Description

一种架空轨道式移动充电系统及方法
技术领域
本发明涉及电动汽车充电技术领域，特别是一种架空轨道式移动充电系统及方法。
背景技术
随着电动汽车的发展，电动汽车充电难、充电不方便的问题日益突出。目前，电动汽车充电主要采用固定安装的交、直流充电桩为其充电。交流充电桩就近接入0.38千伏低压配电网提供220V或380V交流电，从交流充电桩输出的是交流电，由车载充电机完成交直流变换。直流充电桩接入公变或专变并提供380V交流电，从直流充电桩输出的是直流电，由非车载充电机完成交直流变换。
目前，采用固定的充换桩给电动汽车充电，用户必须专门把车开到有充电桩的地方去充电，无法将居住地、工作地、目的地的停车时间转为充电时间；用户充完电后再开车离开，充电排队时间久，使用很不方便；而且，前车充完电后如未及时驶离而继续占用着充电车位，还会影响充电桩给下一辆车充电，使得充电桩利用率普遍不高。受配电网容量和土地资源的制约，无法在城区新建大量的充电设施来满足充电需求。另外，传统充电桩的充电无序行为还给配电网带来巨大压力。
发明内容
有鉴于现有技术的上述缺陷，本发明的目的就是提供一种架空轨道式移动充电系统及方法，能够突破了充电过程中场所的限制，无需再专门跑去充电站充电，非常适合用于在大型停车场为静止停放的电动汽车充电；本发明的系统使用率高，可大量减少充电桩的建设，可节约大量的配电网改造费用。
本发明的目的之一是通过这样的技术方案实现的，一种架空轨道式移动充电方法，它包括有：所述方法步骤如下：
S1：充电用户向主控单元发出充电请求；
S2：主控单元接收到所述充电请求指令后自动安排停车位，并根据充电请求信息进行充电排序，同时所述主控单元向牵引装置发出移动指令；

进一步，所述步骤S6中还包括有充电状态检测，所述检测流程如下：
S61：充电用户将电缆线上的充电插头插入电动汽车的充电插座中，充电控制器检测所述充电插头与所述电动汽车的充电插座是否连接完成；如检测到连接完成，则开始给待充电的电动汽车进行充电；反之，则进行步骤S62；
S62：若检测到该充电插头与充电插座出现连接异常，提示充电用户重新连接；
S63：充电用户重新连接后，则进入步骤S61。
进一步，所述步骤S62还包括有：
S621：判断充电用户是否在120秒内进行重新连接，若未进行，则停止响应本次充电请求，进入步骤S9；反之，则进入步骤S63。
进一步，所述步骤S63还包括有：
S631：判断充电用户重新连接次数是否超过3次，若超过3次，则进入步骤S9；反之，则进入步骤S61。
本发明的另一个目的是通过这样的技术方案实现的，一种架空轨道式移动充电系统，包括有：AC/DC装置、母线、导轨、牵引装置、定位装置、供电开关、充电控制器、主控单元、人机交互单元、计量计费单元、线缆传送装置、充电线缆、充电插头；
