Berkeley Lab study suggests subsurface structures responsible for dendrite formation with Li metal anodes

Green Car Congress

Researchers at Lawrence Berkeley National Laboratory have shed new light on the formation of dendrites in high energy density rechargeable batteries with lithium metal anodes. The electrodes in today’s lithium ion batteries are porous, and about 30 vol% of the electrode is taken up by inactive phases. Source: Harry et al.

UPS-led SEUL consortium switches on smart-grid fleet charging solution in London; maxing out on EVs without expensive grid upgrades

Green Car Congress

A UPS-led consortium has deployed new smart-grid charging technology in London that overcomes the challenge of simultaneously recharging an entire fleet of electric vehicles (EVs) without the need for the expensive upgrade to the power supply grid. A key part of this initiative is the use of onsite energy storage batteries.

ICCT/TNO study: Real-world vehicle fuel consumption discrepancy widens to 42% in Europe

Green Car Congress

Since 2001, the discrepancy between official measurements of vehicle efficiency and actual performance of new cars in everyday driving has more than quadrupled—a discrepancy that translates into €450 per year in extra fuel costs for the average vehicle. for selected brands in 2001 and 2015.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

In 2001, a team of engineers at a then-obscure R&D company called AC Propulsion quietly began a groundbreaking experiment. It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid.
