VW Chairman thinks solid-state batteries can deliver 700 km range

Following persistent news leaks from 'highly placed insiders' about an all-electric version of Audi's upcoming Q8 sports SUV with 700 km battery range, VW Chairman Prof. Dr. Martin Winterkorn, has hinted at the battery technology Audi may use to achieve that range.

In a speech at Stanford University, during the award of the 3rd Science Award for Electrochemistry, Dr Winterkorn said he sees great potential in solid-state batteries.

"Increasing the specific energy of lithium-ion cells to as much as 380 Wh/l will reduce driving range drawbacks.

With a higher nickel content, much more will be feasible.

But we also need to intensify basic research into batteries with an even greater specific energy, such as solid-state batteries.

I see great potential in this new technology, possibly boosting the range to as much as 700 kilometers (1,000 Wh/l)."

In March we reported that VW were bench testing new battery chemistry capable of providing "between three and four times the power" from a given capacity. This would mean up to 80kWh from a similar volume occupied by the current Golf Blue-e-motion's 26.5kWh battery pack.

Dr Heinz-Jakob Neusser, VW board member responsible for development, speaking at the Geneva motor show, refused to name the battery chemistry, but doesn’t deny it is a lithium-air unit, which are capable of delivering huge amounts of power, but are in the very early stages of development.

Given Dr Winterkorn's statement that current energy density with lithium-ion batteries, which allow a range of 190 kilometers, is 260 Wh/l and in the same speech he references solid-state batteries @ 1,000 wh/l, a 4x increase, I think it becomes clear this is the chemistry VW are bench testing.

The Science Award Electrochemistry was initiated by BASF and Volkswagen in 2012. The aim being to foster exceptional scientific and engineering achievements in electrochemistry and to provide an incentive for the development of high-performance energy storage.

LG Chem officially breaks ground for China EV battery plant

LG Chem held a ground breaking ceremony for the construction of electric-car battery plant in Nanjing, China, to meet growing demand in the world’s biggest car market.

The Nanjing battery plant, with an annual production capacity of more than 100,000 electric vehicles when completed by the end of 2015, will supply batteries to Chinese automakers like SAIC Motor Corp, Qoros and many other global carmakers in China. It was 'only' 7 months ago LG Chem's CEO said they were "considering" this EV plant in China!!

Among the key participants who joined the groundbreaking ceremony were Miao Rui Lin, the Mayor of Nanjing; Luo Qun, the vice mayor; and YS Kwon, the President of Energy Solution Company of LG Chem.

LG Chem set up a joint venture in August with two Chinese state-run companies - Nanjing Zijin Technology Incubation Special Park Construction Development Co, Ltd. and Nanjing New Industrial Investment Group Ltd. - to start manufacturing EV batteries in China. LG Chem owns half of the joint venture while the other half is shared by Chinese partners.

The Korean battery giant said it has been investing hundreds of millions of dollars into the factory and expects a total of 1 trillion won (AUD$1 Billion) in revenue by 2020, just by the batteries produced in Nanjing.

BMW likely to phase out internal combustion engines over the next 10 years [VIDEO]

During a recent interview with CNBC.com , mutual fund manager Ron Baron of Baron Capital revealed that two of his analysts recently visited BMW in Germany and the BMW financial team believes that a "revolution in the drive train is underway."

"We believe that BMW will likely phase out internal combustion engines over the next 10 years,"
Baron wrote in his most recent quarterly letter to shareholders of his funds.

Almost exactly 12 months ago, BMW product chief Herbert Diess told Autocar "all BMW models will soon need to be sold with some form of electrification." BMW’s head of production for large vehicles, Peter Wolf, told motoring.com.au. “We are planning to have a plug-in hybrid in each and every model series.”

We have also regularly reported on a steady stream on informal announcements from German automakers (Audi, BMW, Mercedes, Porsche) regarding their plans to build a 'Tesla killer', but Wall Street financial analysts concluding a major automaker may abandon the production of ICE power plants within a decade still comes as a revelation. It was only four years ago (December 2010) the first mass market electric vehicle, the Nissan Leaf, began deliveries to retail customers.

Baron, who holds a $250 Million position in Tesla Motors, believes that of all the major automakers, BMW is the only car company with a 'culture' comparable to that of Tesla. Baron believes the rest of the auto industry is resisting the move to electric vehicles. "As a result, they are developing electric expertise so slowly that the lead Tesla has built up through its fast growing staff ... may soon become insurmountable."

He argues automakers don't want electric vehicles to happen because their engine and transmission plants would become stranded assets. Unions don't want EVs to happen because they are easier to assemble which results in fewer jobs and dealers don't want EVs to happen because of direct sales and lack of vehicle servicing. Electric cars have 18 moving parts compared to 2,000 moving parts in a combustion engined car. EVs simply don't wear out or breakdown leading to lost automaker/dealer revenues.

With global auto sales heading towards 100 Million a year, Baron believes that in 15 years time Tesla could be selling 10 Million vehicles a year.

Supercapacitor panel-powered EVs a ‘reality’ in 5 years say QUT researchers

A car partly powered by its own body panels could be on our roads within five years following the development of breakthrough nanotechnology by Queensland’s University of Technology.

Researchers at QUT have succeeded in developing lightweight ‘supercapacitors’ that they say can be combined with regular batteries to dramatically boost the power of an electric car.

The supercapacitors – described as a ‘sandwich’ of electrolyte between two all-carbon electrodes - were made by the research team into a thin and extremely strong film with a high power density.

The development means that the film could one day be embedded in a car’s body panels, roof, doors, bonnet and floor - storing enough energy to turbocharge an electric car’s battery in just a few minutes.

The findings, published in the Journal of Power Sources and the Nanotechnology journal, are the result of the work of the team comprising Postdoctoral Research Fellow Dr Jinzhang Liu, Professor Nunzio Motta and PhD researcher Marco Notarianni from QUT’s Science and Engineering faculty – Institute for Future Environments, and PhD researcher Francesca Mirri and Professor Matteo Pasquali, from Rice University in Houston in the United States.

According to Marco Notarianni, the car partly powered by its own body panels could be a reality in the next five years.

“Vehicles need an extra energy spurt for acceleration, and this is where supercapacitors come in. They hold a limited amount of charge, but they are able to deliver it very quickly, making them the perfect complement to mass-storage batteries.

“Supercapacitors offer a high power output in a short time, meaning a faster acceleration rate of the car and a charging time of just a few minutes, compared to several hours for a standard electric car battery.”

Dr Liu says one of these cars, after one full charge, should be able to run up to 500km – “similar to a petrol-powered car and more than double the current limit of an electric car."

According to Dr Liu, currently the ‘energy density’ of a supercapacitor is lower than a standard lithium ion (Li-Ion) battery, but its ‘high power density’, or ability to release power in a short time, is far beyond a conventional battery.

“Supercapacitors are presently combined with standard Li-Ion batteries to power electric cars, with a substantial weight reduction and increase in performance.

“In the future, it is hoped the supercapacitor will be developed to store more energy than a Li-Ion battery while retaining the ability to release its energy up to 10 times faster – meaning the car could be entirely powered by the supercapacitors in its body panels.”

Dr Liu says the technology would also potentially be used for rapid charges of other battery-powered devices.

“For example, by putting the film on the back of a smart phone to charge it extremely quickly.”

Another member of the research team, Professor Nunzio Motta, says the technology discovery may be a game-changer for the automotive industry, with significant impacts on financial, as well as environmental factors.

“We are using cheap carbon materials to make supercapacitors and the price of industry scale production will be low.

“The price of Li-Ion batteries cannot decrease a lot because the price of Lithium remains high. This technique does not rely on metals and other toxic materials either, so it is environmentally friendly if it needs to be disposed of.”

The QUT researchers who made this discovery are part of the university’s Battery Interest Group, a cross-faculty group that aims to engage industry with battery-related research.

Model S Achieves Euro NCAP 5-Star Safety Rating [VIDEO]

The Tesla Model S has received a maximum-possible 5-star safety rating from the European New Car Assessment Programme (Euro NCAP).

Model S is one of just a few cars to have ever achieved a 5-star safety rating from both Euro NCAP and the U.S. National Highway Traffic Safety Administration (NHTSA). Additionally, Model S is the only car this year to have achieved both a 5-star Euro NCAP rating and 5 stars in every NHTSA subcategory, including frontal impact, side impact, and rollover. Only two other cars have earned the same recognition since 2011 (when NHTSA introduced its latest rating scheme).

The reason so few models achieve 5-star ratings in both Europe and the U.S. is that each program places emphasis on different safety aspects in the assessment process. NHTSA emphasizes structural and restraint safety, with a deep focus on how well the vehicle can withstand and absorb the energy of an impact while protecting its occupants. It is also primarily concerned with adult occupants. On the other hand, Euro NCAP assesses a wider range of scenarios, including tests for child and pedestrian safety. Unlike for NHTSA, active safety is also an important part of Euro NCAP’s 5-star requirement. Every year, the European organization raises the standard for a 5-star rating to account for technological advances in the industry.

The dual 5-star ratings for Model S validate our holistic approach to safety. We have been engineering passive and active safety systems in parallel, so the car is structurally sound and is also designed to intelligently anticipate and react to potentially dangerous situations.

Structurally, Model S has advantages not seen in conventional cars. It has a low center of gravity because its battery pack, the largest mass in the car, is positioned underneath the passenger compartment, making rollover extremely unlikely. It also has a large front crumple zone because of the lack of an engine, meaning it can absorb more energy from a frontal impact, the most common type of crash resulting in fatalities. Its body is reinforced with aluminum extrusions at strategic locations around the car, and the roof can withstand at least 4 g’s. It was for these reasons that Model S achieved 5 stars in every subcategory when tested by NHTSA in 2013.

This quarter, we started implementing the Model S active safety system in conjunction with the introduction of new Autopilot hardware, consisting of 12 ultrasonic sensors that sense up to 16 feet around the car, a forward-looking camera, a forward radar, and a digitally controlled, high-precision electric brake boost. We specifically selected this hardware to accommodate the progressive introduction of new safety features via software updates over the course of the next several months.

While the features already pushed to the Model S fleet – Lane Departure Warning and Speed Limit Warning – have proven sufficient to merit a 5-star NCAP rating, we will go much further with active safety systems. Features coming soon include Forward and Side Collision Warning and Avoidance, Blind Spot Warning, and Automatic Emergency Braking.

The video shows the Frontal Impact test which takes place at 64 Km/h, 40% of the width of the car striking a deformable barrier. In the side impact, a mobile deformable barrier impacts the driver's door at 50 km/h. In the pole test, the car tested is propelled sideways at 29km/h into a rigid pole.

Electric RaceAbout annual Nordschleife testing [VIDEO]

Electric RaceAbout ran the annual tests on the legendary Nordschleife track in Nürburg Germany in the end of October. E-RA went around the 20,6 km long, so called Sport Auto lap, in 8:01,41 beating its own best time.

Last years visit in Nordschleife gave a lot of inspiration and ideas to E-RA team, how to continue improving the performance and reducing the weaknesses of the car. During the past year, the whole vehicle has been developed, but the most remarkable things were the active rear wing control, suspension and ABS brake system. The Torque Vectoring control system of the motors has also been improved since last year.

This time E-RA was driven by Jesse Krohn, a young Finnish VLN- series professional driver and his comments concerning the performance and strengths of E-RA are similar with our teams earlier test drivers. “The drive ability of the vehicle was good regarding its weight and the acceleration from 100 to 200 km/h was very convincing”, says Jesse, who drove the vehicle for the first time.

The testing period in the end of October lead to the second fastest lap around the Nordschleife track in the street legal electric vehicle group. The unpredictable Eifel mountain range climate did not help the testing and E-RA was on the track only three times in four days.

“The low amount of laps did not help me get accustomed to the vehicle”, says Jesse and continues: “Also, we had to start every lap with cold tires and brakes”.

During the fastest lap, the battery of the vehicle heated up more than the team anticipated and the battery output power had to be limited from halfway of the track to the end. Additional laps would have helped to optimize the vehicle setup - there is still potential for a faster lap-time.

The best time of the EV's on Nordschleife still remains with Mercedes-Benz AMG SLS Electric Drive 7:56,2.
