Bee pollen forms carbon microstructures for Li-ion anodes
Much research in the battery world focuses on finding a replacement for graphite as an anode material. One candidate is hard carbon, which can be formed in various morphologies to deliver the desired properties. But in fact, there are already millions of tiny factories around the world, cranking out as many carbon particles as could… Read more »
The next nifty EV feature: perpendicular steering
Add another item to the list of neat tricks that cars will soon be learning: the ability to maneuver sideways in order to slip into tight parking spaces. The OmniSteer project, funded by Germany’s Ministry of Education and Research, aims to develop a vehicle with “a lateral and transverse guidance system capable of performing orthogonal,… Read more »
TurboDock: AeroVironment’s answer for affordable and elegant workplace charging

Advancing BMS: Linear Technology launches its fourth-generation battery stack monitor
Engineers use battery management systems (BMS) to prevent problems that occur in Li-ion batteries when they are over-charged or over-discharged, including premature capacity loss and thermal events. A BMS ensures precise control and keeps the individual cells balanced, which is critical to extracting the most useful energy from a pack. Fortunately for EV systems designers,… Read more »
EV Fleet CEO on building a highway-capable light-duty all-electric truck
There are a lot of great opportunities for companies building EVs for niche markets, but getting an independent automotive startup off the ground is anything but easy. EVs can be very practical from a financial point of view. So it’s a bit of a shame that for the world’s most practical vehicle buyer – the… Read more »
