本周早些时候,一辆高速行驶的Model S碰到了一大块金属物体,导致车辆严重受损。在事故发生地点附近的路面上发现了一块从半挂车上掉落的曲面物体,在场的道路工作人员称,该物体似乎是事故元凶。在进入车底时,该物体的几何形状产生了很大的杠杆作用,向上冲击,以类似25吨的峰力穿透了Model S。这个数量级的力足以在保护车底的四分之一英寸厚护甲板上打穿一个直径三英寸的洞。

这辆Model S的车主按仪表板提示系统的指示,将车停在路边,安全离车并撤离高速公路。碰撞引致车辆前部的电池组着火——电池组共有16个模块——但是电池组内部的防火墙将火情限制在车身前部。电池组内部的通道将火苗向下引导到道路上,而不是燃向车身。

消防人员赶到现场时,他们遵守标准程序,在保护电池的金属板上方打洞,向内喷水,以便阻断火源。对Model S的锂离子电池来说,用水灭火(相比于使用干粉灭火器)是正确的做法,但是不应穿破金属防火墙,因为新打穿的孔洞将使得火焰从那里向上进入Model S的前行李厢。尽管如此,水和干粉灭火器联合作用还是很快降火熄灭。

需要指出的是,电池发生的火情,被电池组架构中内置的防火墙阻隔在车身前面的一小部分空间内。火情根本没有进入乘员空间。

After a careful examination, we have concluded that some Model S vehicles manufactured between May 10, 2013 and June 8, 2013 may contain a defect. Specifically, the attachment strength of the mounting bracket for the left hand latch of the second row seat could be weaker than intended. This reduces our confidence that the left hand seat back will be properly retained in the event of a crash.

On February 26, at an event hosted by Secretary of Energy Steven Chu, Elon Musk announced Tesla will pay off our Department of Energy (DOE) loan five years early, twice as fast as required by the original 2010 loan agreement signed by Tesla and the DOE.

There are reasons why Tesla is pursuing a company owned store and service center model that we feel are really important. In many respects, it would be easier to pursue the traditional franchise dealership model, as we could save a lot of money on construction and gain widespread distribution overnight. Many smart people have argued over the years that we should do this, just like every other manufacturer in the United States, so why have I insisted that we take a unique path?

GASOLINE vs ELECTRIC

Now that our financing round is complete, I would like to clear up some misconceptions that arose last week as a result of our filing a public market financial prospectus. SEC rules rightly limit interaction with the press during a financing round to prevent companies from promoting stock. Unfortunately, this made it difficult for me to respond properly when some journalists gained the wrong impression.

Almost one month ago to the day we announced one of the biggest milestones in Tesla’s history…our first customer deliveries of Model S. Over the past four weeks we have enjoyed welcoming you into the birthplace of Model S and sharing with you a collection of images highlighting each segment of the Model S manufacturing process. This week we share with you the final video of our Inside Tesla series. Watch as we infuse soul into your Model S on the Final Assembly line.
