Description

一种汽车无线充电对准匹配系统及方法 技术领域
本发明涉及无线充电技术领域，具体是一种应用光敏传感器及磁传感器的汽车无线充电对准匹配系统及方法。
背景技术
现有的采用无线充电方式的电动汽车在进入无线充电站充电时，需要将车载底部无线充电接收板与地面的无线充电发射板对准才能保证充电效率的最大化，现有的对准方式一般是司机控制汽车根据充电站的定位标志来定位对准，或者是根据车载电子指示系统的定位指令移动汽车或控制充电接收板对准无线充电发射板，无论采用上述哪种方式都是需要驾驶员的人工控制来实现无线发送、接收板的对准，这个过程缓慢而低效。
为此，一篇申请号为201110276928.9的发明专利，公开了一种强电磁耦合式电动汽车无线充电装置，其包括市电电源，初级整流滤波器，初级变换器，可分离电磁耦合器的原边线圈，可活动原边线圈支架，可分离电磁耦合器副边线圈，聚磁铁芯，可活动副边线圈支架，次级整流滤波器，充电控制器，蓄电池，电动汽车。把工频交流电输入到初级整流滤波器，从初级整流滤波器输出稳定的直流电，经初级变换器进行高频逆变变换后的高频交流电，该交流电输送至可分离电磁耦合器的原边线圈，可分离电磁耦合器的原边线圈内有聚磁铁芯，分离电磁耦合器的原边线圈通过可活动原边线圈支架可以上下移动与可分离电磁耦合器副边线圈通过可活动副边线圈支架上下移动发生强电磁耦合，这样实现高磁密度的能量传输。该专利采用的是分别能够上下移动的原边线圈装 置和副边线圈装置，在移动汽车使车上的副边线圈正好对准到原边线圈上方后，两装置上下移动并将原副边线圈贴近来实现提供电能转换效率的目的；该专利方案的缺点是需要司机移动汽车以实现副边线圈正好对准在原边线圈上才能满足实现该专利目标的前提条件，并且该装置是上下移动，在充电结束后，需要一个时间来保证原边线圈和副边线圈回收到初始位置后汽车才可驶离，增加了汽车整个充电的过程程序和时间，并容易由于司机提早移动汽车而导致原副边线圈装置被刮蹭而损坏。
另有一篇申请号为201080058025.7的发明专利，公开了一种电动汽车用无线充电系统及充电方法，其充电系统包括：电力控制装置，其设置于无线充电所并控制所有无线电力传输装置；设置于停车区域的无线电力传输装置及地面近距离无线通讯模块；无线电力传输装置，其以多个数量设置于停车区域的地面、选择运行随电动汽车的充电信息对向的一部分无线传输面板；以及，在电动汽车的底部安装能够升降的多个无线传输面板，在电动汽车内具备无线电力接收机和无线充电终端及近距离无线通信模块和充电控制器，通过无线充电终端驾驶员的选择实现无线充电的最优化。该专利在车底部布置有多个接收线圈，当车停在充电车位上后由司机选择最优效果的接收板来实现最优化无线充电，该专利在发射机收装置最优定位实现上有以下确定，一是需要司机来人工选择合适的接收板来工作，二是在车底布置多个接收板成本昂贵。
另外一篇申请号为201310043965.4的发明专利，公开了一种电动汽车无线充电系统，解决了现有的原边线圈与副边线圈对接匹配难的问题。该电动汽车无线充电系统，包括无线发射板和无线接收板，还包括供电动汽车停泊的支撑平台和用于支撑无线发射板的支撑组件；无线接收板设置于电动汽车的底部且其接收面朝下底面；支撑组件和支撑平台之间至少设有能调节无线发射板高度 的位置调节机构。可根据车辆位置快速调整无线发射板的高度，缩短无线发射板与无线接收板的距离，有效降低了由于车辆及无线发射板的位置引起的电量传输损耗，提升了能量传输效率，辐射也相应降低。该专利采用可移动的无线充电发射板来实现发射板与接收板的对准定位以实现提高无线充电传输效能，该专利的缺点是可移动的发射板需要在车位地面进行较大工作量的地面破土工程，并需要挖掘出足够其装置预埋的空间，如采用金属架结构作为支撑面则增加了整个系统的成本，且金属架结构支撑面也存在着金属对电磁波吸收发热的危险可能。
