Korean researchers develop ten times faster super capacitor battery

Korean researchers have developed super capacitor battery with twice as large capacity and ten times faster charge speed than conventional batteries controlling two dimensional nanomaterial structure and composition. The technology is widely expected to facilitate the development of ultra super capacitor material utilized in next generation energy industry such as electric vehicles and smart grids.

The electric double layer capacitors (EDLC) boasts high power output, faster recharge and discharge, and semi-permanent battery life. However, low energy density can restrict the application. EDLC is a type of super capacitor that stores or discharges energy within seconds by absorbing ion electrically pulled from the electrode surface.

A series of research has been conducted in advanced countries including the US to enhance the energy density by developing super capacitor electrode material. The research team found secondary nanosheet by chemically exfoliating the bulk layered compound made of transitional metal and sulfur as they would to retrieve graphene shedding off a layer of graphite before they build the two dimensional nanosheet into a three dimensional structure.

The result was published in a science magazine ‘Nano Letters’ on March 3, titled as ‘Unveiling Surface Redox Charge Storage of Interacting Two-Dimensional Heteronanosheets in Hierarchical Architectures.’

BMW doubles i8 production to meet demand

Although BMW has doubled the production capacity for the plug-in hybrid i8, the order backlog is, according to Production Director Harald Krüger still at 4.5 months.

"We are really proud to see how this demands develops for a completely new car," Kruger said at the BMW Financial News Conference. Pride partly because of the spectacular E-athletes have been accepted even better than expected in the market, and secondly because the production team at the Leipzig plant has got a handle on the production processes of the vehicle with a high carbon content faster than expected.

Since launch in summer 2014 a total of 1,741 i8 were delivered. Given the high demand BMW have doubled the production number. Currently 20 cars per day will be built. Nevertheless, demand is still rising.

Overall, BMW sold 17,793 i models last year including 16,052 i3. Norbert Reithofer acknowledged that BMW are satisfied with the development because of the valuable experience developed through the i-series with Reithofer emphasizing the goal of electrification power trains through all series.

Tesla sells record 10,030 cars in Q1, up 55% year over year

Tesla Motors delivered a record 10,030 cars in the first quarter of 2015, a 55% increase compared with the number of deliveries in the first quarter of last year.

The company said going forward it will publish the number of new car deliveries within three days of quarter end as inaccurate sources of information have sometimes been used by others in publishing the number of vehicle deliveries.

The company expects to deliver about 55,000 cars globally in 2015, an increase of about 74 percent.

Tesla Motors is also set to offer upgrades including hands-free steering on its Model S sedan in three months, about a year ahead of other automakers.

Up to Thursday's close of $191, the stock had fallen 14.1 percent this year.

Torque Vector Steering Improves Electric Vehicle Energy Efficiency

Germany's Karlsruhe Institute for Technology along with industry partner Schaeffler are researching improvements in electric vehicle energy efficiency by using brake steer or torque vector control of wheel motors to assist power steering.

The project "Intelligent Assisted Steering System with Optimum Energy Efficiency for Electric Vehicles (e²-Lenk)" subsidized by the Federal Ministry for Education and Research (BMBF) focuses on a new assisted steering concept. In conventional vehicles, the internal combustion engine not only accelerates the car but also supplies on-board assist systems with energy; such as the assisted steering system, which reduces the strain on the driver at the wheel.

In electric vehicles, this energy comes from the battery and also reduces the range as a result. In this research project by the collaborating partners, Karlsruhe Institute for Technology (KIT) and Schaeffler, the steering system is assisted in an energy-efficient manner by intelligent control of the drive torques transmitted to the individual wheels. The project is being sponsored by BMBF with a sum of around 0.6 million euros over 3 years and was started in January 2015.

"The new assisted steering system would require less system components in an electric vehicle, this would mean savings in terms of weight and energy in an electric vehicle", explain project managers Dr. Marcel Mayer, Schaeffler, and Dr. Michael Frey, KIT. "This would mean that an electric car would be cheaper and have a greater range." Materials and production steps can be saved due to the potential optimization of the design and weight.

The basic idea of the e²-Lenk project is simple: The wheels in an electric car will be driven individually by electric motors in contrast to a car with an internal combustion engine where all the wheels are provided with equal force. If the wheels on the left side transmit more drive torque to the road than those on the right side, this will result in acceleration of the vehicle to the right without the need to turn the front wheels or consume additional energy for steering.

Tracked vehicles or quadrocopters steer using the same principle. "Steering assistance can be provided while driving by means of an intelligent control system and suitable wheel suspension", says Schaeffler engineer Mayer, Manager of the Automatic Driving Working Group, which is carrying out research as part of the collaborative research project SHARE (Schaeffler Hub for Automotive Research in E-Mobility) at KIT. "Only steering when stationary remains a challenge with conventional designs."

"The assisted steering system is part of the drive train with our approach", explains Frey who is researching at KIT's Institute of Vehicle Systems Technology. Steering the front wheels is carried out without using additional energy. "We also want to significantly increase the quality of driving. Customer benefit, comfort, safety and reliability go hand in hand here."

As part of the project, functional demonstrators are being built, with which the concepts can be validated and optimized in experiments. It is also planned to implement the system in last year's Formula Student racing car KIT built by the university group KA-RaceIng with the participation of the students.

e²-Lenk is the first publicly subsidized joint project as part of the collaborative re-search project SHARE at KIT between Schaeffler Technologies AG & Co. KG and KIT. This joint project is being managed at KIT's East Campus in a joint project management office run by SHARE at KIT and the Institute of Vehicle Systems Technology (FAST).

Schaeffler and KIT are partners in the Leading Edge Cluster Electric Mobility South-West (ESW), which connects over 80 stakeholders from science and economics in the region Karlsruhe – Mannheim – Stuttgart – Ulm. The cluster strategy of the ESW cluster aims to achieve intensive regional collaboration in the field of electric mobility by means of new approaches and forms of cooperation. As a result, knowledge is developed, consolidated and ultimately advantages are achieved in international competition.

Aston Martin To Build Electric Rapide by 2018

Aston Martin Chief Executive Andy Palmer says the company may build an electric version of its Rapide sports car in two to three years as a part of its plan to overhaul its lineup and add several new models.

Mr. Palmer said the company has launched a research project for the electric car and is speaking with electric-vehicle technology companies to partner with, though he declined to say which companies.

“We are looking at technologies around the world, including some pretty cool technologies coming from Silicon Valley,” he said. Tesla Motors Inc., based in Palo Alto, Calif., isn’t one of them, he said.

Mr. Palmer, who came to Aston Martin from Nissan Motor Co., where he was an executive vice president, said the company would be producing ultraluxury special editions of its current models in the short-term to generate buzz and revenue, ahead of the new models. Aston is planning a crossover vehicle as well as an executive large sedan to compete with Rolls-Royce.

Aston Martin recently revealed an all electric DBX Concept at the 2015 Geneva Motor Show.

Chris Harris – McLaren P1 Hybrid [VIDEO]

Chris Harris takes the McLaren P1 hybrid hypercar for a drive around the UK in typical wet British weather.

The car is obviously a gorgeous piece of automotive engineering but watching this video you could be forgiven for forgetting the P1 is a hybrid. Unfortunately no mention is made of the electric powertrain until the last minute of the film when Harris hits E-mode for a short demo.

Better late than never, as the saying goes!

Automakers race to double the driving range of affordable electric cars

Global automakers are readying a new generation of mass-market electric cars with more than double the driving range of today’s Nissan Leaf, betting that technical breakthroughs by big battery suppliers such as LG Chem Ltd will jump-start demand and pull them abreast of Tesla Motors Inc.

At least four major automakers — General Motors, Ford, Nissan and Volkswagen — plan to race Tesla to be first to field affordable electric vehicles that will travel up to 320 km (200 miles) between charges.

That is more than twice as far as current lower-priced models such as the Nissan Leaf, which starts at $29,010. The new generation of electric cars is expected to be on the market within two to three years.

To get a Tesla Model S that delivers 265 miles (427 km) on a charge requires buying a version that starts at $81,000 before tax incentives. Most electric cars offered at more affordable prices can travel only about 75 to 85 miles (121 to 137 km) on a charge – less in cold weather or when drivers have the air conditioning on.

Automakers need to pump up electric vehicle demand significantly by 2018. This is when California and eight other states will begin to require the companies to meet much higher sales targets for so-called zero emission vehicles — in other words, electric cars — and federal rules on reducing fuel consumption and greenhouse gases become much stricter.

BATTERY BREAKTHROUGHS

Tesla Chief Executive Officer Elon Musk said last week that “200 miles is the minimum threshold” to alleviate consumer concerns over EV range. There is “a sweet spot around 250-350 miles that’s really ideal,” he said.

Musk has promised a more affordable Tesla, the Model 3, which will sell for around $35,000 and provide a driving range of 200 miles or more. That car is slated to begin production in mid-to-late 2017.

However, GM says it plans to field a 200-mile electric car, the Chevrolet Bolt, by late 2016.

The Bolt will use an advanced lithium-ion battery pack developed by Korea’s LG Chem, which also supplies batteries for the Chevrolet Volt hybrid. The newer batteries are said to have much higher energy density and provide much longer range between charges, thanks to breakthroughs in battery materials, design and chemistry, according to a source familiar with LG Chem’s technology.

"Several factors are at play that are landing at this 200-mile range" for a vehicle priced between $30,000 and $35,000, LG Chem Chief Executive Prabhakar Patil said in an interview. "We’ve been talking to several OEMs (automakers) regarding where our battery technology is and where it’s going."

LG Chem also supplies standard lithium-ion batteries to the Ford Focus Electric and may supply the longer-range batteries to a new compact EV that Ford is tentatively planning to introduce in late 2018 or early 2019, according to three suppliers familiar with the program.

Compared with the 2015 Focus Electric, which has a range between charges of 76 miles, the new compact electric model would have a range of at least 200 miles, the suppliers said.

Nissan and VW both have battery supply deals with LG Chem, and both are working on longer-range EVs for 2018 and beyond.

Nissan is planning to introduce a successor to the Leaf in early 2018, according to a source familiar with the program, and that model is expected to offer significantly greater range than the current Leaf, the best-selling electric car in the United States, which can go 84 miles (135 km) between charges.

The 2015 Leaf uses batteries made by a joint venture between Nissan and supplier NEC. It is not clear if the future model will shift to LG Chem, although Nissan CEO Carlos Ghosn has identified LG Chem as a potential battery supplier.

VW plans to expand its current range of electrified vehicles, including a successor to the battery-powered e-Golf in 2018 with much longer range, according to two sources familiar with the program. The current e-Golf uses batteries made by Panasonic and has a range between charges of 83 miles.

Volkswagen plans to decide in the first half of this year whether new battery technology under development at U.S. startup QuantumScape Corp, which may expand an electric vehicle’s driving distance between recharges to as much as 700 kilometers (430 miles), is ready for use in its electric cars.
