The myth of the “long tailpipe” – the idea that, because EVs are partially powered by dirty coal, they are no cleaner than legacy vehicles – just won’t go away. In 2012, a detailed study from the Union of Concerned Scientists found that even if it were charged 100% from coal, an EV would still… Read more »

BMW takes steps to ensure more responsible production of cobalt
And the dirty little secret of EVs is…cobalt. The metallic element is used in significant quantities in EV batteries. Unfortunately, about half the world’s cobalt comes from the Democratic Republic of Congo (DRC), a war-torn land in which working conditions are bad, and child labor is common. In 2014, as many as 40,000 children worked… Read more »
Ricardo to integrate 800 V electric powertrain for Fisker EMotion
Fisker has selected global engineering firm Ricardo to integrate the electric powertrain for the upcoming Fisker EMotion. The partnership will include integration of Fisker’s proprietary charger, battery pack and e-axle systems. The EMotion powertrain, including the motors, inverters and power electronics, is based on an 800 V architecture, which, according to Fisker, delivers many benefits,… Read more »
Korean battery-makers to introduce NCM 811 cells
There’s a new battery cell in town, and everybody’s talking about its better energy density and lower costs. South Korean cell maker SK Innovation recently announced that its new NCM 811 cells would be available in December for stationary storage systems, and in the third quarter of 2018 for EVs. SK’s current cells use an… Read more »

PowerFlex says its Adaptive Load Management is the best technology to balance EV charging loads
“This is the first truly new consumer device to be introduced in almost twenty years,” says Forest Williams, Director of Business and Channel Development at PowerFlex Systems. “Certainly this product will have the biggest impact on electrical systems and the grid since the advent of television in the 1950s.” Williams is referring, of course, to… Read more »
GKN Driveline new eTwinsterX offers compactness, efficiency and torque vectoring
GKN Driveline’s eAxles integrate an electric motor and a two-speed transmission in a single compact unit. This not only makes it easier to fit an eDrive unit within a vehicle chassis, but also improves efficiency on vehicle assembly lines. GKN supplies front eAxles for the Porsche 918 Spyder and BMW i8, as well as rear… Read more »
Volvo receives largest-ever order of electric buses for Trondheim, Norway
Transit operator Tide Buss has placed an order for 25 Volvo 7900 Electric buses for the city of Trondheim, Norway, Volvo’s largest-ever order of fully electric buses. Trondheim’s transit agency, AtB, was among the first in Europe to order hybrid buses from Volvo in 2010. The new acquisition will bring Trondheim’s fleet of electric buses… Read more »
GKN’s new EV driveline is compact, efficient and adaptable
GKN Driveline’s new eTwinsterX system is designed to be adaptable to any vehicle type, from small electric city cars to plug-in luxury SUVs to electric hypercars, in front-wheel, rear-wheel or all-wheel drive configurations. GKN says the new eTwinsterX axle offers three advantages over competing electric drivelines. Its coaxial format is significantly smaller than other systems… Read more »
New study: V2G may not degrade EV battery life – it might actually extend it
Vehicle-to-grid (V2G) technology could turn the challenge of EVs’ power consumption into an opportunity, allowing vehicle batteries to help balance electrical grids and facilitate the use of renewable energy. Alas, a recent study from the University of Hawaii suggested that the additional cycling could harm battery performance. Now a study from the University of Warwick… Read more »
