Description

用于准备为车辆供电的方法
技术领域
本发明涉及一种用于通过提供至少一个供电电压的供电设备向具有供电装置的车辆、尤其是电动车或者混合动力车准备供给电能的方法，该车辆与该供电设备设计成相互分开的并且借助于在车辆的供电装置与供电设备之间的插接接触可脱开地相互电连接。
背景技术
为了可以快速地给电动车或混合动力车供给电能，例如为了可以快速地给车辆的蓄能器、例如蓄电池再充电，存在快速供电设备，所谓的充电装置或者快速充电装置，它们大多设计成充电桩。
例如，常见的DC快速充电桩具有0至1500V DC的输出电压范围，也就是说，它们可以提供0至1500V的充电电压作为直流电压供使用。为了给电动车的蓄电池充电，使电动车与DC快速充电桩例如通过插接接触相互电连接。图1以示意的方式示出了这种电连接或布置。
DC快速充电桩1具有插头2，该插头与AC/DC转换器和PLC部件4连接。AC/DC转换器3又与电网接头N连接。
电动车5包括与插头2共同作用的充电插座6，它通过HV线路HV+和HV-(HV＝高压)与HV插接装置7连接。HV插接装置7通过保险装置K1和K2可与要被充电的电池8连接。此外，充电插座6与车辆的PLC部件9连接。作为另一硬件线路，在车辆方面存在所谓的PRX线路10或邻近线路(Proximity-Leitung)。
为了给电池8充电，电动车5在DC充电的初始阶段通过DC快速充电桩1的电力线路通信(PLC＝Power Line Communication，电力线路通信)通知车辆5的电池8最大允许的充电电压和理论电压、即在充电过程之后要达到的电压值。于是将DC快速充电桩1相应调整到用于车辆5的期望充电电压。车辆5借助于电压计V1识别或测量施加的充电电压并且当施加的电压相当于所要求的充电电压时，接通车辆方面的保险装置K1和K2。
充电桩或供电设备与车辆之间通过PLC通信的缺点是，通信没有安全相关地分级。因此，由于在充电桩与车辆之间通信时的错误或者由于充电桩本身中的故障可能导致，充电桩输出或者说在车辆上施加过高的充电电压、例如1500V，尽管要求较低的充电电压。
因此，目前出于安全的原因必需以1500V电压设计参与电池8充电的车辆5部件。但是，一般在车辆中使用的部件没有这样的耐压性。对于电池8典型的电压范围在直到500V。车辆方面的HV线路HV+和HV-一般针对直到600V的电压范围设计。车辆方面的保险装置K1和K2以及车辆方面的HV插接装置7一般针对直到850V的电压范围设计。
由于设计直到1500V的上述部件不仅增加车辆的成本和重量，而且在车辆中对于相应体积庞大的部件也需要相应的结构空间。
在DE 102009025303A1中描述了一种用于与电动车通信的方法，包括在控制导体上产生第一预定直流电压水平，通过检测在控制导体上的第二预定直流电压水平识别存在与电动车的电连接，在控制导体上发出激活信号，检测在控制导体上的车辆识别信号并且在功率导体上释放电流供给。
由US 5,548,200已知一种充电站以及一种用于给车辆的电池充电的方法，其中，与何种类型的充电控制器位于车辆中和附设于电动车电池无关地，可以实现到电动车电池的充电电能输送。
发明内容
本发明的目的在于，这样地提供开头所述类型的方法，使得车辆的供电装置与电的供电设备之间的通信得以改进。
按照本发明，该目的通过一种用于通过提供至少一个供电电压的供电设备为具有供电装置的车辆准备供给电能的方法得以实现，该车辆和供电设备设计成相互分开的并且借助于车辆的供电装置与供电设备之间的插接接触可脱开地相互电连接，其中，在车辆的供电装置与供电设备之间电连接以后准备供给电能过程中，供电设备通过由插接接触闭合的线路形式的第一通信路径获取表征车辆的电压等级的特定电压，并且基于获取的特定电压识别车辆的电压等级，并且其中，供电设备通过电力线路通信形式的第二通信路径将获取的电压等级反馈到车辆的供电装置上。
按照本发明不再只是通过供电设备与车辆的供电装置之间的通信路径实现通信，而是除了电力线路通信以外还提供硬件线路形式的第二或者说备选的通信路径。通过这种方式可以确保，通过在两种不同通信路径上的双向通信以所需的供电电压给车辆供电，或者说必要时在结论/指示冲突时中断供电过程。这对于车辆构造、尤其是车辆供电装置的部件意味着，这些部件无需过尺寸设计，以便在错误施加供电电压时的情况下防止损伤部件。
本发明的扩展结构规定，车辆的供电装置借助于电力线路通信向供电设备传输为车辆供给电能而允许施加的最大供电电压值，所述供电设备将对应于识别电压等级的供电电压最大值与传输的、为车辆供给电能允许施加的最大供电电压值进行比较，并且其中，如果对应于识别的电压等级的供电电压最大值小于或等于传输的、为车辆供给电能允许施加的最大供电电压值，供电设备在供给电能的准备阶段中允许继续供电过程。通过这种方式已经在供电设备一侧上防止施加过高的供电电压。
按照本发明的另一扩展结构，为了给车辆的电蓄能器充电而进行电能供给。但是电能供给也可以设计用于向车辆的其它部件供给电能，例如车辆内部空间的空调装置。
按照本发明的一种变型，在车辆方面通过车辆的供电装置的电压源产生表征车辆的电压等级的电压。
备选地，按照本发明的另一变型，通过在具有电阻的分压器上的电压降产生表征车辆的电压等级的特定电压。
按照本发明的一个实施例，通过车辆的供电装置的邻近线路/近中心的线路形成车辆方面的线路区段。该邻近线路在车辆的供电装置与供电设备连接时与供电设备的连接线路接触，优选一电压计与该连接线路连接。
按照本发明的另一变型，为了执行本方法，不仅车辆的供电装置而且供电设备分别具有控制装置，该控制装置是程序控制的计算装置。
本发明的一种扩展结构规定，供电设备可以提供多个不一样高的充电电压供使用，这些充电电压可以是直流电压和/或交流电压。
附图说明
在示意性的附图中示出了本发明的实施例。附图示出：
图1按照现有技术的布置结构；
图2用于执行按照本发明方法的布置结构。
具体实施方式
在图2中所示的布置结构的基本结构对应于在图1中所示的布置的基本结构，因此相同或结构相同的部件配有相同的附图标记。
在本发明的本实施例情况下，示例地借助于电动车5的蓄能器8的DC充电描述按照本发明的方法。
供电设备1或充电装置1设计成充电桩1的形式、尤其由DC快速充电桩1，它在本发明的本实施例的情况下可以提供三种直流电压或充电电压，最大600V的U1，最大1000V的U2，最大1500V的U3，由此可以确定三个电压等级或者说三个车辆等级，该车辆的蓄能器可以通过充电桩1充电。
与图1所示的布置结构不同，图2的充电桩1具有附加的连接线路20以及与连接线路20连接的电压计V2。此外，充电桩1具有控制装置21，用于在充电桩侧控制充电过程，该控制装置与充电桩1的上述部件共同作用或者说驱控这些部件。
在此，供电装置或者说在本发明的本实施例情况下电动车5的充电装置包括充电插座6、HV线路HV+、HV-、HV插接装置7、电压计V1、保险装置K1、K2、电池8形式的蓄能器、PLC部件9、PRX线路10以及电阻R1,R4a,R4b和R4c。此外，为了解释按照本发明的方法所述的部件只示例性地理解。因此保险装置K1和K2例如也可以通过其它隔离装置构成。
在本发明的本实施例情况下，对电阻R4a借助于开关S4和S5并联电阻R4b和R4c。此外，电动车5的充电装置包括控制装置30，用于在车辆侧控制充电过程，该控制装置与车辆5的充电装置的上述部件共同作用或者说控制这些部件。
为了准备给电池8充电，使车辆5或者说车辆5的充电装置与充电桩1通过充电插座6和插头2机械且电地相互连接，由此获得在图2中所示的电接触。
通过PRX线路10和连接线路20(它们形成第一通信路径)，在充电过程的初始阶段将车辆5的电压等级由车辆5通知充电桩1或者说充电桩1的控制装置21，即，车辆是否属于从属于U1的电压等级、U2的电压等级或者U3的电压等级。这样实现这一点，在通过规定选择的电阻R1，R2和R4a构成的分压器上施加特定电压。在车辆5中施加在分压器上的或者说降低的特定电压本身可以为了诊断目的通过控制装置30评估。
在充电桩1中通过控制装置21驱控地通过电压计V2评估施加在分压器上的或者说降低的特定电压。以获取的特定电压为基础，充电桩1的控制装置21将用于给车辆5的电池8充电的规定充电电压限制到特定的充电电压值，具体是限制到传输的车辆5的电压等级的最大充电电压值，在此限制到充电电压U1。
在第二通信路径、也就是PLC(Power Line Communication)上，充电桩1借助于PLC部件4并且通过充电桩侧的控制装置21控制地将通过V2获取的车辆5电压等级反馈到车辆5或者车辆5的PLC部件9，并由此传回到车辆侧的控制装置30。
因此，在本实施例情况下车辆侧的控制装置30通过PLC将为给电池8充电允许施加到车辆5的充电装置上最大电压传输到充电桩1或者充电桩侧的控制装置21。
充电桩1或者说充电桩侧的控制装置21将在充电桩1上以通知的车辆5的电压等级为基础设定的特定的充电电压值与通过PLC从车辆5传输到充电桩1的、用于给车辆5的电池8充电的最大允许充电电压值进行比较。如果在充电桩1上设定的特定充电电压值小于或者等于通过PLC传输的最大允许充电电压的电压值，则充电桩1或者说充电桩侧的控制装置21在充电过程的初始阶段中释放以设定的特定充电电压值对车辆5的电池8的充电。
但是，如果在充电桩1上设定的特定充电电压值大于通过PLC传输的最大允许充电电压的电压值，则充电桩1或者充电桩侧的控制装置21阻止对车辆5的电池8充电。
很明确，在所述方法的过程中，首先以在通过电阻R1，R2和R4a形成的分压器上降低的特定电压为基础通知充电桩1车辆5的电压等级。为了识别车辆的电压等级也按规定选择或者要选择电阻R1，R2和R4a的值。尤其根据相应车辆的电压等级对于不同电压等级的车辆区别电阻R4a的值。
在本发明的本实施例情况下，如上所述，通过有选择地操纵开关S4和S5能够并联电阻R4a,R4b和R4c。通过这种方式可以与充电桩1相结合检查，充电桩1实际上在总电阻改变时是否识别不同的电压等级并且相应地反馈到车辆。通过有选择地操纵开关S4和S5也可以通过询问安全性的形式检查充电桩的功能性。在车辆侧通过控制装置30实现操纵开关S4和S5。
这样选择电阻值，充电桩1
–当开关S4和S5断开时，必需识别最大至600V的电压等级U1，
–当开关S4闭合而开关S5断开时，必需识别最大至1000V的电压等级U2，并且
–当开关S4和S5闭合时，必需识别最大至1500V的电压等级U3。
通过电阻的其它并联电路也可以表征或识别车辆的其它电压等级。但是因为车辆的电压等级不变，也可以分别在车辆中存在具有确定电阻值的确定电阻R4a，借助于该电阻获取车辆电压等级。
备选地，可以在一个或多个电阻位置上在车辆侧分别设有用于识别车辆的电压等级的电压源，该电压源具有特定电压。
本发明在上面描述了给车辆的电池充电的过程。但是，按照本发明的方法不局限于蓄能器、例如电池或蓄电池的充电过程。而是，按照本发明的方法也可以用于为车辆的其它耗电器或者部件准备提供电能。例如本方法可以用于为车辆的空调装置准备提供电能。
