原创 系统工程的渐进

    对于当前的汽车的电动化进程，了解越多越知道差距。很多事情是不能比的，越比呢越发现是没啥前途的，特别是在国内你只能看到一个产品，只有寥寥无几的参数，费了很大劲一层层剖析开来，才能发现其本质是你料想不到的。在此无疑诋毁“产学研”的方针和计划，只是觉得将源头的科研成果笼罩在一层迷雾里头似乎并不是很明智。

    从美国的一个“先进车辆”计划来看看其脉络倒是作为参照的最好途径。FreedomCAR（自由合作汽车研究）是整个计划的代称，各位是无法从google得到相关的信息的，因为会被重置。这个计划是由美国能源部（DOE）和美国的汽车研究会（SAE）在2002年1月宣布新的合作研究工作。其涉足的领域包括：

Advanced combustion and emission control

Batteries/electrochemical energy storage

此计划分为三个大的方向:

1.Advanced Battery Development, System Analysis, and Testing 

2.Applied Battery Research (ABR) 

3.Focused Fundamental Research, or Batteries for Advanced Transportation Technologies (BATT)

Electric propulsion systems (e.g., power electronics, electric motors)

=>Advanced Power Electronics and Electric Machines (APEEM)

子项目其实划分成了6个方向，所有的文件都是按照这个原则进行研发的。

1.novel traction motor designs that result in increased power density and lower cost; 

牵引电机

2.inverter technologies involving new topologies to achieve higher efficiency, with the ability to accommodate higher temperature environments while achieving high reliability;

逆变器 

3. converter concepts that use methods of reducing the component count and integrating functionality to decrease size, weight, and cost; 

转换器

4. new onboard battery charging concepts that result in decreased cost and size;

充电机

5. more effective thermal control through innovative packaging technologies; 

散热方案

6. integrated motor/inverter concepts.

集成方案

Fuel cell power systems

Materials technologies (e.g., for lightweighting)

Vehicle systems and analysis

Vehicle-to-electricity grid interaction

On-board hydrogen storage

Hydrogen production and delivery

Hydrogen codes and standards

从这些内容中，我们可以看到其：

Objectives XXX Approach XXX Major Accomplishments XXX Future Direction XXX Technical Discussion XXX

   在这些之后，以项目概览的方式，将其设计的结果整理出来，我们比较容易看到他们在做什么，从本质而言，这样的一个计划可以使得GM和Ford汽车公司（悲剧的克莱斯勒把新能源部分给卖了）不用重复做着相同的工作，更多而言，研究的这些东西和结果将成为未来实际产品的坚实基础。你可以清晰的看出，从02年以来，每年这些研究在做什么，有什么成就，未来的方向。

   与之对比，我们自己能看到什么？

PS：EDN的博客系统有多不友善和糟糕呢？当我把以上的所有目录，从TXT文件中剪切出来，还需要每个分行的地方进行手工的回车然后用Backspace以免其出现不必要的空格，才能把它分开，在博客编辑系统中和最后的结果中，它呈现出截然不同的状态……
