一体化充电机 - 汽车电子 - 电子工程

最近没有时间看一些技术文档,就把以前关注的东西写下来,并把上一篇文章ORNL关于无线充电的材料补完,等自己也有些时间静下心来把电动汽车与智能电交互的故事写写清楚。

这个最初的构思是从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》开始的,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。

更有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年的计划。

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.

这个项目的总体构思是非常有意思的,在传统的HEV和PHEV系统之中,都是有一个引擎带动的发电机存在的,将电的交流电导入该马达之中,可以尽可能的复用这个系统,比起增加一个单一的车载充电机而言,这无疑将直接降低成本和降低系统的复杂度:
