News: General Motors stands by electric cars in the face of dismal sales

 

57,000 sales out of just over 14-million. That's how many electric cars sold in the United States last year, causing more than a few people to announce the second death of the electric car. But General Motors' US president Mark Reuss has come out fighting for the battery car, saying that he expects Americans to embrace the technology more and more. 

“The electric vehicle is not dead. We at GM believe that the public will accept and embrace electric vehicles. Some people already have" said Reuss at the Automotive News World Congress in Detroit. 

 He also promised that not only would the next generation of Chevrolet Volt, sold here as the Opel Ampera, have a greater battery range, it would also be thousands of dollars cheaper, as GM is now able to make batteries and electric drivetrains more efficiently. 

News: Electric vehicles to get noisy

Electric vehicles are set to lose one of their most distinctive features this year, as a new US law compels them to make noise at low speeds.

In spite of the slience that mass electric motoring could potentially bring to our cities and towns, US lawmakers have decided that all electric and hybrid cars must emit an automatic warning sound at low speeds so that blind or partially sighted pedestrians don't walk out in front of them.

The move is set to prevent 2,800 injuries and as many as 35 deaths per year.

Currently, the Toyota Prius is designed to automatically emit a low whirring noise at low speeds (below 25kmh) and the Nissan Leaf has a similar system that works at the drivers' discretion. From this year though, all similar cars will have to have a system that works automatically, without driver intervention or choice. The proposed law is being introduced by the National Highway Traffic Safety Administration.

"Our proposal would allow manufacturers the flexibility to design different sounds for different makes and models while still providing an opportunity for pedestrians, bicyclists and the visually impaired to detect and recognize a vehicle", said NHTSA Administrator David Strickland.

News: Could cheaper electric car batteries be coming soon?

New research being carried out by the University of California and Bosch could lead to smaller, faster-charging batteries for electric cars within three years.

Professor Miroslav Krstic and postdoctoral fellow Scott Moura of the University of California, San Diego have been researching into the way Lithium atoms 'behave' (if that's quite the right word) in a battery. Astonishingly, it seems that we don't actually have any great knowledge of exactly how chemical components of modern batteries behave, and this new research is helping to break down that barrier.

The upshot is that we could shortly have batteries with much greater capacity, meaning that they could either make a car go for longer distances, or the same distance with a smaller battery. Even better, these new battery designs could cut lengthy charging times by as much as half, and be on sale within half a decade or so. They could even become significantly cheaper to manufacture as a result.

"If one could have a better knowledge or better estimation of what's going on inside, one could safely operate closer to the limits of performance, which means that the oversizing and overdesign would be less necessary”, Krstic told Automotive News. "That translates into savings in costs and in weight."

 

News: Toyota breaks more electric records

Toyota has been out breaking electric car records again, with its TMG EV P002 electric race car setting a new electric record on the legendary 20.8km Nürburgring Nordschleife circuit in Germany.



Using TMG’s (Toyota Motorsport GmbH) motorsport-tuned electric powertrain, driver Jochen Krumbach set a lap time of 7mins 22.329secs, breaking the electric record set by TMG last August by over 25 seconds.

This achievement marks the second milestone for TMG’s electric powertrain this year following its new record at Pikes Peak International Hill Climb in Colorado, United States.

As with the Pikes Peak success, TMG’s latest electric milestone used pioneering off-board battery-to-battery charging technology.

The TMG DC Quick Charger was developed in partnership with Schneider Electric GmbH to meet the challenge of recharging an electric race car at tracks without reliable access to grid power.

Mounted in the rear of a Toyota Hiace van, the TMG DC Quick Charger uses Schneider Electric’s EV Link technology and includes a 42kWh lithium ion battery, which can be charged direct from the AC power grid.

After an overnight charge, the TMG DC Quick Charger is able to quickly deliver high levels of power to a battery-based electric car without additional installation or infrastructure, making it the perfect solution for electric motorsport.

Ludwig Zeller, TMG General Manager Electrics and Electronics said that “Since our Nürburgring record last year, we have developed our electric powertrain to deliver more power, more consistently, over a longer distance by managing the temperature of batteries, motors and inverter. Pikes Peak was a clear illustration of the improvements and we have now reinforced that at the Nürburgring.

"But this achievement is not only about on-track performance; we are also very proud of the DC Quick Charger which again provided a reliable power supply in a remote location. This is an aspect of electric motorsport which has not been discussed at length but it is very significant; electric race cars need to be charged and it is a challenge to have the right infrastructure at race tracks, particularly temporary street circuits. Together with our partners at Schneider Electric, we have developed a solution to charge a race car literally anywhere in the world. This, along with the TMG EV P002 powertrain, represents a major step forward for electric motorsport.”
