In a recent editorial in IEEE Spectrum, author and former GM employee Ozzie Zehner asserts that electric vehicles are not as environmentally friendly as boosters claim, and may even be browner than ICEs. “Dozens of think tanks and scientific organizations have ventured conclusions about the environmental friendliness of electric vehicles. Most are supportive, but a few… Read more »

Linear Technology’s new active cell balancer
Linear’s new addition to the battery pack systems family is what it calls a “high efficiency bidirectional multicell active balancer” (part number LTC3300). Have you heard the old adage – no two snowflakes are alike? Well, the same goes for cells in a battery pack. No matter how precise the manufacturing techniques, there will always… 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 »
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 »
GM to produce next-generation EVs in South Korea
General Motors plans to produce its next generation of electric cars at its Bupyeong, South Korea, plant, as the US automaker increases its investment in the fast-growing vehicle technology. GM Korea head Sergio Rocha told journalists at this week’s Seoul Auto Show that the new model will be designed from the ground up as an… Read more »
US adding 180 public chargers per month
Both government agencies and private owners are deploying public charging stations in the US at a combined rate of about 180 units a month, according to the latest figures from the DOE. As of this writing, the US has 5,548 public charging stations, and at the current pace, will have about 7,400 by the end… Read more »
Johnson Controls to supply Li-ion batteries for Torqeedo’s electric boat motors
Torqeedo, a German-based maker of electric outboard motors and accessories, will use Johnson Controls’ Li-ion automotive battery packs to power its Deep Blue 80 hp electric boat motor. Johnson modified its PHEV battery, making it waterproof and resistant to salt water, for Torqeedo’s marine application. The battery behemoth will begin production of the new battery… Read more »
Volt battery supplier forced to return $842K in DOE funds
The bad news: a colorful scandal has emerged at another of the companies that received DOE funds to build EV-related components. The good news: this time the feds got wise to the hanky-panky in time, and are forcing the company to make amends. In 2009, Korean battery maker LG Chem received a $150-million federal grant,… Read more »
