Sumitomo Electric’s new generation of SiC transistors offer low on-state resistance

Sumitomo Electric’s new V-groove superjunction transistors, which it developed through a joint research project with the National Institute of Advanced Industrial Science and Technology (AIST) use silicon carbide (SiC) semiconductors, and the company claims they offer the lowest on-state resistance yet achieved in an SiC transistor. Sumitomo has already developed V-groove MOSFETs that use a… Read more »

Mitsubishi Electric’s new energy-management system uses EVs to manage power generation

Mitsubishi Electric has developed an energy-management system capable of scheduling EV charging, discharging back into the grid, and optimizing the operation of PV and other power-generation systems according to the fluctuating unit price of electricity sold on the grid. A demonstration of the technology is underway at the company’s automotive factory in Changshu, China. The cost… Read more »

MIT wins $1.89-million DOE research grant for one-step electrochemical copper extraction from sulfur-based minerals

MIT Associate Professor of Metallurgy Antoine Allanore’s lab has received a nearly $2-million dollar grant to further develop copper collection methods from molten sulfur-based minerals using electricity. The resultant high-purity copper could be used in the production of high-quality wire used in growing markets like renewable energy and EVs. Current pyrometallurgy methods are tedious: sulfide… Read more »

Regenerative braking: A closer look at the methods and limits of regen

All motors are generators, the old saying goes, with the caveat that few types are equally good at both modes of operation, and some are downright awful as generators (a classic example being the single-phase shaded pole induction type, used in myriad small appliances the world over). Fortunately, both types of AC motor commonly used… Read more »

Mitsubishi Outlander PHEV delivers the goods

As a tree-hugging greenie, I tend to be prejudiced against SUVs, but after a week with the Mitsubishi Outlander PHEV, I couldn’t really find anything not to like. This medium-size crossover drives great, it’s comfortable, and it has all the high-tech goodies we’ve come to expect. The electric range of 22 miles is enough to… Read more »

CARB approves plan to invest $423 million from VW mitigation fund in zero-emission trucks, buses

The California Air Resources Board (CARB) has approved a plan to invest $423 million that the state will receive from the National VW Environmental Trust. The mitigation plan will invest primarily in zero-emission replacements for heavy-duty trucks, buses and equipment. There is also money to reduce emissions at freight facilities and marine projects, and for… Read more »

Costa Rican government deploys fleet of Mitsubishi plug-in vehicles

The government of Japan has delivered a fleet of 20 Mitsubishi Outlander PHEVs and 29 Mitsubishi i-MiEVs to the government of Costa Rica, as part of the Overseas Development Agreement between the two countries. The new vehicles will be used by 15 government agencies and universities. Costa Rica is a land of rugged terrain and… Read more »

Skeleton and Sumitomo partner to distribute graphene-based ultracapacitors

Ultracapacitor manufacturer Skeleton Technologies has signed a distribution agreement with Sumitomo Europe to provide energy storage solutions for the EV industry. Skeleton’s graphene-based ultracapacitors boast high power density, a recharge time of 2-3 seconds and more than one million life cycles. In EVs, ultracapacitors can be used in tandem with lithium-ion batteries, an arrangement that… Read more »

Yosemite National Park buys two Proterra electric buses

California’s Yosemite National Park has ordered two Proterra Catalyst electric buses. The world-famous tourist destination will be the first US National Park to add zero-emission buses to its permanent shuttle fleet. With more than five million visitors each year, Yosemite relies on its shuttle program to encourage park visitors to park once and use a… Read more »

MIT professor wins VW/BASF electrochemistry award for solid-state battery research

Dr. Jennifer Rupp, Assistant Professor of Materials Science and Engineering at MIT, has won the BASF and Volkswagen Science Award Electrochemistry 2017 for her outstanding research results in the area of next-generation energy storage systems. Dr. Rupp’s research focuses on material and electrode designs for solid-state batteries. She explored a novel glassy-type lithium-ion conductor that… Read more »
