BMW, Daimler Jointly Developing Wireless Inductive Charging Standard

Driving pleasure and sustainability are fused together in unprecedented fashion in the all-electric BMW i3 and the BMW i8 plug-in hybrid sports car. Their high-voltage batteries can be recharged quickly and easily by means of the BMW i Wallbox that forms part of the 360° ELECTRIC portfolio. This sophisticated charging station with fast-charge facility for feeding cars with power either at home or at work underlines the all-embracing approach adopted by the BMW i brand when it comes to developing products and services for sustainable mobility of premium calibre.

In the process, the BMW Group has assumed a pioneering role in this field and is therefore pressing keenly ahead with the development of innovative technologies for making driving with zero tailpipe emissions more and more attractive. Systems for inductive charging of high-voltage batteries are the next step forward for energy supply. The development objective in the medium term is to put reliable, non-wearing and user-friendly solutions for inductive charging into production that have been tailored to both the batteries in the BMW i cars and the high-voltage batteries in future plug-in hybrid models from the BMW Group.

The crucial advantage of inductive power supply over conventional charging stations is the cable-free connection between the supply point and the vehicle’s high-voltage battery. Carmakers Daimler and the BMW Group have signed an agreement on the joint development and implementation of a standardised technology for inductive charging of electric cars and plug-in hybrid vehicles. The system consists of two components: a secondary coil in the vehicle floor as well as a base plate with integral primary coil that is located underneath the car, for example on the garage floor. The arrangement of the coils, and consequently of the field pattern, is based on a design derived from their circular shape that offers a number of crucial benefits.

These include the extremely compact and lightweight construction along with effective spatial confinement of the magnetic field. The electrical energy is transmitted via an alternating magnetic field generated between the coils, contact-free, without charging cables and at a charging rate of 3.6 kW. With an efficiency factor of over 90 percent, this method enables the high-voltage batteries in vehicles to be charged efficiently, conveniently and safely.

A further development target is to minimise the charging time for contactless power transmission. At a charging rate of 3.6 kilowatts, the high-voltage batteries in many plug-in hybrid vehicles can be fully charged in under three hours. It takes less than two hours to charge the BMW i8 using a fully working prototype of an inductive charging station. In order to make allowance for the higher storage capacities of high-voltage batteries in pure-electric vehicles, the future technology standard also foresees the possibility of increasing the charging rate to 7 kW. This ensures that the battery in the BMW i3 could still be fully charged overnight when using the inductive system.

Inductive charging makes life considerably easier for the driver of an electric or plug-in hybrid vehicle, as there is no need to connect any cables to top up the power reserves. Once it has been correctly positioned above the primary coil, the driver can simply start the charging process at the push of a button using the vehicle’s own operating system. Data is transmitted via a WiFi connection between vehicle and charging station to help the driver even with parking.

The inductive charging facility can be used regardless of the weather conditions. Not even rain or snow has a negative effect on the power feed as all of the system’s conductive components are protected, which means the primary coil can even be installed outdoors. During charging, ambient electromagnetic radiation is also kept to an absolute minimum. The space between the primary and secondary coils is permanently monitored, allowing charging to be halted instantly if any foreign bodies are detected.

As with today’s BMW i Wallbox, the inductive power supply systems of the future will also make it possible to activate and monitor the charging process from a smartphone. The relevant smartphone app will let drivers call up the data transmitted online on the battery’s charge status, for instance, or the time remaining until charging is complete.

Mitsubishi MiEV Evolution III Wins Pikes Peak Electric Division & 2nd Outright

Mitsubishi Motors Corporation (MMC) entered two MiEV Evolution III all-electric racecars, which combine the best of MMC's electric vehicle (EV) and four-wheel drive control technologies, in the Electric Modified Division of the 2014 edition of the world-famous Pikes Peak International Hill Climb (Pikes Peak, June 23 to June 29) in Colorado, United States.

Race Day was held on Sunday June 29 and after posting the fastest time of 9 minutes 08 seconds 188, Greg Tracy won the Electric Modified Division honors and 2nd overall. Meanwhile, Hiroshi Masuoka set a time of 9 minutes 12 seconds 204, finishing 2nd in the division and 3rd overall, dominating the Electric Modified Division. These Race Day results and the performance of the cars during the event speak volumes about the advanced level of MMC’s EV and four-wheel drive control technologies.

The race starts at an elevation of 2,862 meters and takes competitors through 156 corners on a 20 km course to the finish on the 4,301 meter summit of Pikes Peak. With an elevation difference of 1,439 meters, atmospheric pressure, temperature, weather and other conditions vary significantly between the start and finish. A feature of the race course is that it is split into three major sections: Bottom at the foot of the mountain, Middle and then Upper near the summit.

Lined by coniferous trees, the Bottom section starts with its rhythmical series of mid- to high-speed corners but all of a sudden the drivers hit a series of much tighter and difficult turns which demand the utmost care and concentration.

The Middle section is distinguished by some spectacular scenery with oddly-shaped rocks closely bordering the road. This is a very technical section as shortly after the start a series of tight hairpin bends demand precise handling as the car races along the steeply ascending road.

The Upper section is a very high-speed course taking competitors through many fast corners between craggy rocks and boulders. With little guard railing at the side of the road, this very difficult section brings with it the risk of plunging over the edge should the car slide off the tarmac. This is why the highest levels of vehicle stability are required over the high-speed parts of the section. At 4,301 meters, the mountain summit is higher than Mt. Fuji and the thin air means that cars powered by internal combustion engines lose power the higher up they go. Electrically powered cars, however, are unaffected by the thin air and so this could prove the key section in setting a really fast overall race time.

BMW i3 with F1 Technology [VIDEO]

BMW i3 is one of many cars that now come equipped with F1 technology. The carbon fibre reinforced plastic (CFRP) Monocoque is used to reduce weight and ensure road safety.

The extensive use of carbon fibre keeps the curb weight down to 1,195 kg which is much lower then either a Nissan Leaf (1,500 kg) or a plug-in hybrid like the Chevy Volt (1,700 kg).

When combined with the i3's 125 kW BLDC electric motor, which is more powerful than either the Leaf (80 kW) or the Volt (110 kW), the result is a 0-100 km/h time of 7 seconds.

Driving Tesla Model S P85 on German autobahn [VIDEO]

Norwegian Tesla owner Bjørn Nyland has uploaded a video demonstrating his Model S at Autobahn speeds.

A Tesla Model S P85 driven at it's maximum speed of 210 km/h (130 mph) has an estimated range of 154 kms (96 Miles)

Having recently returned from Munich I can vouch for the fact that driving at 160 km/h (100 mph) in the fast lane is considered slow, they really do drive at 200 km/h routinely on unlimited sections, yet the road toll is actually lower than in many other countries (including Australia).

Audi Plans Range of High-Performance Electric Cars

Audi has drawn up blueprints for a wider range of high-performance electric cars to help it take on German rivals and U.S. firm Tesla Motors, according to sources at the carmaker.

Tesla has managed to stay ahead of the pack with new technology, which has extended driving range and reduced costs. Its success and the excitement about BMW's new "i" electric series have caught the attention of Audi, which some analysts have said risks looking like a laggard in an industry where innovation is a major draw for customers.

Audi, a unit of Volkswagen, is about to launch its first purely electric car, a battery-powered version of its R8 supercar, which is due to hit European dealerships in 2015. It will offer a driving range of 450 km (280 miles), close to the 502 km of Tesla's top-selling Model S luxury saloon.

Meanwhile, Audi has scaled up its electric car plans, having devised blueprints for several high-performance electric saloons and sport-utility vehicles, two company sources told Reuters, asking not to be identified because the matter is confidential.

VW declined to comment. Audi did not return calls seeking comment. The manufacturer has shown various hybrid and purely electric concept cars since about 2009, but the latest blueprints stand a bigger chance of getting the nod for production after it lately overcame range limits.

"Germany's major carmakers all have their electric car plans ready in the drawer," Hanover-based NordLB analyst Frank Schwope said. "They want to be prepared when demand accelerates," he said. The sources at Audi did not specify how many models were being planned or the scale of any production plans.

They said, however, that one of the blueprints is for an electric version of a new Q8 SUV that would pit the brand against Tesla's forthcoming Model X. Audi has defined a range target of about 400 km for any future electric model it aims to develop, the sources said.

Audi's plans will be helped by steps underway to upgrade a production platform dubbed MLB that already underpins larger models across the VW group, such as the Audi A8 saloon and Porsche Cayenne SUV, and would cut costs for electric cars.

INNOVATIONS

Sales of electric cars are expected to surge to 2.7 million globally by 2018 from 180,000 last year as more models come to market, battery costs fall and the number of charging stations grows, according to business consultancy Frost & Sullivan. While mid-market battery cars such as the Renault Zoe and Nissan Leaf have missed sales targets, there has been more buoyant demand for premium offerings. Germany's three leading luxury carmakers are all advancing on the electric market.

Rival BMW has launched its "i" series of electric models, including a 34,950 euro ($47,400) city car, while Mercedes, whose parent Daimler owns a 4.3 percent stake in Tesla, started production in April of its B-Class electric compact.

Tesla has devised innovations that have cut the cost and raised the safety of battery packs. Its models also recharge more quickly than those of rivals, thanks to its connectors, software and efficient power management.

But the California-based company is now facing its own challenges related to scaling up further after its success. It said last week it would share its patents with competitors in hopes of speeding up development of electric cars across the industry.

Tesla executives have also met counterparts from BMW to discuss ways to promote electric cars which analysts say must include steps to create a common infrastructure and share the cost of building recharging stations.

Audi's electric-car moves highlight a change of tack at VW. In 2012 Audi shelved the R8 e-tron at request of its parent as efforts to expand the model's driving range had stalled at only 215 km.

Audi, which has since swapped R&D chiefs, has overcome the range limits by increasing the efficiency of the electric drivetrain and curbing on-board power consumption, development chief Ulrich Hackenberg has said.

"Electric mobility is a key focus of our development strategy," he said in March. "We are ideally prepared for the future with our strategic roadmap and a well-filled development pipeline."
