Description

家庭用光储式离网充电桩
技术领域
本发明涉及的是离网充电桩技术领域，具体的说是一种家庭用光储式离网充电桩。
背景技术
随着我国经济的持续发展和国际煤炭、石油等资源的紧缺，我国能源发展将面临供需缺口大、石油后备资源不足、以煤为主的能源结构带来的严重环境污染和气候变暖等一系列问题。而太阳能是地球永恒的能源，其照射到地球上的能量要比人类消耗的能量大6000倍，具有广阔的利用前景。因此，应用太阳能电池组件发电从而满足家庭直流负载(电动自行车、电动三轮车、电动汽车以及其直流负载充电的要求)用电，可以很好的解决环境污染问题和节能减。
目前，以电网作为电能的电动汽车充电桩存在着两个方面的缺点：一是充电桩的电能来源依靠是电网，而电网电能大多来自火电厂的发电，并没有从源头上解决污染问题；二是充电桩的大量使用会产生谐波，给电网的稳定运行带来一定程度的危害，影响了电能的质量，同时也加重了电网的承受能力。随着城市家庭住宅的高层化以及农村家庭的城镇化，城市楼房没有自己的车库，从而给每个家庭的电动自行车、电动三轮车以及电动汽车充电带来困难，既没有专门的空间也没有市电可利用，同时每天搬动电池到楼上充电也是费力费电的事情。
发明内容
本发明的目的在于针对现有技术的缺陷和不足，提供一种结构简单，设计合理、使用方便的家庭用光储式离网充电桩，利用光伏阵列，将太阳能转化成电能作为家庭直流负载用电的主要能量来源，具有可持续发展和绿色环保的双重意义。
为实现上述目的，本发明采用的技术方案是：一种家庭用光储式离网充电桩，包含光伏组件、直流变换模块、直流母线、直流变交流模块、交流负载、铅碳电池、蓄电池充放电模块、费用计量模块、控制器模块、电源模块和液晶显示屏，所述光伏组件的输出端与直流变换模块的输入端连接，所述直流变换模块的输出端与直流母线连接，所述直流母线与直流变交流模块的输入端连接，所述直流变交流模块的输出端于交流负载的输入端连接，所述铅碳电池与蓄电池充放电模块交互式连接，所述蓄电池充放电模块与直流母线交互式连接，所述电源模块的输出端与控制器模块的输入端连接，所述控制器模块的输出端与液晶显示屏的输入端连接，所述控制器模块均与直流变换模块、蓄电池充放电模块、直流变交流模块、费用计量模块连接。
采用上述结构后，本发明的有益效果为：
1、节约电能，减少对环境的污染，具有可持续发展能源和绿色环保双重意义。
2、减轻搬运电池上下楼的劳动量，充电方便；
3、利用铅碳蓄电池作为储能系统，保证没有光照时充电桩充电的稳定性，和一般蓄电池相比较，使用寿命长、价格降低。
4、配备能源管理系统，具备能源管理和策略调度的功能。
5、产品具有较强的实用性，可以为电动自行车、电动三轮车和电动汽车充电。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施方式，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施方式仅用以解释本发明，并不用于限定本发明。
一种家庭用光储式离网充电桩，包含光伏组件、直流变换模块、直流母线、直流变交流模块、交流负载、铅碳电池、蓄电池充放电模块、费用计量模块、控制器模块、电源模块和液晶显示屏，所述光伏组件的输出端与直流变换模块的输入端连接，所述直流变换模块的输出端与直流母线连接，所述直流母线与直流变交流模块的输入端连接，所述直流变交流模块的输出端于交流负载的输入端连接，所述铅碳电池与蓄电池充放电模块交互式连接，所述蓄电池充放电模块与直流母线交互式连接，所述电源模块的输出端与控制器模块的输入端连接，所述控制器模块的输出端与液晶显示屏的输入端连接，所述控制器模块均与直流变换模块、蓄电池充放电模块、直流变交流模块、费用计量模块连接。
本具体实施方式中采用如下设计：
1、光伏阵列系统设计：其包括太阳能光伏阵列板，DC/DC转换电路。首先对光伏阵列的工作原理作简要介绍，并选用合适高效的整流电流，使得系统稳定运行，能高效产生电能。
2、直流母线的选型和储能系统的设计：对不同种类蓄电池及其特性进行分类介绍，分析各种充电策略优缺点和适用范围。
3、充电桩系统设计：本设计采用直流充电桩进行充电，其包括DC/DC转换电路和充电电路。首先对各种充电电路的设计进行比较和分析，以及配电系统的设计和容量优化配置和可靠性分析，最终通过人机交互来实现应用。
4、铅碳电池的充放电管理(BMS)：按照选用电池的不同型号，采用不同的充放电管理，从而提高电池的充放电效率和使用寿命
5、软件设计：软件设计主要包括光伏阵列的MPPT算法实现和充电桩的充电计费策略和通信设计：
6、能量管理系统(EMS)：为了提高系统效率，实现节能减排，对太阳能电池组件、蓄电池以及负载的电能流向实现管理，实现功率平衡，尽量发挥太阳能电池组件的功能。

本具体实施方式依据直流母线为依托，光伏阵列把太阳能转化为电能通过整流变换输到直流母线上，充电桩系统通过从直流母线上获取所需要的电能，来满足用户需求，过剩的电能通过直流母线传给储能电池系统，以供产能不足时的后备使用。为了使光伏最大能源的获得和充电桩的稳定运行，使得整个系统安全可靠。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
