Juicy details about the BMW i3
BMW has released a vast wealth of details about its upcoming i3 EV, and there’s plenty here for auto pundits to discuss before the official unveiling, which is scheduled for July 29. The i3 embodies several milestones – it’s the first EV to offer an optional range extender engine, it features a unique carbon-fiber-reinforced plastic… Read more »
A reluctant gem: The FIAT 500e EV
The cute, cuddly FIAT 500e EV may have been born only out of regulatory necessity. So what happens if it becomes the best-reviewed new EV in its class? The bar is raised; the game changes. Maybe Chrysler will even concede that it should sell it outside of the Golden State. Summertime in Sonoma County… 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 »
A new LEAF, localized manufacturing, and a focus on infrastructure
With a longer range and a lower price, the 2013 Nissan LEAF screams upgrade, but it’s only one small aspect of the company’s aggressive EV strategy. Proprietary, localized manufacturing and improved infrastructure also play key roles in Nissan’s plan for world domination electrification. Sometime back in the 60s, Mr or Mrs Ghosn must have put… Read more »
Working together: avoiding EVSE-to-vehicle interoperability issues
Intertek’s Rich Byczek on avoiding EVSE-to-vehicle interoperability issues. Back in January, Plugincars.com published an article by Colby Trudeau – a Honda Fit EV owner, Plug In America volunteer, and electrical engineer at Qualcomm Technologies – that detailed his charging troubles using Ecotality’s Blink charging stations at work. Trudeau found that after about 20 minutes… Read more »
Two new in-wheel electric drive systems unveiled
In-wheel electric drive systems are a hot topic these days. Mounting the electric motor and power electronics within a wheel assembly can improve efficiency, save space and give automakers more flexibility in body design. This week, two leaders in the field introduced new in-wheel offerings. Protean Electric announced the debut of its production in-wheel motor… Read more »
New Porsche Panamera PHEV
Porsche is introducing its first plug-in hybrid – the Panamera S E-Hybrid. It’s part of a new generation of Panamera models that will debut at Auto China in Shanghai later this month, and will go on sale late in 2013. The S E-Hybrid improves upon the previous Panamera S Hybrid with a more powerful electric… Read more »
McLaren P1 delivers instant torque with twin power plants
The McLaren P1 looks like it belongs on a race track, but its maker hints that this “production-ready version” might someday be an option for your daily commute. The super-PHEV, which will make its world debut at next week’s Geneva Motor Show, uses the combined force of a V8 gas engine and an electric motor… Read more »
