智能电动车充电桩联网方案系统需求 充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)基础(chu)设施(shi)主(zhu)要(yao)包(bao)括各类(lei)集中式充(chong)(chong)(chong)(chong)换电(dian)(dian)(dian)站和(he)分散(san)式充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)桩(zhuang)。根据发展指南,计(ji)划到2020 年(nian),新增集中式充(chong)(chong)(chong)(chong)换电(dian)(dian)(dian)站超过 1.2 万(wan)座,分散(san)式充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)桩(zhuang)超过 480 万(wan)个(ge),以满(man)足全(quan)国 500万(wan)辆电(dian)(dian)(dian)动汽车充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)需求。由于充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)设施(shi)位置分散(san),数量(liang)庞大,为保证用户体验和(he)运营效率,必(bi)须(xu)要(yao)提供充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)导(dao)航(hang)、状(zhuang)态查(cha)询、充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)预约、费(fei)用结算等服(fu)务(wu)(wu),而要(yao)提供这些(xie)服(fu)务(wu)(wu),就必(bi)须(xu)要(yao)对这些(xie)充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)设施(shi)进行联网(wang)并构建充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)智能服(fu)务(wu)(wu)平台。充(chong)(chong)(chong)(chong)电(dian)(dian)(dian)桩(zhuang)联网(wang)的具体要(yao)求如下(xia):
针对(dui)充电(dian)桩联(lian)网需求(qiu),讯宜捷物联(lian)网科技凭(ping)借(jie)自身在设备联(lian)网领域的(de)技术优势以及多年来在电(dian)力系统中的(de)成功经验,推出充电(dian)桩智能联(lian)网方案(an)。 解决方案介绍 针(zhen)对不同的充电设施及(ji)客户需求,提供差异化的解决方案。 (1)针(zhen)对(dui)分散式充电(dian)桩(zhuang) 对(dui)于居(ju)民区或单位停(ting)车场等场所的分散式充电(dian)桩,采(cai)用讯宜(yi)捷物联网网络(luo)工业级无(wu)线(xian)数据终(zhong)端 (DTU)进(jin)行联网。充电(dian)桩控(kong)(kong)制板与(yu)(yu) DTU 通过串口(kou)相连,无(wu)线(xian) DTU 通过运(yun)营(ying)商的 GPRS/3G网络(luo)自动拨号联网,并与(yu)(yu)充电(dian)运(yun)营(ying)企(qi)业的监控(kong)(kong)运(yun)营(ying)中心建立连接,从(cong)而搭(da)建充电(dian)设(she)施与(yu)(yu)监控(kong)(kong) 运(yun)营(ying)中心之(zhi)间的透明通道。系统网络(luo)拓扑如下:
(2)针对(dui)集中式充换电站或群充电系统 对于公交、出租、环卫、物流以及高速公路等公共服务领域的充电基础设施,一般以建设集中式充换电站为主,或者有些充电运营企业采用箱变等技术推出群智能充电系统。这种情况,讯(xun)宜捷物联网(wang)网(wang)络(luo)提供工业级路(lu)由器产品(pin)实现充(chong)电(dian)(dian)设施(shi)的(de)(de)联网(wang)。集(ji)中式充(chong)电(dian)(dian)站的(de)(de)各充(chong)电(dian)(dian)桩采用以(yi)太网(wang)方(fang)式组成局域网(wang)(如果是群充(chong)电(dian)(dian)系(xi)统(tong),则整个系(xi)统(tong)有集(ji)中的(de)(de)采集(ji)控(kong)(kong)制(zhi)单元),然(ran)后通过工业路(lu)由器作(zuo)为(wei)统(tong)一的(de)(de)网(wang)关(guan)连接专(zhuan)网(wang)或 Internet,并最终与充(chong)电(dian)(dian)运营(ying)(ying)企业的(de)(de)监控(kong)(kong)运营(ying)(ying)中心(xin)建立连接,实现充(chong)电(dian)(dian)设施(shi)与监控(kong)(kong)运营(ying)(ying)中心(xin)之间的(de)(de)双向数据传(chuan)输。系(xi)统(tong)拓扑(pu)如下(xia):
