请参阅图1，本发明还提供一种具体实施方式，以三个电池包为例进行进一步描述。
一种可更换电池的电气系统，包括：电气系统和D组合开关，所述电气系统包含有若干电池包。优选的，所述电池包为3个，分别为电池包1、电池包2和电池包3，所述电池包1、电池包2和电池包3之间独立设置。
所述D组合开关，适用于切换工作电池的机械或者电子开关，分若干档位，用于切换至任意档位将电气连接公共端与当前档位接线端，并断开其他档位接线端与公共端的连接。
所述电池包1、电池包2和电池包3可以运用于多种设备。
所述D组合开关上设置有用于显示电池包电量信息指示信号的电量显示装置和用于各电池包之间相互切换的档位开关；所述档位开关设置为若干档位， 在本实施例中优选为4个档位，分别为电池包1档位、电池包2档位、电池包3档位和OFF档位，OFF档位为关闭档位。
所述档位的数量随着电池包数量的变化而变化。
所述每个电池包中均包含有一个电池、一个动力开关和一个电池管理系统，所述每一个电池管理系统接收组合开关的输出信号，并与电量信息指示信号相结合，从而控制相应的动力开关是否闭合以提供电力输出。
一个电池、一个动力开关和一个电池管理系统三个部件组成一个电池包，它们可以被包装成一个独立的结构，同时也可以由若干个模块通过电气连接成为一个组合系统，若干个电池包组成一个电气系统。
电池包1中，包含为电池A1、动力开关B1和电池管理系统C1；
电池包2中，包含为电池A2、动力开关B2和电池管理系统C2；
电池包3中，包含为电池A3、动力开关B3和电池管理系统C3。
所述电池A1、电池A2和电池A3可以是铅酸电池、锂电池、镍氢电池等各种电池，在结构上不进行局限。
所述动力开关，可以是继电器、接触器等电子开关。
所述电池管理系统，管理一个电池单元。电池管理系统必须具备功能接受D组合开关的切换信号，且根据切换信号和电池自身状态控制相应的动力开关开通和关闭。
优选的，所述可更换电池的电气系统还包含有E安全开关，所述D组合开关与E安全开关连接形成一个回路，且通过回路中的组合开关输出电池管理系统低压电平信号。
所述电池包中的电池管理系统通过D组合开关和E安全开关连接的回路获得电池管理系统低压电平信号，且电池管理系统根据当前电量显示装置中的电 量状态决定是否闭合动开关以提供电力输出。
所述可更换电池的电气系统还包含有用于显示电池包故障状态的故障显示装置，所述故障显示装置优选为指示灯，所述指示灯具有颜色或是闪烁来显示电池包故障状态。
所述电气系统还包含有箱体，所述电池包均位于箱体内。所述箱体上进一步包含有箱盖或保险装置，所述箱盖或保险装置与所述安全开关控制连接。当箱盖打开或保险装置解除时安全开关断开，而箱盖关闭或者保险装置设置时闭合。
在另一种控制逻辑中，也可以当箱盖打开或保险装置解除时安全开关闭合，而箱盖关闭或者保险装置设置时断开。
在附图1中，所述E安全开关为当箱盖打开或保险装置解除时安全开关断开，而箱盖关闭或者保险装置设置时闭合。
操作时，安装入电池包1、电池包2和电池包3，并盖上箱盖或者保险装置，则E安全开关将随箱盖或者保险装置闭合。
将整机开关打开，电池包1、电池包2和电池包3的电池管理系统将通过外部或者内部电源工作。所述内部电源为电池A1、电池A2和电池A3，所述外部电源为位于外部且能提供电量的其他电源。
此时D组合开关上电池包1、电池包2、电池包3的背景指示信号或者相关指示面板等显示装置将显示相应电池包的电量信息。
若某电池指示信号为空，则表示所对应电池没有安装。
将D组合开关档位从OFF切换至电池包3，则电池包3的电池管理系统C3通过D组合开关和E安全开关连接的回路获得电池管理系统低压电平信号。此时电池管理系统C3将根据当前的电池状态决定是否闭合B3动力开关令电池 包3提供电力输出。
电池包的故障状态将通过声或光信息等故障显示装置提供给操作者，若为指示灯时，指示灯红色或者闪烁，此时D组合开关档位选择至故障电池包的电池管理系统将不会闭合B动力开关提供电力输出。
所述显示装置位于D组合开关的界面上，也可以由另外单独的界面进行控制显示。
当电池包3指示电量不足信号时，操作者将D组合开关档位切换至电池包2，此时电池包3的电池管理系统C3将失去D组合开关输入的电池管理系统低压电平，B3动力开关将会首先断开。接着电池包2将通过D组合开关和E安全开关构成的回路获得电池管理系统低压电平，此时如果电池包2的电池管理系统C2判断属于无故障状态，电池包2的电池管理系统C2将控制电池包2的B2动力开关闭合提供电力输出，从而实现电池包3到电池包2的切换。
如果所有电池或者其中若干电池的电量不足可以更换相应电池。
优选的，每一块电池都设计成适合人力或者简易工具搬运和拆卸的重量，且具备简易连接接口。
一般情况需要将D组合开关切换至OFF档位断开所有动力输出才能拆装更换电池。为了预防用户误操作，当用户带电更换或者拆卸电池包时，一旦打开箱盖或者机械保险装置时相关联的E安全开关将被断开，从而确保用户动手接触电池包时动力输出断开。
本发明可更换电池的电气系统的有益效果是：
1、提供一种可更换电池的电气系统,通过若干个独立的小电池构建的电气系统替代单个大型电池，降低电池的尺寸和重量,使使用者可以通过人力,或者简易 工具搬运和更换电池，提高换电效率并且能实现电池的通用性；
2、能够通过增加或者减少所安装的独立小电池的数量来对电池的总容量进行更改，从而能够最经济地匹配续航时间，根据预期的使用计划增减电池包数量，减少不必要的设备重量。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
