BMW and industrial companies involved in the research project “FastCharge” yesterday presented the latest advancements in the field of fast and convenient energy supply for electrically powered vehicles. The prototype of a charging station with a capacity of up to 450 kW was inaugurated in Jettingen-Scheppach, Bavaria. At this ultra-fast charging station, electrically powered research vehicles created as part of the project are able to demonstrate charging times of less than three minutes for the first 100 kilometres of range or 15 minutes for a full charge (10-80 % State of Charge (SOC)).
The new charging station can be used free of charge right away and is suitable for electric models of all brands with the Type 2 version of the internationally widespread Combined Charging System (CCS), as is commonly used in Europe.
The research project “FastCharge” is being run by an industry consortium under the leadership of the BMW Group; its other members are Allego GmbH, Phoenix Contact E-Mobility GmbH, Dr. Ing. h. c. F. Porsche AG and Siemens AG. “FastCharge” is receiving total funding of EUR 7.8 million from the Federal Ministry of Transport and Digital Infrastructure. The implementation of the funding directives is being coordinated by NOW GmbH (National Organisation Hydrogen and Fuel Cell Technology).
Fast and convenient charging will enhance the appeal of electromobility. The increase in charging capacity up to 450 kW – between three and nine times the capacity available at DC fast-charging stations to date – enables a substantial reduction in charging times. “FastCharge” is investigating the technical requirements that need to be met in terms of both vehicles and infrastructure in order to be able to tap into these extremely high charging capacities.
The basis is provided by a high-performance charging infrastructure. The Siemens energy supply system being used in the project enables researchers to test the limits of the fast-charging capacity demonstrated by vehicle batteries. It can already handle higher voltages of up to 920 volts – the level anticipated in future electrically powered vehicles. The system integrates both the high-power electronics for the charging connections as well as the communication interface to the electric vehicles. This charge controller ensures the output is automatically adapted so that different electric cars can be charged using a single infrastructure. The system’s flexible, modular architecture permits several vehicles to be charged at the same time. Thanks to high-current, high-voltage charging the system is suitable for a number of different applications, including fleet charging solutions and, as in this case, charging along highways. In order to link the system to the public power grid in Jettingen-Scheppach as part of the project, a charging container was set up with two charging connections: one provides an unprecedented charging capacity of max. 450 kW while the second can deliver up to 175 kW. Both charging stations are now available for use free of charge for all vehicles which are CCS-compatible.
The Allego charging station prototypes now presented use the European Type 2 version of the well-established Combined Charging System (CCS) charging connectors. This standard has already proved successful in numerous electrically powered vehicles and is widely used internationally.
In order to meet the demands of fast charging at high capacity, cooled HPC (High Power Charging) cables made by Phoenix Contact are used, which are fully CCS-compatible. The cooling fluid is an environment-friendly mixture of water and glycol, allowing the cooling circuit to be half-open. This makes maintenance comparatively straightforward as compared to hermetically sealed systems that use oil, e.g. in terms of refilling the cooling fluid.
One challenge was ensuring that the cooling hoses in the charging line were not squeezed when connected to the charging station, as would happen with a conventional cable gland. In the present instance this would impair the cooling flow and therefore cooling efficiency. This problem was solved by Phoenix Contact by means of a specially developed wall duct with defined interfaces for power transmission, communication and cooling as well as integrated tension relief.
Depending on the model, the new ultra-fast charging station can be used for vehicles fitted with both 400 V and 800 V battery systems. Its charging capacity automatically adapts to the maximum permitted charging capacity on the vehicle side. The time saved as a result of the increased charging capacities is demonstrated in the example of the BMW i3 research vehicle. A single 10-80 % SOC charging operation now only takes 15 minutes for the high-voltage battery, which has a net capacity of 57 kWh. This can be achieved on the vehicle side by means of a specially developed high-voltage battery combined with an intelligent charging strategy. The latter includes precise preconditioning of the storage temperature at the start of charging, temperature management during the charging operation itself and a perfectly coordinated charging capacity profile over time. The charging operation is carried out via a novel multi-voltage network on the vehicle side using a high-voltage DC/DC (HV-DC/DC) converter, transforming the required 800 V input voltage of the charging station to the lower 400 V system voltage of the BMW i3 research vehicle. The HV-DC/DC system also gives the vehicle reverse compatibility, allowing it to be charged at both old and future charging stations. A key factor in ensuring reliable operation is secure communication between the vehicle and the charging station. For this reason, standardisation issues relating to interoperability are also being investigated and submitted to standardisation bodies.
The Porsche research vehicle with a net battery capacity of approx. 90 kWh achieves a charging capacity of more than 400 kW, thereby allowing charging times of less than three minutes for the first 100 km of range.
BMW Group, Daimler AG, Ford Motor Company and Volkswagen Group with Audi and Porsche have signed a Memorandum of Understanding to create the highest-powered charging network in Europe. The goal is the quick build-up of a sizable number of stations in order to enable long-range travel for battery electric vehicle drivers. This will be an important step towards facilitating mass-market BEV adoption.
The projected ultra-fast high-powered charging network with power levels up to 350 kW will be significantly faster than the most powerful charging system deployed today. The build-up is planned to start in 2017. An initial target of about 400 sites in Europe is planned. By 2020 the customers should have access to thousands of high-powered charging points. The goal is to enable long-distance travel through open-network charging stations along highways and major thoroughfares, which has not been feasible for most BEV drivers to date. The charging experience is expected to evolve to be as convenient as refueling at conventional gas stations.
The network will be based on Combined Charging System (CCS) standard technology. The planned charging infrastructure expands the existing technical standard for AC- and DC charging of electric vehicles to the next level of capacity for DC fast charging with up to 350 kW. BEVs that are engineered to accept this full power of the charge stations can recharge brand-independently in a fraction of the time of today’s BEVs. The network is intended to serve all CCS equipped vehicles to facilitate the BEV adoption in Europe.
The vehicle built by Dutch manufacturer Terberg is used by the logistics service provider Elflein and commutes daily in the two-shift operation over a 5 kilometer distant between logistics center and the BMW group factory in Leipzig. Different vehicle components are transported, which are required for the assembly of the BMW i3 and the BMW i8 plug-in hybrid car. The electric truck is charged exclusively with electricity from renewable sources. Compared to a diesel-engined truck, the electric truck will save up to 21 tonnes of CO2 annually. Charging the truck battery takes three hours. Fully charged, the vehicle has a range of up to 80 kilometers. This means that the electric truck can complete a complete production day without additional charging.
"With our electric car BMW i3, we not only pay attention to the product, but have also aligned the entire value chain to environmental protection and sustainability right from the start. For example, we need 70% less water, 50% less energy, and 100% renewable resources to produce a BMW i3 compared to a conventional vehicle. That is why it is only logical that we now also rely on emission-free trucks in logistics and transport, "said Markus Grüneisl, Head of Logistics and Production Control at the BMW Group's Leipzig plant.
South Korea's Samsung SDI plans to invest about 400 billion won ($358 million) to build a plant to make electric vehicle batteries in Hungary, joining the race to build capacity and tap European demand.
Samsung SDI, whose customers include BMW, said on Tuesday that the proposed factory near Budapest would start production in the second half of 2018 and it would be able to produce batteries used for 50,000 pure electric vehicles (EVs) annually.
The plant will "help us save logistics costs and quickly cope with demand from customers, as European companies have manufacturing bases around Hungary," Samsung SDI, an affiliate of Samsung Electronics, said in a statement.
The company currently produces batteries for BMW's i3 in South Korea. Samsung SDI last year started production at its factory in China, the world's biggest EV market, but subsidy regulations have hampered its sales.
Cross-town rival LG Chem plans to build an EV battery plant in Poland to meet rising demand from European automakers, a person familiar with the matter told Reuters in April.
As the EV technology arms race gathers pace, the second generation BMW i8 is rumored to boost power output from it's current 350 hp to a more Tesla like 750 hp.
Automobile reports that the next-generation i8 will ditch the current i8’s three-cylinder, range-extending internal combustion engine in favor of going all-electric with three high-revving (25,000rpm) electric motors producing a total of 750 hp and more potent batteries capable of delivering a 500 kilometre range. Also part of the package are four-wheel drive, four-wheel steering, torque vectoring, and an active suspension system that scans the road ahead.
While the front axle mounted electric motor in the current i8 revs to 11,400 rpm and is mated to a 2 speed GKN transmission, using high revving electric motors could potentially allow a single speed reduction gearbox yet still achieve terminal velocity on Autobahnen.
The rumored three electric motor powertrain would have BMW only catching up to the recently launched Acura NSX. The Honda has a three electric motor torque vectoring systems with dual motors up front and combined ICE/eMotor at the rear.
Back in 2012 Mercedes demonstrated the full potential of all-wheel-drive torque vectoring with their Mercedes SLS E-Cell. By the time the next gen i8 launches around 2022-2023, a full decade after the SLS E-Cell, we can only hope BMW's next generation EV sports car at least meets if not exceeds that benchmark.
Today BMW announced that BMW i will offer a new model range of its compact electric car, the BMW i3 and from the 2017 model year will be offering a new version with more than 50% increased battery capacity. The 2017 BMW i3 (94 Ah) has a capacity of 33 kilowatt hours (kWh) thanks to the higher energy density of the lithium ion cells.
The BMW i team worked to ensure that the battery dimensions remain unchanged while still offering a significant range increase. Even in everyday conditions, the new Battery Electric BMW i3, in varying weather conditions and with the air conditioning or heating turned on, a range of up to 114 miles combined1 (hwy/city) is possible as shown by independent BMW testing cycles. The driving performance figures of the 170 hp AC synchronous electric motor remain virtually unchanged. The motor propels the BMW i3 from 0 to 60 mph in just over 7 seconds.
This makes the BMW i3 both the sportiest and most efficient electric vehicle in its segment with an expected EPA electricity consumption of 27 kWh/100mi. In addition to the Battery Electric BMW i3, the Range Extender model will also feature the 94 Ah battery. When equipped with the Range Extender, if the driver requires additional range, the 2-cylinder gasoline engine is switched on once the battery is depleted to 6.5% state of charge and keeps the charge level of the battery constant while driving and provides an additional range thanks to a 25% larger fuel tank (2.4 gallons). With the introduction of the BMW i3 (94 Ah), BMW i now also offers a new BMW Home Charger Connect, a residential charging station designed for comfortable and fast home charging featuring additional connected functions. Pricing for the 2017 BMW i3 (94 Ah) will be released closer to market launch.
Higher storage density of the battery cells.
The BMW i3 (94 Ah) sets a new benchmark in its segment with 94 ampere hours (Ah) cell capacity, 33 kWh total battery energy, and an electric range of approximately 114 miles combined1 (hwy/city) on one full battery charge. Consuming only 27 kWh/100mi the BMW i3 is the most efficient car in its segment with the lowest electricity consumption costs of approximately 2.81 USD/100mi4.
The high-voltage battery of the BMW i3 consists of eight modules with twelve storage cells each and its capacity has increased by more than 50% without any changes in exterior dimensions. By optimizing the cell-internal packages with more electrolyte and adapting the active material, BMW and Samsung SDI have succeeded in increasing cell capacity to 94 Ah and overall battery energy to 33 kWh of which 27.2 kWh can be effectively used. The previous battery of the BMW i3 (60 Ah) produced 22 kWh (gross)/19 kWh (net).
The lithium ion cells used, set themselves apart in the competitive field by achieving a special balance between high energy density, cycle stability and safety in the case of an accident. The high-voltage battery also has an advanced thermal management system that keeps the battery operating in the optimal temperature range, which further enhances performance. For example, the coolant of the air conditioning system is responsible for cooling the high-voltage battery very effectively, while a heating system can also be used to warm the battery to ensure the optimal operating temperature before starting off. Customers receive an 8-year/100,000-mile High-voltage Battery Warranty.
The BMW i3 – a benchmark in terms of sustainability
During the development phase of the BMW i3, the entire architecture of the electric drivetrain was designed with the next technological steps as well as serviceability in mind. For example, if necessary a single battery module can be exchanged which distinguishes the BMW i3 from other competitive offers and represents an integral component of the holistic BMW i concept of sustainability. From the production stand point, sustainability is achieved to a large extent through the CO2 free electricity supply of the BMW i production sites in Leipzig (assembly) and Moses Lake (CFRP production) as well as through the use of 70 percent less water in the production process compared to conventional automobiles.
Optimized performance delivery, more efficient drive.
The BMW i3 is by far the lightest car in its segment. Despite the slight weight increase, at 2,961 lbs (BEV), and 3,234 lbs (REX), the BMW i3 (94 Ah) is characterized by driving performance, which is subjectively as agile as the 60 Ah model variant. The BMW i3 (94 Ah) is also powered by the same 3 phase AC synchronous electric motor developed in-house by the BMW Group. The motor generates an output of 170 hp and delivers 184 lb-ft of torque which is available as soon as the electric motor begins to turn. The BMW i3 (94 Ah) accelerates from 0 to 60 mph in just over 7 seconds. The impressive electric motor, small turning circle of 32.3 feet, – a major benefit to driving in the city – BMW’s near-perfect 50- 50 weight distribution, precise electric power steering and the stable suspension set-up help to make the i3 as satisfying to drive as every other BMW.
The sporty character of the BMW i3’s electric motor is also clearly noticeable by its performance figure of 5.1 seconds accelerating from 50 to 75 mph. This is a decisive factor for enabling fast and safe passing maneuvers, and is normally only achieved by combustion engine powered cars with considerably higher outputs. The BMW i3 (94 Ah) is close to the level of cars such as the (320 hp) BMW 340i. Power is transmitted to the rear wheels via the single-speed transmission, which the BMW i3 uses to accelerate without torque interruption to its electronically limited top speed of 93 mph.
The electric consumption of the BMW i3 (94 Ah) has also been reduced by a large number of detail improvements including revised electric motor management as well as advanced low-resistance tires with optimized compound.
The 7.4 kW charging electronics of the BMW i3 (94 Ah) can charge the 33 kWh battery in approximately 4.5 hours using a Level 2 charger, which is slightly more than the approximately 3.5 hours required to charge the battery on a BMW i3 (60 Ah). Standard equipment of the BMW i3 includes the occasional use cable for connecting it to a domestic power socket. Core elements such as range, hallmark BMW agility thanks to low weight and overnight battery charging remain in place.
The BMW i3 is equipped with the future-proof 50 kW direct current (DC) fast charging technology. When the BMW i3 (94 Ah) is connected to a DC fast charging station, the battery cells are charged up to a minimum of 80 percent of their capacity in less than 40 minutes. In the BMW i3 (60 Ah) this takes around 25 minutes. This means that the BMW i3 (94 Ah) achieves a charging speed of 2.5 mi/min which corresponds to 24 minutes charging time per 62 miles of range.
Range Extender for even greater range.
BMW i also offers a Range Extender for the BMW i3 (94 Ah).The range of the BMW i3 is extended by a 650 cc 2-cylinder gasoline engine which is located adjacent to the electric drive above the rear axle. The Range Extender engine delivers a maximum output of 38 hp and powers a generator in order to produce electricity, working on a required-based and highly efficient principle. For those occasional times where additional range is required, as soon as the charging level of the lithium ion batteries drops to a specified level, the Range Extender kicks in to keep the charging level constant effectively extending the range. Fitting the car with the Range Extender has no influence on the available luggage volume: the luggage compartment volume remains unchanged at 15.1 ft3 and can be extended to 36.9 ft3 with the rear seats folded down. The BMW i3 (94 Ah) now features a 2.4 gallon fuel tank improving the range from the previous model.
The BMW i3 (94 Ah) with Range Extender weighs approximately an extra 270 lb compared to the Battery Electric BMW i3 but is also characterized by a high level of agility and offers impressive performance figures. It accelerates from zero to 60 mph in just 8 seconds.
New equipment on the BMW i3.
The BMW i3 (94 Ah) is now available in the exclusive Protonic Blue metallic exterior color, previously only available in the US on the BMW i8. The BMW i3 (94 Ah) customer can also choose from two non-metallic paint colors (Capparis White and Fluid Black) and, in addition to Protonic Blue, three metallic paintwork colors (Mineral Grey, Platinum Silver and Ionic Silver).
The Deka World is now part of the standard profile of the BMW i3 (94 Ah) and features a lightweight dark cloth fabric interior made from recycled materials. Other changes to the standard profile include the addition of the Universal Garage Door Opener, Advanced Real- Time Traffic Information, and Comfort Access. As part of the Tera World, a Dark Oak Wood trim is also now included, with an alternative Light Eucalyptus Wood trim available as well. These trims are also available for ordering with the Giga World.
The highly anticipated electric moonroof is also available for ordering for the first time in the US. This option features individual shades and adds to the great set of convenience features that the BMW i3 has to offer.
Standard profile and equipment for the BMW i3 (94 Ah) includes: Automatic climate control, Dynamic Cruise Control, LED Headlights, HD Radio, DC Fast Charging, Navigation Business System, BMW Assist and BMW Teleservices. Other standard features include: the iDrive operation system, the BMW i RemoteApp functionalities, the Driving Dynamic Control switch, hands-free telephone operation, leather steering wheel and Park Distance Control (PDC).
BMW i3 – a success story.
The BMW Group took on a pioneering role when it founded the BMW i brand and decided to develop an independent vehicle structure and passenger cells made of carbon fiber reinforced plastic (CFRP) as well as BMW eDrive technology for a purely electric drive. The BMW i3, which was designed for local emissions-free urban mobility, as well as the trail- blazing BMW i8 Plug-in-Hybrid sports car combined with sustainability-oriented premium character. Since the November 2013 launch, the BMW i3 has already established itself at the top of its segment. The most important single market for the purely electric five door BMW i3 is the U.S. More than 80 percent of buyers deciding on a BMW i3 worldwide are new customers for the BMW Group. The BMW i3 and the BMW i8 received a large number of awards for innovations in the areas of lightweight construction, drive, sustainability, driving performance and design. This makes BMW i the brand to win the most awards in the world during its market launch phase.
Comfortable home charging: the new BMW Home Charger Connect. In late 2016, BMW i will be offering the new BMW Home Charger Connect, a residential charging station designed for comfortable and fast home charging. The new BMW Home Charger Connect, with a more compact, sleeker design, charges the battery of the BMW i3 (94 Ah) in approximately four hours and 30 minutes. The charging process starts automatically as soon as the car and charging cable are connected. The BMW Home Charger Connect is operated using an LED interface.
The BMW Home Charger Connect comes standard with WiFi and will feature innovative charging services which can be accessed remotely. This charger helps preserve vehicle range as it can precondition the vehicle battery when connected.

The BMW i3 is equipped with the future-proof 50 kW direct current (DC) Fast charging technology. When the BMW i3 (94 Ah) is connected to a DC Fast charging station, the battery cells are charged up to 80 percent of their capacity in less than 40 minutes. In the BMW i3 (60 Ah) this takes approximately 25 minutes.
ConnectedDrive: Setting standards through Connectivity.
The optional Navigation System Professional provides BMW ConnectedDrive Services especially developed for BMW i. The range assistant follows the planned and currently driven route. If the destination selected in the navigation system is beyond the car’s range, the driver receives the suggestion to shift to the ECO PRO or ECO PRO+ mode. Additionally, the system calculates a more efficient alternative route. Should it be necessary to recharge at a public charging station, the driver is shown all the available stations along the planned route.
A dynamic range map is another central element of the connected navigation unit. Apart from the current charging status of the battery, the driving style, the activated electric comfort functions and the selected driving mode, the topographic features, the current traffic situation and the outside temperature are all taken into consideration. The Advanced Real Time Traffic Information (ARTTI) data is used for this purpose. The data is provided by the BMW ConnectedDrive Server.
The BMW i3 also sets standards when it comes to connecting driver and car. The BMW i Remote App provides useful vehicle-related mobility planning data available on the customer’s smartphone. Apart from pedestrian navigation; navigating your way to your destination from the parking space and back, BMW ConnectedDrive offers a so-called intermodal routing system and for the first time in combination with the Navigation System Professional. This also incorporates public transport connections such as subway stops if this means you can reach your destination quicker. From the actual trip in the BMW i3, looking for a parking space, changing onto a metro and or a walking route, the BMW i ConnectedDrive services take the customer to his destination efficiently.
BMW will boost the range of its i3 electric car by about half for the 2017 model year.
This summer, the lithium ion battery pack of the compact EV will be improved, "which puts it into a much more usable range," Ian Robertson, BMW AG board member for sales and marketing, told Automotive News at the Detroit auto show.
BMW doesn't have the exact figure yet, but a 50 percent increase means about 200 km on a single charge, up from the current 130 km (EPA).
The 2017 i3 will begin production in July of 2016 and will use Samsung 94 Ah battery cells. The 2017 i3 needs the increase in range to compete with the 2016 30 kWh Nissan Leaf with 250 km range and the upcoming Chevy Bolt, which will have a range of 300+ km.
The i3 went on sale in the U.S. in the spring of 2014 and has a base price of $43,350 including shipping. A model with a range extender is also available -- with about double the range -- and starts at $47,200 including shipping. Those prices are before tax credits.
BMW sold 24,057 i3s worldwide last year, an increase of 50 percent from 2014. In the United States, BMW sold 11,024 i3s, up from 6,092 in 2014. Nearly 60 percent of those were with the range extender.
German Economy Minister Sigmar Gabriel wants to commit two billion euros ($2.17 billion) to encourage more people to buy electric cars, the newspaper Die Zeit reported on Wednesday.
Buyers of electric cars would receive a subsidy from the government, the newspaper said, giving no further details.
Gabriel also wants to expand charging stations and encourage federal offices to use electric cars - an initiative that will be funded under the current German budget without tax increases, he said.
The German government aims to put one million electric cars on the roads by 2020. Among the country's carmakers, BMW, Mercedes and Volkswagen now produce all-electric cars; Audi, Mercedes and Porsche have plans to build one.
Sales of electric cars totaled some 19,000 in 2014, but at the end of 2014 Germany had only 2,400 charging stations and around 100 fast-charging points.
Calls for supporting electric cars grew at the end of last year after the Volkswagen emissions scandal. Both Gabriel and his fellow Social Democrat Environment Minster Barbara Hendricks have called for a quota for electric cars.
BMW Motorrad has a long tradition in pointing out new ways and thoughts for the topic „mobility on two wheels“. For that, again and again many studies were presented in the past giving views to the future. The experimental vehicle eRR, created as a project with the Technical University of Munich, embodies an idea of an electric powered supersport motorcycle made by BMW Motorrad.
Already a couple of years ago, BMW i showed the BMW Group’s visionary and sustainable approach with the vehicles BMW i3 and i8 and their revolutionary design principles (aluminum chassis and passenger cabin made from carbon fibre) and BMW Motorrad’s C evolution proved, that zero emission, riding fun and practicability do not exclude themselves.
With presenting the experimental vehicle eRR BMW Motorrad goes one step forward and shows the possibilities of an all-electric drive in a supersport motorcycle. Regarding design and chassis technology the eRR leans on the supersport motorcycle S 1000 RR, however using an all-electric drive.
Stephan Schaller, Head of BMW Motorrad, emphasizes: „Since their market launch, the RR is giving the creeps to motorsport athletes. If acceleration, handling or topspeed – the RR is setting standards. However, if acceleration on the first metres, up to 50, 60 kph, is the point, the RR’s 199 bhp have to admit defeat by another BMW product: the C evolution with its electric drive.
We asked ourselves: What happens when combining a sport motorcycle and an electric drive? The experimental vehicle eRR brings the topic zero emission and electric drive on a new, more fascinating level."
BMW Motorrad will announce technical details of the eRR at a later date.
