EV powertrains have to be tested during many development phases, and the system’s overall efficiency is a major contributor to consumer buying criteria. However, the measurement of electrical power consumed throughout the entire vehicle (powertrain, converters, HVAC system, BMS system, etc) as well as for the generation of mechanical power becomes an instrumentation challenge due… Read more »

LiNa and ion Ventures conclude successful test of solid-state sodium battery platform
ion Ventures, a utility and energy storage infrastructure specialist, and LiNa Energy, a solid-state battery technology developer, recently concluded a successful trial of LiNa’s proprietary solid-state sodium battery platform. LiNa says the battery is constructed from easily sourced, low-cost materials, contains no cobalt or lithium, operates at a wide range of temperatures, does not require… Read more »
MIT researchers describe new electrolyte to reduce metal electrode degradation
A team of researchers led by MIT Professor Ju Li has found an electrolyte that overcomes the problems associated with metal electrodes, which could result in batteries with longer lifespans and more energy storage capacity. The research was reported in the journal Nature Energy in a paper by Li and others. The researchers say the… Read more »
Biden’s EV plan includes $100 billion in purchase rebates and $15 billion for charging stations
Details of the Biden administration’s $174-billion proposal to boost EV adoption are slowly beginning to leak out. According to a Transportation Department email message seen by Reuters, the plan calls for $100 billion in new consumer rebates, $15 billion to build 500,000 new charging stations, $20 billion for electric school buses, $25 billion for zero-emission… Read more »
VW to enable bidirectional charging on all EVs on its MEB platform starting next year
Bidirectional charging is the technology of the hour. It enables vehicle-to-grid—or should we say, vehicle-to-anything (V2X)—applications, which promise to greatly facilitate the integration of EVs and renewable energy into the grid, to offer opportunities for fleets to offset their electrification costs, and to allow other handy capabilities, such as backup power. Now Volkswagen has given… Read more »
MIT researchers use semisolid electrode to prevent short circuits in lithium metal batteries
Researchers may have found ways to prevent dendrite formation in solid-state batteries. Their findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, MIT Professor Yet-Ming Chiang and researchers at MIT and other institutions. Chiang explained, “The only way you can reach the energy densities that are interesting… Read more »
New study says commercial truck electrification is within reach
It’s been a long haul for electric trucks—pilots have been going on for over a decade, but fleet operators are just beginning to put in serious orders. Battery costs are often cited as a barrier to faster adoption, but a new analysis concludes that a lack of appropriate policies around adoption incentives, charging infrastructure, and… Read more »

Challenges and benefits of moving from silicon to GaN in EV power electronics: WEBINAR
As vehicle electrification increases, so does the requirement of power semiconductors to provide highly efficient power conversion at increasingly higher switching frequency. A move from traditional Si to WBG, in particular Power GaN FETs, coupled with Cu clip-bonded package technology instead of traditional wire bonded D2 and TO packages can address the demands of electrification… Read more »
The US House’s Clean Future Act is loaded with pro-EV policies
The US House of Representatives is currently considering the CLEAN Future Act, “a comprehensive and ambitious plan to ensure the United States acts aggressively to tackle the climate crisis in the 2020s and achieves net-zero greenhouse gas (GHG) pollution by no later than 2050.” The targets, which include a 50% reduction in GHG emissions from… Read more »
