Compact fast-charger combines transformer & charger
Scientists at the North Carolina State University have developed a particularly small and efficient fast charger for electric cars. Their so-called medium voltage fast charger (MVFC) combines a transformer and charger in one for charging with 50 kW and great efficiency.

Exact range indicator: A new software developed at the North Carolina State University is said to be able to calculate an EV’s range more exactly than others. It uses multiple online databases and considers factors such as road grades, traffic levels, speed limits and even the weather.
Fuel cell REx from Sweden: The Volvo Group spinout PowerCell receives 7 million Krona (963,000 USD) in funding from the Swedish energy agency, in order to develop a modular and scalable fuel cell system for commercial vehicles. It is supposed to be used as a range extender for three different vehicle sizes, ranging from 3.5 to 18 tons.
Ireland will head the Shell Eco-marathon for the first time next year. The National University Ireland, Galway, has designed the country’s most fuel-efficient car. The Geec (Galway energy-efficient car) can travel about 180 kilometres on just one euro worth of energy.
Seperator research: Scientists from the US Department of Energy’s Oak Ridge National Laborator have discovered a “promising candidate” for the separator in aqueous lithium batteries. They report that a cubic garnet material (LLZO) is highly stable as a Li-stable solid electrolyte in neutral and strongly basic solutions.

Research initiative: U.S. president Barack Obama announced the creation of a public-private research center, led by North Carolina’s State University. The ‘Next Generation Power Electronics Institute’ will focus on developing cost-competitive wide bandgap (WBG) semiconductor technologies in the next five years.

New ecodesign for electric motors: The European Commission has published the amendments to the EC 640/2009 regulation concerning the ecodesign of electric motors in their Official Journal thus making them the new standard. A transitional period of six months has been granted until the new rules outlined in Directive 2005/32/EC apply. The changes concern current exceptions for motors operating at great heights or under extreme temperatures, which will be further limited.

Low to no effect: Researchers from the universities of North Carolina and Minnesota modelled the deployment of light-duty electric vehicles (EDV) in the U.S. but could not find a consistent trend towards lower system-wide emissions of CO2. This is due to the small overall share of emissions from the LDV sector (20%) and because EDV charging still produces emissions depending on the grid mix.
