Islands make perfect EV habitats. Driving distances are generally short, and the need to ship supplies from the mainland keeps gas prices high. Also, islands around the world face a lot of environmental challenges, and many island economies depend on tourism, so the level of green consciousness tends to be high. Island governments around the… Read more »

In-wheel house: Protean Electric’s in-wheel drive system nears production
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 »
Bosch, Yuasa and Mitsubishi to work together on next-generation batteries
The race to develop the next generation of batteries is in full swing. This week, three major automotive players decided to pool their efforts. Robert Bosch, GS Yuasa and Mitsubishi have agreed to set up a joint venture to work together on lithium-ion battery R&D. The headquarters of the new organization will be in Stuttgart,… Read more »
Johnson Controls to supply batteries for 120 hybrid work trucks in DOE program
About 120 work trucks, to be used by various utilities and electric companies, will use plug-in hybrid power systems by Odyne Systems, using Johnson Controls’ batteries.
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 »
OXIS Energy bets on lithium-sulfur
Though it may have a stinky reputation, sulfur could set EVs on the path to total ICE replacement if energy-dense, low-weight lithium-sulfur batteries become the norm. British-based OXIS Energy is banking its business on it. If American clean energy industries are to take full advantage of the emerging lithium-sulfur (Li-S) battery chemistry, they just may… Read more »
Ultracapacitors creep into automotive
Maxwell looks to leverage its early ultracapacitor experience into a ubiquitous, low-cost, high-volume complement to batteries. Power sources like internal combustion engines and advanced battery packs work great as continuous suppliers of energy. But during the highest peak loads, both sacrifice efficiency attempting to meet the power delivery demands. And pushing these devices to their… Read more »
Erik Spek on battery abuse testing, improving safety, and developing standards
(This article originally appeared in Charged Issue 7 – MAR/APR 2013) Q&A with Erik Spek: The Chief Engineer at TÜV SÜD Canada on battery abuse testing, improving safety, and developing standards. When analyzing the current state of lithium-ion technology, it helps to look back at the development of the nickel metal hydride battery (NiMH). Some argued that hybrid automotive… Read more »
It’s in the details: Digatron Firing Circuits’ new stop-start testing rig
Digatron Firing Circuits’ new stop-start testing rig examines the limitations of lead-acid batteries and the inadequacy of traditional static tests. As the battery in a stop-start system ages, the fuel efficiency advantages are curtailed. It’s a real problem found in some first-generation systems, and has led many to question the methodology used in urban-efficiency tests…. Read more »
Oak Ridge researchers give solid Li-ion electrolytes a new spin
Their novel approach offers an advantage in terms of safety and also results in a broad (5 V wide) electrochemical window.
