Could Tesla improve the Model S’s resistance to highway fires just by issuing a remote software update? This week, Model S owners were notified to update their software from version 5.6 to version 5.8. Some are reporting that, after the update, the Active Air Suspension no longer goes to the lowest setting at highway speeds…. Read more »

oneDRIVE of a kind: KLD Energy’s new propulsion system
In August 2013, KLD Energy announced that it has received official UN and IEC certification for the battery pack solution of its proprietary electric drive system. The announcement marked the end of a five-year development effort and the beginning of high-volume production for the company’s ultra-efficient turnkey oneDRIVE propulsion system. There are hundreds of different… Read more »
Web of Power: Spider9’s Operating System for Energy
Spider9 weaves a matrix for stationary energy storage and shows that when it comes to fitting battery technology into electric vehicles, it’s not all for one and one for all. Many real-world technologists and engineers take inspiration from the worlds of science fiction, where recurring themes of systems theory take shape in the Grid of… Read more »
Tesla leads in sales of California ZEV credits
To no one’s surprise, the California Air Resources Board (ARB) has announced that Tesla has sold by far the largest number of zero-emission vehicle (ZEV) credits of any automaker for the last 12 months. The California ZEV Regulation requires vehicle manufacturers to produce low-emission vehicles, including a certain number of ZEVs (battery electric or fuel… Read more »
Around the EV world in 1,000 blog posts
This is my 1,000th blog post for Charged and, since I don’t care for Champagne, I’ll celebrate the occasion by writing myself a little pat on the back and a fond recap. Since I began in October 2011, I’ve written a couple of these every day, and I’ve covered a huge variety of topics, including:… Read more »
Consortium to test multi-ratio EV transmissions in Range Rover Evoque
The Range Rover Evoque compact SUV will be the platform for a £16 million research program supported by the UK’s Technology Strategy Board. The Evoque_E program will investigate the benefits of high-speed motors and multi-speed transmissions for hybrid and electric vehicles. The project will build three development vehicles based on Land Rover’s new Range Rover… Read more »
Musk: Tesla will be producing 800 cars a week by late 2014
Tesla Motors is steadily increasing the rate of production of its Model S electric sedans, CEO Elon Musk said this week. “We’re above 400 a week at the current manpower, and not trivially above it,” Musk told Bloomberg in an interview. By late 2014, production is “going to 800 a week. I’m very confident we’ll… Read more »
BRUSA offers electric drive components in 750-volt versions for commercial vehicles
The Swiss firm BRUSA is now offering its electric-drive components, including motors, controllers, power electronics, battery packs and chargers, in 750-volt versions, which are designed for commercial vehicles and applications demanding high output. Increasing the voltage allows the current to be reduced with no loss of performance. This means that cables can be thinner and… 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 »
