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 »
Williams Advanced Engineering to supply battery technology for Formula E
The fully electric racing series that is scheduled to begin in 2014. Williams will partner with Spark Racing Technology, which is building the 42 Formula E cars.
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 »
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 »
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 »
Consumer Reports: Tesla Model S is the best car since 2007 (VIDEO)
Tired of hearing about a certain California carmaker? Well, sorry. Tesla’s name is all over the press this week, from gushers about stock market success to sour-grapes hit pieces about ZEV credits to tantalizing hints of next-gen batteries and self-driving sedans. However, this is the most important news of all for a prospective Model S buyer: Consumer… Read more »
