Bosch and PSA Peugeot Citroën presented two prototype vehicles that use the Optimal Energy Consumption and Recovery (OpEneR) system at the International Environmentally Responsible Car Show (RIVE) in Alès, France. OpEneR is a European research project designed to increase the range of future hybrid and electric vehicles by optimizing energy management. Launched in 2011, OpEneR… 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 »
OCPP: There’s definitely confusion, but is there controversy?
Reporting on the charging industry is a tough gig. It’s incredibly nuanced. Every question we ask the experts leads to three more questions. It turns out that when you take hardware, software, networks, protocols and panels, then mix in some public funding, you get endless opinions. We’ll attempt to clarify two issues in the thick… Read more »
Unclean at Any Speed: constructive criticism or anti-EV hit job?
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 »
Navigant Research releases Leaderboard Report on lithium-ion battery manufacturers
In a new report, Navigant Research profiles 11 Li-ion battery vendors that are active in the EV market, and rates them on 13 criteria, including systems integration, safety engineering, chemistry performance, geographic reach, manufacturing and product performance, pricing, and overall corporate financial health. According to Navigant, “Li-ion batteries have won the race to be the chemistry… 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 »
