GM and Fiat Chrysler hit with lawsuits over diesel cheating software
We may not have heard the last of the dirty diesel scandal. Two of the Big Three automakers have recently been served with lawsuits alleging behavior similar to that which may end up costing VW $20 billion. The US Justice Department has filed a civil complaint on behalf of the EPA, claiming that Fiat Chrysler… Read more »
No more small pilots: It’s time to convert US transit buses to electric
City buses are an ideal application for EVs. The savings on fuel and maintenance are undeniable. In China, cities are ordering them by the thousand. So why are US cities still piddling around with pilots of a few buses? “The time for pilot programs should be in the rear-view mirror,” writes Gina Coplon-Newfield, Director of… Read more »

Open source hardware platform lets anyone build an EV
Thanks to the internet (for better or for worse), anyone can publish their own book or magazine. What if anyone could build their own car? That’s the idea behind OSVehicle’s TABBY EVO, a modular open-source hardware platform for EVs. The platform includes pretty much everything but the body and interior of the vehicle: chassis, powertrain,… Read more »
Do you understand Tesla’s new Supercharging policy?
When Tesla introduced Model S, all EVs were new and unproven products, and many prospective buyers were worried about running out of juice. Free Supercharging for life was a sort of teaser offer that probably closed many a sale, but common sense will tell you that it couldn’t have lasted forever. Tesla replaced the “free… Read more »
All-new 2017 smart fortwo electric drive will start at $23,800

Arriving at US dealers this summer, the next-generation smart electric drive will have improved range, more power, more space and additional standard features. Daimler… Read more »
EV tech explained: Why do EVs restrict the amount of battery capacity that can be used for driving?
All EVs that use lithium-ion batteries are designed so that their full capacity can’t be used in driving – a few kWh are always left over as a buffer. Sometimes you’ll find this figure in spec sheets, which might (for example) quote capacity as “60 kWh (55 usable)” or some such. What is the reason… Read more »
Umicore invests €300 million to boost capacity in cathode materials
Materials technology specialist Umicore plans to invest €300 million ($328 million) between 2017 and 2019 to further increase its production of nickel-manganese-cobalt (NMC) cathode materials. NMC is one of the most popular cathode materials for EV batteries, and global demand is increasing fast. The increased capacity will enable Umicore to respond to a surge in… Read more »
EV fast charging in transition: What’s currently installed, coming soon and still years away?
Phoenix Contact discusses the upcoming transition phase for DC fast charging We receive a lot of press releases at Charged about plans for next-generation DC fast charging. It’s easy to lose track of exactly what is currently installed, what is coming in the near future, and what is still a few years away. Despite all… Read more »
