Charged with Electric Vehicle News and Views
The smart fortwo electric drive is a champion of urban mobility. But is it a champion of the drag strip? Against some of the fastest cars in the city?!
Remember, in urban driving top speed means nothing, it's the first 5 meters that count!
Wide bandgap (WBG) materials such as silicon carbide (SiC) and gallium nitride (GaN) are best positioned to address emerging power electronics performance needs in electric vehicles (EVs), with SiC displacing silicon as early as 2020, according to Lux Research.
As silicon struggles to meet higher performance standards, WBG materials are benefiting critically from evolving battery economics. On Tesla Model S, for example, a 20% power savings can result in gains of over $6,000 in battery cost, or 8% of the vehicle's cost.
"Efficient power electronics is key to a smaller battery size, which in turn has a positive cascading impact on wiring, thermal management, packaging, and weight of electric vehicles," said Pallavi Madakasira, Lux Research Analyst and the lead author of the report titled, "Silicon vs. WBG: Demystifying Prospects of GaN and SiC in the Electrified Vehicle Market."
"In addition to power electronic modules, opportunities from a growing number of consumer applications -- such as infotainment and screens -- will double the number of power electronic components built into a vehicle," she added.
Lux Research analysts evaluated system-level benefits WBG materials are bringing to the automotive industry, and predicted a timeline for commercial roll-outs of WBG-based power electronics. Among their findings:

According to a recent report, Tesla could launch up to four new models by 2018.
While we already know about the Model X and the Model 3, Autobild is reporting the company is considering a compact city car.
Little is known about the vehicle - which has been dubbed the Model C - but it would be smaller and more affordable than the Model 3 which is expected to cost approximately $35,000.
The magazine goes says a new roadster - dubbed Model R - could arrive in 2017. This seems to contradict statements from Tesla CEO Elon Musk who has previously said an all-new Roadster is at least five years off. However, the wait could be worth it as Tesla's vice president of sales, George Blankenship, has previously suggested it could accelerate from 0-60 mph in less than four seconds and have a range in excess of 200 miles (322 km).

Nissan Motor and Mitsubishi Motors will work together to develop a minicar-based electric vehicle, aiming to release a new model in fiscal 2016 at the lowest price among major automakers.
The carmakers have set up a 50-50 joint venture to pursue development.
Nissan, which released the Leaf electric car in 2010, is the world's largest manufacturer of electric vehicles, with global sales of at least 124,000 units. Mitsubishi has a track record in this area as well, including the minicar-based i-MiEV released in 2009. They plan to co-produce the new car and work together to procure such key components as lithium-ion batteries.
The i-MiEV is the cheapest electric passenger car on the Japanese market, starting at $26,440. When government subsidies of up to $7,760 are included, it can be purchased for as little as $18,680.
By basing the new EV on a minicar, Nissan and Mitsubishi expect to sell it for around $15,000 including subsidies, the lowest price among major automakers and similar to gas-fueled compacts.
Auto Bild has revealed Audi plans to catch-up with the competition in automotive electrification with two purely electric Audi SUV, the A2Q and Q6 expected around 2017/18.
A2Q with up to 500 km electric range
If the expected advances in battery technology are true, the compact A2Q, expected in 2016, will have 500 km battery range. Seen as a competitor against BMW's i3, Audi will not develop a completely new electric platform but uses the familiar MQB modular architecture of Golf/A3.
Audi Q6 as Tesla competitor
The Q6, internally designated within Audi as the Tesla Fighter, is expected to be a coupe-like offshoot of the Q5 and come with 700 km battery range with a launch date around 2017. A larger battery powered Q7/8 is also expected around 2017.
There are only a few minutes before your flight check-in closes, or before your train departs, but you now have to spend precious time hunting for a free space at the airport or station car park. Imagine leaving your vehicle at the main entrance and letting the car do the rest on its own. Researchers from Germany, Italy, the UK and Switzerland are working on this, and successful tests took place at Stuttgart airport earlier this year. €5.6 million of EU funding is invested in the system which will be available in the coming years.
In the future, more and more people will drive electric cars and will switch from one mode of transport to another – creating the need for more and varied parking options at transport hubs. To prepare for this mobility shift, the V-CHARGE consortium is working on a fully automated parking and charging system for electric cars at public car parks.
"The idea is that we can actually use technology to give people a better mix of public and private transport", explains Dr Paul Furgale, scientific project manager for V-CHARGE and deputy director of the autonomous systems lab at the Swiss Federal Institute of Technology in Zurich.
A smartphone app to leave and get back the car
Drivers will be able to leave their car in front of the car park and use a smartphone app to trigger the parking process. The vehicle will connect with the car park’s server and drive itself to the designated space. While in the garage, the car can also be programmed to go to a charging station. Upon returning, the driver uses the same app to summon the car – fully charged and ready to go.
Since GPS satellite signals don’t always work inside garages, the scientists have developed a camera-based system based on their expertise in robotics and environment sensing. Safety is at the centre of the project: the car is designed to avoid unexpected obstacles.
Dr Furgale believes the same technology could be used to develop autonomous parking systems for electric cars on city streets. "That will be more of a challenge", he says. "But once you have the maps in place, the rest of the technology will come together."
A system to be integrated into production
In April, the team presented the latest version of the system at Stuttgart airport. This was a success and the researchers are now fine-tuning the technology to tackle more precise manoeuvres and ensure reliability, even in difficult weather conditions.
The project is set to conclude in 2015, and its results available to be progressively commercialised in the coming years. The functions developed should be cost-effective enough to be integrated into production of electric vehicles. Engineers are working with equipment that is already available today such as ultrasonic sensors and stereo cameras that are used in parking assistance and emergency braking systems.
The BMW i3 has an interesting function available as a $1,000 optional extra: Parking Assistant.
This system allows your car to park itself without your input. It uses a sonar installed in the right side of the car that detects large enough parking spaces when you want it to. After that, all you have to do is stop and keep the parking assist button pressed and the i3 will do everything for you.
That’s what a crew of journalists from Romania did when BMW invited them over in Austria to try out the new electric car from Munich. However, there’s a twist: this time, no driver was inside the car while the operation was done.
The man hopping out of the moving i3 is Vali Porcisteanu, a Romanian rally driver. He somehow meddled with the control button and made it stick while he left the ‘premises’.
The end result is both quite impressive and funny at the same time, seeing the car do all the work by itself, with no one inside.
CNET On Cars, Episode 46: CNET revisits the Tesla Model S now that it's a bona fide mass production hit.
LG Chem CFO Cho Suk-jeh has revealed the company will supply an automaker with a battery that will allow one of their models to travel more than 200 miles (320 km) on a single charge. Suk-jeh declined to say which automaker will use the battery but all indications are pointing to General Motors.
General Motors executives have said that the automaker is working on an EV that will deliver at least 200 miles of range. The automaker, manufacturer of the Chevrolet Volt, has said it hopes to have the longer-range EV in the market in 2016 to compete with the anticipated Tesla Model III, now scheduled for introduction in late 2016 or early 2017.
LG Chem presently supplies lithium-ion batteries to GM, Ford, Hyundai, Kia, Volvo and Renault, among others.
Doug Parks, GM’s vice president for product development, said in an interview last year that General Motors plans to offer an EV with at least 200 miles of range for a price of around $30,000. That's the target all the major automakers are aiming at for their next-generation electric vehicles, he said.
GM invested $7 million in Battery Start-up Envia Systems in 2011. Unfortunatley the promised 'world record' 400 Watt-‐ hours/kilogram (Wh/kg) energy density only lasted a few cycles leaving GM to search for more legitimate battery technology partners.
General Motors and LG Group agreed in 2011 to jointly design and engineer future electric vehicles, expanding a relationship built on LG’s work as the battery cell supplier for the Chevrolet Volt and Opel Ampera extended-range EVs.
Kia have uploaded yet another promo video for the Soul EV.
The Soul EV will is propelled by a liquid-cooled AC synchronous permanent magnet electric motor rated for 109 horsepower and 210 lb-ft of torque. Like most electrics, the motor sends power to the front wheels via a single-speed constant-ratio transmission.
A 96-cell, 27-kWh lithium-ion polymer battery feeds the motor. It lives under the Soul’s floor, and takes a small bite out of rear seat legroom, which shrinks from 39.1 to 36.0 inches. The standard 120-volt charger, which stows under the cargo floor, takes a bigger bite out of luggage capacity, down 5.1 cubic feet to 19.1.
The Soul EV can be charged to 80% in as little as 33 minutes using a 50-kW system, and the Soul EV is fitted with three charging ports. Two of the ports are for conventional AC charging, per SAE standard J1772, and the third for CHAdeMo public stations.
Deliveries began in South Korea in May 2014 with EU and US to follow in the second half of the year. With 200 km range and a price in the $30k range it looks like a solid addition to the EV market.
