本实用新型涉及电动汽车领域，特别涉及集成电气印刷电路板系统、为储能电池充电的补能系统、为电动汽车充电的充电系统以及用于移动充电车的电气柜。
背景技术
随着电动汽车保有量的增涨，电动汽车充电设施增涨速度不能满足其充电需求，另一方面由于电动汽车充电设施的地域分布不均匀，在无桩少桩的偏远地区用户体验较差。移动充电车可以随时随地给用户充电，将有利用解决前面所描述的矛盾。
移动充电车的电气柜受到体积的限制，需要将较为复杂的电气功能集成在体积较小的电气柜里面，这样电气柜里面的连线较多，空间狭小，可制造性和可靠性非常差。
以上公开于本实用新型背景部分的信息仅仅旨在增加对本实用新型的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
实用新型内容
鉴于此，本实用新型提供了一种基于PCB(印刷电路板)集成走线模块化设计，从而提高可制造性，提高可靠性与可维护性。本实用新型的基本思想是尽可能通过PCB内部走线来替代：大功率继电器、中间继电器、控制电路板相互的连接线。当这些相互之间的连接线利用PCB来走线后，整个电气系统接线将会大大简化，可提高电气系统的可制造性、可靠性、可维护性。

在上述集成电气印刷电路板系统中，所述一个或多个直插型引脚包括线圈供电引脚、常开触点引脚以及常闭触点引脚。

在现有的电气柜中存在大量的连线。在车载的环境下，连线端子容易发生松脱，其可靠性差，发生故障后难以检修。与现有方案相比，本实用新型通过将大量的走线集成于PCB板，从而降低生产成本，提高产品可靠性，提高产品的易维护性。
通过纳入本文的附图以及随后与附图一起用于说明本实用新型的某些原理的具体实施方式，本实用新型的方法和装置所具有的其它特征和优点将更为具体地变得清楚或得以阐明。
附图说明
图1是表示本实用新型的一个实施例的集成电气印刷电路板系统的结构示意图；
图2是表示本实用新型的一个实施例的补能系统的示意图；
图3是表示本实用新型的一个实施例的充电系统的示意图。
具体实施方式
以下说明描述了本实用新型的特定实施方式以教导本领域技术人员如何制造和使用本实用新型的最佳模式。为了教导实用新型原理，已简化或省略了一些常规方面。本领域技术人员应该理解源自这些实施方式的变型将落在本实用新型的范围内。本领域技术人员应该理解下述特征能够以各种方式接合以形成本实用新型的多个变型。由此，本实用新型并不局限于下述特定实施方式，而仅由权利要求和它们的等同物限定。
在本实用新型的上下文中，术语“PCB”、“印刷电路板”、“PCB板”或“PCB基板”具有相同的含义，除非另外指明。
功率继电器(power relay)是一种在输入量(或激励量)满足某些规定的条件时，能在一个或多个电器输出电路中产生跃变的一种器 件。可用于中性点直接接地系统，作为零序电流保护的方向元件。作为一个示例，大功率继电器是指当触点开路电压为直流300V时，触点额定负载电流为10A、15A、20A、25A、40A或更高的继电器。
中间继电器(intermediate relay)例如用于继电保护与自动控制系统中，以增加触点的数量及容量。它用于在控制电路中传递中间信号。中间继电器的结构和原理与交流接触器基本相同，与接触器的主要区别在于：接触器的主触头可以通过大电流，而中间继电器的触头只能通过小电流。
图1是表示本实用新型的一个实施例的集成电气印刷电路板系统的结构示意图。如图1所示，在一个集成电气印刷电路板系统中，包括PCB板、大功率继电器1、中间继电器2以及控制电路3。
参照图1，在一个实施例中，大功率继电器1具有动力线输入输出脚M、N，继电器线圈供电线e、f，辅助触点采样线两根c、d，电压采样线两根a、b，在继电器上a与M接一起，b与N接一起。其中动力线由于其通过的电流大，不适合用于PCB集成，而其他六根线电流较小，可以用PCB来集成走线。
为了实现大功率继电器1与PCB板的集成，考虑的方式是将大功率继电器1安装在PCB基板上，将a、b、c、d、e、f六根线就近引到PCB，对应PCB内部走线的1，2，3，4，5，6。
继续参照图1，在一个实施例中，中间继电器2具有线圈供电e、f，常开触点a、b以及常闭触点c、d。由于中间继电器具有直插型引脚，可以将中间继电器直接安装在PCB上。中间继电器通断电流较小，可以将其所有的走线集成，通过PCB来走线。这样不再需要中间继电器安装基座，可节省成本。另外，在移动充电车运行工况下，中间继电器直接插装并焊接在PCB上较插装在基座上具有更高的可靠性。
如图1所示，控制电路板卡3具有第一端子和第二端子。它可以直接集成于电气PCB板，也可以利用插针焊装在电气PCB板。
基于以上三种集成后，电气PCB板对外的接线将大量减少。
在一个具体的实现中，集成后的电气功能模块可分为三层:主功率 回路铜排层、电气PCB集成板层、大功率继电器安装金属板层。其中大功率继电器质量较大，需要安装在金属板上。与现有方案不同的是，上述实现将传统的错综复杂的连线做成印制电路板。例如，将小功率中间继电器直接焊装在PCB板上，其走线也同样PCB内部印制。这样无论是制造，还是后期维护检修都非常便捷。
图2是表示本实用新型的一个实施例的补能系统的示意图。该补能系统通过充电桩提供的电力，为电池包进行补能。在一个实施例中，如图2的虚线框所示，补能控制器、模拟量采样板、I/O板以及调试与诊断板集成于一块PCB板之上，其对外有对直流充电桩的接口，对电池包的接口，调试接口与诊断接口。
在图2中，补能控制器是一块带有MCU微控制器的板卡。模拟量采样板的功能是将大电压、大电流变成小信号经过电气PCB基板到补能控制器的MCU。I/O板是继电器的控制回路与继电器辅助触点回采信号板，I/O板的信号同样经过电气PCB集成板与补能控制器连接。调试与诊断板集成需要测量的模拟信号、I/O信号、通信网络接口信号的测试点，经过测试点可以很方便的调试与诊继。这块板卡在研发阶段、产品制造测试、产品质检、运营检修、故障诊断等过程中使用，将可以提高这样阶段的效率。
图3是表示本实用新型的一个实施例的充电系统的示意图。该充电系统通过一个或多个电池包提供的电力，为被服务车辆进行充电。在一个实施例中，如图3的虚线框所示，充电控制器、模拟量采样板、I/O板以及调试与诊断板集成于一块PCB板之上，其对外有对电池包的接口，对被服务车辆的接口，调试接口与诊断接口。
在图3中，充电控制器是一块带有MCU微控制器的板卡。模拟量采样板的功能是将大电压、大电流变成小信号经过电气PCB基板到充电控制器的MCU。I/O板是继电器的控制回路与继电器辅助触点回采信号板，I/O板的信号同样经过电气PCB集成板与充电控制器连接。调试与诊断板集成需要测量的模拟信号、I/O信号、通信网络接口信号的测试点，经过测试点可以很方便的调试与诊继。这块板卡在研发 阶段、产品制造测试、产品质检、运营检修、故障诊断等过程中使用，将可以提高这样阶段的效率。
在一个具体的实现中，上述补能系统和/或充电系统可应用于移动充电车的电气柜中。
综上，本实用新型通过将大量的走线集成于PCB板，从而降低生产成本，提高产品可靠性，提高产品的易维护性。
以上例子主要说明了本实用新型的集成电气印刷电路板系统、为储能电池充电的补能系统、为电动汽车充电的充电系统以及用于移动充电车的电气柜。尽管只对其中一些本实用新型的具体实施方式进行了描述，但是本领域普通技术人员应当了解，本实用新型可以在不偏离其主旨与范围内以许多其他的形式实施。因此，所展示的例子与实施方式被视为示意性的而非限制性的，在不脱离如所附各权利要求所定义的本实用新型精神及范围的情况下，本实用新型可能涵盖各种的修改与替换。
