General Motors is turning heads this month—on the technical literature front, that is. The automaker is publishing 12 SAE International technical papers related to the 2011 Chevrolet Volt. SAE Publications experts believe the dozen papers received from a single source, in a single year, focused on a single topic, represent a milestone in the tech-paper realm.

It’s not uncommon for SAE International to publish multiple technical papers related to a single subject in any given year. This typically occurs when the industry is pushing hard to meet new regulatory mandates, such as those regarding emissions and occupant protection. In most cases, papers published on a single topic are submitted by a variety of sources—perhaps an OEM, a few suppliers, and a research university, for example.

But the dozen papers on Volt’s development and technologies were authored by GM engineers, and the effort coordinated and sanctioned by GM. The Volt papers are among 1250 new tech papers being published, as is SAE tradition, at the 2011 World Congress. (Go to http://papers.sae.org/.)

“It’s pretty safe to say that this hasn’t happened before, and I give kudos to GM,” said Colette Wright, Auto Sector Manager, SAE Engineering Events Development & Management.

The Volt-focused papers cover a broad range of topics, including the car’s aerodynamic development; the new 4ET50 electrified transaxle (two separate titles); Voltec battery design and manufacturing (three separate titles); high-voltage contactor control function; development of the car’s portable charge cord; 12-V stop-start system optimization; high-voltage power allocation management; EMC requirements and test methodologies; and co-development with Goodyear of the Volt’s low-rolling-resistance/multi-capability tires.

The papers came as no surprise to AEI editors. About halfway through Volt’s 48-month development, GM engineers alerted us to expect a “flurry” of SAE tech papers related to various facets of the new extended-range electric vehicle.

“We’re extremely proud of what we’ve achieved in this vehicle,” said Pete Savagian, GM’s Director of Hybrid and EV Powertrain Engineering, and Electric Motor Release. “We decided pretty early in the program that we’d go heavy on getting much of our learnings out into the industry, publishing it through SAE."

GM and Ford are each publishing 38 tech papers at this year’s SAE World Congress, more than other automakers, according to Erin Moore, SAE’s Product Manager, Technical Papers. GM has applied for more than 100 patents for Volt-related technologies.

Volt沃蓝达 通用汽车 。2010年，雪佛兰旗下增程型电动车Volt沃蓝达在美国已率先上
市，中国作为通用汽车在全球的重要市场之一，今年底，也将正式引进这款电动车，成
为美国本土之外首个引进Volt车型的地区之一。


在汽油发动机不启动，即零油耗、零排放的纯电动行驶情况下，沃蓝达的续航里程能够
达到60km以上，对于应付每天上下班的路程来说，大部分人都够用了，这样的话每天跑
一个往返，晚上就可以在家充电。



　　对于需要跑长途的人们来说，也丝毫不用担心，当16千瓦时的车载电池电量下降到
最低临界限值时，1.4L排量的汽油发动机将会自动启动发电，继续驱动车辆行驶，累积
起来，沃蓝达的总行驶里程最长可以达到570km，丝毫不输于传统的汽油发动机驱动车
辆。

在常规的车辆后部汽油加油口之外，在车头驾驶员侧设置了充电插口。通过家用的标准
220V电路可以直接为车载T型锂离子电池组充电，无需到专门的充电站即可完成充电操
作，充满电约需5个小时，比以往的很多电动车更加方便快捷。


　在需要大动力输出以完成再加速或超车动作时，只需加大油门，你会发现电动机驱动
能时时带来大扭矩输出的优势。根据官方资料显示，沃蓝达的百公里加速时间不足
10s，而最高时速可以达到160km/h，比很多电动车都强了不少。


比亚迪为啥不搞个类似的

这玩意的整个powertrain设计还是很有才的...
