Description

对提供给充电电池的电力进行优化的发电系统
技术领域
本申请涉及发电系统，更特别地，涉及对提供给充电电池的电力进行优化的发电系统。
背景技术
发电系统用来向各种类型的耗电负载选择性地提供电力。一些发电系统包括用来启动发电系统内的引擎和/或发电机的电池。发电机故障的一个常见原因是启动电池没有提供足够的启动电流。
通常，此类传统发电系统中的电池或者由主电源充电，或者在主电源不可用时由次级电源（例如发电机）充电。这些类型的系统通常包括给每个电池充电的电池充电器。
现有发电系统中一些电池充电器的其中一个缺点是它们独立于发电系统的其余部件操作。由于大多数电池充电器通常连接到处于充满电状态的电池，所以，它们没有被使用到它们的全容量。因此，这些电池充电器大部分时间在以相当低的速率向它们各自的电池提供电流。
现有发电系统的另一个缺点是此类系统中的电池充电器不能一起工作以共享充电电流。因此，电池就会以更低的速率被充电。
因此，需要一种包括电池充电器的发电系统，这些电池充电器一起工作以便更有效地使用它们的容量。通过一起工作，这些电池充电器将会潜在地提高它们的充电速率。
附图说明
图1是图示说明示例性发电系统的功能框图，该示例性发电系统包括电池充电系统。
图2是相似于图1的功能框图，其中，发电系统包括外壳，其中，控制器、第一发电机和第一电池充电器都在该外壳内。
图3是相似于图1的功能框图，其中，发电系统包括多个电池充电器。
图4是相似于图1的功能框图，其中，发电系统包括多个电池充电器、多个发电机和多个电池。
具体实施方式
下文的描述和附图充分地阐述了具体的实施例，以使本领域技术人员能够实施它们。其它实施例可以包含结构的、逻辑的、有关电的、工艺方面的、以及其它的改变。一些实施例的部件和特征部分可以被包括在或代替其它实施例的部件和特征部分。权利要求中陈述的实施例涵盖这些权利要求的一切可用的等同方案。
图1是图示说明示例性发电系统10的功能框图。发电系统10包括第一发电机20和第一电池充电器40。在图1示出的示例性实施例中，第一电池充电器40适于给第一电池50和第二电池51充电。第一电池50和第二电池51均适于提供电力以启动第一发电机20。
发电系统10进一步包括控制器30，控制器30确定第一电池50和第二电池51中的每个的充电状态。基于第一电池50和第二电池51中的每个的充电状态，控制器30确定第一电池50和第二电池51中的哪一个从第一电池充电器40接收充电电流。
在一些实施例中，第一发电机20包括驱动交流发电机的内燃机。应当注意的是，在不偏离本发明范围的情况下，还可以考虑其它类型的发电机（即发电设备）。
考虑实施例，其中，第一电池充电器40适于从主电源11接收电力。作为一个例子，主电源11可以是公用电力。
在一些实施例中，控制器30是操作第一发电机20的发电机控制器。还考虑实施例，其中，控制器30操作第一电池充电器40。
应当注意的是，控制器30可以显示与第一电池50和第二电池51的充电电平相关的信息。作为一个例子，控制器30可以显示当前正在被第一电池充电器40用来给第一电池50和/或第二电池51充电的充电曲线（profile）（与第一电池充电器40所涉及的其它操作参数一起）。
作为另一个实例，控制器30可以显示在第一电池50和第二电池51的电池端子（battery terminals）（或电池的一些其它部分）处的电压、电流和/或温度。还作为又一个实例，控制器30可以显示与第一电池50、第二电池51、第一电池充电器40和/或第一发电机20的健康相关的故障、警告和/或其它状况。
在图1图示说明的示例性实施例中，第一电池充电器40、控制器30和第一发电机20没有位于同一外壳内。在图2图示说明的示例性实施例中，第一电池充电器40、控制器30和第一发电机20全部位于同一外壳60内。
在图3图示说明的示例性实施例中，控制器30和第一发电机20位于同一外壳60内。如图3所示，发电系统10可以进一步包括给第二电池51充电的第二电池充电器41。控制器30确定第一电池50和第二电池51中的哪一个从第一电池充电器40和第二电池充电器41中的至少一个接收充电电流。应当注意的是，尽管图3仅示出了两个电池充电器40、41，然而，发电系统10中可以包含任意数量的电池充电器。
在图3图示说明的示例性实施例中，第一电池充电器40可以连接到第二电池充电器41，使得第一电池充电器40和第二电池充电器41能够交换电力（以及潜在运行数据）。此外，第一电池充电器40可以连接到第二电池51，使得第二电池51从第一电池充电器40接收充电电流，第二电池充电器41可以连接到第一电池50，使得第一电池50从第二电池充电器41接收充电电流。
图4是功能框图，其中，发电系统10包括多个电池充电器40、41，多个发电机20、21，和多个电池50、51、52、53、54。在图4图示说明的示例性实施例中，一个或多个电池50、52提供电力以启动第一发电机20，一个或多个电池51、53、54提供电力以启动第二发电机21。
在图4图示说明的示例性实施例中，控制器30用作用于第一发电机20的发电机控制器，且发电系统10进一步包括额外的控制器31，控制器31是操作第二发电机21的发电机控制器。应当注意的是，控制器30和额外的控制器31中的任一个或两个可以确定多个电池50、51、52、53、54中的哪一个从第一电池充电器40和/或第二电池充电器41中的至少一个接收充电电流。
应当注意的是，发电系统10中所包含的任何电池充电器和控制器可以通过连接控制器和/或电池充电器的通信总线交换数据。此外，电池充电器和/或控制器可以无线交换数据。
再次参考图1，电力管理系统10进一步包括通过网络（例如，因特网I、本地网络和/或无线形式的通信方式）连接到控制器30的服务器70。在一些实施例中，服务器70向控制器30提供关于第一电池50和第二电池51中的哪一个从第一电池充电器40接收充电电流的命令。
应当注意的是，服务器70可以被包含在图2-图4示出的其它实施例中，使得服务器70向一个或多个控制器30、31提供关于多个电池50、51、52、53、54中的哪一个从第一电池充电器40和/或第二电池充电器41中的至少一个接收充电电流的命令。此外，服务器70可以与第一电池充电器40和第二电池充电器41中的至少一个直接通信。
提供摘要以符合37C.F.R.部分1.72（b）的规定，要求摘要能使读者确定技术公开的本质和主旨。可以理解，摘要不用来限制或解释权利要求的范围或含义。权利要求在此被并入详细的描述中，且每项权利要求本身是单独的实施例。
