Updated 8/18/2014 11:45 AM EST to include pricing details. It seems Tesla’s not the only company building EVs in Silicon Valley these days. Campbell-based Renovo Motors, which has operated in “stealth mode” for four years, has just taken the wraps off its new electric supercar. The Renovo Coupe is an electrified version of the classic… Read more »

New report: Wide bandgap technology can make power conversion 90% more efficient
Wide Bandgap (WBG) semiconductor technologies are attracting a lot of attention, and research funding. In January, the Obama administration selected a consortium of businesses and universities to lead an innovation institute focused on WBG materials. Japan and the UK are also funding R&D in the field. A new report from Lux Research, Silicon vs. WBG:… Read more »
CD-adapco’s new set of battery simulation tools
CD-adapco has developed a set of Li-ion battery simulation tools designed to enable faster design and development of EV power systems. The new technology is available within CD-adapco’s flagship software package STAR-CCM+ and the application-specific Battery Design Studio. The new software tools were developed as part of the DOE’s Computer Aided Engineering of Electric Drive Batteries… Read more »
Brookhaven scientists gain new insight into why fast charging reduces battery capacity
Using a new method to track the electrochemical reactions in a battery, scientists at the DOE’s Brookhaven National Laboratory have gained new insight into why fast charging inhibits performance. The results, published in Nature Communications, could help battery makers to optimize materials for faster-charging batteries. “Our work was focused on developing a method to track… Read more »
It’s official: Panasonic will make major investment in Tesla’s Gigafactory (Updated)
Originally posted 7/29/2014 Panasonic has reached a basic agreement to participate in Tesla’s Gigafactory. The battery-maker will likely invest 20-30 billion yen ($194-291 million) initially, according to Nikkei. Tesla plans to start construction this fiscal year, and to begin producing battery cells in 2017. The Californians will foot the bill for the land and buildings, and… Read more »
New model predicts carbon components’ performance as electrodes
Researchers at Rice University and Lawrence Livermore National Laboratory have developed a new theoretical model that predicts how carbon components will perform as electrodes. The research, published in the journal Physical Review Letters, examined the electronic characteristics of anode materials, including quantum capacitance (the ability of a material to absorb charge) and absolute Fermi level… Read more »
BMW and Samsung expand supply agreement for battery cells
BMW and Samsung SDI plan to expand their supply relationship for EV battery cells. The two companies have signed a memorandum of understanding that includes an increase in quantities delivered as well as further technological development of battery cells. BMW produces high-voltage batteries for the i3, i8 and other future hybrid vehicles at its plant… Read more »
Q&A with Ian Wright: The CEO of Wrightspeed on Tesla, gas turbines and electric trucks
Ian Wright is originally from New Zealand. He came to California in 1993, where he happened to be a neighbor of Tesla founder Martin Eberhard. He worked with optical switching systems at a company called Altamar Networks until it went out of business, then decided he wanted to start his own company. Eberhard and his… Read more »
A closer look at the semiconductor switch
In this article I’ll be giving an overview of that most important of power electronics components: the semiconductor switch. I’ll first address what a switch is, and then delve into some of the more important compromises and shortcomings that exist in real-world switches that engineers must contend with when designing chargers, motor controllers, DC-DC converters… Read more »
Tesla battery swapping: dead, or just delayed?
It was one year ago that Tesla introduced its battery swapping technology in a theatrical presentation, with lights flashing and music thumping. At the time, Elon Musk said that the company planned to make swapping available as soon as the end of 2013, and eventually install the capability at every Supercharger station. In early 2014… Read more »
