When Protean Electric begins production of its Protean Drive in-wheel electric drive system later this year, it could mark the stirring comeback of the wheel hub motor, a concept that’s been more than a century in the making. Electric wheel-hub motors date all the way back to 1884, and none other than Ferdinand Porsche used… Read more »

A closer look at coulombic efficiency
Peter Ulrix and Stef Leemans of PEC explain how the very delicate process of measuring a cell’s coulombic efficiency could significantly speed up development times. In May, the California Center for Sustainable Energy (CCSE) put out its results for America’s biggest survey of plug-in drivers yet. More than 2,000 California EV owners responded, and while… Read more »
EVs: the Holy Grail of multiphysics
Sandeep Sovani on the evolution of computer-based engineering simulations. Before actually creating any physical prototypes, engineers build a three-dimensional virtual model of a component, and can use computer simulations to test how the design will perform in the real world. Computer-based engineering simulation early in the development process allows them to refine and validate designs… Read more »

Los Angeles to deploy BYD electric buses
The Los Angeles County Metropolitan Transportation Authority (Metro) has approved a contract with China-based BYD Motors to purchase up to 25 all-electric buses as part of a $30 million pilot project. Metro currently has a fleet of 2,238 natural gas buses operating on 183 routes. The new BYDs will be the agency’s first electric buses…. Read more »
Airbus demonstrates A320 with electric taxiing system
At the recent Paris Air Show, European jetmaker Airbus demonstrated an A320 airliner equipped with electric motors for taxiing, a technology that the company said is “showing the way for the increasingly electric future of aviation.” The Electric Green Taxiing System (EGTS) was developed by EGTS International, a joint venture of Safran and Honeywell….

Plug-In 2013 conference & exposition opens registration
Registration is now open for the Plug-In 2013 Conference & Exposition, which will focus on real data, real-world reporting and a serious analysis of what’s next for the electric highway. Returning to its roots in California – the top plug-in electric vehicle (PEV) market in the world – the sixth annual international conference, organized by the Electric… Read more »
VIDEO: Tesla demonstrates Model S battery swap
Tesla’s entire business model is built on succeeding where others have failed, so it was perhaps inevitable that it would make a go of the controversial process of battery swapping. Proponents say swapping eliminates one of the major objections to EVs: long charge times. Skeptics say it’s a complicated and cumbersome way to address an… Read more »
The $1.14 eGallon: a new tool to compare electric vs gas fueling cost
New companies and new products come and go, but it’s not so often that we get to celebrate the birth of a new unit of measurement. The DOE has invented the “eGallon” in order to provide a way to compare the cost of fueling an EV to the cost of filling up a legacy ICE… Read more »
