国内首个新型实用纯电公交示范项目落户青岛

2017-09-27 13:47:54   

央广网青岛9月27日消息(记者王伟 通讯员刘珊 袁灵秀)国内首批“智能搭线快充”新型实用纯电公交车27日在青岛上路运营。

据了解,新型实用纯电公交采用搭线充电技术,具备空中快充、边走边充、节省空间占地、绿色节能等多项优势,可以大大提高公交企业电动公交车的综合运营效率,减少市民的等车时间。同时,青岛交运温馨巴士推出交运智慧云平台,危险品检测系统、驾驶行为监控平台、安全预警系统、导盲系统以及人脸识别、客流量监控等多项国内顶尖的智能物联网信息技术也将在20辆电动公交上搭载使用。

27日当天,由大唐电信科技产业集团、交运集团共同成立的国内首个智能交通研究中心也正式落户青岛,研究中心将致力于推进国内电动公交车的智能化、规模化发展,让城市公共交通更加绿色、便捷、顺畅。

记者在采访中了解到,新型实用纯电公交采用了国内最新的“边走边充”移动充电技术。驾驶员在驾驶室里按下充电按钮,公交车就会自动升起集电弓,通过感应系统寻找充电线网的位置,只要车辆与充电线网的位置偏差在方圆1.5米的感应范围内,集电弓都会准确无误地捕捉到空中充电线网。另外,在车顶还专门装有摄像头,以便驾驶员通过监控监测到集电弓的升降情况,从而及时调整车辆位置。

与以往公交车不同的是,新型实用纯电公交具有动力电池保护功能,在快充充电时当电量达到80%-90%时,车辆就会智能切换到慢充模式。另外,新型纯电公交车是采用搭线充电技术,目前,高新区建设的充电线网约长100米,外侧是快充线网,只需充电5分钟,车辆就可以运行40公里,主要用于车辆临时补电;内侧是慢充电网,车辆结束运行任务后可按前后顺序依次停车充电,内外侧充电线网可以同时为30辆车充电。除了快充、慢充两种方式,新型实用纯电公交车还可以通过充电桩的充电枪充电,适应多种运营环境。为了在充电时保障车辆安全,这些纯电动公交车都带有智能限速功能,一旦开始充电,行驶速度将被自动限制到5公里/小时以下,避免移动充电时车速过快带来的安全隐患。

记者了解到,从2010年国内开始推广新能源车辆应用至今,各地纯电动公交车均采用充换电站换电模式或充电桩充电模式。此次,交运温馨巴士场站中建成的充电线网是采用空中快速充电模式,这在全国尚属首次应用,开创了纯电动公交车充电的新模式。该模式下,不占用场站地面面积,也不影响场站原有停车线、行车通道的布置。所以,现有的大部分公交场站都能满足项目需求,不需要再增加新的场站用地。
