Battery breakthrough set to accelerate electric-car development

A team of scientists working at the Massachusetts Institute of Technology are claiming a significant breakthrough in recharging times for lithium-ion batteries. According to findings published in the scientific journal Nature, MIT researchers Byoungwoo Kang and Gerbrand Ceder have unlocked the potential of lithium-ion batteries by patenting a unique process which is claimed to allow a typical laptop power pack to be fully recharged in less than a minute--an improvement in recharging performance of roughly 90 percent over existing lithium-ion batteries. Lithium-ion batteries generate electric current via the flow of lithium ions across an electrolyte, from an electrode to a cathode.

Brake issue prompts recall of BMW and Rolls-Royce vehicles

BMW is recalling about 198,000 cars with V8 and V12 engines to fix a problem with the brake system. The automaker said a potential leak in the brake system could cause a loss of vacuum, which would reduce the power braking assistance. BMW said the mechanical brakes will stop the vehicle even if there is a vacuum leak.

Nissan reveals Leaf Autonomous Drive prototype

What a difference a year makes. Last year Nissan exhibited a self-parking car at CEATEC, Japan's largest show for IT and electronics. Back then a Nissan NSC-2015 concept car, a Nissan Leaf with what seemed like a couple hundred pounds worth of computers in the trunk, was able to find a parking spot for itself under controlled conditions and park itself.
