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 在其计划中，基本每年都会出一些报告： 总的报告：
2010200920082007200620052004200320022001
Electric Propulsion 20102009200820072006200520042003200220012000 仔细看这些报告，就会发现很有意思的东西在里头，以2010年的Electric Propulsion报告为例： 2.Power Electronics Research and Technology Development 2.1 Wide Bandgap Materials 2.2 Direct Water-Cooled Power Electronics Substrate Packaging 2.3 High Temperature, High Voltage Fully Integrated Gate Driver Circuit 2.4 Inverter Using Current Source Topology 2.5 A Segmented Drive Inverter Topology with a Small dc Bus Capacitor 2.6 Novel Packaging to Reduce Stray Inductance in Power Electronics 2.7 Air-Cooled Traction Drive Inverter 2.8.Power Device Packaging 2.9 Development, Test and Demonstration of a Cost- Effective, Compact, Light-Weight, and Scalable High Temperature Inverter for HEVs, PHEVs, and FCVs 2.10 High Dielectric Constant Capacitors for Power Electronic Systems 2.11 High Temperature Thin Film Polymer Dielectric Based Capacitors for HEV Power Electronic Systems 2.12 Glass Ceramic Dielectrics for DC Bus Capacitors 2.13 Development of SiC Large Tapered Crystal Growth 3.Electric Motor Research and Technology Development 3.1 A New Class of Switched Reluctance Motors Without Permanent Magnets 3.2 Novel Flux Coupling Machine Without Permanent Magnets 3.3 Permanent Magnet Development for Automotive Traction Motors 3.4 Scalable, Low-Cost, High Performance IPM Motor for Hybrid Vehicles 4.Systems Research and Technology Development 4.1 Benchmarking Competitive Technologies 4.2 High-Power-Density Integrated Traction Machine Drive 4.3 Advanced Integrated Electric Traction System 4.4 Small Business Innovative Research (SBIR) Projects 4.5 Technology and Market Intelligence Regarding 5.0 Thermal Management Research and Technology Development 5.1 Air-Cooling Technology for Power Electronics 5.2 Characterization and Development of Advanced Heat Transfer Technologies 5.3 Electric Motor Thermal Management 5.4 Power Electronics Thermal System Performance and Integration 5.5 Thermal Control of PHEV/EV Charging Systems 5.6 Thermal Performance and Reliability of Bonded Interfaces 5.7 Thermal Stress & Reliability for Advanced Power Electronics & Electric Machines 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？ |
