Venture capitalists assume a large amount of risk when they invest in early-stage companies. They do so because of the potential for huge returns. To ensure that a portfolio of investments delivers the greatest return with the least risk, VCs spend a considerable amount of time evaluating companies, looking for the key ingredients of success….

Human-machine interface experts on the nuances of displaying and interacting with EV data
Few have been working on human-machine interface (HMI) design for EV drivetrains as long as Brian Gallagher and Kevin Coelho. In 2007, Gallagher joined the startup Aptera Motors as employee number three. Shortly after, Coelho joined him as the seventh addition to the California company, which was building ultra-efficient three-wheeled electric vehicles. Five years later,… Read more »
Samsung says it can immediately double capacity of Li-ion batteries
Samsung Electronics has developed a silicon carbide-free graphene coating that it says could immediately double the capacity of lithium-ion batteries. That would be an impressive feat indeed, considering that capacity has increased only twofold since Li-ion batteries were first commercialized in 1991. Many researchers are investigating the potential of silicon as an anode material, but… Read more »
ChargePoint’s new Express 100 24 kW DC fast charger
ChargePoint has introduced a new addition to its line of EV charging stations. The Express 100 is a compact 24 kW DC fast charger aimed at businesses such as retail locations, restaurants and convenience stores. Earlier this year, the company announced the Express 200, a 50 kW DC fast charger with a maximum charging rate… Read more »
FIA Formula E Championship aims to change perception and push EV technology to new heights
A race towards progress: The all-electric racing series The greatest obstacle to getting more EVs on the road isn’t high upfront costs, range anxiety or a lack of infrastructure – it’s simple consumer awareness. Despite the fact that the Model S, Volt and LEAF are becoming common sights in many cities, a surprisingly high number of… Read more »
ORNL breakthrough could enable wider application of graphene composites
Graphene, a two-dimensional hexagonal lattice of carbon atoms, has great potential in a number of EV-related applications, including anodes, lithium-sulfur batteries and ultracapacitors. With current technology, however, it’s impractical to use on a large scale, and researchers have been limited to using small flakes of the material. Now a team of researchers at the DOE’s… Read more »
New imaging technique displays the advantages of iron fluoride batteries
“Iron fluoride has the potential to triple the amount of energy a conventional lithium-ion battery can store,” says Song Jin, a Professor of Chemistry at the University of Wisconsin-Madison. “However, we have yet to tap its true potential.” Jin and his colleagues have been using a novel X-ray imaging technique to visualize and study the… Read more »
Real-time images of lithium dendrite structures could lead to better batteries
Scientists at the DOE’s Oak Ridge National Laboratory have captured the first real-time nanoscale images of lithium dendrite structures in lithium-ion batteries. The ORNL team is confident that its research, published in Nano Letters, will be of great benefit to scientists who are experimenting with different ways to tackle the dendrite problem. Dendrites form when… Read more »
Next-generation switched reluctance motor uses no rare earth elements
Ricardo has developed a new prototype 85 kW synchronous reluctance motor designed for EV applications. Most EV motors use permanent magnets made from materials such as neodymium-iron-boron and samarium-cobalt. However, the rare earth elements in these compounds can be expensive and problematic to obtain. Switched reluctance motors, which do not use permanent magnets, show great… Read more »
$30 million in Federal grants to pay for Proterra electric buses
The Federal Transit Administration FTA recently distributed $55 million in grants to 10 transit agencies as part of a program to deploy US-made electric transit buses. More than half of that money will be going to South Carolina-based Proterra, the Greenville News reported. Six transit agencies in five states will buy a total of 28… Read more »
