Rising above the waters of the Mittelland Canal in Wolfsburg, Germany, four iconic smokestacks cut through an otherwise sparse skyline. These are the most recognizable – and among the last – vestiges of the original Volkswagen factory from 1938. Symbolically, however, the smokestacks represent much more than the symbols of a power plant that –… Read more »

AutoLion Li-ion battery simulation software claims a unique modeling technology
Super modeling: EC Power’s AutoLion claims unique technology, reliable results and extraordinary savings in development time and cost With battery technology being one of the key bottlenecks slowing down the widespread adoption of electric vehicles, Pennsylvania’s growing startup EC Power proposes a tantalizing offer to battery developers: cut your product development cycle by around 20 percent, and… Read more »
Tesla’s batteries – past, present and future
This article is an excerpt from Tesla Motors: How Elon Musk and Company Made Electric Cars Cool, and Sparked the Next Tech Revolution by Charged Senior Editor Charles Morris. Tesla seems to make a point of doing things differently than other automakers, and its battery pack – the most critical component of any EV –… Read more »
Researchers move another step closer to Li-air batteries
A team from Delft University in the Netherlands and the University of Waterloo in Canada has used operando X-ray diffraction to show that oxidation of electrochemically generated lithium peroxide (Li2O2) in high-energy-density Li-air batteries occurs in two stages, but in only one step for commercial (crystalline) Li2O2. In a paper published in the Journal of… Read more »
Toyota researchers work with Brookhaven National Lab to investigate magnesium batteries
Toyota researchers are collaborating with the Center for Functional Nanomaterials (CFN) at the DOE’s Brookhaven National Laboratory to probe molecular structures and track chemical reactions in magnesium batteries. “Issues related to cost, power, energy density, and durability of Li-ion batteries have slowed their implementation in large-scale applications, such as electric and hybrid vehicles,” said Toyota… Read more »
Analyzing heat-driven decay in nickel-cobalt-aluminum batteries
A set of three recent studies funded by the Korean government investigated a family of lithium-ion batteries composed of nickel, cobalt and aluminum. NCA batteries offer high energy density, but degrade significantly with each charge/discharge cycle. The high heat of vehicle environments can intensify the degradation, and even cause complete battery failure. Researchers at the… Read more »
Simulation of battery pack cooling systems: measure twice, cut once
The experts at Mentor Graphics walk us through the simulation and analysis of a battery pack cooling system. In the business of battery pack design, one of the main considerations is cooling. The pack must have a uniform and stable temperature for the batteries to perform adequately during worst-case conditions. Even within a single cell,… Read more »
New software uses big data to calculate a more accurate estimate of remaining range
Researchers from North Carolina State University have developed new software that promises a better way to estimate the remaining range of an EV. The system requires drivers to plug in their destination and automatically pulls in data on several variables to predict energy use. The team described their work in a paper, Big-Data Framework for… Read more »
Scientists increase manufacturing speed of electrode foils by 3x, promising lower costs
Researchers around the world are working on improving various aspects of battery performance – capacity, charging speed, usable life. Scientists at the Karlsruhe Institute of Technology (KIT) are focusing on the speed with which they can be manufactured, which has a direct effect on costs. The researchers have increased the manufacturing speed of electrode foils… Read more »
GM releases details of next-generation Volt powertrain
GM has released some details of the second-generation Voltec electric-drive system that will power the 2016 Volt. According to Volt Lead Engineer Andrew Farah, the primary goals for the new powertrain were to improve performance, raise overall efficiency, and cut engine noise. The new Volt has a pair of electric motors, either or both of… Read more »
