SAE New Energy Vehicle Forum: China’s focus on NEVs may have profound impact on future of transportation
November 13, 2013
China has a number of critical economic and environmental imperatives driving its pursuit of vehicle electrification, said the roster of plenary speakers at the SAE 2013 New Energy Vehicle Forum held in Shanghai this week. These include the increasingly problematic pollution and haze in cities; China’s projected increased reliance on imported oil; the need for rationalized multimodal transportation systems in ever more congested and space-limited cities; the growing dominance of the China auto market; and the desire to have China become the leader in the next generation of automotive technology, vehicles and mobility systems.
The shift from fossil fuels to electricity—while held in common with other countries—will be based on the “specific situation” in China, making the best use of China’s own advantages and innovations, but also with international cooperation, said Dr. Zhixin Wu, Vice President of the China Automotive Technology and Research Center (CATARC). The details of that specific situation may result in an electric vehicle parc somewhat different than in Western countries, other speakers noted, and may indeed—given the obvious scale of the China market—herald a major transformation in transportation, including the type and role of personal vehicles, others suggested.

New high-temperature ceramic capacitor could reduce cooling needs in power electronics for hybrids and EVs
August 02, 2013
Scientists from the National Physical Laboratory (NPL) in the UK have developed a new lead-free, high-temperature ceramic capacitor that could improve the efficiency and reliability of electric and hybrid vehicles.
Hybrid and electric vehicles rely on high efficiency power conversion and management, with automotive power electronics representing an emerging £40-billion (US$61-billion) global market, NPL noted. The power electronics found in vehicles today require cooling because of limitations in the temperature rating of components such as capacitors, which are used to store electrical energy. This is a disadvantage as the extra cooling systems add weight to the vehicles, reducing efficiency and reliability.
