Description

用于给高压车载电源的高压电池或低压车载电源的低压电池 充电的车载充电器和方法
本发明涉及一种用于给高压车载电源的高压电池或低压车载电源的低压电池充电的车载充电器。车载充电器包括用于给交流电压滤波的电源滤波器和用于调整输入电流的功率因数校正滤波器。车载充电器还包括第一直流电压变换器，其具有包括初级侧和次级侧的变压器，其中，通过第一直流电压变换器的次级侧的第一电路能够借助于第一直流电压变换器给高压电池供以第一直流电压。车载充电器还包括直流电压滤波器。本发明还涉及一种用于给高压车载电源的高压电池或低压车载电源的低压电池充电的方法。
电动车或插电式车辆具备以下可能，即，高压电池可在充电桩或家用接头处利用车载充电器以单相或多相方式来充电。高压电池给其它高压部件例如像电驱动系统、空调、加热器或信息娱乐系统供电。另外，存在直流电压变换器，其由高压电池的高电压产生低压电压并且给12伏车载电源供电。
US 2010/0231169 A1公开一种机动车，其包括电路且能够与电网相连。此外，机动车包括电连接至该电路的电驱动系统和与电驱动系统电连接的变流模块。借助蓄能单元，换能器与模块电连接。
在此出现的缺点是高压电池和/或低压电池的充电操作需要许多电路和元件。
本发明的任务是提供一种车载充电器和一种方法，借此可以在功能上扩展车载充电器，从而可以利用协同作用。
该任务通过根据独立权利要求的车载充电器和方法完成。有意义的改进方案来自从属权利要求。
本发明的一个方面涉及一种用于给高压车载电源的高压电池或低压车载电源的低压电池充电的车载充电器。车载充电器具有用于对交流电压进行滤波的电源滤波器和用于调整输入电流的功率因数校正滤波器。借助车载充电器的具有包括初级侧和次级侧的变压器的第一直流电压变换器，高压电池可通过第一直流电压变换器的次级侧的第一电路被供以第一直流电压。另外，车载充电器包括直流电压滤波器。利用第一直流电压变换器的次级侧的第二电路，可以给低压电池供以第二直流电压。如此设计控制单元，即，能够启用第一直流电压变换器的次级侧的第一电路或第二电路。通过对第一直流电压变换器的次级侧进行划分，可以利用协同作用。通过使用第一直流电压变换器来给高压电池和低压电池供电，尤其可以在唯一的部件或电路布置中使用车载充电器的和直流电压变换器的功能。在此，尤其是车载充电器担负直流电压变换器的功能。由此尤其可以节省构件、重量、体积和成本。通过在唯一的共同壳体上使用这两个不同部件的两个功能，尤其是可以放弃附加的冷却概念，因为两个功能可以利用在共同壳体中的共同冷却概念来冷却。尤其是，因为在一壳体上使用这两个功能，接口、高压电线以及低压电线的数量减少。尤其是可以由此在高压电池或低压电池的充电操作中保持低的损失功率，因为不需要多个电子元件或电路。
尤其可以利用车载充电器来以单相或三相方式给该高压电池充电。尤其是首先用作为功率级第一部分的电源滤波器对输入侧的交流电压进行滤波。在所述滤波之后，可以借助功率因数校正滤波器(PFC)使输入电流适配于尽量正弦形的曲线。尤其是输入电流应该与输入侧电源电压是同相的。由此，例如回扩到电网中的谐波减少并且功率因数由此改善。另外，功率因数校正滤波器的PFC级产生可控输出电压，借此能够给后置/下游的电压变换器供电。在功率因数校正滤波器之后紧接有第一直流电压变换器，其用于电流隔离并且产生输出电压，该输出电压的特性恰好符合高压电池的充电曲线。在将整流后的输入电压提供给高压电池之前，借助直流电压滤波器对整流后的输入电压进行滤波。
尤其是，车载充电器可以被用来给电动车或混动车的高压车载电源的高压电池或者低压车载电源的低压电池充电。第一直流电压变换器尤其是具有变压器，变压器被分为初级侧和次级侧。在此，初级侧例如包括初级线圈，次级侧包括次级线圈。第一直流电压变换器的次级侧尤其被分为两个部分或者说两个单独的次级线圈。在此，次级侧的次级线圈被分为第一次级线圈和第二次级线圈。当高压电池在充电过程中应被充电时，借助控制单元来接通并启用次级侧的第一次级线圈，因此高压电池被供以第一直流电压或者可被充以第一直流电压。尤其是，控制单元将充电操作节拍化并且使第一直流电压适配于高压电池所要求的充电电压。尤其在次级侧的第一次级线圈启用时，第二次级线圈被停用。
例如在电动车或混动车的行驶操作时，次级侧的第二次级线圈被启用且同时第一次级线圈被停用。在此，借助第一直流电压变换器的第二次级线圈给低压车载电源或低压电池供以第二直流电压。例如低压车载电源可以是12伏车载电源。
本发明的另一方面涉及一种用于高压车载电源的高压电池或低压车载电源的低压电池的充电方法，其中，高压电池以第一直流电压被充电，第一直流电压利用直流电压变换器的变压器的次级侧的第一电路来产生。低压电池以第二直流电压被充电，第二直流电压利用直流电压变换器的次级侧的第二电路来产生，在这里，要监测只给低压电池充电或只给高压电池充电。
尤其是，电动车或混动车的高压电池或低压电池被充电。
尤其是，第一直流电压通过对车载充电器的输入侧交流电压进行变换而转换得来。直流电压变换器由次级侧和初级侧构成并且包括变压器，变压器具有初级线圈和次级线圈。直流电压变换器的次级侧被分为第一次级线圈和第二次级线圈。在次级侧的第一电路中，第一次级线圈被切换到启用，在这里，高压车载电源的高压电池由此可被供以第一直流电压或被充以第一直流电压。尤其是，高压电池在电动车或混动车的充电操作期间被充电。一旦低压电池应被充电，则次级侧的第一次级线圈可以停用，而次级侧的第二次级线圈启用，从而低压电池可以借助于第二直流电压被充电。尤其是，低压电池可以是12伏车载电源的电池。尤其是要监测总是只能给低压电池充电或只能给高压电池充电。尤其是，低压电池通过高压电池的电池电压被充电。
从以下对优选实施例的说明中以及结合图得到本发明的其它优点、特征和细节。以上在说明书中提到的特征和特征组合以及以下在附图说明中提到的和/或在图中被单独示出的特征和特征组合不仅在各自所指明的组合中、也在其它组合中或单独地可使用，而没有超出本发明的范围。在此，以下的图示出了：
图1示出车载充电器的示意图；
图2示出用于给高压电池充电的示意性电路布置；
图3示出用于给低压电池充电的示意性电路布置。
在所述图中，功能相同的零部件带有相同的附图标记。
图1示出用于给高压车载电源的高压电池2或低压车载电源的低压电池3充电的车载充电器1。车载充电器1例如可以被用于高压电池2的单相或三相充电过程。尤其是可以利用车载充电器来给电动车或混动车的高压电池2或低压电池3充电。车载充电器1在输入侧具有电源滤波器4。利用电源滤波器4可以对输入侧的加载于车载充电器1输入端的交流电压UAC进行滤波。在交流电压UAC借助电源滤波器4被滤波之后，后置有/在下游连接有功率因数校正滤波器5，借此可以将交流电压UAC的输入电流置于正弦走向，尤其是与交流电压UAC同相。尤其是利用功率因数校正滤波器5产生用于后置的电压变换器6的可控输出电压。功率因数校正滤波器5包括能够对后置的第一电压变换器6进行预充电的预充电电路7。功率因数校正滤波器5的预充电电路7具有第一电阻R1和预充电开关SL。
第一直流电压变换器6包括变压器8(见图2)。变压器8被分为初级侧9和次级侧10。初级侧9尤其包括初级线圈11，次级侧10被分为第一次级线圈12和第二次级线圈13。
第一直流电压变换器6尤其是电流隔离的，并且提供第一直流电压U1。第一直流电压U1随后借助于直流电压滤波器14被滤波，并且被提供给高压电池2。
在高压电池2的上游可以设有预充电电路15，借此能够由第一直流电压U1给高压电池2充电。尤其是，高压电池2可以通过第二电阻R2被预充电。在此，预充电开关SV被接合。同样可以想到，能够以第一直流电压U1给中间电路电容器CK充电。在此，预充电开关SV和第一主接触器HS1和第二主接触器HS2被断开。当主接触器HS1和HS2二者都被接合时，高压电池2可以通过中间电路电容器CK被充电。由此尤其可以放弃在充电器和高压电池2中的预充电电路。
例如车载充电器1可设计用于在230V和16A时以高达3.7kW进行充电操作。
图2示出在高压电池2充电时的车载充电器1的示意性布置。尤其是，高压电池2以第一直流电压U1被充电，第一直流电压利用第一直流电压变换器6的变压器8的次级侧10的第一电路来产生。尤其是，在第一电路中，次级侧10的第一次级线圈12启用，而第二次级线圈13停用。次级侧10的次级线圈12和第二次级线圈13的启用尤其是通过车载充电器1的控制单元16来进行的。尤其是，控制单元16用于启用第一直流电压变换器6的次级侧10的第一电路或第二电路。可以总是仅给高压电池3或者低压电池2供电。在以第一直流电压U1给高压电池2充电时，开关S1、S2、S4被断开并且开关S3被接合。尤其是控制单元16将充电操作同步到高压电池2所要求的充电电压。开关S1-S4可以是机械开关或半导体开关。机械开关和/或半导体开关的使用取决于对车辆的具体安全要求。
尤其是高压电池2的充电是在电动车的充电操作中进行的。因为在高压电池2的充电操作期间所述低压电池3或第二次级线圈13停用，故借助第二直流电压变换器17提供第三直流电压U3，进而给低压车载电源或低压电池3供电。例如，第二直流电压变换器17可以被集成到高压电池3中。尤其是，第二直流电压变换器17用于给车辆的安全相关部件供电或保证紧急呼叫供电。尤其是应该随时可以在事故或危险情况下发出紧急呼叫。这需要最小电压。尤其可以用第二直流电压变换器17在高压电源电网或高压电池2关闭或断开的情况下保证应急部件的供电。尤其可以提供12伏的电压。第二直流电压变换器17例如可以是微型变换器。
图3示出借助车载充电器1的低压电池3充电过程。尤其是低压电池3在电动车或混动车的行驶中充电。在低压车载电源的充电操作中，开关S1、S2、S4被接合且开关S3被断开。低压车载电源或低压电池3借助直流电压变换器6的第二电路来充电。在第二电路中，次级侧10的第一次级线圈12停用，次级侧10的第二次级线圈13启用。所述启用或停用通过控制单元16来进行。借助启用的第二次级线圈13，将高压电池2的电池电压UBat转换为第二直流电压U2。尤其是第二直流电压U2的电压水平为12伏。尤其是在低压电池3的充电过程中该控制单元16被按节拍驱动，从而尤其可以给12伏车载电源供电。第一直流电压变换器6例如可被用于借助低压电池3给高压车载电源预充电。尤其在低压电池3有效充电时，无法给该高压电池2充电。
尤其是，车载充电器1包括车载充电器和DC-DC变换器二者的功能，因为车载充电器1利用两个功能的协同作用。尤其是，车载充电器的功能和DC-DC变换器的功能被整合在共同壳体内或呈车载充电器1形式的组成部件中。
