General Motors will bring all its electric vehicle battery pack building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its expanded battery assembly plant in Brownstown, Mich. A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem’s plant in Holland, Mich. The battery system weight of 474 lbs (215 kg)—86 pounds (39 kg) lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR. Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range. Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale. —Larry Nitz, executive director of GM global transmission and electrification engineering Battery module for 2015 Spark EV battery pack.

Range will remain at an EPA-rated 82 miles (132 km) and MPGe will remain at 119 (equivalent to 2.0 l/100 km). Priced at $19,995 with full federal incentives, Spark EV is currently on sale in California and Oregon. The 2015 Spark EV features technology including Siri Eyes Free, 4G LTE and DC Fast Charging. Brownstown Battery Assembly’s 479,000-square-foot, landfill-free facility south of Detroit also produces the lithium-ion battery packs for GM’s extended-range electric vehicles. It started mass production in October 2010 and is the first high-volume manufacturing site in the US operated by a major automaker for automotive lithium-ion battery production. The site was made possible with the help of American Recovery and Reinvestment Act funding through the US Department of Energy.
GM and Maplesoft to Collaborate on Electric Vehicle Technologies at the University of Waterloo Maplesoft October 15, 2010 A new five-year, $10.5-million partnership between General Motors of Canada, Waterloo-based Maplesoft Inc., and a multidisciplinary research team at the University of Waterloo is tackling the challenges of next generation electric vehicles. Through model-based design and prototype testing, the team will investigate crucial technologies for achieving more widespread use of electric vehicles. “Vehicle electrification is a key pillar of our energy diversification strategy,” said Kevin Williams, president and managing director of GM of Canada. “Building on our leading RD commitments in Canada, this project better positions us to exceed customers' expectations with respect to the performance, safety, and sustainability of our electric vehicle technologies.” The research is being supported by the Automotive Partnership Canada (APC) with the Natural Sciences and Engineering Research Council of Canada (NSERC) as the lead agency. APC is contributing $3.6 million, in addition to $2.5 million from the Ontario Research Fund. “The Harper government's continued commitment to RD in Canada is bringing long-term benefits to our automotive industry, and is helping to keep us on the cutting edge of innovation,” said Peter Braid, Member of Parliament for Kitchener-Waterloo, on behalf of The Honourable Tony Clement, Minister of Industry. “This technology is an exciting example of made-in-Canada innovation resulting from the Automotive Partnership Canada program." “We're very excited about the APC project,” added Dr. Tom Lee, Maplesoft's vice-president, engineering applications. “This project will result in powerful new software tools that will speed up the design and analysis of electric vehicles.” The development and validation of key enabling technologies such as vehicle stability control, power management systems, and battery monitoring and charging devices will be important focus areas for the research team, led by Dr. Amir Khajepour from the University of Waterloo. Importantly, the technologies originating from Waterloo will also be tested by GM vehicle development teams. Engaging the research team in the vehicle development process will provide them with a unique opportunity to gain insight into bringing new technology concepts to market, and help transform the research findings into a truly integrated technological solution. "Electrification of automotive systems presents complex challenges for a vehicle's powertrain, control systems, battery health monitoring, thermal management, and safety,” added Dr. Khajepour. “With the APC funding and the support of General Motors, we plan to tackle these challenges to develop the next generation of key electric vehicle technologies.” Maplesoft, a leading developer of high performance physical modeling and simulation software, will incorporate the researchers' innovative ideas into new design tools that GM's staff can apply during their routine engineering work. Maplesoft is particularly interested in using its modelling capabilities to help improve the batteries deployed in electric vehicles.

今天一大早就收到一个朋友转来的新闻。下面网页里面有照片。 新闻里面说偷窃的商业机密被用来和中国的汽车公司做交易。 这种事情似乎也不少见了。早先北大有个搞化学的海归也被查出偷窃杜邦的机密。这些也算是诚信问题。 http://abcnews.go.com/Business/wireStory?id=11227232 Ex-GM Worker, Husband Accused of Stealing Secrets Former GM employee, husband, indicted in alleged scheme to steal hybrid car secrets for profit The Associated Press By ED WHITE Associated Press Writer DETROIT July 22, 2010 (AP) A former General Motors engineer and her husband conspired to steal trade secrets about hybrid technology and use the information to make private deals with Chinese competitors, according to a federal indictment unsealed Thursday. Shanshan Du and Yu Qin, both of Troy, were indicted on conspiracy, fraud and other charges. They had been under scrutiny for years and were charged in 2006 with destroying documents sought by investigators, a case that was dropped while a broader probe was pursued. The indictment says Du, who was hired at GM in 2000, purposely sought a transfer in 2003 to get access to hybrid technology and began copying documents by the end of that year. In 2005, she copied thousands of documents, five days after getting a severance offer from the automaker, according to the indictment. By that summer, Qin was telling people he had a deal to provide hybrid technology to Chery Automobile, a GM competitor in China, the indictment says. The couple had set up their own company, Millennium Technology International. Outside court, Assistant U.S. Attorney Cathleen Corken said there's no indication the Chinese benefited. Du, 51, and Qin, 49, were arrested Thursday and remained mostly silent during a court appearance where they waived a reading of the indictment. Not-guilty pleas were entered for them. The maximum penalty if convicted is 20 years in prison. Theft of trade secrets is a threat to national security, Andrew Arena, head of the FBI in Detroit, said in a statement. Du's attorney, Robert Morgan, declined to comment. Qin's attorney, Frank Eaman, said he was completely surprised by the indictment. This investigation has been going on so long I figured if they had a basis they would have charged them a long time ago, Eaman said. Corken said GM learned about the alleged theft and called the FBI. GM estimates the value of the stolen information at $40 million. In May 2006, Du and Qin were charged with destroying records to stifle an investigation of them. FBI agents followed them to a major grocery store where Qin approached a Dumpster, according to a court filing at the time. Agents later retrieved shredded documents. That criminal complaint was dropped less than two months later, a common move when investigators want to further develop a case. The indictment includes an obstruction of justice charge against Qin for the alleged Dumpster incident. Du and Qin, both U.S. citizens, were released on bond and ordered to mostly stay in the Detroit area. 【Copyright 2010The Associated Press. All rights reserved.
