态下，阅读器12则刚好识别于另一个电子标签24，并将该电子标签24的信息与预设信息进行对比，当两个信息相匹配时，则充电装置显示“已还枪”。
具体的，请参照图4，为便于理解，电子标签24包括第一标签241和第二标签242，第一标签241包括信息A，第二标签242包括信息B，用户将枪头21插入插槽11后，由于没有插到位，导致充电装置只识别到信息A，没有 识别到信息B，此时，充电装置则发出“还枪不到位”的警告，以提示用户对充电枪20进行调整；当充电枪20插接到位时，阅读器12刚好识别第二标签242上的信息B，此时充电装置则发出“已还枪”的提示。同样的，当充电装置同时对两辆车进行充电时，用户用充电枪20G1充电完毕后，将充电枪20G1的插头插入了插槽11g2内，插槽11g2内的阅读器12检测出电子标签24的信息和阅读器12的预设信息不匹配，充电装置则发出“未对应还枪”的警告。
需要说明的是，为便于阅读器12精准检测第一标签241和第二标签242，且在第一时间使得阅读器12能够识别到第一标签241和第二标签242，第一标签241和第二标签242可分别设于枪头21的两端，阅读器12则可设置在插槽11的入口处，枪头21进入入口时，阅读器12刚好识别于第一标签241，在枪头21完全插接于插槽11的状态下，阅读器12刚好识别于第二标签242，这样充电装置就能够辨别出“未还枪”和“还枪不到位”两种状态。
在一个实施例中，枪头21的长度与插槽11的深度相适配，当枪头21完全插接于插槽11时，则充电枪20的枪体22和把手23均显露于插槽11外，通常情况下，枪头21是沿一个方向插接于插槽11内，为便于阅读器12识别上述两个上述电子标签24，可将第一标签241和第二标签242沿枪头21的长度方向排列设置，用户沿插槽11深度方向将枪头21插接于插槽11时，阅读器12可首先识别第一标签241，然后再识别第二标签242。可以理解的是，也可在枪头21上设置凹槽，凹槽沿枪头21的长度方向设置，插槽11内这设置与该凹槽相应的凸起，枪头21插接于插槽11时，凸起延伸于凹槽，以对枪头21进行限位，防止枪头21在插槽11内发生转动。
在一个实施例中，为便于枪头21找到插槽11的入口，请参照图5，插槽11还包括定位口111，定位口111的内壁与插槽11入口的内壁平滑连接，沿插槽11的深度方向，定位口111的横截面逐渐减小，可以理解的是，定位口111的开口大于插槽11的入口，定位口111可设置为锥状，其外部的开口横截面最大，以便于枪头21定位找到插槽11的入口。
在一个实施例中，为使得阅读器12精准识别于阅读器12，保证充电枪20准确的还枪到位，请参照图6，阅读器12可设置为多个，多个阅读器12与电子标签24一一对应，在枪头21完全插接于插槽11的状态下，每个阅读器12均刚好识别一个与之对应的电子标签24。多个阅读器12同时识别，以提高还枪检测的准确性。
在一个实施例中，为便于对用户进行“还枪到位”、“未对应还枪”等提示，充电枪20还包括第一指示灯和第二指示灯，第一指示灯均可设置在枪体22上(指示灯均为在图中示出)，即在充电枪20插接于所述插接的状态下，第一指示灯和第二指示灯均显露于插槽11外；第一指示灯用于显示充电枪20插接于与之对应的插槽11；第二指示灯用于显示充电枪20完全插接于与之对应的插槽11。
具体的，当阅读器12识别到第一标签241的信息A后，信息A与阅读器 12的第一预设信息匹配，此时第一指示灯亮起；当阅读器12识别到第二标签242的信息B后，信息B与阅读器12的第二预设信息匹配，此时第二指示灯亮起。同样，也可在充电枪20上设置第三指示灯，第三指示灯用于显示充电枪20处于充电状态。可以理解的是，上述指示灯也可换为显示屏，显示屏用于显示此时的还枪状态，也可换位语音播报器，通过语音播报器直接播报相应的还枪状态。
需要说明的是上述电子标签24可选择射频电子标签24，上述阅读器12可选择射频阅读器12，即RFID阅读器12。利用RFID近距离识别的特征，使得本实施例的充电装置可精确识别还枪状态。
本公开实施例的充电装置，充电枪20的枪头21上设有至少两个电子标签24，在枪头21刚插接于插槽11的状态下，阅读器12刚好识别于一个电子标签24，在枪头21完全插接于插槽11的状态下，阅读器12刚好识别于另一个电子标签24，使得充电装置可辨别出充电枪20是否对应还枪以及充电枪20是否还枪到位，可精确识别用户没有还枪和还枪不到位的状态差异，以防止用户错误还枪，提高充电装置还枪检测的准确性。
需要说明的是，本公开的说明书及其附图中给出了本公开的较佳的实施例，但是，本公开可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本公开内容的额外限制，提供这些实施例的目的是使对本公开的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本公开说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本公开所附权利要求的保护范围。
