ORNL researchers develop Virtual Integrated Battery Environment design tool
As part of the DOE’s Computer Aided Engineering for Batteries (CAEBAT) project, scientists at the Oak Ridge National Laboratory (ORNL) have developed an open-architecture battery modeling framework that integrates multi-physics and multi-scale battery models. The Virtual Integrated Battery Environment (VIBE) allows researchers to test lithium-ion batteries under different simulated scenarios. The physics phenomena of interest… Read more »
BMW i3 nearing “sustainable” rate of sales
Sales of the BMW i3 are approaching “a sustainable rate” of 12,000 i3s annually, Ludwig Willisch, CEO of BMW of North America, told Automotive News. This figure seems roughly in line with that of auto consultant Sandy Munro, who has estimated that the i3 could be profitable for the company at a global volume of… Read more »
Indiana gas station chain installs DC fast chargers (UPDATED)
Public EV chargers are popping up at all kinds of locations, including, of all places, gas stations. Convenience store chain Ricker Oil has installed nine DC fast chargers at locations in central Indiana. Ricker partnered with the Greater Indiana Clean Cities Coalition and Nissan, which offers two years of free public charging to LEAF buyers… Read more »
New hybrid Chevrolet Malibu uses tech from the Volt
The 2016 Chevrolet Malibu will be offered in a hybrid version that uses an adaptation of GM’s Voltec plug-in hybrid system. This will be the third generation of Malibu Hybrids, but the previous two had only a “mild hybrid” system that assists the gas engine. The new ‘bu is a “strong hybrid,” and can drive… Read more »
Is String Cell battery technology the future for EVs?
When it comes to finding a way to charge EVs more quickly, human ingenuity has come up with some pretty wide-ranging solutions, from battery-swapping to flow batteries that store energy in tanks of liquid electrolyte. The latest innovative idea comes from startup Tanktwo, and is called a String Battery. Tanktwo’s system replaces a vehicle’s battery pack with a container filled… Read more »
2015 Kia Soul EV: A strong contender in the growing EV market
Charged faithfully reports on every new plug-in vehicle that comes out, and while there are reasons to be excited about pretty much all of them, there’s always a question lingering in the background: Does this manufacturer plan to actively market its new EV, or is this just another compliance car, to be produced in limited… Read more »
Ionic liquid electrolytes may open the door for higher-voltage batteries
The curious case of ionic liquids: Boulder Ionics/CoorsTek Specialty Chemicals Iolyte electrolytes When you think of liquids under the brand name Coors, you think of the Silver Bullet, the Banquet Beer. You certainly don’t think of high technology, unless you’re really easily impressed by cold-activated cans. However, not everyone knows that there’s another huge conglomerate under… Read more »
Oregon explores replacing gas tax with per-mile road tax
US drivers are using less fossil fuel, a trend that’s certain to continue, as fuel-economy standards get stricter and plug-in sales grow. That’s a good thing. However, road maintenance is funded by gas taxes, and less fuel burned means less tax revenue. That’s a bad thing. “Fuel efficiency is getting better and better, which is… Read more »
Siemens saves weight and space with integrated motor and inverter
Screw it in and drive Among the companies pushing the boundaries of packaging efficiency is the German engineering colossus Siemens. The company has developed an integrated motor and inverter contained in a single housing, the Siemens Sivetec MSA 3300. The new drive unit reduces weight, frees up six to seven liters of additional space, lowers… Read more »
