Description

充电方法、网关设备、充电服务设备、平台、系统和介质
本申请要求于2021年01月29日提交的、申请号为202110123845.X、标题为“充电方法、网关设备、充电服务设备、平台、系统和介质”的中国专利申请的优先权，该中国专利申请的公开内容以引用的方式并入本文。
技术领域
本申请属于充电消费设备的充电技术领域，具体涉及一种充电方法、网关设备、充电服务设备、管理平台、充电系统及计算机可读存储介质。
背景技术
本部分旨在为权利要求书中陈述的本申请的实施方式提供背景或上下文。此处的描述不因为包括在本部分中就承认其为现有技术。
目前，利用充电桩对电动汽车进行充电时的支付方式有两种：一种为扫码支付，另一种为刷卡支付。
对于扫码支付方式，其通过手机向指定充电桩上的充电交易进行授权，授权完成后通过管理平台启动充电桩以进行充电，在整个过程中电动汽车与充电桩之间无数据交互。对于刷卡支付方式，其通过支付卡(例如银行卡)向指定充电桩上的充电交易进行授权，授权完成后充电桩自动启动充电，整个过程电动汽车与充电桩之间同样无数据交互。
在支付方式上，扫码支付方式需要用户在每次充电前使用手机进行扫码操作，但是受制于充电站所处位置(如地下停车场)的移动网络信号往往较弱以及充电桩二维码可能不清晰(如强光下反光、阴暗处显得模糊)等问题，通过扫码支付方式启动充电桩的操作容易失败，从而影响用户体验。刷卡支付方式需要用户办理实体支付卡，且支付卡往往只能在特定充电站使用，所以车主往往需要办理多张支付卡，使用繁琐且容易遗失，导致用户体验差。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。 相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
在本申请中，应理解，诸如“包括”或“具有”等术语旨在指示本说明书中所公开的特征、数字、步骤、行为、部件、部分或其组合的存在，并且不旨在排除一个或多个其他特征、数字、步骤、行为、部件、部分或其组合存在的可能性。
另外还需要说明的是，在不冲突时，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
图1为根据本申请实施例的充电系统的场景示意图。管理平台管理业务数据。网关设备负责管理平台与充电服务设备之间的通信，并且网关设备具有一定业务逻辑。充电服务设备为充电消费设备充电，并且充电服务设备与充电消费设备之间存在数据交互。充电消费设备与管理平台之间可通过车联网(也可以是移动通信网络)实现通信。
充电服务设备是提供电能的设备，例如是充电桩。充电消费设备是接收电能的设备，例如是电动汽车、智能手机等。
图2为根据本申请一实施例的充电方法的流程示意图，该方法用于实现对充电消费设备充电，在该流程中，从设备角度而言，执行主体可以是网关设备；从程序角度而言，执行主体相应地可以是搭载于这些网关设备上的程序。网关设备具备一定的业务数据处理能力，其可以是边缘计算网关。
图2中的流程可以包括以下步骤101～步骤104。
步骤101、在从充电服务设备接收到充电凭证请求时，确定对应于所述充电服务设备的本次请求行为的充电凭证。
结合图6，一个网关设备G1或G2通常会连接多个充电服务设备P1至P3或P4至P6，一个充电系统中通常会设置多个网关设备。
当有充电消费设备与一个充电服务设备相连(例如是这个充电服务设备的充电端口与该充电消费设备连通)，这个充电服务设备会向其连接的网关设备请求充电凭证。充电凭证是一串编码，在整个系统中标识本次充电服务。
各个网关设备彼此独立地为其连接的充电服务设备确定充电凭证。
步骤102、将所述充电凭证经由所述充电服务设备发送至与所述充电服务设备相连的充电消费设备，以供所述充电消费设备将所述充电凭证与所述充电消费设备的标识信息发送至管理平台。
网关设备将确定出的充电凭证发送至发送充电启动请求信息的充电服务设备。进而该充电服务设备将该充电凭证发送至与其相连的充电消费设备。该充电消费设备将接收到的充电 凭证与自身的标识信息发送至管理平台。由此，管理平台能够建立充电凭证与充电消费设备的对应关系。
充电消费设备的标识信息是标识该充电消费设备身份的信息，例如是车辆识别码VIN。
管理平台从充电消费设备接收到该充电消费设备的标识信息后，进而能够校验该充电消费设备的车主是否为该充电消费设备绑定了支付账户。进一步，可选地，管理平台还可以验证该支付账户是否对该管理平台开通了小额免密支付业务。
若该充电消费设备的用户已经预先为该充电消费设备在该管理平台的充电业务绑定了支付账户或者进一步为该支付账户对该管理平台开通了小额免密支付，则能够执行后续的充电及支付的流程。
若该充电消费设备的用户没有为该充电消费设备在该管理平台的充电业务开通小额免密支付，后续步骤中，管理平台、网关设备及充电服务设备构成的系统仍可以按照背景技术中介绍的方式为充电消费设备提供充电服务，或者，管理平台提示该充电消费设备的用户为该管理平台的充电业务绑定支付账户或进一步对该管理平台的充电业务开通小额免密支付。
步骤103、在从所述管理平台接收到所述充电凭证和订单号时，向所述充电服务设备发送充电启动指令。
管理平台对从充电消费设备接收到的充电消费设备的标识信息校验通过后，管理平台会记录充电凭证与充电消费设备的标识信息之间的对应关系。
管理平台能够确定该充电凭证与该网关设备的对应关系。在一些实施例中，二者的对应关系是由事先确定的规则所确定的。在另一些实施例中，二者的对应关系是管理平台与网关设备以交互的方式共同确定的。
管理平台为本次充电服务生成订单号，随后向该网关设备一起发送充电启动指令、该网关设备对应的充电凭证、以及订单号。
网关设备接收到充电启动指令、该网关设备对应的充电凭证、以及订单号后，能够根据充电凭证确定出应当启动其所连的哪一个充电服务设备。进而，该充电服务设备能够向其所连的充电消费设备提供充电服务。
在另一种变式中，管理平台为本次充电服务生成订单号，随后向该网关设备一起发出该网关设备对应的充电凭证、以及订单号。
网关设备接收到该网关设备对应的充电凭证、以及订单号后，能够根据充电凭证确定出应当启动其所连的哪一个充电服务设备。进而，该充电服务设备能够向其所连的充电消费设备提供充电服务。
即网关设备被配置为在同时接收到充电凭证和订单号的情况下，判断该充电凭证在管理平台端已验证通过。
需要说明的是管理平台向网关设备发出的充电启动指令和网关设备向充电服务设备发出的充电启动指令在形式上可以相同也可以不同。
至此，充电服务的启动过程无需用户操作移动终端或办理充值卡。
步骤104、将所述充电服务设备本次充电服务的计费相关信息以及所述订单号发送至所述管理平台。
在一些实施例中，当用户断开充电消费设备与充电服务设备的连接或者二者保持连接但充电服务终止后，充电服务设备确定出充电量之后，可以由充电服务设备计算充电费用，进而将计算出的充电费用发送至网关设备。
在一些实施例中，当充电服务结束后，充电服务设备也可将充电量发送至网关设备，由网关设备计算充电费用。
在一些实施例中，当充电服务结束后，充电服务设备将充电量发送至网关设备，网关设备再将充电量发送至管理平台，由管理平台计算充电费用。
故费用相关信息可以是充电量，也可以是充电费。
由于网关设备具备一定的业务处理能力，为降低管理平台的程序的复杂程度即运算量，可选择网关设备根据充电量计算充电费。
由于管理平台能够建立充电凭证与充电消费设备的身份信息的对应关系以及充电凭证与订单号的对应关系，当管理平台从网关设备接收到计费相关信息和订单号后，能够根据订单号确定该充电消费设备所对应的支付账户，进而管理平台能够直接向该支付账户发起扣费操作。当然，如果该支付账户已为该管理平台的充电业务开通免密支付，则扣费过程也无需用户参与。
如将该充电方法应用于对电动汽车的充电服务，用户无需通过手机扫码的方式启动对电动汽车的充电，也无需事先办理充值卡，用户的操作得到极大简化。进一步电动汽车可通过车联网实现与管理平台的信息交互，电动汽车与充电桩以有线的方式进行信息交互，用户手机信号质量对充电过程的影响也得到了降低。如用户对管理平台开通免密支付的授权，则充电的全程无需用户对自己的智能手机等移动终端进行操作。
图3为根据本申请一实施例的充电方法的流程示意图，该方法用于实现对充电消费设备的充电服务，在该流程中，从设备角度而言，执行主体可以是充电服务设备；从程序角度而言，执行主体相应地可以是搭载于这些充电服务设备上的程序。该充电方法与前述的充电方法是基于相同的发明构思。该方法可以包括以下步骤。
步骤201、在检测到自身与充电消费设备相连时，向网关设备发送充电凭证请求，以获取充电凭证。
步骤202、在接收到充电凭证时，将所述充电凭证发送至所连充电消费设备，以供所述充电消费设备将自身的标识信息和所述充电凭证发送至管理平台。
步骤203、在从所述网关设备接收到充电启动指令时，启动对所述充电消费设备充电。
步骤204、在检测到充电服务结束时，向所述网关设备发送计费相关信息。
充电服务结束的情况例如是充电服务设备与充电消费设备断开连接，或者是用户在充电服务设备上点击结束充电的按钮等。
充电服务设备向与其所连的充电消费设备发送充电凭证，从而充电消费设备能够向管理平台发送身份信息和该充电凭证。这使得管理平台能够根据该充电凭证对该身份信息所关联的支付账户发起扣费操作。
图4为根据本申请一实施例的充电方法的流程示意图，该方法用于实现充电消费设备的充电，在该流程中，从设备角度而言，执行主体可以是管理平台；从程序角度而言，执行主体相应地可以是搭载于管理平台上的程序。该充电方法与前述的充电方法是基于相同的发明构思。该方法可以包括以下步骤。
步骤301、从充电消费设备接收充电凭证和所述充电消费设备的标识信息，其中，所述充电凭证对应一网关设备。
步骤302、对所述标识信息进行校验，并在所述标识信息校验通过时，生成与所述充电凭证关联的订单号。
步骤303、将所述充电凭证以及所述订单号一起发送至所述充电凭证对应的网关设备，以供所述网关设备根据充电启动指令向所述充电凭证对应的充电服务设备发出充电启动指令，其中，所述网关设备维护充电凭证与充电服务设备的对应关系。
步骤304、从所述网关设备接收计费相关信息和所述订单号，根据所述订单号查找对应的充电消费设备标识信息所关联的支付账户，根据所述计费相关信息向查找到的支付账户发起扣费操作。
充电凭证与一个订单号相对应，充电凭证与一个网关设备相对应，充电凭证还与一个充电消费设备相对应，从而管理平台可以根据订单号找到对应的充电凭证，根据充电凭证找到该充电消费设备的车主在该管理平台绑定的支付账户，进而向该支付账户发起扣款操作。
图5为根据本申请一实施例的充电方法的流程示意图，该方法用于至少实现充电消费设备的充电以及支付的发起，在该流程中，从设备角度而言，执行主体可以是管理平台、网关设备和充电服务设备构成的充电系统；从程序角度而言，执行主体相应地可以是搭载于管理 平台、网关设备和充电服务设备上的程序。该充电方法与前述的充电方法是基于相同的发明构思。该方法可以包括以下步骤。
步骤401、充电服务设备在检测到有充电消费设备与其相连时，向网关设备获取充电凭证。
步骤402、所述充电服务设备将获取到的充电凭证发送至与其相连的充电消费设备，以供所述充电消费设备将自身标识信息和所述充电凭证发送至管理平台。
步骤403、所述管理平台在对所述标识信息进行校验，且校验通过时生成与所述充电凭证关联的订单号。
步骤404、所述管理平台将所述充电凭证、以及与所述充电凭证关联的订单号一起发送至所述充电凭证对应的网关设备，其中，所述管理平台维护充电凭证与网关设备的对应关系、充电凭证与消费设备标识信息的对应关系、充电凭证与订单号的对应关系。
步骤405、所述网关设备向所述充电凭证对应的充电服务设备发出充电启动指令，其中，所述网关设备维护充电凭证与充电服务设备的对应关系。
步骤406、所述充电服务设备根据接收到的充电启动指令启动对所连充电消费设备充电，并在检测到充电服务结束时，向所述网关设备发送计费相关信息。
步骤407、所述网关设备查找发送计费相关信息的充电服务设备所关联的充电凭证，根据查找到的充电凭证查找对应的订单号，将查找到的订单号以及对应的计费相关信息发送至所述管理平台。
步骤408、所述管理平台根据所述订单号查找对应的标识信息所关联的支付账户，根据所述计费相关信息对所述支付账户发起扣款。
图6是一个充电系统的场景图示例，管理平台连接两个网关设备G1、G2，网关设备G1连接充电服务设备P1、P2和P3，网关设备G2连接充电服务设备P4、P4和P6。实际场景中充电服务设备的数量、网关设备的数量都可能是非常大的，例如一个管理平台通过十几个或几十个网关设备连接几十个或上百个充电服务设备。
充电凭证的位数可以比订单号的位数还要多或者相等，从而可以实现任意两个网关设备确定出的充电凭证是不会重复的，并且能够从充电凭证的某些位的数值判断出该充电凭证对应于哪一个网关设备。
如充电消费设备与充电服务设备之间的通信方式是脉冲宽度调制(PWM)方式，电动汽车与充电桩之前的通信速度较慢。为了减少电动汽车与充电桩之间的通信耗时，可以将充电凭证的位数设置的比订单号更短，从而减少电动汽车与充电桩之间的通信数据量，从而减少用户的等待时间。
当然，充电消费设备与充电服务设备之间的通信方式也可以是电力线通信(PLC)方式。
当充电凭证的位数足够短时，由于各网关设备为各次充电服务所确定的充电凭证是独立进行的，需要一定的机制防止在同一时间有两个充电服务设备使用相同的充电凭证。
以图6所示场景为例，结合图7，本申请的实施例还提供所述确定对应于所述充电服务设备的本次请求行为的充电凭证的具体实现方法。从硬件角度而言，该方法的执行主体为网关设备。该方法包括以下步骤。
步骤501、生成初选充电凭证。
网关设备可以随机生成一个初选充电凭证，也可以按照从0到最大值再到0的循环的方式每次都将上一次确定的充电凭证加1得到本次的初选充电凭证。当然，为减少初选充电凭证冲突的概率，每个网关设备启动后所生成的第一个初选充电凭证可以是等差分布的。
步骤502、将所述初选充电凭证发送至所述管理平台，以供所述管理平台验证所述初选充电凭证当前是否被占用。
一个充电凭证当前被占用，也就是管理平台的记录信息中该充电凭证当前与一个尚未完成支付的订单号相对应。若一个充电凭证对应的订单号已经完成支付，则该充电凭证与该订单号的对应关系解除。
步骤503、响应于所述初选充电凭证当前未被占用，将所述初选充电凭证作为所述充电凭证。
如此，网关设备在确定充电凭证时，需要得到管理平台的确认该网关设备确定出的充电凭证当前是未被占用的。从而避免了同时存在两个充电服务设备对应同一个充电凭证。
进一步，该方法还可以包括步骤504、响应于所述初选充电凭证当前被占用，从所述管理平台接收一个未被占用的充电凭证作为所述充电服务设备对应的充电凭证。
也就是管理平台判定该初选充电凭证已与一个订单号对应，且该订单号尚未完成支付，那么管理平台挑选一个未被占用的充电凭证发送给该网关设备。
管理平台可以维护充电凭证与订单号的映射表、充电凭证与网关设备的映射表。网关设备可以维护充电凭证与自身所连充电服务设备的映射表。
与此相对应，对于管理平台实施的充电方法还可以包括：从所述网关设备接收初选充电凭证；判断所述初选充电凭证当前是否被占用，如否则通知所述网关设备所述初选充电凭证当前未被占用。
进一步，如判断所述初选充电凭证当前被占用，则选择一个未被占用的充电凭证，并将挑选出的充电凭证发送至所述网关设备。
网关设备与充电服务设备的连接关系可以是由连线方式决定的，即该连接关系可以是固定的。一旦其中一个网关设备发生故障或一个网关设备与某个充电服务设备的通信连接发生故障，需要运营维护人员去现场进行维修。这极大的增加了人力成本，并且维护的效率较低。为提高整个充电系统的可用性以及可靠性，网关设备与充电服务设备可以是接入同一个局域网，网关设备与充电服务设备的连接关系可以是动态可调的。图8示出的是这种实施方式下的一种充电系统的架构图。其中，充电服务设备通过交换机与网关设备接入同一个局域网。当然，网关设备与管理平台的连接方式可以是有线的，也可以是无线的(例如是通过5G通信网络)，本申请对此不作限定。
对于前述的步骤103可以调整为：在从所述管理平台接收到充电启动指令、所述充电凭证、以及所述充电凭证对应的订单号时，向所述充电凭证对应的充电服务设备发出充电启动指令，以使所述充电服务设备启动对所述充电消费设备充电。
所述网关设备与所述充电服务设备接入同一局域网，所述网关设备与所述充电服务设备以广播的方式通信。
进一步，网关设备所执行的方法还包括：在接收到充电服务设备向所述局域网广播的连接请求时，向所述充电服务设备发送自身的状态信息和IP地址；在接收到所述充电服务设备向所述局域网广播的筛选结果时，如被选中则连接所述充电服务设备与所述管理平台。
如此，网关设备与充电服务设备的连接关系是可调的。
其中，所述自身的状态信息可以包括：当前所连接的充电服务设备的数量。
更进一步，该方法还可以包括：在接收到所述充电服务设备向所述局域网广播的筛选结果时，如未被选中则保存所述充电服务设备与被选中的网关设备之间的通信数据；记录所述管理平台发送的针对所述局域网内其他网关设备所连充电服务设备的订单号及对应的充电凭证。
在同一局域网内，由于所有的网关设备与充电服务设备的通信数据都在其他网关设备存在备份，并且各网关设备记录的当前订单号与充电凭证的对应关系都是相同的，即使一个网关设备宕机，当其他网关设备接替这个宕机的网关设备时，业务数据不会丢失，充电计费的完整流程仍能继续实施。从而提高了系统的稳定性，也能降低运营维护的人力成本。
与此相对应，充电服务设备还执行：向所述局域网广播连接请求；接收所述局域网内的网关设备发送的自身的状态信息和IP地址；根据所述状态信息挑选一个网关设备并将挑选结果广播至所述局域网，其中，被选中的网关设备负责连接所述充电服务设备与所述管理平台；向所述局域网广播与所挑选的网关设备的通信数据。
所述自身的状态信息包括：当前所连接的充电服务设备的数量。例如各网关设备的型号是一样的，那么可以选择当前连接的充电服务设备的数量最少的一个网关设备。当所述局域网内所连充电设备数量最少的网关设备有多个时，从所连充电设备数量最少的网关设备中随机选择一个网关设备。
网关设备进一步可以与充电服务设备通过监听心跳的方式供充电服务设备自行判断其与网关设备的连接是否正常。网关设备所执行的方法进一步可以包括：在接收到所连接的充电服务设备发送的心跳报文时，向所述心跳报文对应的充电服务设备发送响应报文；或者定时向所连接的充电服务设备发送心跳报文。
与此相对应，充电服务设备还执行：定期向所连接的充电服务设备发送心跳报文，如未接收到响应报文的状态持续第一设定时长，则再次向所述局域网广播连接请求；或者在持续第二设定时长未接收到所连接的网关设备发送的心跳报文时，再次向所述局域网广播连接请求。
需要说明的是，由于在同一时刻，单个充电凭证分别对应一个网关设备、一个充电服务设备、以及一个充电消费设备。为使得充电和计费的流程能够完整运行，管理平台不向网关设备反馈订单号的情况下，该系统也是能正常运行的。
相应地，对于网关设备的充电方法而言，其可以包括以下步骤：在从充电服务设备接收到充电凭证请求时，确定对应于所述充电服务设备的本次请求行为的充电凭证；将所述充电凭证经由所述充电服务设备发送至与所述充电服务设备相连的充电消费设备，以供所述充电消费设备将所述充电凭证与所述充电消费设备的标识信息发送至管理平台；在从所述管理平台接收到充电启动指令、所述充电凭证时，向所述充电服务设备发送充电启动指令；将所述充电服务设备本次充电服务的计费相关信息以及所述充电凭证发送至所述管理平台。
相应地，对于管理平台的充电方法而言，其可以包括以下步骤：从充电消费设备接收充电凭证和所述充电消费设备的标识信息，其中，所述充电凭证对应一网关设备；对所述标识信息进行校验，并在所述标识信息校验通过时，将充电启动指令、所述充电凭证一起发送至所述充电凭证对应的网关设备，以供所述网关设备根据充电启动指令向所述充电凭证对应的充电服务设备发出充电启动指令，其中，所述网关设备维护充电凭证与充电服务设备的对应关系；从所述网关设备接收计费相关信息和所述充电凭证，根据所述充电凭证查找对应的充电消费设备标识信息所关联的支付账户，根据所述计费相关信息向查找到的支付账户发起扣费操作。
对于充电服务设备而言，其运行的充电方法与前述实施例中充电服务设备的充电方法是相同的。
从充电服务设备、网关设备和管理平台三者构成的系统角度而言，该方法包括：
充电服务设备在检测到有充电消费设备与其相连时，向网关设备获取充电凭证；
所述充电服务设备将获取到的充电凭证发送至与其相连的充电消费设备，以供所述充电消费设备将自身标识信息和所述充电凭证发送至管理平台；
所述管理平台在对所述标识信息进行校验，且校验通过时将充电启动指令、所述充电凭证一起发送至所述充电凭证对应的网关设备，其中，所述管理平台维护充电凭证与网关设备的对应关系、充电凭证与消费设备标识信息的对应关系；
所述网关设备根据接收到的充电启动指令向所述充电凭证对应的充电服务设备发出充电启动指令，其中，所述网关设备维护充电凭证与充电服务设备的对应关系；
所述充电服务设备根据接收到的充电启动指令启动对所连充电消费设备充电，并在检测到充电服务结束时，向所述网关设备发送计费相关信息；
所述网关设备查找发送计费相关信息的充电服务设备所关联的充电凭证，将查找到的充电凭证以及对应的计费相关信息发送至所述管理平台；
所述管理平台根据所述充电凭证查找对应的标识信息所关联的支付账户，根据所述计费相关信息对所述支付账户发起扣款。
需要说明的是，前述实施例中的各种具体的实现方式同样适用于这种变形。故在此不做赘述。
结合图8，以下介绍几个充电过程的实例。
如图8所示，管理平台管理两个充电站，每个充电站包含3个充电桩、2个网关设备，充电桩与网关设备通过交换机接入同一局域网络，充电站1的局域网络为192.168.1.0/24，充电站2的局域网络为192.168.2.0/24，充电桩与网关设备的ip地址如下表所示。
设备 编号 ip地址
网关设备 G1 192.168.1.1
网关设备 G2 192.168.1.2
充电桩 P1 192.168.1.3
充电桩 P2 192.168.1.4
充电桩 P3 192.168.1.5
充电桩 G3 192.168.2.1
充电桩 G4 192.168.2.2
充电桩 P4 192.168.2.3
充电桩 P5 192.168.2.4
充电桩 P6 192.168.2.5
网关设备与管理平台连接的方式不限。管理平台保存车辆V1、V2……V6的VIN码及其对应的支付账户，且支付账户已对该管理平台开通小额免密支付。充电过程如下。
S1：充电桩P1启动后，向网段192.168.1.0/24发送广播报文，报文类型为充电桩寻找网关设备。
S2：网关设备G1收到该报文后，将自身ip地址192.168.1.1及所连接的充电桩数量0回复给充电桩P1；网关设备G2收到该报文后，将自身ip地址192.168.1.2及所连接的充电桩数量1回复给充电桩P1。
S3：充电桩P1收到网关设备G1和网关设备G2的回复，由于网关设备G1的充电桩连接数小于网关设备G2的充电桩连接数，所以充电桩P1选择网关设备G1作为通信网关设备，充电桩P1将自身的默认网关设备置为网关设备G1的ip地址192.168.1.1，并将充电桩编号P1及网关设备选择结果G1返回给网关设备G1和网关设备G2。
S4：网关设备G1收到网关设备选择结果报文后，在本地记录充电桩P1的ip地址及充电桩编号P1；网关设备G2收到网关设备选择结果报文后，在本地记录充电桩P1的ip地址、充电桩编号P1及其对应的通信网关设备ip地址192.168.1.1。
S5：充电桩P1选择网关设备G1后，向网关设备G1签到并持续向网关设备G1发送心跳报文。
S6：电动汽车V1被插入充电桩P1的充电枪枪后，充电桩P1向网关设备G1请求充电凭证，网关设备G1生成初选充电凭证0001；该请求同样发送至网关设备G2，G2仅做记录。
S7：网关设备G1将初选充电凭证0001发送至管理平台，此时管理平台的0001订单号并未使用，管理平台记录0001及其对应的网关设备G1，生成与充电凭证0001关联的订单号20200923G100018888，并向网关设备G1返回初选充电凭证0001有效的确认信息；
S8：网关设备G1将充电凭证0001以广播的形式返回至充电桩P1，充电桩P1使用PWM技术将充电凭证0001发送给电动汽车V1；网关设备G2将充电凭证0001与充电桩P1的对应关系保存在本地；
S9：电动汽车V1收到充电凭证0001后使用车联网将充电凭证0001及车辆VIN码SSVUDDTT2J2022558透传至管理平台；
S10：管理平台校验VIN码SSVUDDTT2J2022558，该VIN码已开通免密充电服务，管理平台将订单号20200923G100018888与车辆VIN码SSVUDDTT2J2022558进行关联，并从记录中找到充电凭证0001对应的网关设备G1；
S11：管理平台向网关设备G1和G2下发充电启动指令及订单号20200923G100018888、充电凭证0001，网关设备G1根据充电凭证0001找到其对应的充电桩P1，以广播的形式控制其启动充电，网关设备G2仅记录充电凭证0001与订单号20200923G100018888的对应关系；
S12：充电桩P1充电完成后，充电桩P1以广播的形式向网关设备G1和G2报告充电量，网关设备G1根据计费规则完成充电费用计算，并将充电费用随订单号20200923G100018888上送管理平台；
S13：管理平台根据订单号20200923G100018888关联的电动汽车V1获取其对应的支付账户，并从中完成自动扣费。
电动汽车V1进行充电的期间，电动汽车V4使用充电桩P4进行充电，并且此时充电桩P4已经选取网关设备G3处理其与管理平台的通信。网关设备G3生成充电凭证0001上送管理平台。此时，管理平台发现0001正在被使用，则生成未被使用的充电凭证0002，之后将充电凭证0002返回至网关设备G3。网关设备G3将充电凭证0002经充电桩P4发送至电动汽车V4，再由电动汽车V4将自身的标识信息与充电凭证0002发送至管理平台。管理平台对电动汽车V4的标识信息校验通过生成订单号20200923G200026666，并将充电启动指令、订单号20200923G200026666与充电凭证0002一起返回给网关设备G3和G4，网关设备G3使用充电凭证0002找到充电桩P4，启动充电桩P4的充电流程。
网关设备宕机的处理方式如下。
假定网关设备G1宕机后，充电桩P1的发出心跳报文连续多次没有收到回复信息，达到一定次数后，充电桩P1向局域网络192.168.1.0/24发送广播报文，报文类型为更换通信网关设备(也可以是等效的充电桩寻找网关设备的报文)。如步骤S1-步骤S13一样，充电桩P1更换通信网关设备为网关设备G2，并向网关设备G2通报当前充电凭证0001，网关设备G2根据充电凭证0001找到对应的充电记录，并继续进行相关充电支付流程。
