Description

电动公交车沿线站点无线充电***
技术领域
本发明涉及一种电动公交车充电***，具体地讲，本发明涉及一种电动公交车无线充电***，特别是一种电动公交车沿线站点无线充电***。
背景技术
城市人口多，密度大，需要配置足够数量的公交车才能满足公共交通需求。为了进一步提高城市空气质量，国家环保政策严格限制城市公交车的尾气排放。在现有技术条件下，零排放的电动汽车已成为公共交通的优选车辆。电动公交车耗用的电能由自备储能***供应，储能***通过充电补充能源。目前，电动公交车充电均在指定充电站内完成，所用电能主要由公共电网提供。这种供电方式简单、可靠，充电容易，能够满足电能补充要求。电动公交车的续航能力与配置的储能***容量成正比关系，即储能***容量大，续航则有远些。但是，储能***容量大，自重和体积相应加大，由于电动公交车受结构和载重限制，配置的储能***容量不可能足够大，所以在用的电动公交车续航能力有限，只有通过及时充电来满足使用要求。作为城市公共交通的车辆使用频率相对高，一旦充电不及时，或估计不足，易造成中途缺电抛锚事故。此类交通质量事故是该行业的大忌，不可以频发。
发明内容
本发明主要针对现有电动公交车只能集中定点的不足，提出一种结构简单、使用方便的电动公交车沿线站点无线充电***，该***应用清洁能源，能够做到在停靠期间及时、灵活补充电能，完全避免发生途中缺电抛锚事故。
本发明通过下述技术方案实现技术目标。
电动公交车沿线站点无线充电装置，它包括沿线站点地面、棚架和靠站的电动公交车。其改进之处在于：所述棚架顶层朝阳安置光伏组件，光伏组件的输出端连接棚架内置的光伏控制装置，棚架内还配置储能装置、逆变电路和信号控制电路。所述电动公交车底部面朝站点地面处配置电磁场接收装置和整流滤波电路。所述站点地面在指定电动公交车停靠位置上，正对着车底部安置的电磁场接收装置预埋电磁场发射装置，电动公交车停靠时逆变电路向电磁场发射装置供电。所述光伏组件将太阳能转换成电能，与其相连接的光伏控制装置一方面控制光伏组件电能输出，另一方面对一侧连接的储能装置进行充放电管理。所述逆变电路将光伏组件输出的直流电转换成电动公交车要求的高频交变电流。所述信号控制电路控制逆变电路输出的电压值，以实现输入功率和输出功率相平衡。所述电磁场发射装置将从逆变电路引入的高频交变电流转换成交变磁场向上发射。所述电磁场接收装置无线接受到电磁场发射装置发射的交变磁场后，将交变磁场转换成交流电，输出的交流电经整流滤波电路转换成电压值恒定的直流电，该直流电直接输入到停留的电动公交车储能设备中。
作为进一步改进方案，所述光伏组件应用柔性光伏板制造。
作为进一步改进方案，所述站点地面预埋的电磁场发射装置与电动公交车底部安置的电磁场接收装置垂直距离H=15～20mm。
本发明与现有技术相比，具有以下积极效果：
1、电动公交车在沿线每个站点停靠时都得到无线充电，由于及时补充电能，有利于提高续航能力，显著减少发生缺电抛锚事故，大大提高服务质量；
2、在沿线各站点配置无线充电装置，电动公交车到站即充，离站即停，此充电模式一方面充分利用清洁能源，另一方面充分利用时间，做到充电不影响运行秩序。
附图说明
图1是本发明结构示意图。
图2是本发明原理方框图。
具体实施方式
下面通过附图并结合实施例，对本发明作进一步说明。
附图所示的电动公交车沿线站点无线充电装置，它包括沿线站点地面1、棚架2和靠站的电动公交车3。所述棚架2是站点的基础设施，在棚架2顶层朝阳的一面安置光伏组件2.1，本实施例光伏组件2.1应用柔性光伏板制造。光伏组件2.1将太阳能转化成电能，电能经输出端送到棚架2内置的光伏控制装置2.2中。光伏控制装置2.2一方面控制光伏组件2.1电能输出，另一方面对一侧连接的储能装置2.3进行充放电管理。栅架2内还配置逆变电路2.4和信号控制电路2.5。为了达到无线充电目的，本发明在电动公交车3底部面朝站点地面1处配置电磁场接收装置3.1和整流滤电路3.2，站点地面1在指定电动公交车3停靠位置上，预埋的电磁场发射装置1.1正对着车底部安置的电磁场接收装置3.1，为了确保无线传输质量，预埋的电磁场发射装置1.1除与车底部悬置的电磁场接收装置3.1上下正面相对，而且垂直间距H有尺寸限制，本实施例H=20mm。结构中电磁场发射装置1.由逆变电路2.4供电，逆变电路2.4将光伏组件2.1输出的直流电转换成电动公交车3要求的高频交变电流。所述信号控制电路2.5在结构中负责控制逆变电路中2.4输出的电压值，其作用是控制输入功率和输出功率相平衡。受逆变电路2.4和信号控制电路2.5控制的电磁场发射装置1.1预埋在站点地面1指定位置处，当电动公交车3按指定位置停靠站点时，电磁场发射装置1.1将从逆变电路2.4引入的高频交变电流转换成交变磁场向上发射。此刻，电动公交车3车底部安置的电磁场接收装置3.1无线接收到电磁场发射装置1.1发射的交变磁场，电磁场接收装置3.1将交变磁场场转换成交流电，输出的交流电经整流滤波电路3.2转换成电压恒定的直流电，该直流电直接输入到停留的电动公交车3储能设备中。
在城市某条公交线每个站点都设置本发明无线电充电装置，实现车到站即充，离站即停。若该线路设有20个站点，每次电动公交车平均停靠30秒钟，则运行一趟可得10分钟的充电。由于做到及时补充能源，有利于提高电动公交车3的续航能力，可避免发生缺电抛锚事故。另外，此种充电模式在电动公交车3停靠站时自动补充电能，即不占用时间，又不影响正常运行秩序，而且充分利用清洁能源。此技术方案的实际应用既经济，又环保，特别适合城市公交配套。
