Researchers at the Helmholtz Institute Ulm (HIU) have developed a new lithium metal battery that they say offers an extremely high specific energy of 560 watt-hours per kilogram (Wh/kg) based on the total weight of the active materials. The team used a nickel-rich cathode that allows a large amount of energy to be stored, and… Read more »

Simplifying EV traction inverters emergency power supply architecture
The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »
Learn about next-generation BMS architectures for EVs
While the adoption of electromobility is rapidly increasing in our day-to-day life, the development of batteries and their Battery Management Systems (BMS) continues to be further optimized for safety, cost, manufacturing and other key parameters. NXP Semiconductors closely monitors the global xEV BMS trends and contributes to their evolution by tailoring devices for the upcoming… Read more »
Purdue researchers demonstrate liquid-to-vapor phase change cooling for EV charging cables
Faster EV charging will necessitate a significant increase in the current passing through the charging cable, which causes an increase in heat. Researchers at Purdue University may have developed a way to dissipate that heat. Their solution employs a liquid-to-vapor phase change. With traditional liquid cooling, the cooling fluid captures the heat and is routed… 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 »
SAE hires contractor team for EV charging security research project
SAE International has announced an agreement with a contractor team, comprised of Eonti, DigiCert and VerSprite, to perform technical development of the SAE EV Charging Public Key Infrastructure (PKI) project, an industry-led research project aimed at strengthening EV charging system security. The PKI project was launched in May 2020. With the contractor team onboard, technical… Read more »

Archer partners with Fiat Chrysler to develop electric VTOL aircraft
Palo Alto-based Archer has teamed up with Fiat Chrysler (FCA) to develop electric vertical takeoff and landing (eVTOL) aircraft, with the intent of starting production in 2023. FCA has already collaborated on cockpit design elements of Archer’s first aircraft, which is expected to be unveiled early this year. Archer’s goal is to create a vertically… Read more »
EV manufacturer Proterra to go public through merger with ArcLight Clean Transition
Proterra is best known as an electric transit bus OEM, but it has branched out into providing electric powertrain solutions to other vehicle manufacturers and turnkey charging and energy management solutions to fleets. The company has long been considered a likely candidate for a public share offering, and now it has announced that it will… Read more »
DERConnect will enable researchers to test integration of renewable energy and EV batteries into the power grid
The National Science Foundation has awarded $39 million to a team of engineers and computer scientists at the University of California San Diego to build a test bed to better understand how to integrate distributed energy sources and EV batteries into the power grid. “We will be replicating the entire California power grid on one… Read more »
