Can't handle the national grid, Tesla's first car mostly tragedy-Tesla, Tesla,Model s, charging electric vehicles-IT information Can't handle the national grid, Tesla's first main tragedy
"Two days before the company engineer testing, filling a dozen hours, only less than 100 miles, according to the case, if you use frequently, almost every day to recharge. "The first Tesla owner, Xu Liang (a pseudonym) still has any concerns about the car. He told reporters that worry most about is the issue of charging, if you use the normal outlets too slow, I intend to put a charging, which cost about 10,000 yuan.
In fact, Tesla prior to entry into China, their charging infrastructure construction was controversial. Today, the Tesla has announced high profile 734,000 yuan "prices", but the reporter learned from the situation, and its preparations for entering the Chinese market are not sufficient and Max get in the way of it's power system . The industry believes that, If you can't handle the national grid, did not rule out the Tesla built their own solar-powered charging station .
According to Tesla's commitment to China's first batch of Model s will take place in March, but Tesla still shows no signs of building charging stations, public charging infrastructure only try Beijing fangcaodi Jingang service station stores and two, so the first majority owner home recharge only. In order to accelerate the pace of charging, the owner needs to change grid lines at home, and Tesla to let property owners with their own communications.
Rechargeable security concerns
In the Tesla showroom, reporters saw a Model s Center at the exhibition hall is being charged, is a normal household outlet.
"Tesla's DC socket there are many, but with an ordinary outlet slowest most unstable. Therefore, we recommend that customers install our charging, in order to provide stable current. Charging rate also depends on the size can provide power. "The showroom staff, told reporters.
According to Tesla staff, determined by the voltage and current of electricity. Grid systems by China and the United States, unlike electricity 220V voltage, currents, in principle, the greater the power becomes stronger.
A national grid, insiders told reporters: " to improve power, either upgrading or increasing current. But upgrading makes current instability and, in General, only the factory can apply to the high voltage of 380V, electricity is difficult to ratify. Increase current needs to be approved by the local power supply company. At the same time, meter, circuit needs to change accordingly, otherwise there will be a security risk . ”
Those reminders, current electricity current interval between 1.5A to 6 a, wanted from 10A to 100A, it is difficult to be approved by the Bureau . Unless Tesla with local power supply Bureau coordination, would be too much.
Xinhua learned from several other Tesla owners and current attitude is Tesla charging, hope that the consultation with the property owners themselves, departments which did not inform owners of the application, are not arranged.
In addition, the owner to modify the circuit to increase current, still needs approval by the Fire Department, leaving these puzzle Tesla owners .
According to the survey, China's first batch of Tesla owners to engage in financial, Internet and successful people are the majority . These owners purchased the Tesla more out of worship of technology, treating them as status symbols.
Tesla now public charging network in China have not yet established, these drivers will charge also has its own garage, if it is not a single compound, at least parking spaces need a recharge. It seems that it's just a local despot "toys".
搞不定国家电网，特斯拉首批车主要悲剧 - 特斯拉,Tesla,Model S,充电桩,电动汽车 - IT资讯搞不定国家电网，特斯拉首批车主要悲剧
“前两天公司派工程师检测，充了十几个小时电，只能开不到100公里，按照这样的情况，如果使用频繁，几乎每天都要充电。”作为首批特斯拉车主，徐亮(化名)对即将到手的爱车仍有一丝担忧。他告诉记者，最担心的就是充电问题，如果用普通的插座充电太慢，我打算装一个充电桩，花费约1万元。
事实上，在特斯拉入华之前，关于其充电设施的建设颇有争议。如今，特斯拉虽然已高调宣布其73.4万元的“心动价”，但从记者了解到的情况看，其进入中国市场的准备工作并不充分，最大的拦路虎恐怕就是电力系统。业内人士认为，如果搞不定国家电网，不排除特斯拉自行建太阳能充电站的可能。
按照特斯拉的承诺，中国第一批Model S将于3月份交车，但特斯拉至今仍没有建设充电站的迹象，公共充电设施只有北京市芳草地试营店和金港客服站两处，因此首批车主大部分只能在家里充电。为了加快充电速度，车主需要变更家中的电网线路，而特斯拉却让车主自行与物业沟通。
充电安全惹人担忧
在特斯拉展厅，记者看到，位于展厅正中的一辆Model S正在充电，用的就是普通的家用插座。
“特斯拉的充电插口有很多种，但用普通插座充电最慢最不稳定。因此，我们建议客户安装我们的充电桩，以便提供稳定的电流。充电速度，还取决于能提供的电力大小。”展厅服务人员告诉记者。
根据特斯拉工作人员介绍，电力由电压和电流决定。由于中国电网的制式和美国不一样，民用电一般只支持220V电压，原则上电流越大电力越强。
一位国家电网内部人士告诉记者：“要想提高电力，要么提高电压，要么加大电流。但是提高电压会使电流不稳定，而且一般只有工厂才能申请到380V的高压，民用电很难批准。加大电流需要得到当地供电局的批准。同时，相应的电表、电路都需要变更，否则会有安全隐患。”
上述人士提醒，目前民用电的电流区间一般在1.5A到6A之间，想要改成10A至100A，很难得到供电局的批准。除非特斯拉与各地供电局协调好，个人很难。
记者从其他几位特斯拉准车主处了解到，目前特斯拉对充电问题的态度是，希望车主自行与小区物业协商，并没有告知车主具体该找哪些部门申请，也没有给予统一安排。
除此之外，车主若要修改电路加大电流，还需要得到消防部门的审批，这些难题特斯拉统统丢给了车主。
根据记者调查，中国首批特斯拉车主以从事金融、互联网行业的成功人士居多。这些车主购买特斯拉更多是出于对技术的崇拜，视其为一种身份的象征。
目前特斯拉在中国的公共充电网络还没有建立起来，这些车主要充电还需要有自己的车库，如果不是独栋大院，至少也需要有个能充电的车位。看来，这只是土豪们的“玩具”。
