如图1所示，本发明一实施方式的电动车的充电系统包括：
充电电源100，用于向电动车500提供电能并用于从电动车获取电动车的电瓶标识；
网关200，与充电电源100通过电力线600连接并且通过充电电源100从电动车获取电动车的电瓶标识并发送给下述的后台服务器400；

其中，充电电源100包括：
电源模块110，用于向电动车500提供电能；以及

接着，对于利用上述电动车的充电系统实现的电动车的充电方法进行说明。
当电动车500通过插座300与充电电源100连接上以后，充电电源100作为信息发送方，在充电电源100中，第一耦合模块120的接口模块121通过串口或内部总线读取电动车500的电瓶标识(数字信号)，并通过第一耦合模块120 中的数模转换模块122、调制模块123电瓶标识进行调制处理和数模转换，将数字信号的电瓶标识转换为模拟信号，然后，通过载波模块124将高频模拟信号加载到电力线600(例如50HZ)上，也可以是将表示电瓶标识的模拟信号和待充电信息一起加载到电力线600上。

以上描述的过程是假设电动车的电瓶标识已与用户账户信息预先进行了绑定(即已进行了用户注册)，若两者之间还没有绑定的话，则在第一触发步骤S100之前进一步包括：

接着，对于使用本实施方式的电动车的充电方法实现充电过程中的几个场景进行说明。
1.电动车无感充电开通(未注册用户)
初始化：根据统一标准或规范，设备生产厂商为电瓶配置电瓶标识，并设置为能够通过接口读取该电瓶标识(其中，电瓶标识为不可更改)；
标识读取：用户将电动车与插座、充电电源连接好后，网关通过电信号检测电动车与网关的连接，连接成功后，网关通过电力线即利用PLC电力载波通信方式与电动车进行通信，读取电动车的电瓶标识；
用户扫码注册开通：网关读取电瓶标识后，由网关的展示模块生成二维码信息并使得展示在显示设备(该显示设备未图示)上，用户通过扫描二维码信息进行注册(例如，小程序、运营商APP、公众号等方式)，以将电瓶标识和用户账户信息(例如付款的银行卡账户、支付账户等)上传到后台服务器并进行两者的绑定，同时，进一步也提示用户授权无感充电开通。这里所谓的“无感充电”主要指用户插上充电电源(即电动车与插座、充电电源连接)之后自动开始充电，用户拔开充电电源(即电动车与插座、充电电源断开连接)之后自动完成支付。
2.电动车无感充电(已注册用户)：
初次充电：用户授权无感充电开通后，通过移动终端侧或网关的按钮(未图示)控制启动对电动车的充电，通过网关读取充电状态并与后台服务器的交互确认启动充电成功，后续，用户仍可通过移动终端侧或网关的按钮控制充电启动(也可以是连接插座后自动启动充电)。
预扣费：网关检测连接状态后，触发无感充电流程，网关发送充电信息给后台服务器(包含电动车的电瓶标识)。后台服务器通过电瓶标识得到与其绑定的用户账户信息，并检测是否已预扣费。若未扣费，则调用支付预授权接口进行后台预置费用的预扣费，若已扣费，则继续充电。
无感充电：在通过预授权接口扣费成功后，通过网关控制插座使得电动车继续充电，否则，中止充电。
充电完成：电动车的电瓶充满或用户主动断开插座的连接而中止充电后，网关检测充电状态后，将充电状态信息上送后台服务器，其中，作为充电状态信 息，例如可以列举包括但不限于：充电电量、充电电流、充电电压、充电时长、剩余充电时长、车辆VIN码、桩编码等。后台服务器收到充电状态信息后计算实际费用信息，通过电瓶标识查询绑定的用户账户信息，并调用支付预授权完成接口完成充电费用扣除和结算，完成充电。
3.电动车无感充电(未注册扫码充电用户)：
标识读取：用户将电动车与插座、充电电源连接好之后，网关通过电力线与电动车通信，读取电动车的电瓶标识，启动充电的同时将电瓶标识与用户账户信息发送到后台服务器以实现电瓶标识与用户账户信息的绑定。
用户开通无感充电：后台服务器向用户推送通知/提供授权开通入口，用户授权无感充电开通。
启动及预扣费：网关检测到充电电源、插座与电动车的连接状态后，触发无感充电流程，网关发送充电状态给后台服务器(包含电动车的电瓶标识)。后台服务器通过电瓶标识获得与其绑定的用户账户信息，并检测是否已预扣费。若未扣费，则调用支付预授权接口进行后台预置费用的预扣费，若已扣费，则继续充电。
无感充电：通过预授权接口扣费成功后，通过网关控制电瓶车继续充电，否则，中止充电。
充电完成：在电动车的电瓶充满或用户主动断开插座的连接而中止充电后，网关检测充电状态后，将充电状态信息上送后台服务器，后台服务器计算实际费用信息，通过电瓶标识查询用户账户信息，并调用支付预授权完成接口完成充电费用扣除和结算，完成充电。
接着，对于本发明的电动车的充电方法两个实施例进行说明。

实施例3(换电柜场景)
实施例3说明了一个换电柜场景下的充电系统。
图4是表示本发明实施例3的换电柜场景下的充电系统的结构示意图。
如图4所示，10表示充电电源，20表示网关，30表示充电柜，40表示后 台服务器，50表示电力线。其中，充电柜30和多个充电电源10分别电连接，充电柜30中例如可以划分为1-8号的8个充电柜(这里的柜子数量仅仅是用于举例说明，并没有限定作用)，在充电柜30中可以收纳需要进行充电的电瓶。
在实施例3中，对于电瓶进行充电方法主要包括下述步骤：
将电动车的电瓶放入到充电柜30，相当于通过充电柜30建立了充电电源10与电瓶的电连接关系；
网关20通过基于电力线40的载波通信方式与充电电源10、充电柜30进行通信获取电瓶的电瓶标识；
网关20读取电瓶标识后，生成二维码信息，并显示在网关20具备的显示屏上；用户通过运营商APP或者公众号码或者小程序扫描等方式扫描二维码信息进行注册并授权无感充电开通，具体地，例如用户通过手机等扫描二维码信息，获取电瓶标识并且同时将需要与该电瓶标识进行的绑定用户账户信息传送到后台服务器40，在后台服务器40中建立电瓶标识和用户账户信息的绑定关系，同时对该电瓶标识和用户账户信息开通授权无感充电；
通过手机侧或者网关的按钮控制启动对电瓶的充电；
充电启动后，网关20将电瓶标识发送到后台服务器40，后台服务器40基于该电瓶标识绑定的用户账户信息进行预扣费，扣费成功后继续充电(否则中止充电)；电瓶充满电或者用户手动中止充电后，网关20读取充电状态变化，网关20将相关于充电的启动和中止的充电状态信息和电瓶标识发送到后台服务器40，后台服务器40计算实际费用，并按照电瓶标识找到与该电瓶标识绑定的用户账户进行费用结算。
另外，作为实施例3的一个变形例，网关20也可以不单独设置而是作为充电柜30的一部分设置，例如在充电柜30上方增加一个用于实现网关20功能的组成部分。
本发明的电动车的充电系统以及电动车的充电方法中，通过对网关、电动车的充电电源进行改造，能够通过基于电力线的PLC电力载波通信方式实现网关与电动车的通信，由此读取电动车的电瓶标识。并且，通过将电瓶标识与用户账户信息在后台服务器进行绑定(注册用户)，基于与电瓶标识绑定的用户账户信息开通预授权或者预扣费，由此实现无关充电的开通。这样，对于已注册的用户， 当需要充电时，只要将电动车的电瓶与充电电源连接，充电电源能够自动读取电瓶标识后通过PLC电力载波通信方式发送到网关，网关将电瓶标识发送到后台服务器，后台服务器基于电瓶标识查询绑定的用户账户信息，若该用户账户信息已开通预授权或者预扣费，则网关控制充电电源对电瓶车继续充电，若没有开通预授权或者预扣费，则停止充电。
另一方面，如果是对于未注册用户，需要充电时，通过将电动车的电瓶与充电电源连接，充电电源能够自动读取电瓶标识后通过PLC电力载波通信方式发送到网关，网关电瓶标识显示给用户，用户通过移动终端的公众号或者小程序等方式将电瓶标识和用户账户信息发送到后台服务器，由后台绑定电瓶标识和用户账户信息，并且在对该用户账户信息开通预授权或者预扣费之后，网关控制充电电源对电瓶车继续充电，若没有开通预授权或者预扣费，则停止充电。
本发明还提供一种计算机设备，包括：存储器；处理器；以及存储在所述存储器上并可在所述处理器上运行的计算机程序，其中，该计算机程序的运行使得所述处理器执行所述计算机程序时实现上述的电动车的充电方法。
如上所述，根据本发明的电动车的充电系统以及电动车的充电方法，能够提供一种便捷的无感充电开通方法，对于未注册或已注册用户都能够提供一种方便的信息读取和绑定方式，简化用户开通流程。而且，为了降低该场景中无感支付扣款失败的风险，采用预授权方式降低无法扣款的风险。
以上例子主要说明了本发明的电动车的充电系统以及电动车的充电方法。尽管只对其中一些本发明的具体实施方式进行了描述，但是本领域普通技术人员应当了解，本发明可以在不偏离其主旨与范围内以许多其他的形式实施。因此，所展示的例子与实施方式被视为示意性的而非限制性的，在不脱离如所附各权利要求所定义的本发明精神及范围的情况下，本发明可能涵盖各种的修改与替换。
