最近没有时刻看一些技能文档,就把曾经重视的东西写下来,并把上一篇文章ORNL关于无线充电的资料补完,等自己也有些时刻静下心来把电动轿车与智能电网交互的故事写写清楚。
这个开端的构思是从2007年的《AdvAnced Power electronics And electric MAchinery ProgrAM》的年报之中的《Utilizing the Traction Drive Power Electronics System to Provide Plug-in Capability for HEVs》开端的,2008年《Using the Traction Drive Power Electronics System to Provide Plug-in Capability for Hybrid Electric Vehicles (HEVs)》和2009《Using the Traction Drive Power Electronics System to Provide Plug-In Capability for Hybrid Electric Vehicles》年均有这个项目的文章存在。
更风趣的是在前面文章中介绍过的文章《Converter Topologies for Wired and Wireless Battery Chargers》之中有着3年的方案。
FY11 objectives
Complete the circuit simulation study of converter candidates for an integrated wired charger
Produce a conceptual design for a 5 kW prototype by incorporating the simulation results on component requirements and performance data
FY12 objectives
Finalize design, build, and test a 5 kW integrated wired charger prototype
FY13 objectives
Refine the integrated wired charger design to improve power density by developing custom switch modules and high density converter packaging technologies
FY14 objectives
Refine the wireless charger prototype design to further performance improvements by incorporating advanced packaging technologies
如果把07,08和09也进行罗列的话:
Objectives for FY 2007
— prove the concepts by circuit simulation studies
— develop battery charging and mobile power generation control strategies, and
— develop a conceptual design of a 55-kW prototype traction drive with charging and generation functions.
Objectives for FY 2008 effort
– Design, fabricate, and test an HEV power electronics system prototype comprised of a 55 kW
motor inverter and a 30 kW generator inverter to evaluate its battery charging capability.
– Characterize charging performance in terms of efficiency, power factor, and grid current
harmonic distortion factor.
Objectives for FY 2009 effort
—Modify and test the hybrid electric vehicle (HEV) power electronics system prototype consisting of a 55 kW motor inverter and a 30 kW generator inverter to evaluate its mobile power generation capability.
—Characterize mobile power generation efficiency performance.
这个项目的整体构思对错常有意思的,在传统的HEV和PHEV体系之中,都是有一个引擎带动的发电机存在的,将电网的交流电导入该马达之中,能够尽可能的复用这个体系,比起添加一个单一的车载充电机而言,这无疑将直接下降成本和下降体系的复杂度:
这个项目在09年的测验作用十分有意思,以下是其发电功率曲线(一开端没看理解,作为一个充电机,这玩意首要完结的使命是把AC变成DC,这儿测验出来的竟然是输出AC,把我惊到了),以当时90%的要求来看,将来是能够运用在停电场合的。
细心翻了08年的,才发现08年现已将充电的功率整理出来了:
这样一个一体式的玩意,既完结AC=》DC,也一起能够完成DC=》AC,真的十分牛,也十分风趣。
