1【原创】比亚迪的电动汽车神话 41 同人于野 2007-08-09 23:49:24
　　今天看到比亚迪 F6 下线的新闻，这个新闻对国产车业界来说可能很重要，然而对我来说真正瞠目结舌的是比亚迪总裁王传福在这个新闻发布会上的讲话，简直是石破天惊！因为他第一次正式宣布即将在2009年发布纯电动商品车！
　　
　　
　　
　　这篇讲话绝对值得好好研读，如果华尔街日报明天不报道，那么只有两种可能：或者是比亚迪说话没有可信性，或者是华尔街日报反应迟钝。
　　
　　我关注比亚迪已经很久了，就是因为这个电动汽车。这个公司在电池方面的地位毋庸置疑，全世界三分之一的手机电池是他们生产的。而且几年以前比亚迪就宣称拥有大容量动力电池的最领先技术，我记得当时在网上贴出了他们电池的各项技术指标，远远领先于国外。电动汽车是个非常非常困难的技术，很多人认为完全靠充电电池根本不可能实用化。丰田出了个混合动力的 Prius，已经是风头浪尖。
　　
　　比亚迪的电动汽车是一波三折，很容易被认为是忽悠。他们曾经宣布2004年要在深圳投入200辆锂离子电池的纯电动汽车作为出租车，结果未能实现。这样的事情不用多你再说话别人可能就不信了。
　　
　　不过2006年的北京车展上比亚迪真的推出了一个纯电动汽车，F3e。此后不久有了关于这辆车的详细介绍，比亚迪内部甚至已经有了专门的充电站。甚至接受了媒体试驾。
　　
　　这个车的关键技术是使用了铁电池。锂电池的弱点是不安全，容易爆炸，而铁电池，具王传福说，他们的车可以直接扔到火里都不会爆炸。其他作为一辆能用的车的关键指标大约如下：
　　- 最大时速可能达到150公里。
　　- 充一次电最大续航300公里，一说是400公里。
　　- 充电站快速充电，10分钟之内可以充满70%，而晚上可以在家中过夜慢慢用普通交流电源充电。
　　这就足够用了。
　　
　　如果不谈电动汽车，比亚迪在传统动力汽车方面的成绩也很不错，也算国产汽车界自主创新的主力。
　　
　　跟奇瑞相比，比亚迪最大的优势是有钱。其资金无比充足，几乎想干什么马上就能干。
　　
　　我曾经鼓吹过魅族取代苹果，结果很多人质疑。现在比亚迪的目标是2015年中国第一，2025年世界第一。一个大国真正的崛起是要有几件东西的，不管比亚迪是不是忽悠，中国绝对需要这样的企业！如果2025年比亚迪真的成了世界第一汽车企业，我认为也没必要感到不可思议。第一强国当然要有第一企业。
　　
　　不相信比亚迪的人一定是受过教育的人。相信比亚迪的人有两种，一种是单纯善良的人，一种是目光远大敢想敢干的人，这两种人都不错。

2这个所谓铁电池应该还是锂电池吧，只不过用了磷酸铁锂 夜月空山 2008-10-11 21:57:21

2比亚迪本月销量全国第七，超越奇瑞和吉利 新长城 2008-10-11 15:00:15
F0刚上市就破万，猛

3情况是这样的 1 hansens 2008-10-12 19:14:37
比亚迪新发布一款F0 新车，这个车9月向各经销商铺货。所以批发数量一个月上万台。
但是真实的销售数据，要到10月才可能出来。
汽车工业协会的数据是批发数据，和实际零售有差距的。

410月份结果出来了 新长城 2008-11-06 17:47:09
7000多辆，比QQ少一些，但还是不错了。而且我觉得，上个月奇瑞被压过，这个月奇瑞肯定有些铺货的嫌疑。

比亚迪这个月排第八，仅次于奇瑞，差一千辆。我倒不纳闷比亚迪为什么可以做的这么好，但很纳闷奇瑞为什么表现这么差，连A3也不过卖了两千多辆而已。

5奇瑞一些深层次的矛盾开始暴露了. wolfgan 2008-11-06 18:00:59
这些问题如果不解决,奇瑞走不了多远.

3应该是byd吹嘘的 songcla 2008-10-11 17:01:55
f0问题很多，没有性价比。

4汽车工业协会的官方数据 新长城 2008-10-12 04:52:32
但我也觉得可能是分摊给经销商导致的

4估计吹牛居多.奇瑞和吉利的先发优势不是那么好捍动的. wolfgan 2008-10-11 19:08:02

2希望是真的，不过总让人想起水变油的魔术 肉猫 2008-09-30 00:56:44
当年的水变油也风光过，到后来只不过是一个魔术！

希望比亚迪玩的是真的~~~ 那可就是第四次产业革命了！





感觉还是够呛！

2这个这个,如果是真的,可以称之为革命了 R是Q后面的那 2008-09-29 04:07:26

3说明比亚迪的前景应该还是可以的 norly 2008-09-30 03:34:24
这个电动车的疑虑大家都非常多，等正式产品出来后就好了，是骡子是马拉出来溜溜

2200千瓦的动力，太多了点吧 宏寺 2007-12-23 19:11:16
不知道BYD做这个车的定位是什么，目前看市场上已有的hybrid车都是经济型车，不怎么追求性能的。对应的纯汽油机车型，如果是4缸发动机一般动力在110马力上下，也就是70-80千瓦。他这一下子弄出来200千瓦，就是250马力以上，赶上6缸的发动机了。真要这么牛，倒是可以考虑搞个轻车身，说不定在赛场上一战扬名，也是很好的宣传。今年北美的印地赛车中有个用生物燃油的车得了冠军，就狠狠吸引了眼球。

2看看SMART CAR电动版的性能吧，这可是已在市场上的车子阿 ct 2007-08-20 04:05:46
We’d like to introduce you to a car that’s designed to bring a breath of fresh air to the streets: the refreshingly new smart electric vehicle – or smart ed, as we call it. It’s the natural product of smart’s unswerving commitment to the environment and innovation – not to mention fun. It isn’t available to buy just yet, but it isn’t a million miles off.                                                                                                                                        Think of a smart. Then think of an electric socket concealed behind what used to be the fuel cap. Picture the complete absence of exhaust fumes, so no CO2 emissions from the rear. Close your eyes and hear… no sound at all coming from the engine. Imagine no engine oil, no road tax, and no London congestion charge and you’ll start to get a sense of what really makes the new smart ed tick.                                                                                                                                                                                      Powered solely by electricity, and chargeable from any three-pin socket the smart ed can achieve the equivalent of 300 mpg – that amounts to a saving of up to 80% in fuel costs over the already highly economical smart fortwo. The ev can travel up to 72 miles between charges, which typically take around 8 hours for a full charge – ideal for charging at work between your morning and evening commutes. If your journey takes you into the capital, you will find free electricity provided by some London boroughs, as well as free or discounted parking. With a top-up charge during the day, the smart ed’s daily range weighs in at 100 miles.                                                                                                                                                                                                                                 With that in mind, we’re running a market trial with selected blue chip companies who are happy to meet our requirements to power the cars using only renewable energy sources. When we say zero emissions, we really mean it! Among the partners already enrolled in the trial are The Energy Saving Trust, Islington and Coventry Councils, Foster & Partners, CarbonNeutral Company, EDF Energy and Amey.                                                                                                                                                              What’s more, our ed hasn’t had to sacrifice any of the fortwo’s performance or class-leading equipment: expect the full complement of Mercedes-Benz safety features and a top speed of 70 mph courtesy of a powerful Zytek electric motor. Once it’s up to speed (0-30mph in an impressive 6.5 seconds) the ev uses its tiny weight gain to deliver an exciting and stable drive.                                                                                                                                                                                                                              So there you have it: a zero emission vehicle that is 100% smart; a car that will save money and the environment. Although the smart ed won’t be available to the public just yet, it’s definitely something we’re working on. What’s more, towards the end of 2007, customers will be able to try it out at Mercedes-Benz World, Brooklands. We’ll be interested to hear what you think.

2【文摘】Paper battery ct 2007-08-14 04:29:20
Paper battery offers future power  

The black piece of paper can power a small light
Flexible paper batteries could meet the energy demands of the next generation of gadgets, says a team of researchers.
They have produced a sample slightly larger than a postage stamp that can release about 2.3 volts, enough to illuminate a small light.

But the ambition is to produce reams of paper that could one day power a car.

Professor Robert Linhardt, of the Rensselaer Polytechnic Institute, said the paper battery was a glimpse into the future of power storage.

The team behind the versatile paper, which stores energy like a conventional battery, says it can also double as a capacitor capable of releasing sudden energy bursts for high-power applications.

While a conventional battery contains a number of separate components, the paper battery integrates all of the battery components in a single structure, making it more energy efficient.

Integrated devices

The research appears in the Proceedings of the National Academy of Sciences (PNAS).

"Think of all the disadvantages of an old TV set with tubes," said Professor Linhardt, from the New York-based institute, who co-authored a report into the technology.

"The warm up time, power loss, component malfunction; you don't get those problems with integrated devices. When you transfer power from one component to another you lose energy. But you lose less energy in an integrated device."

  You can implant a piece of paper in the body and blood would serve as an electrolyte

Professor Robert Linhardt

The battery contains carbon nanotubes, each about one millionth of a centimetre thick, which act as an electrode. The nanotubes are embedded in a sheet of paper soaked in ionic liquid electrolytes, which conduct the electricity.

The flexible battery can function even if it is rolled up, folded or cut.

Although the power output is currently modest, Professor Linhardt said that increasing the output should be easy.

"If we stack 500 sheets together in a ream, that's 500 times the voltage. If we rip the paper in half we cut power by 50%. So we can control the power and voltage issue."

Because the battery consists mainly of paper and carbon, it could be used to power pacemakers within the body where conventional batteries pose a toxic threat.

"I wouldn't want the ionic liquid electrolytes in my body, but it works without them," said Professor Linhardt. "You can implant a piece of paper in the body and blood would serve as an electrolyte."

But Professor Daniel Sperling at University of California, Davis, an expert on alternative power sources for transport, is unconvinced.

'More difficult'

"Batteries and capacitors are being steadily improved, but electricity storage is much more difficult and expensive than liquid fuels and probably will be so forever," he said.

"The world is not going to change as a result of this new invention any time soon."

Professor Linhardt admitted that the new battery is still some way from the commercial market.

"The devices we're making are only a few inches across. We would have to scale up to sheets of newspaper size to make it commercially viable," he said. But at that scale, the voltage could be large enough to power a car, he said.

However, carbon nanotubes are very expensive, and batteries large enough to power a car are unlikely to be cost effective.

"I'm a strong enthusiast of electric vehicles, but it is going to take time to bring the costs down," said Professor Sperling.

But Professor Linhardt said integrated devices, like the paper battery, were the direction the world was moving.

"They are ultimately easier to manufacture, more environmentally friendly and usable in a wide range of devices," he said.

The ambition is to produce the paper battery using a newspaper-type roller printer.
