具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在现有的电动汽车充电站中，不同的充电设施可能具有不同特点，比如，充电设施分为直流充电设施和交流充电设施，分别采用直流充电方式和交流充电方式，又比如，不同国家、不同地区甚至不同品牌车辆的充电标准呈现多样化等等，这些原因导致同一充电设施不能为不同充电要求的电动汽车进 行充电。因此，本申请提供了一种充电设施通信控制器，又称供能装置通信控制器(Supply Equipment Communication Controller，简称SECC)，该SECC可以将不同充电设施的功能统一化，如果将SECC集成或外接于现有的每一充电设施中，不但可以实现直流充电和交流充电，并对这两种充电方式进行充电控制，还可以支持不同国家、不同地区甚至不同品牌车辆的充电标准，从而使得每一电动汽车可以使用每一充电设施进行充电。
参见图1所示的充电系统架构示意图，针对现有的直流充电设施和交流充电设施，提供充电设施、电动汽车以及云端服务器三者之间的数据交互服务，其中，充电设施中集成了SECC，SECC可以为电动汽车提供即插即充的充电服务，也就是说，用户仅需将充电设施连接电动汽车，充电设施即可对电动汽车进行身份验证、授权、充电、计费结算等一系列操作，实现无人值守的自动充电。
下面基于图1所示系统架构介绍本实施例提供的SECC。
在本实施例中，将利用充电设施进行充电的电动汽车称为目标车辆。
参见图2，为本实施例提供的一种充电设施通信控制器SECC的组成示意图，该SECC包括：
处理器模块201，用于采用为目标车辆选择的目标充电方式、以及所述目标车辆支持的目标充电标准，输出对所述目标车辆的充电控制参数；其中，所述目标充电方式为交流充电方式或直流充电方式，所述目标充电标准是从所述充电设施通信控制器支持的各种充电标准中选择的；
充电控制模块202，用于根据所述处理器模块201输出的充电控制参数，控制对所述目标车辆的充电动作。
在现有的充电设施中，有交流充电设施和直流充电设施，分别采用交流充电方式和直流充电方式，两者在电流、电压等技术参数上都有较大差距，前者充电效率较低，而后者充电效率较高。其中，交流充电设施与交流电网连接，为电动汽车车载充电机提供单向交流电源或三相交流电源，交流充电设施本身并不具备充电功能，其只是单纯的提供电力输出，还需要连接电动汽车车载充电机，方可起到为电动汽车电池充电的作用，但是，由于电动汽车车载充电机的功率一般都比较小，所以交流充电设施无法实现快速充电；直流充电设施也与交流电网连接，但与交流充电设施不同的是，直流充电设 施具备充电功能,其可以为电动汽车的动力电池提供直流电源，具体可以提供足够的功率、输出的电压和电流调整范围大，可以实现快充的要求。
而在本实施例中，SECC可以负责充电系统的任务调度、数据处理及控制。具体地，SECC同时支持直流充电方式和交流充电方式，即，参见图1，当目标车辆通过充电线缆与充电设施连接、并通过充电设施或其它方式为目标车辆选择了直流充电方式后，SECC可以通过控制充电控制器为目标车辆提供直流电流，实现快速充电；传统的交流充电设施内部没有充电控制器，其只单纯的提供电力输出，本实施例与传统交流充电设施不同的是，当目标车辆通过充电线缆与充电设施连接、并通过充电设施或其它方式为目标车辆选择了交流充电方式后，SECC可以作为整个充电设施的控制和通信终端使用，也就是说，SECC不仅可以为目标车辆提供电力输出，还可以对交流充电方式进行控制，并基于控制结果为目标车辆进行交流充电。
此外，SECC还兼容了现有的多种充电标准，这样，SECC的处理器模块201可以与目标车辆交互，以获取目标车辆相关信息，或者，与云端服务器交互，以获取预先登记在云端的目标车辆相关信息，其中，所述相关信息可以是车辆型号、车牌号等，可以预先建立目标车辆相关信息与充电标准的对应关系，并基于该对应关系确定该目标车辆支持的充电标准，之后，根据目标车辆支持的充电标准为目标车辆进行充电。
这样，处理器模块201便可以根据充电方式和充电标准向充电控制模块202下发控制参数，当充电设施具备充电控制器时，充电控制模块202可以利用充电控制器对目标车辆实施充电动作；当充电设施不具备充电控制器时，充电控制模块202可以直接对目标车辆实施充电动作。
可以理解的是，如果为目标车辆选择的充电方式为直流充电方式，则采用的充电标准为目标车辆支持的直流充电标准；如果为目标车辆选择的充电方式为交流充电方式，则采用的充电标准为目标车辆支持的交流充电标准。当然，不同充电方式和充电标准的组合，将具有相应的充电控制参数，这些充电控制参数包括充电电流、充电电压、充电功率等等。
为便于说明本实施例提供的处理器模块201和充电控制模块202，现以一种应用场景为例来说明：
当用户驾驶电动汽车到充电站后，可以利用充电站提供的充电设备为电 动汽车充电，具体地，用户先将充电设备上的充电线缆与电动汽车连接，然后通过充电设备或其它方式为目标车辆选择充电方式，此时，处理器模块201可以通过充电控制模块202与电动汽车通信，以获取电动汽车的品牌、型号等信息，用来确认电动汽车支持的充电标准，之后，处理器模块201根据选择的充电方式以及目标车辆支持的充电标准生成充电控制参数，即生成相应的充电电压、充电电流、充电功率等。
例如，以北美地区的某充电标准为例：采用交流充电时，电压最高250V，电流最大32A，而采用直流充电时，电压最高600V，电流最大可达200A；此外，交流充电标准与直流充电标准的充电功率也会不同。其中，相应的充电方式还可以对应一种或多种充电方法，比如恒流充电法、恒压充电法、快速充电法等充电方法，用户可以选择相应的充电方法或者接受充电设备默认的充电方法，则处理器模块201可以在充电标准要求的电压、电流、功率等充电控制参数的限制下，生成与该充电方法适合的充电控制参数。
接下来，充电控制模块202根据处理器模块201输出的充电控制参数，通过控制充电控制器的动作，使电网为电动汽车提供电能，或者直接使电网为电动汽车提供电能。
综上，本实施例提供的一种充电设施通信控制器，包括处理器模块和充电控制模块，处理器模块采用预先为目标车辆选择的目标充电方式、以及目标车辆支持的目标充电标准，对目标车辆进行充电控制；之后，充电控制模块根据处理器模块输出的充电控制参数，对目标车辆实施充电动作。可见，本实施例不但可以实现直流充电和交流充电，并对这两种充电方式进行充电控制，还可以支持不同国家、不同地区甚至不同品牌车辆的充电标准，从而满足不同电动汽车的充电需求。
参见图3，为本实施例提供的处理器模块的组成示意图。下面结合图3对SECC的处理器模块201进行具体介绍。
处理器模块201可以包括：云端交互子模块2011，用于与云端服务器进行信息交互，获取交互结果；充电主控子模块2012，用于采用为目标车辆选择的目标充电方式、以及所述目标车辆支持的目标充电标准，根据所述交互结果输出对所述目标车辆的充电控制参数。
在本申请的一种实施方式中，所述云端交互子模块2011，可以具体用于 接收云端服务器下发的充电曲线，所述充电曲线是通过分析当前电网负荷情况和/或电网能源类型生成的充电曲线；所述充电主控子模块2012，可以具体用于采用为目标车辆选择的目标充电方式、以及所述目标车辆支持的目标充电标准，根据所述充电曲线输出对所述目标车辆的充电控制参数。
在本实施方式中，SECC可以通过与云端服务器进行交互实现能量均衡。具体地，SECC的云端交互子模块2011可以向云端服务器发出请求，请求云端服务器分析当前电网负荷情况和/或电网能源类型，计算最优的充电曲线并返回给云端交互子模块2011，以便充电主控子模块2012利用该充电曲线对接入电网的目标汽车进行充电控制。一种方式是，根据当前电网负荷情况进行充电控制，比如，在用电低谷时对目标汽车进行快速充电，而在用电高峰时停止充电，同时目标汽车向电网回馈能量，从而缓解电网负担，实现电网负荷峰谷的转移；另一种方式是，根据能源类型进行充电控制，比如，可以对比不同能源类型(如太阳能、风能、水能、火电站等)在相同时间内输出的能量大小限制充电速度；再一种方式是，根据不同的用电时段和能源类型进行充电控制。此外，本实施例还可以结合不同的用电时段和能源类型调整电费价格，也可使用户避开在用电高峰时段充电。
可见，云端服务器通过对当前电网的负荷情况计算充电曲线，动态的控制对目标车辆的充电时机，以调整用电峰谷时间，缓解了因集中充电对电网造成的冲击。
在本申请的一种实施方式中，还可以在充电之前验证目标车辆的合法性，只允许对合法车辆进行充电，因此，所述处理器模块201还可以进一步包括：
充电授权子模块2013，用于输出对所述目标车辆的充电控制参数之前，确认对所述目标车辆的充电授权。在本实施方式中，用户将目标车辆与充电设施连接后，充电设施即可对目标车辆进行身份验证，当其身份合法时，才触发充电主控子模块2012对目标车辆进行充电控制。
对本实施方式进行具体实现时，所述充电授权子模块2013，可以用于获取所述目标车辆的车辆身份信息；所述云端交互子模块2011，可以用于将所述车辆身份信息上传至所述云端服务器；所述充电授权子模块2013，还可以用于接收所述云端服务器下发的身份认证消息，所述身份认证消息携带了根据所述车辆身份信息对所述目标车辆进行的身份认证结果；接下来，所述充 电主控子模块2012，可以用于当所述身份认证结果表示认证通过后，采用为目标车辆选择的目标充电方式、以及所述目标车辆支持的目标充电标准，输出对所述目标车辆的充电控制参数。
在该具体实施方式中，参见图1，充电授权子模块2013与目标车辆的车载控制器(Electric Vehicle Communication Controller，简称EVCC)进行交互，从EVCC获取目标车辆的车辆身份信息，比如车牌号、车辆类型等车辆身份信息，并将该车辆身份信息上传至云端服务器，以便云端服务器根据车辆身份信息对目标车辆进行身份认证；然后，充电授权子模块2013，获取经云端服务器计算后返回的验证结果，根据认证结果确认充电授权后，由充电主控子模块2012开始对目标车辆充电。
在本申请的一种实施方式中，安装了SECC的充电设施，还可以对充电设施进行远程的固件升级，以降低运营维护成本，因此，所述云交互子模块2011，具体可以用于通过与所述云端服务器进行通信，以完成所述云端服务器对充电设施的固件升级；所述充电主控子模块2012，具体用于采用为目标车辆选择的目标充电方式、以及所述目标车辆支持的目标充电标准，基于固件升级结果输出对所述目标车辆的充电控制参数。
在本实施方式中，SECC可以利用云交互子模块2011与云端服务器进行通信，通过云端服务器对SECC进行远程的软件固件在线升级，这种远程固件升级方式无需人员现场操作，可减少充电设施运用维护成本，提高充电设施升级效率，这样，充电主控子模块2012便可以基于升级后的软件固件对目标车辆进行充电控制。
现有的充电计费结算方式，大多是以人工计费或刷电费卡为主要方式，这使充电站的运营和使用受到了一定的限制，为解决该缺陷，本实施例提供了自动充电计费结算功能，因此，在本申请的一种实施方式中，所述处理器模块201还可以进一步包括：计费结算子模块2014，用于对所述目标车辆完成充电后，根据充电结果计算充电费用并进行计费结算，参见图3。
在本实施方式中，计费结算子模块2014可以根据当前电价、充电电量等自动计算充电费用，进而完成计费结算，例如，用户可以预先在云端服务器登记结算方式，比如登记一张用于充电结算的用户卡，当计费结算子模块2014计算出充电费用后，可以从云端服务器获取目标车辆对应的用户卡信息并直 接从该用户卡上划取充电费用，从而实现自动结算。
在本实施例中，对于上述处理器模块201包括的云端交互子模块2011、充电主控子模块2012、充电授权子模块2013、以及计费结算子模块2014，其中的一个或多个模块的功能可以采用中央处理器(Central Processing Unit，简称CPU)实现；此外，上述处理器模块201还可以包括电可擦可编程只读存储器(Electrically Erasable Programmable Read-Only Memory，简称EEPROM)和嵌入式多媒体卡(Embedded Multi Media Card，简称EMMC)，使EEPROM和EMMC分别用于充电相关数据的存储和系统的在线升级。
参见图4所示的另一种充电设施通信控制器的组成示意图，在本实施例中，SECC还可以包括通信模块203，通信模块203还可以包括云通信单元，云通信单元可以使用OCPP标准通信协议与云端服务器连接，采用以太网/GPRS/4G等方式进行通信，使目标车辆的身份信息上传云端服务器进行验证，验证通过后即可控制充电设施开始充电，并根据不同能源类型和用电时段调整计费价格，如此即可实现无人值守的即插即充充电服务；还通过云通信单元对充电设施进行远程的固件升级，降低了运营维护成本。
参见图5，为本实施例提供的充电控制模块的组成示意图。下面结合图5对SECC的充电控制模块202进行具体介绍。
在本申请的一种实施方式中，所述充电控制模块202可以包括：
数据交互子模块2021，用于通过与所述目标车辆的车载控制器进行通信，获取所述目标车辆的充电状态信息，并将所述充电状态信息发送至所述处理器模块201；接收所述处理器模块201根据所述充电状态信息下发的充电控制参数；充电控制子模块2022，用于根据所述充电控制参数，控制对所述目标车辆的充电动作。
在本实施方式中，充电设施的SECC与目标车辆的EVCC进行电力线载波(Power Line Communication，简称PLC)通信，其中，PLC信号加载在CP线上。SECC的数据交互子模块2021可以与目标车辆的EVCC进行控制引导线(即CP线)上的PLC通信，以交换充电信息。例如，充电前，交互所述车辆身份信息；充电过程中，交互充电状态信息(比如电压、电流、温度、电池电量、错误报告等)、充电控制命令等，并将这些信息上传至处理器模块201的充电主控子模块2012，充电主控子模块2012会根据交互的充电信息以及从云端服 务器下发的充电曲线，生成控制参数，以便充电控制子模块2022根据该控制参数实现对目标车辆的智能充电，并通过图1所示的电力线向目标车辆的电池包输送电能，整个充电过程的充电协议兼容ISO15118、DIN70121和J1772等充电标准；充电结束后，交换电池电量与计费信息。
此外，本实施例不但支持以上介绍的有线通信方式以及基于电力线的有线充电方式，还支持无线通信方式以及无线充电方式。具体地，为了实现无线通信方式，充电设施的SECC中的通信模块203还可以支持wifi通信，该通信模块203可以与目标车辆的EVCC进行wifi通信，用以交换充电信息；为了实现无线充电方式，可以为充电设施与目标车辆分别配置电磁感应主线圈和电磁感应副线圈，这样，充电控制子模块2022可以根据控制参数，通过电磁感应主线圈向电磁感应副线圈输送电能，从而实现了充电设施向目标车辆的无线充电。
在本申请的一种实施方式中，充电设施与目标车辆之间可能出现未真正连接的情况，为了保证充电的顺序进行，所述充电控制模块202还可以进一步包括：
连接检测子模块2023，用于预先检测所述目标车辆与所述充电设施之间的物理连接是否可靠，若可靠，则触发所述处理器模块201工作。在本实施方式中，当将目标车辆与充电设施的充电线缆连接后，首先通过连接检测子模块2023检测目标车辆与充电设施的连接可靠性，当连接可靠后，数据交互子模块2021启动PLC数字通信，从目标车辆获取车辆身份信息，并按照上述介绍方式进行身份认证，待认证通过后，按照上述介绍方式为目标车辆进行充电并结算。
在本申请的一种实施方式中，SECC还提供了各种充电设施外设需求的控制接口。在本实施方式中，SECC提供了多种对外设的控制接口，使之可以被灵活的集成在几乎所有的现有充电设施中，具体地，图4所示的通信模块203还可以包括RS485总线通信单元、RS232通信单元和USB通信单元等，每一通信单元可以提供对应的一种控制接口，并将该控制接口作为一个或多个外设的控制接口，比如，电子锁控制接口、充电接触器控制接口、触摸屏控制接口、插枪检测接口、刷卡器接口、电表以及调试接口等。
另外，图4所示的通信模块203还可以包括控制器局域网络(Controller  Area Network,简称CAN)总线通信单元，用于连接充电设施内部的充电控制器，使SECC与充电控制器通信来控制对目标车辆的充电动作。具体地，SECC汇集了与电动汽车之间的PLC通信信息以及与云端服务器间的通信信息，经过协议转换后与充电控制器进行CAN通信，用于控制充电动作，从而实现了电动汽车、云端服务器以及电网三者的互联互通。
进一步地，参见图4，SECC还可以包括电源模块204和外部设备控制模块205，电源模块204主要负责将输入的24V电压转换为5V、3.3V、1.8V和15V，分别为SECC内部的各个芯片以及负载供电，外部设备控制模块205主要负责充电枪锁电机控制以及电网端的接触器控制。
进一步地，本发明实施例还提供了一种充电设施通信控制器的硬件构成。可包括至少一个处理器(例如CPU)，至少一个网络接口或者其他通信接口，存储器，和至少一个通信总线，用于实现这些装置之间的连接通信。处理器用于执行存储器中存储的可执行模块，例如计算机程序。存储器可能包含高速随机存取存储器(RAM：Random Access Memory)，也可能还包括非不稳定的存储器(non-volatile memory)，例如至少一个磁盘存储器。通过至少一个网络接口(可以是有线或者无线)实现该系统网关与至少一个其他网元之间的通信连接，可以使用互联网，广域网，本地网，城域网等。
参见图6，在一些实施方式中，存储器中存储了程序指令，程序指令可以被处理器执行，其中，程序指令可包括处理器模块201、充电控制模块202，或者程序指令还可包括通信模块203、外部设备控制模块205。各单元的具体实现可参见图2或4所揭示的相应模块，这里不再赘述。
