Mercedes Developing Electric Vehicle Platform

Mercedes-Benz is in the early stages of developing a new platform to underpin a range of electric vehicles.

The platform, tentatively called Ecoluxe, is part of an ambitious €2 billion project that Mercedes executives are allegedly about to approve. The guidelines call for a platform that is light in order to offset the bulk of the battery pack and modular so that it can underpin both long and short wheelbase vehicles. Mercedes is currently planning on building four body styles on the Ecoluxe platform, though additional variants could be added later in the production run.

German magazine Auto Bild reports that all cars built on the Ecoluxe platform will feature rear-wheel drive and an innovative four-wheel steering system. The first model, which has not been given a name yet, will pack the equivalent of 544 horsepower in standard S form or 603 hp in GT tune. A high-capacity battery pack located under the passenger compartment will give the car a maximum driving range of at least 450 km.

The first model underpinned by the Ecoluxe platform is scheduled to hit the market in either 2019 or 2020

Daimler to spend 100 million euros to expand German battery output

Daimler will spend about 100 million euros (US$125 million) in coming years to increase production of lithium-ion battery packs in eastern Germany.

The German automaker said on Monday it will expand capacity at Deutsche ACCUmotive, its battery-making division in Saxony as it expects "high and steadily-growing demand" for electric-car batteries.

The unit supplies batteries for the luxury Mercedes division's hybrid S-Class, E-Class and C-Class models, Daimler said.

Steps to increase battery output tie in with Daimler's plans announced last month to phase out production of lithium-ion battery cells at its second Saxony-based Li-Tec division by the end of 2015.

Daimler aims to employ the bulk of Li-Tec's 250 workers at Deutsche ACCUmotive.

The Stuttgart-based manufacturer in future plans to buy battery cells from LG Chem.

Asian makers of battery cells such as Samsung, Panasonic and LG Chem are producing the cells at lower costs, reaping benefits from scale effects as they're also serving non-automotive industries, analysts said.

Germany exits EV Battery Cell Manufacture Business

The only German factory that produces battery cells for electric cars is closed. Little more than one year, the company Li-Tec in Saxon Kamenz will manufacture battery cells. The company is a subsidiary of the Daimler Group.

"Our cells are very good, but at current production figures too expensive", the Daimler-manager Harald Kröger justified the closure in an interview with SPIEGEL. Last week, Daimler had 250 employees internally announced the end of the factory, more than half should be able to remain in the group. Only mass production makes such factories profitable. Therefore, it was part of the Daimler-calculus that other auto companies participate and would leave produce in Kamenz cells for their e-Mobile. But the partners did not materialize.

Now the company changes its strategy. "We have realised that a car manufacturer does not have to produce the cells themselves," says Kroeger.

Li-Tec will be retained as a research location; the majority of the 280 employees will be transferred to the Deutsche Accumotive—also a wholly owned Daimler subsidiary—which manufactures battery packs. Accumotive is currently expanding its production capacity to build systems for the next generation of the electric smart among others. Cells are slated to come from LG Chem.

Remember, in urban driving top speed means nothing, it's the first 5 meters that count!

Mercedes-Benz S 500 Plug-In Hybrid goes on sale

The Mercedes-Benz S 500 PLUG-IN HYBRID can be ordered for prices from 108,944.50 euros[1]. The S 500 PLUG-IN HYBRID blends an ultramodern hybrid drive configuration with the unique innovations and the luxurious equipment and appointments of the S-Class. The luxury saloon with a long wheelbase impresses with unique dynamism and efficiency. Thanks to standard pre-entry climate control it also offers unique climate comfort. In September the first certified three-litre luxury saloon in the world will be arriving at the dealers - a further milestone on the road to emission-free mobility.

"The new S 500 PLUG-IN HYBRID offers our customers the entire range of innovations that make our new S-Class so successful, and thanks to its intelligent operating strategy ensures outstanding driving pleasure and dynamism combined with the highest efficiency. Moreover, it allows completely emission-free driving for up to 33 km," says Ola Källenius, Executive Vice-President for Sales at Mercedes-Benz Cars.

"The S 500 PLUG-IN HYBRID is the first luxury saloon with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate highest efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and hybrid drive," says Prof. Dr. Thomas Weber, member of the Daimler AG Executive Board responsible for corporate research and Mercedes-Benz Cars Development.

The Mercedes-Benz S 500 PLUG-IN HYBRID offers a system output of 325 kW and 650 Nm torque, and in just 5.2 seconds sprints from 0 to 100 km/h and can drive up to 33 km purely electrically. The certified consumption is 2.8 litres/100 km, which corresponds to 65 g CO2/km emissions. Key elements of this impressive output are the V6 biturbo and the intelligent hybrid drive. Following the S 400 HYBRID and S 300 BlueTEC HYBRID the S 500 PLUG-IN HYBRID is the third hybrid model in the new S-class. Its new high-voltage lithium-ion battery can be externally recharged via the charging socket in the right side of the rear bumper.

In order to strengthen the customers' trust in the new, innovative PLUG-IN HYBRID drive system, for the S 500 PLUG-IN HYBRID Mercedes-Benz is for the first time issuing a certificate and thus a promise to perform for the high-voltage battery and PLUG-IN HYBRID components (e.g. e-machine and power electronics). This ensures that every technical malfunction within a period of six years after initial delivery or registration, or up to a mileage of 100,000 kilometres, is corrected by Mercedes-Benz.

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.

Aero Comparo! Tesla Model S vs Volt, Prius, Leaf, Mercedes [VIDEO]

Car and Driver gathered five slippery cars to study their drag and lift properties at a wind tunnel to determine which brand did the best job optimizing its car’s aero performance.

The overall winner was the Tesla Model S by virtue of its larger 25.2-square-foot face and lower 0.24 drag coefficient, which yield the same 6.2-square-foot drag area as the Prius. Low drag is a tougher challenge with a larger frontal area, hence the Tesla’s overall win.

Test driving the new Mercedes B-Class electric Drive [VIDEO]

For the first time, Mercedes brings a fully electric car to the U.S

The B-Class ED is the product of a technology-sharing alliance between Tesla and Daimler that goes back to Mercedes’ 2009 investment.

Rather than rely on in-house R&D, Mercedes essentially contracted with Tesla—the Silicon Valley car maker and acknowledged leader in electric automobiles—to provide the EV architecture (motor, transmission, battery, power electronics) for its electron-fired B-Class.

Tesla will make the B-Class battery pack, power management system etc at the factory in Fremont, Calif., and ship them to Germany for final vehicle assembly.

The B-Class Electric Drive, which is built on the same production line as the gasoline-powered version, is going to go on sale in Europe around the end of the year and will also come in a right-hand drive version for other markets in 2015.

One of these days, one of these compliance cars is going to break out, sales-wise. The B-Class ED, which will sell in all 50 states, could be the one. While it might have emerged out of a compliance effort, the B-ED just shines, a premium family electric that braids Tesla’s and Mercedes’ DNA so convincingly the car might as well be called the Model B.

Mercedes-Benz B-Class Electric Drive Priced From $41,450

The all-new 2014 B-Class Electric Drive features dynamic design, a premium interior and a powerful electric motor for emission-free mobility. This allows for lively, effortless driving pleasure over a real-world range of 85 miles (EPA)*. In addition, the B-Class Electric Drive is digitally networked. Thanks to its connectivity, it can be conveniently checked and configured via the internet. As the Mercedes-Benz among electric vehicles, the B-Class Electric Drive sets clear standards in terms of comfort, quality and safety for up to five occupants. The B-Class Electric Drive, bearing the unmistakable three-pointed star trademark, will first be launched in the US market in the summer of 2014.

The new B-Class Electric Drive surprises with an especially dynamic driving experience. It provides noticeably powerful acceleration, while gliding along quietly. The new electric Mercedes offers the driver and up to four passengers the familiar high standards of ride comfort in a high-class, spacious and precision-designed interior. The B-Class Electric Drive combines dynamic and driving pleasure with zero local emissions – in short: it delivers electric driving at premium level.

Powerful drive with brisk acceleration

The new Mercedes-Benz B-Class Electric Drive is based on the conventionally powered B-Class, for which the current generation has become a bestseller since being launched in many countries in 2011. Since the launch of the first B-Class version in 2005, Mercedes-Benz has seen customers taking delivery of over one million of these vehicles. As an especially versatile vehicle concept, the B-Class with its innovative electric drive now allows additional environmental friendly capabilities to Mercedes standards.

Mercedes-Benz has collaborated with TESLA Motors to develop the electric B-Class. The two companies share many years of cooperation in the field of electric mobility. The battery for the predecessor model of the smart fortwo electric drive, for instance, came from TESLA. For the B-Class Electric Drive, Mercedes-Benz is once again leveraging the extensive know-how available from the electric car pioneer and is using the TESLA drive system in its own vehicle.

Quiet and local emission-free driving is ensured by an electric motor generating 177 hp (132 kW). Typical for an electric drive system, the motor develops its maximum torque of 251 lb-ft (340 Newton meters) from the very first touch of the accelerator. This is approximately equivalent to the torque from a modern three-liter gasoline engine. The result is noticeably powerful acceleration from a standing start. The electrically driven B-Class drives from zero to 60 mph in 7.9 seconds. Effortless drivability and exhilarating driving pleasure with a high level of comfort are thus guaranteed in every situation.

The power supply to the electric drive is delivered via a highperformance lithium-ion battery, which is compactly and safely housed in the “Energy Space” in the underfloor of the vehicle. Such intelligent packaging allows the five-seater to retain the B-Class’s familiar spaciousness in both its interior and its luggage compartment of 17.69-51.42 ft3.

Zero emissions also on longer journeys

In the interests of optimizing range, the top speed is electronically limited to 100 mph. Depending on driving cycle; the vehicle has a range of 85 miles (EPA)*. This permits emission-free driving not just in city traffic and on short journeys, but also over longer distances – such as a daily commute. The B-Class Electric Drive can be charged from any standard domestic power socket. For a range of 60 miles, the charging time at 240V in the United States is less than 2 hours*. On the road, the electric drive itself makes its own contribution to a favorable energy balance by converting kinetic energy into electric current during coasting and braking, and feeds this energy into the battery.

Dynamic Mercedes-Benz design

Refined sportiness combined with aesthetic appeal – the B-Class Electric Drive features the self-assured and dynamic styling so typical of Mercedes with powerfully defined lines and finely crafted details. The front and rear sections express the width of the vehicle. This is ensured by the wide, prominent grille and the headlamps, which wrap round into the sides, as well as by the wide rear window, two-piece tail lights and large tailgate with deep sill. A dynamic look is created by door-sill panels and striking bumpers with bar-shaped LED daytime running lamps. The charge socket is inconspicuously installed behind the conventional fuel door.

Sporty interior with classy touches

The interior underscores the high standards of comfort typical of Mercedes-Benz. High-grade materials and finely textured surfaces, classy touches and precision workmanship make it clear that Mercedes-style electric drive is defined by high standards.

The three large round center air vents with their uniquely styled cruciform nozzles add a sporty flair that contributes to the overall emotive design idiom of the interior. Positioned above the air vents and seemingly free-floating is the screen for the telematics system – a state-of-the-art eye-catcher in the cockpit.

In terms of information and communication systems, the electric B-Class offers levels of comfort and functionality that is customary of any Mercedes-Benz. The standard equipment package includes a head unit with 5.8 in (14.7 cm) color display, twin tuner and MP3- Page 4 compatible CD player as well as USB port. The Becker® MAP PILOT is the standard navigation system while the COMAND multimedia system with internet access, navigation and LINGUATRONIC voice control is also optionally available.

The instrumentation of the B-Class Electric Drive is rounded off by functions that are specific to electric vehicles. One of the striking features is the power display in the right-hand circular instrument. The instrument pointer moves in a clockwise direction from the green zone towards the red zone, when full power is demanded by the driver. It drops back below the zero line when the vehicle is feeding energy into the battery through the recuperation feature.

Ideally networked: connected services

Thanks to its state-of-the-art technology, the B-Class Electric Drive is not just sustainable and agile, but also connected. For example, the Vehicle Homepage allows convenient remote interaction and remote configuration of the vehicle. The driver can use their PC or smartphone to conveniently access the vehicle via the internet. It is possible, for instance, to determine the current state of charge of the lithium-ion battery or show the vehicle’s current range on a map. In addition, the planned route can be displayed, showing at a glance where the vehicle can be recharged along the way, should this prove necessary. The range of connected services is rounded off by a feature that allows individually timed pre-heating or cooling of the vehicle. This pre-entry climate control system makes the B-Class Electric Drive unique in its segment.

Big on safety

Mercedes-Benz applies its familiar, high safety standards to the BClass Electric Drive. Thanks to the innovative “Energy Space”, the battery is safely accommodated in the underfloor of the vehicle, where it is ensured protection in the event of a crash. In addition, Mercedes-Benz has equipped this innovative electric car with the radar-based collision warning system COLLISION PREVENTION ASSIST with adaptive Brake Assist as standard. This assistance system gives the driver a visual and audible warning of detected obstacles, prepares them for braking action and assists them with the braking process as the situation requires. In this way, it significantly reduces the danger of a rear-end collision. Additional cutting-edge driver assistance systems are also available, including Blind Spot Assist, Lane Keeping Assist and Active Parking Assist.

Electric drive made by Mercedes-Benz

Locally emission-free electric vehicles such as the new B-Class Electric Drive are a key part of Mercedes-Benz’s strategy for sustainable mobility. The Stuttgart-based premium manufacturer is asserting its claim to leadership in this sector with electric vehicles that are fully suitable for everyday use. Mercedes-Benz aims to strengthen its position in future, not least with the new BClass Electric Drive, which will be available initially in the USA as of mid of 2014, before subsequently being launched in European markets.

Daimler-BYD Unveil All-Electric DENZA with 300 km range

BYD Daimler New Technology Co., Ltd. (BDNT) officially unveiled its DENZA all-electric vehicle at Auto China 2014, in Beijing. The world premiere of the serial production model is the culmination of cooperative efforts at the 50:50 R&D technology joint venture established by Daimler and BYD back in 2010 – the first Sino-German joint venture dedicated to an all-electric vehicle in China. Combining Daimler’s renowned tradition and engineering expertise as a worldwide leader in safety technology and quality excellence with BYD’s leading battery technology, DENZA is styled as an honest and modern urban vehicle concept that fits both private and fleet customers.

“Daimler is constantly moving forward with emission-free mobility; and with our DENZA we are also on the right track in China, which is destined to become the world’s most important market for electric vehicles“, said Hubertus Troska, Member of the Board of Management of Daimler AG with responsibility for China, and Chairman and CEO of Daimler Greater China. “With DENZA we deliver the safest, most reliable, and most convenient electric vehicle to our Chinese customers – designed, engineered, and produced in China, for China, once again proving our full commitment to the country.”

DENZA has been designed around its lithium iron phosphate battery which is framed by a lightweight aluminium case with extrusion profiles. Designed to absorb large amounts of energy, it is located at the safest place in the car - underneath the body. The layout also ensures that all powertrain components are separated from the passenger compartment. Additionally, DENZA’s intelligent Power Flow Management System constantly monitors the energy flow between the battery and powertrain to guarantee that, in the event of an accident, the battery is disconnected automatically and, if needed, quickly discharges to levels below critical values.

As a forerunner in electric vehicle safety, BDNT worked closely with China’s official safety certification body, CATARTC, to jointly develop an electric vehicle safety standard for China. By also considering real life accident data, DENZA has gone even further than these legal requirements to ensure that its customers enjoy the highest level of safety.

“DENZA is the first complete vehicle that Daimler has developed together with BYD outside of Germany and it is undoubtedly one key pillar of Daimler’s electric vehicle strategy in China“, noted Prof. Thomas Weber, Member of the Board of Management of Daimler AG responsible for Research and Development. “No compromises have been made to design and develop, in China, an all-electric car that raises the bar in its segment. We assure our Chinese customers the highest standards of safety, paired with maximum convenience, outstanding reliability and unique driving fun as part of a superior overall concept.”

The DENZA has been put through 18 months of intensive testing that saw various cars drive over 1.2 million kilometres across all of China under extreme and various weather and road conditions – be it hot, cold, dusty or icy. This testing program, which looked at overall quality and endurance, was complemented by additional component testing and crash test programs. In total, BDNT crashed more than 20 cars, including high-speed, low-speed and rollover-scenarios. DENZA also became the first electric vehicle to be tested according to C-NCAP consumer ratings at C-NCAP facilities, obtaining the highest possible rating of 5 stars.

It goes without saying that the quality of the production is secured at a modern, independent production line in Shenzhen, following Daimler’s proven production philosophy and quality control methods.

With a driving range of up to 300 kilometres, the DENZA offers the ease and convenience of emission free mobility for day-to-day use – in urban areas, and beyond. Charging the battery is highly flexible, as it can be done at any household power outlet, public charging facilities or special wall boxes. The latter of which can be installed at homes or in offices at the request of DENZA customers, guaranteeing fast charging, ranging from seven hours to less than an hour. With the DENZA app, available for both Android and iOS phones, wall box customers can even remotely check on their charging status and vehicle location using their smartphones and, if needed, get connected right away to a dealership or customer service centre.

DENZA clearly aims to change mobility, but not the mobility behaviours of its customers. That is why, thanks to its luxury class level wheelbase, it can comfortably accommodate up to 5 passengers, with ample legroom and an inviting 460 litre trunk volume. The roominess of the interior is complemented by a clean, functional design and high craftsmanship.

DENZA’s package is convincing, and so is its heart, the electric powertrain and battery technology. The vehicle is powered by an 86 kW (peak) all-electric engine that provides a maximum speed of up to 150 km/h and impressive peak torque, at 290 Nm. Together with its big 47.5 kWh battery capacity, and a convenient suspension, customers can rest assured that they can enjoy both maximum driving fun and comfort with a range of up to 300 km. In light of the fact that the average daily driving distance in China is 50 to 80 kilometres a day, the typical customer will only have to recharge DENZA twice a week. This bi-weekly pit stop will be met with joy as driving 100 km with a DENZA cost less than 20 RMB (2,35 EUR). All this classifies the DENZA as the perfect vehicle for day-to-day use – in urban areas, and beyond.

Wang Chuanfu, Chairman of BYD Company Limited, stated: “With our DENZA, I see my vision come true as we make big steps towards sustainable development in and for China. Backed by a supportive government and the win-win alliance between BYD and Daimler, and its Chinese heart, DENZA offers a convincing package to our Chinese customers, pointing the way and contributing strongly to the development of the electric vehicle market in China.”
