81,000 charging are still enough: new energy car charger-new energy solutions, post-IT information
National Union of electric vehicle charging infrastructure for statistical data show that as of the end of June this year, China's total public charging 81,800; DC 13,500; DC combined 16,500; exchange of 51,800; end-2015 or 65%. Private post total of 55,400, more about 12% over the end of 2015, piling their cars than about 4:1.
Meanwhile, Niu Jinming, Beijing new energy vehicle development promotion Center Director at a recent Conference of the "2016 China charging Innovation Summit" sighs on, "post built a lot now, but people don't feel more convenient. ”
Up to 170,000 vehicles a new energy vehicles in China in the first half, growth reached 126%, new energy automobile sales growth is still higher than the battery's construction, that is charged to the owners of new energy is not one of the reasons. In addition, the charging standard is not unified, property not matching and other factors have become important reason to use the convenience of new energy vehicles.
Uniform standards to "interoperability"
Recently, the reporters came to the daily news located in Xicheng District, Beijing maliandao tea city near public charging to the national grid, was showing the car to charge Ms Zhao told reporters, if we are not charging, then buy EV must be done before "homework", so you can avoid a lot of unnecessary troubles.
Ms Zhao said further: "I now is a lot of post operator customers, stood for a long time in the car and all the new energy to the national grid's charge card, installed on the mobile phone APP has 4 on post, the only way I will settle down a bit. ”
Meanwhile, some electric car owners to make potential reporters reflect, public charging car charging, when the charge reaches above 90%, post will no longer continue to charge. Released as potential car's official explanation is that this issue belongs to the public charging voltage is not cause enough to make potential output voltage of electric vehicle charging stations to the 220Vdc~550Vdc coverage, post screen display "charging voltage too high" means, when vehicle battery voltage is consistent with common maximum charging output voltage, it can no longer recharge the vehicle battery.
For these problems, Liu Yongdong, Deputy Director of China electricity Council standardization Center, are charging standards are not unified, result of interoperability cannot be achieved.
Liu Yongdong believes that electric vehicles were to be achieved, charging, operator of three parties "interconnection", there are three aspects need to be addressed. "The first is compatibility problem, different cars in different piles on the understanding of differences, which have access problems, car and will not charge. Since December 2015 electric conduction charging system 1th Department points: General requirements (following referred to new GB) introduced Hou, new old GB alternating brings series car pile match difficult problem, the enterprise to according to ' new GB ' a standard to production, and manufacturing and sales, perfect charging standard of certification and detection system; second is information compatible problem, currently market Shang on charging pile of APP many, ' cohabitation '' Fighting each other ' and uneven quality of service, not only fails to provide users with convenient, but also brings problems; the third is the inconvenience of trading now, post carrier settlement is ' set ' for owners of consumer inconvenience. ”
From this point of view, harmonization of standards is the realization of electric vehicles and charging, operator of the tripartite "interconnection" of protection. It is understood that Beijing, Shanghai and Shenzhen have standard pilot work, the work will be completed by the end of August, and information exchange standards will be launched in September and formally announced to the society.
Liu Yong-dong told reporters, the new national standard will be introduced after January 1, 2017. "The operators in accordance with the rules, said that interconnection would to some extent be resolved."
Public post was "fill"
In fact, with the exception of "knee" standards are not unified, all spaces and properties do not support is another important reason the charge.
In Beijing, for example, as of January 2016, Beijing had 2,108 Community construction of new energy cars for personal use with charging facilities, total number of City Community construction community with only 40%.
"If property not tie, Government or power wants to intervention has must difficult, Government hard forced property, and power also only tube to Community ' wall ' outside, ' wall ' within of thing also return property management; but property worried of problem, we now is to solution, like charging security problem, and fire problem, and construction installation problem,, these are contains in we now amendment of ' charging pile new GB ' among, while, with incentive mechanism of increasingly perfect, property company also will in is big degree Shang change ' More about doing less ' attitude is negative. "Liu Yong-dong said in an interview with the business daily reporters.
It is understood that the National Energy Board in the electric vehicle charging infrastructure construction program, proposed in the draft, by 2020, the number for filling station in the country will reach 12,000, post up to 4.5 million; the proportion of electric vehicles and charging facilities close to the standard of 1:1.
In this regard, Liu Yongdong said, "actually, our route is to allow charging for design more people at home, Office space charge, without public charging to charge for public charging function is more on vehicles ' repair ', rather than ' charging '. ”
8.1万个充电桩仍不够用：新能源车充电难待解 - 新能源车,充电桩 - IT资讯
国家电动汽车充电基础设施促进联盟的统计数据显示，截至今年6月底，我国共有公共充电桩8.18万个；其中直流桩1.35万个；交直流一体桩1.65万个；交流桩5.18万个；较2015年底增长65%。私人充电桩共计5.54万个，较2015年底增长约12%，车桩比约4：1。
与此同时，北京市新能源汽车发展促进中心主任牛近明在近日召开的“2016中国充电桩创新峰会”上感叹道，“充电桩现在建了不少，但是老百姓并没有感觉多方便。”
上半年我国新能源汽车销量达到17万辆，同比增幅达到了126%，新能源汽车的销量增速仍然高于电池充电桩的建设速度，这是令新能源车主感到充电不方面的原因之一。除此之外，充电桩标准不统一，物业不配套等因素都成为制约新能源汽车使用便利性的重要原因。
统一标准才能“互联互通”
日前，《每日经济新闻》记者来到位于北京市西城区马连道茶城附近的国家电网公共充电桩，正在给爱车充电的赵女士向记者表示，如果自己没有充电桩，那么在买纯电动汽车前一定要做足“功课”，这样可以避免很多不必要的麻烦。
赵女士进一步表示：“我现在是很多充电桩运营商的客户，车里长期放着国家电网和普天新能源的充电卡，手机上安装关于充电桩的APP就有4个，只有这样，我心里才踏实些。”
同时，有腾势电动车的车主向记者反映，在公共充电桩为车充电时，当电量达到90%以上，充电桩便不再继续充电了。而腾势汽车的官方解释是，此问题属于公共充电桩电压不够引起，腾势电动车的充电站输出电压能覆盖220Vdc~550Vdc的范围，充电桩屏幕显示“充电电压过高”是指，此时车辆动力电池的电压已跟公用充电桩的最大输出电压一致，故无法再继续对车辆动力电池充电。
对于这些问题，在中国电力企业联合会标准化管理中心副主任刘永东看来，都是充电桩标准不统一，无法实现互联互通造成的。
刘永东认为，要想实现电动汽车、充电桩、运营商三方的“互联互通”，目前有三方面问题需要解决。“第一是车桩兼容问题，不同的车不同的桩在理解标准上存在差异，这就带来接入性的问题，车就充不了电。自2015年12月《电动汽车传导充电系统第1部分：通用要求》（以下简称新国标）出台后，新老国标交替带来一系列车桩匹配难问题，各企业要按照‘新国标’一个标准去生产、制造和销售，完善充电标准的认证和检测制度；第二是信息兼容问题，目前市面上关于充电桩的APP众多，‘鱼龙混杂’‘各自为战’，服务质量参差不齐，不但没有为用户提供方便，反而还带来了困扰；第三是交易不便的问题，目前，充电桩运营商的结算方式也是‘各有一套’，为车主的消费带来不便。”
由此来看，统一标准才是实现电动汽车、充电桩、运营商三方“互联互通”的保障。据了解，北京、上海、深圳已展开标准试点工作，该工作将于8月底完成，而信息交换标准将于9月份出台，同时向社会正式公布。
刘永东对记者表示，新国标将于2017年1月1日后开始实行。“各运营商如果按照这套规则进行，应该说互联互通问题会在一定程度上得到解决”。
公共充电桩的属性是“补电”
事实上，除“车桩”标准不统一外，无车位以及物业不配套也是导致充电难的另一重要原因。
以北京市为例，截至2016年1月，北京已有2108个小区配建了新能源小客车自用充电设施，配建小区数量仅占全市小区总数四成。
“如果物业不配合，政府或者供电局想要介入有一定困难，政府很难强求物业，而供电局也只能管到小区‘围墙’外，‘围墙’内的事还归物业管理；不过物业担心的问题，我们现在正在着手解决，比如充电安全问题、消防问题、施工安装问题等，这些都包含在我们现在修订的‘充电桩新国标’当中，同时，随着激励机制的日趋完善，物业公司也会在很大程度上改变‘多一事不如少一事’的消极心态。”刘永东在接受《每日经济新闻》记者采访时表示。
据了解，国家能源局在《电动汽车充电基础设施建设规划》草案中提出，到2020年，国内充换电站数量将达到1.2万个，充电桩达到450万个；电动汽车与充电设施的比例接近标配的1：1。
对此，刘永东表示，“实际上，我们设计的充电路线是让更多的人能够在家里、办公场所充电，而不用到公共充电桩充电，因为公共充电桩的职能更多的是对车辆进行‘补电’，而非‘充电’。”
