對于當(dāng)前的汽車的電動化進程，了解越多越知道差距。很多事情是不能比的，越比呢越發(fā)現(xiàn)是沒啥前途的，特別是在國內(nèi)你只能看到一個產(chǎn)品，只有寥寥無幾的參數(shù)，費了很大勁一層層剖析開來，才能發(fā)現(xiàn)其本質(zhì)是你料想不到的。在此無疑詆毀“產(chǎn)學(xué)研”的方針和計劃，只是覺得將源頭的科研成果籠罩在一層迷霧里頭似乎并不是很明智。 從美國的一個“先進車輛”計劃來看看其脈絡(luò)倒是作為參照的最好途徑。FreedomCAR（自由合作汽車研究）是整個計劃的代稱，各位是無法從 google得到相關(guān)的信息的，因為會被重置。這個計劃是由美國能源部（DOE）和美國的汽車研究會（SAE）在2002年1月宣布新的合作研究工作。其涉足的領(lǐng)域包括： Advanced combustion and emission control Batteries/electrochemical energy storage 此計劃分為三個大的方向: 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) 子項目其實劃分成了6個方向，所有的文件都是按照這個原則進行研發(fā)的。 1.novel traction motor designs that result in increased power density and lower cost; 牽引電機 2.inverter technologies involving new topologies to achieve higher efficiency, with the ability to accommodate higher temperature environments while achieving high reliability; 逆變器 3. converter concepts that use methods of reducing the component count and integrating functionality to decrease size, weight, and cost; 轉(zhuǎn)換器 4. new onboard battery charging concepts that result in decreased cost and size; 充電機 5. more effective thermal control through innovative packaging technologies; 散熱方案 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 在其計劃中，基本每年都會出一些報告： 總的報告：
2010200920082007200620052004200320022001
Electric Propulsion 20102009200820072006200520042003200220012000 仔細看這些報告，就會發(fā)現(xiàn)很有意思的東西在里頭，以2010年的Electric Propulsion報告為例： 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 從這些內(nèi)容中，我們可以看到其： Objectives XXX Approach XXX Major Accomplishments XXX Future Direction XXX Technical Discussion XXX 在這些之后，以項目概覽的方式，將其設(shè)計的結(jié)果整理出來，我們比較容易看到他們在做什么，從本質(zhì)而言，這樣的一個計劃可以使得GM和Ford汽車公司（悲劇的克萊斯勒把新能源部分給賣了）不用重復(fù)做著相同的工作，更多而言，研究的這些東西和結(jié)果將成為未來實際產(chǎn)品的堅實基礎(chǔ)。你可以清晰的看出，從02 年以來，每年這些研究在做什么，有什么成就，未來的方向。 與之對比，我們自己能看到什么？ |
