让电动汽车越跑越畅快

2017-09-05 06:50:37   中国经济网

“2014年投运以来,该站两个方向月度充电电量和充电次数呈增长趋势。”国网北京市电力公司营销部智能用电处工程师潘鸣宇说,车主可以通过e充电APP方便地查找到各条高速路上的所有充电站点,并且能够知道每个站点的距离、充电桩数量和空闲状态等信息,让车主出行没有里程忧虑。

目前,我国已建成全球覆盖范围最广的充电服务网络。数据显示,2006年以来,国家电网建设充换电站5526座、充电桩4万余个,建成“六纵六横两环”高速公路快充网络,覆盖16个省份、121个城市。其中,高速公路快充站平均间距不超过50公里。国家电网专职新闻发言人王延芳透露,到2020年,国家电网将建成充电桩12万个,城际快充网络覆盖京津冀鲁、长三角地区所有城市和其他地区主要城市202个、高速公路3.6万公里,做到郊区县服务半径不超过5公里、环城区服务半径不超过3公里、城区服务半径不超过1公里。

制定中国充换电标准体系

累计完成国家标准22项、行业标准27项、企标61项,创新建立具有自主知识产权、技术领先的中国充换电设施标准体系,与美、日、欧标准并列成为国际4大充换电标准体系

国际竞争,标准先行。目前,国家电网已建成具有中国特色的充换电标准体系。

“国家电网还立项国际电工委员会(IEC)国际标准4项,已发布3项,这实现了电动汽车领域由我国主导完成国际标准零的突破,为跨国充电设施互联互通提供了技术遵循。”中国电力企业联合会标准化中心副主任刘永东说。

在充电设施标准执行过程中,国家电网公司规范引领车桩兼容,实现车桩充电接口互联互通。推动标准执行和落地,率先开展充电设施新国标升级工作,启动国家电网公司充电桩新国标改造,提高车辆与充电桩的适配性。建成充换电设施实验验证中心,获得多个国际权威检测机构授权资质,为推动电动汽车充换电设施产业国际化提供了有力保障。

在标准建设的同时,国家电网还不断创新充电网络建设方式。在众多充电站中,京津塘高速徐官屯北侧服务区充电站尤为特别。记者采访发现,该站充分利用屋顶、地面及充电桩顶棚空间安装光伏发电设备,实现光储充一体化发展,充分利用绿色能源发电,采用“自发自用、余电上网”模式,通过智能监控对整个光储充系统进行调配,实现高速公路服务区及交通出行的绿色用电。

“未来还将利用高速公路护坡空间建设光储示范工程。”国家电网电动汽车公司市场营销中心副主任彭晓峰透露,2016年我国高速公路总里程已突破13万公里,如果在目前已建成约3000个服务区及沿线护坡全面推广该项目成果,全国光伏总装机容量可新增约20吉瓦,相当于新建一个三峡水电站。
