Tesla has a couple of Christmas presents for those of little faith who have been getting impatient for a couple of goodies promised for this year. A prototype battery-swapping station should be up and running within days, and details of the Roadster battery upgrade are to be released soon. “Roadster update details coming next week,”… Read more »

Renault previews new EV motor
Renault has previewed a new EV motor that it says will enter production in 2015. The synchronous electric motor offers 65 kW of power and 220 Nm (162 lb-ft) of peak torque, and features an integrated Chameleon charger. Renault designed the new motor with integration, miniaturization and simplification in mind. It uses smaller and fully… Read more »
Media skeptics pile on Tesla as stock enters the slow lane
Updated 12/19/14 12:50 pm EST to include today’s tweet from Elon Musk’s regarding battery-swap stations. Predictions are a dime a dozen (and so are alliterative clichés), but here are two that always seem to come true: any time the price of a headline stock goes down, media pundits start chiming in with “I told you so”… Read more »
Your EV may not be so green – but then again, it may.
Here we go again. A mainstream news source distills (some would say “distorts”) a complex scientific study into a sensational headline, and the online echo chamber spins the story into a narrative that’s almost the opposite of what the study actually found. The study, Life Cycle Air Quality Impacts of Conventional and Alternative Light-Duty Transportation… Read more »
How to calculate the cost of your EV conversion
More and more gearheads are converting their favorite cars (and boats) to electric drive. However, it can be tough to estimate how much a particular project will cost. The final bill may be anywhere from $6,000 for a basic city car to $125,000 for a state-of-the-art Tesla-killer. It all depends on the type of vehicle,… Read more »
Siemens and Duke Energy demonstrate smart-grid-capable EVSE
As gains in energy efficiency and the plummeting cost of home-generated solar power threaten to shrink their revenues, some electric utilities seem to see EVs as a source of future demand for centrally-generated power. A case in point is Duke Energy, which, while leading the charge against efficiency and solar in its Florida service area,… Read more »
Researchers develop dendrite-free lithium films, an important step toward lithium metal anodes
There’s a lot of interest in using lithium metal as an anode material, because of its theoretical high capacity of 3,860 mAh g−1 (around ten times that of the graphite anodes used in typical Li-ion batteries). However, it doesn’t measure up in terms of cycle life and safety requirements, and one reason is the formation of… Read more »
Washington state debates extending sales tax break for EVs
Washington Governor Jay Inslee wants to extend a sales tax break for EVs, explore giving them access to carpool lanes, and create incentives for builders to include high-speed charging in new projects. He outlined his ideas at a clean-energy conference in early November, and is expected to release specific proposals with his budget in December…. Read more »
Workplace charging takes off, boosts EV ownership
Workplace charging is exploding in popularity, and it’s encouraging more and more drivers to go electric. The DOE’s EV Everywhere Workplace Charging Challenge, a program that offers assistance to companies to provide charging to their employees, began in January 2013, and has since grown to 150 partners, which provide charging at over 300 work sites… Read more »
USABC awards funding for stop-start applications, improved electrolytes
The US Advanced Battery Consortium (USABC) has awarded $2.68 million to San Diego-based Maxwell Technologies for the development of a hybrid energy storage system for automotive stop-start applications. The competitively bid contract award is co-funded by the DOE. The 19-month program will focus on the technological and economic feasibility of adapting a 12-volt hybrid energy… Read more »
