Description
技术领域:
本发明涉及太阳能发电及电动汽车无线充电新能源应用技术领域,具体涉及一种基于太阳能发电的无线充电立体停车库***。
背景技术:
无线能量传输技术是一项全新的电能传输技术。利用这项技术可以解决许多有线供电中存在的问题,如灵活方便性较差、导体接触部分容易磨损、容易产生火花、供电线外露带来的安全隐患等问题。
基于谐振式磁耦合方案原理的无线充电***,用于电动汽车无线充电。可以弥补传统接触式充电方式的各种缺陷,电动汽车无线充电技术在近几年得以快速发展,此技术实现充电器和电动汽车二者之间没有导线连接,避免充电过程中的触电危险,更重要的是这项技术改变以往通过增加电池比能量的方式来增加汽车续驶里程的措施,改为通过使用小容量、长寿命的电池的频繁充电来提高汽车续航能力;同时无线充电技术还可以实现汽车充电的自动化,提高电动汽车工作效率。
目前市面上还没有能实现无线充电的路边立体停车库,电动车充电一般是通过市电通过来充电,这易造成市电紧张,充电成本偏高,特别是用电高峰期间给电动车充电,易造成用电小区断电的情况,同时充电成本较高,给人们的生活带来了不便。
发明内容:
本发明的目的就是针对现有技术之不足,而提供基于太阳能发电的无线充电立体停车库,它利用太阳能和市电给路边立体停车库中的电动车进行无线充电,降低了充电成本,方便了人们的生活。
本发明的技术解决措施如下:
基于太阳能发电的无线充电立体停车库,包括立体停车库1,在立体停车库库顶固定有太阳能光伏板2,在立体停车库1的横梁板3上固定有车库充电装置4;
车库充电装置4的结构是:箱体41上固定有横向伺服电机42,滑板43的下部安装有滑板行走轮44,横向伺服电机42的转轴上固定有横向丝杆45,滑板43上固定有横向螺母46,横向丝杆45与横向螺母46螺接在一起;车库磁耦合线圈5的磁芯51为E字型,磁芯51的下端固定在塑胶托架47上,塑胶托架47下部安装有线圈行走轮48,线圈行走轮48置于滑板43的导槽431中;滑板43上固定有防尘罩49,磁芯51位于防尘罩49中,纵向伺服电机4a固定在滑板43上,纵向伺服电机4a的转轴上固定有纵向丝杆4b,纵向丝杆4b与纵向螺母4c螺接在一起,纵向螺母4c固定在磁芯51上;
太阳能光伏板2和市电6给双向储能逆变器7供电,双向储能逆变器7给车库磁耦合线圈5供电,电动车8上固定有车载磁耦合线圈9、充放电控制电路10和电动车蓄电池81,车库磁耦合线圈5的磁芯51与车载磁耦合线圈9的磁芯结构相同且相对,车载磁耦合线圈9通过充放电控制电路10给电动车蓄电池81充电;
电动车蓄电池81上电连接有蓄电池检测器11,蓄电池检测器11的检测信号输送给MCU控制单元12,MCU控制单元12控制双向储能逆变器7是否给车库磁耦合线圈5供电;
光电探头13固定在箱体41上,光电探头13检测电动车8的位置信号,光电探头13的位置信号输送给MCU控制单元12,MCU控制单元12根据光电探头13的位置信号控制横向伺服电机42和纵向伺服电机4a工作。
所述光电探头13有四个,分别固定在箱体41的四个角部。
本发明的有益效果在于:
1、现有立体停车库的太阳能发电后都直接并网,但是太阳能并网的利用效率较低;本发明太阳能发电后直接为电动汽车提供无线充电,能让立体停车库的太阳能电能充分有效利用。本发明只有当太阳能电能给电动车充电电能不足时,才启用市电给电动车充电。
2、它能自动检测电动车的位置,根据电动车的位置调整车库磁耦合线圈的位置,让车库磁耦合线圈与车载磁耦合线圈能正对实现充电,从而提高充电效率。
3、它通过蓄电池检测器检测电动车蓄电池的电量电压情况,及时由MCU控制单元控制双向储能逆变器是否停止充电。
附图说明:
图1为本发明的结构示意图;
图2为本发明的电路方框原理图;
图3为车库充电装置与车载磁耦合线圈相对时的结构示意图;
图中:1、立体停车库;2、太阳能光伏板;3、横梁板;4、车库充电装置;5、车库磁耦合线圈;6、市电;7、双向储能逆变器;8、电动车;9、车载磁耦合线圈;10、充放电控制电路;11、蓄电池检测器;12、MCU控制单元;13、光电探头。
具体实施方式:
实施例:见图1至3所示,基于太阳能发电的无线充电立体停车库,包括立体停车库1,在立体停车库库顶固定有太阳能光伏板2,在立体停车库1的横梁板3上固定有车库充电装置4;
车库充电装置4的结构是:箱体41上固定有横向伺服电机42,滑板43的下部安装有滑板行走轮44,横向伺服电机42的转轴上固定有横向丝杆45,滑板43上固定有横向螺母46,横向丝杆45与横向螺母46螺接在一起;车库磁耦合线圈5的磁芯51为E字型,磁芯51的下端固定在塑胶托架47上,塑胶托架47下部安装有线圈行走轮48,线圈行走轮48置于滑板43的导槽431中;滑板43上固定有防尘罩49,磁芯51位于防尘罩49中,纵向伺服电机4a固定在滑板43上,纵向伺服电机4a的转轴上固定有纵向丝杆4b,纵向丝杆4b与纵向螺母4c螺接在一起,纵向螺母4c固定在磁芯51上;
太阳能光伏板2和市电6给双向储能逆变器7供电,双向储能逆变器7给车库磁耦合线圈5供电,电动车8上固定有车载磁耦合线圈9、充放电控制电路10和电动车蓄电池81,车库磁耦合线圈5的磁芯51与车载磁耦合线圈9的磁芯结构相同且相对,车载磁耦合线圈9通过充放电控制电路10给电动车蓄电池81充电;
电动车蓄电池81上电连接有蓄电池检测器11,蓄电池检测器11的检测信号输送给MCU控制单元12,MCU控制单元12控制双向储能逆变器7是否给车库磁耦合线圈5供电;
光电探头13固定在箱体41上,光电探头13检测电动车8的位置信号,光电探头13的位置信号输送给MCU控制单元12,MCU控制单元12根据光电探头13的位置信号控制横向伺服电机42和纵向伺服电机4a工作。
所述光电探头13有四个,分别固定在箱体41的四个角部。
工作原理:当电动车8停在立体停车库1中的停车位上后,光电探头13检测电动车8的位置信号,光电探头13的位置信号输送给MCU控制单元12,MCU控制单元12根据光电探头13的位置信号控制横向伺服电机42和纵向伺服电机4a工作。让车库磁耦合线圈5的磁芯51与车载磁耦合线圈9的磁芯调整到正相对的位置,这样能提高无线充电效率。采用上述结构上的设计,在实际停车过程中,即便出现位置偏差,在充电时也能够保证车库磁耦合线圈5和车载磁耦合线圈9处于同轴位置时,保证充电效率最高。
采用上述技术方案,电动汽车在立体停车库下,在充电模式下,如果太阳能充足,直接利用太阳能对电动汽车充电,若无电动汽车执行充电操作,则将太阳能直接并入电网;如果太阳能不足,则通过电网对电动汽车充电,两者可以采用协同充电;由于本发明采用双向储能逆变器,在放电模式下,电动汽车对电网进行放电,电动汽车在停车位就能完成蓄能、释能过程,同时电动汽车作为移动储能工具,通过用户意愿设定和电网智能调度,能更好地发挥削峰填谷的作用,有效减轻有线集中充电对电网产生的冲击,平衡负荷,提高电网稳定性,有效节约能源。
