Description

一种车辆及用于认证充电站的方法
技术领域
本发明涉及到一种用于认证充电站的车辆，方法以及系统。

图2为说明用以认证图1中的控制器和充电站的算法的流程图；
图3为说明用以认证图1中的控制器和充电站的另一种算法的流程图。
具体实施方式
电动车辆如今被预期将广泛使用。正在积极开发连接标准，例如J1772(c)。该标准建立了充电站和将连通的车辆充电器之间的通信方法，尤其是充电站的电流限制。可以使用其他技术，例如数字和/或无线通信以通信信息，例如充电站电压和随时间变化的功率限制。有了这些提供的信息，车辆充电器可以将电流提升到充电站的限制值。
可以预期可能发生这种情况：特定车辆和充电站会发现需要确认它们之间(而非第三方)确实有传输电力。也可以预期充电站会监控由车辆充电器汲取的实际电流、功率和能量值以用于收费和其他用途。该监控可以提供由充电站提供的电力、能量等的量的信息。同时，车辆充电器还可以监控从充电站汲取的电力、能量等。考虑到电力损失、系统分辨率以及精确度，如果相互连接，则充电站和车辆充电器在相同的时间间隔期间应当纪录相同的功率，能量等。这些值可以用于确认特定的充电站和车辆确实是相互连接的。
其中，在车辆充电器是充电站的一部分的情况下，牵引电池可监控其电流、功率等。类似地，可将该信息与场外(off-board)充电器和充电站比较以确认该充电站和车辆确实相互连接。
在开始电池充电之前，可以在电力充电站和电动车辆之间建立通信。可以使用已知/合适的有线(例如，电力线通信)或无线(例如，WiFi)技术以实施这样的通信。由于邻近以及其他因素，多个充电站可与单个车辆建立通信。因此可能希望车辆确认从这些充电站中的哪个接收充电能量。
现在参考图1，替代能源车辆10可以包括电机12，变速器14和车轮16。该车辆10还可以包括牵引电池18，电池充电器20以及一个或多个控制器22。(在其它设置中，该电池充电器20可位于车辆外，例如在充电站24中。)如本领域所公知的，电机12配置用于将从牵引电池18接收到的电能转换为机械能以驱动变速器14和车轮16。该电机12还可以配置用于将从变速器14接收的机械能转换为由牵引电池18存储的电能。
该牵引电池18还可以(如虚线所指示的)从电池充电器20接收充电电能。如在下面即将详细叙述的，电池充电器20可以(如虚线所指示的)从远离车辆10的充电站24接收充电电能。还如在下面即将详细描述的，通过/在控制器22控制下，电机12，变速器14，牵引电池18和电池充电器20通信(如细线所指示)。
当车辆10在充电站24附近时，可以在控制器22和充电站24之间建立通信连接(如细线所指示)。如上所提及，可以由已知/合适的有线或无线技术实施该通信连接。在例如有线技术的情况下，可以在控制器22和/或充电站24之间设置电力线通信模块。因此，电池充电器20和充电站24之间的任何电力连接还可以用作为用于通信的信号携带媒介。在例如无线技术的情况下，可以在控制器22和/或充电站24中设置无线收发器。在某些情况下，在控制器22附近可以有多于一个充电站24且与控制器22相通信。
参考图1和图2，在操作26处可以建立与充电站的通信。例如控制器22可以与如上所述的在车辆10附近的一个或多个充电站24建立通信。在操作28处，可以与充电站建立试充电模型(trial charge pattern)。例如，控制器22可以经由在操作26处建立的信道发送指令至充电站24以在特定的时间段内提供特定的功率、电压和/或电流(或其它一些所需参数)。作为响应，充电站24可以发送接收确认以及计时信息使得控制器22和充电站24达成一致的试充电模型的开始时间。在操作30处，可以开始试充电模型。在达成一致的开始时间处，充电站24可以开始在特定时间段内提供特定的功率、电压和/或电流(或者其他所需参数)。在操作32处，测量与从充电站接收到的充电模型相关的参数值。例如，控制器22可以测量、检测等与接收到的能量相关的功率、电压和/或电流。在操作34处，确定测量的参数值是否与达成一致的参数值相等同。例如，控制器22可以确定在该特定的时间段内该测量的功率，电压和/或电流是否大体等于达成一致的试充电模型的功率、电压和/或电流。如果在操作34处得到的结果为是，则在操作36处开始正常的电池充电。例如，控制器22可以请求充电站24提供所需量的功率，能量等至电池充电器20用于给牵引电池18充电。之后结束算法。如果在操作34处得到的结果为否，则在操作38处生成车辆未与正确的充电站配对的提示。例如，控制器22可通过车辆的车辆区域网络广播指示其未与从中接收能量的充电站建立正确通信的消息。随后控制器22则阻止任何进一步的电池充电行为直至解决该问题。
在其他实施例中，如果在操作34处存在差异或者不确定性，则可以选择新的模型并重复该过程。如果预定数量的尝试失败，则控制器22可选择提示其他车辆系统、用户等存在该差异，或者选择开始充电、或者选择不充电等。
可替代地，替代建立试充电模型，控制器22可从充电站24请求一系列的特定功率、电压和/或电流值，例如电压和电流定点值。随后控制器22可确定该请求的值是否等于该测定值。在其他设置中，控制器22可请求充电站24发送关于它们所提供的功率、电压和/或电流值的信息。随后控制器22可确定发送的值是否等于测定值。
参考图1和图3，可以在操作40处与充电站建立通信。例如，控制器22可与如上所述的在车辆10附近的一个或多个充电站24建立通信。在操作42处，可以指示充电站准备提供不高于特定阈值的功率、电流等。例如，控制器22可以指示充电站24准备提供不高于6kW的功率(以120V)。在操作44处，可以从充电站汲取电力。例如，控制器22可使得电池充电器20根据某些随机或预定计划(例如1分钟的3kW功率，随后2分钟的5kW功率)从充电站24汲取电力。在操作46处，可以发送请求至充电站以提供关于所提供功率的信息。例如，控制器22可请求充电站24提供描述所提供功率的量和相关的持续时间的信息。在操作48处，确定关于提供功率的信息是否大体匹配关于汲取的功率的信息。例如，控制器22可确定充电站24是否在1分钟提供3kW功率，随后2分钟提供5kW功率等。如果在操作48处得到的结果为是，则在操作50处开始正常电池充电。例如，控制器22可请求充电站24提供所需量的电流至电池充电器20用于给牵引电池18充电。随后算法结束。如果在操作48处得到的结果为否，则在操作52处生成提示车辆未与正确的充电站配对的信息。例如，控制器22可通过车辆的车辆区域网络广播指示其未正确地与从中接收能量的充电站通信的消息。控制器22可随后阻止任何进一步的电池充电行为直至解决该问题。
在此揭示的算法可以发送至处理设备或者通过其实施。该处理设备例如电池充电器20或控制器22，其可以包括可以以许多形式存在的任何现有的电子控制单元或专用电子控制单元，包括但不限于：永久地储存在非可写存储媒介(例如ROM设备)上的信息和存储在可写存储媒介(例如软盘，磁带，CD，RAM设备以及其他磁的、光的媒介)上的可变的信息。还可以在软件可执行对象中实施算法。可替代地，可以利用合适的硬件部件(例如专用集成电路(ASIC)、现场可编程逻辑门阵列(FPGA)、状态机、控制器等)或者其他硬件部件或硬件，软件和固件部件的结合部分地或者整体地实施算法。
尽管已经示出并描述了本发明的实施例，并不意图表示这些实施例示出并描述了本发明的所有可能的形式。在本说明书中的文字是说明性而非限制，且应当理解在不脱离本发明的精神以及范围下作出多种变形。
