Battery Electric Vehicles

A team of Ford hybrid engineers, a fuel efficiency expert and a NASCAR star have driven a 2010 Ford Fusion Hybrid 1445.7 miles (2313.12 km) on a single 17.5 US gallon (66.24 Liter) tank of gasoline using Eco-Driving techniques. That's an average of 81.5 mpg (2.88 l/100 km), not bad from a totally standard production car. The 1,000-Mile Challenge started at 8:15 a.m. on Saturday, April 25, from Mount Vernon, Va., and the car finally ran out of gas and battery power on April 28th at 5:37 am in Washington, D.C. NASCAR star Carl Edwards was behind the wheel at the 1000 mile mark and world-record breaking hypermiler Wayne Gerdes was also part of the team. Read More

Chrysler this week announced it will use batteries from A123 Systems in its range of Electric Vehicles, the first of which should be a Tesla Roadster competitor - the Dodge Circuit. A123 and Chrysler have been working together over the last three years to develop a modular battery system based on prismatic cells using the same lithium iron nano-phosphate chemistry that has already gained a huge reputation following the world records set by Killacycle.

The 1925 Sunbeam Tiger was a supercharged V12 four-liter racing car, driven by Sir Henry Segrave at 145 mph (233 km/h) and was the smallest-engined car ever to hold the world land speed record. The Sunbeam Tiger electric sports car concept has been designed to "virtually" commemorate the 100th anniversary (1925-2025) of the Tiger's land speed record win. The Tiger concept car is powered by a Siemens 3 phase AC motor powering the rear wheels with a 26 kilowatt/hour lithium-titanate battery pack and has a curb weight of 600kg (1323lb). Read More

Cars like the million dollar Porsche Carrera GT and Ferrari Enzo are rightly considered supercars with their lightweight carbon fiber construction and 650 hp (477 kw) thoroughbred mid mounted engines making them capable of 0-60 mph in 3.9 seconds. The amazing thing is that electric vehicles like the 250 hp (183 kw) Tesla Roadster, which produce 100% instant torque from zero rpm, can accelerate to 60 mph in the exact same time, and at costs as low as $0.02 per mile. Paul Evans takes a look at the leading lights of this new breed of speed demon - the top 5 fastest Electric Vehicles in the world. Read More

Straight out of left field, General Motors and personal mobility pioneer Segway have revealed a two-wheel, two-seater prototype vehicle they’ve code named Project P.U.M.A (Personal Urban Mobility and Accessibility). The self-balancing electric “car” is designed to transport two adults in a seated position at speeds of up to 35 mph and can travel up to 25 and 35 miles (40 - 56 km) powered by large format lithium-ion batteries on as little as $0.60 worth of electricity. The control system is based on the original Segway with dynamic balancing and drive-by-wire for acceleration, steering, and braking. It also features vehicle-to-vehicle communications, digital smart energy management and a dockable user interface that allows off-board connectivity. Read More

There is much excitement and publicity surrounding the launch of the long awaited all electric sedan from Tesla Motors and more details have emerged since the Tesla Model S was unveiled. The specs that have officially been announced are not yet substantial enough for a full technical review at this stage, but we do know that the EV sedan has a top speed of 130 mph, is capable of 0-60 in 5.6 seconds, charges in 45 minutes and has a 160 mile (256 km) range with the standard battery option. According to the company's website we can expect to see an AWD option somewhere in the future and although it's not not officially stated, according to reporters at the the unveiling who were able to question Tesla engineers the Model S will be rear wheel drive (RWD) in its standard configuration. Gizmag's Paul Evans takes a closer look at what we know, and what questions remain unanswered. Read More

A Solar car called Power Of One (Xof1) claimed a new unofficial world distance record for a solar powered car when it arrived in Los Angeles on March 6th having driven over 12,5000 miles (20,000 km) using only sunshine as fuel. Read More

Tesla has just pulled the wraps off its eagerly awaited EV sedan - the Model S - and on first impressions, it doesn't disappoint. Gizmag's Dave Weinstein has brought us these first pics from the coal-face. Read More

It has been a big week for news on advances in energy storage technology. We recently reported on new research that makes a Lithium Ion battery perform more like a supercapacitor, now we can report on research on a supercapacitor that performs more like a battery. Researchers at the University of Maryland and the Korea Advanced Institute of Science and Technology have developed a supercapacitor with 10 billion nanoscale capacitors per square centimeter, giving it 250 times greater surface area than that of a conventional capacitor of comparable size. The Nano Supercapacitor is being developed primarily as part of a hybrid battery-capacitor system for electric cars. Read More
