Bosch develops electric powertrain for motorsport kart prototype together with FIA and German Motorsport Association
48-volt system makes karting emissions-free, quiet, and agile
Bosch series production technology powers the electric racing kart
“Electrification will bring more excitement, driving pleasure, and greater efficiency to motorsport,” says Dr. Markus Heyn, member of the board of management of Robert Bosch GmbH
Abstatt/Berlin – It goes from 0 to 100 kph under five seconds and has a top speed of over 130 kph, and with peak torque available even at low engine speeds, it can squeal the tires with just a tap of the pedal. The only things missing here are the engine roar and the smell of gasoline in the air. This is the motorsport experience that FIA Electric, the New Energy Commission, and the German Motorsport Association (DMSB) are presenting on May 21, 2016 in Berlin. Within the greater context of FIA Formula E they are showcasing the “e-kart”, which is a purely electric racing kart prototype. The FIA and DMSB rely on Bosch for this innovative powertrain system. The supplier of technology and services developed the system together with these motorsport organizing bodies, as well as with Germany's largest kart manufacturer Mach 1 Kart. Together these organizations will be presenting an initial prototype in Berlin. “With the e-kart, the FIA, DMSB, and Bosch are together laying the foundations for 'electrifying' performance kart racing. Just as it has on the roads, electrification will bring more excitement, driving pleasure, and greater efficiency to race tracks,” says Dr. Markus Heyn, member of the board of management of Robert Bosch GmbH. DMSB General Secretary Christian Schacht is also enthusiastic about the electric racing kart: “We're happy to support the forward-looking and exciting FIA electric kart project. As an advanced technology nation, Germany very much has a special obligation to support electromobility in motorsports. We do that with Formula E, and we also do that by supporting junior kart racing drivers.”
Powertrain technology from the street to the race track Karting is considered to be the gateway series into the world of professional motorsport. Currently, most racing karts are powered by internal-combustion engines. When the FIA, DMSB, Mach 1 Kart, and Bosch decided to develop an all-new electric powertrain for professional karting, they logically began with a blank sheet of paper. The idea was to create a purely electric motorsport discipline that made no compromises in power or performance. Bosch motorsport engineers came up with a solution in the form of the new BRS boost recuperation system, whose first generation will go into production at the company starting in 2017. The electrical components of the BRS support the internal-combustion motor in compact vehicles with up to 10 kW of additional power, which reduces fuel consumption and CO2 emissions by up to 15 percent on the street. It also provides the internal-combustion engine with an additional 150 newton meters of torque during acceleration. “We have modified the system for use in professional karting, and we are using it it to electrically power the e-kart prototype,” says Dr. Klaus Böttcher, vice president of Bosch Motorsport. “We offer a complete system combining Bosch automotive large-scale production technology with specially developed components and powertrain control software from a single source.” Two starter-generators delivering a total output of 20 kW form the basis of the new powertrain, which sends a sporting 300 Nm of torque to the rear axle. Energy is stored in the system using a 48-volt lithium battery. In addition, the starter-generators can recover energy during recuperation and then use it for acceleration. The nerve center of the powertrain is a custom ECU that controls energy flows throughout the kart. A set of sensors and a wiring harness complete the overall system. The new electric powertrain turns the Mach 1 Kart chassis into a clean, fast, and agile performer on the race track. “Even during its initial run, the electric kart was able to hit 100 kph in less than five seconds and achieve a top speed of over 130 kph. Over the coming weeks and months we will continue testing to further explore the capabilities of the new e-kart,” explains Böttcher.

Bosch Motorsport engineers equip teams running in the DTM, FIA European Formula 3 Championship, the Porsche Carrera Cup Germany, and numerous rallies and long-distance championships – including the legendary 24 Hours of Le Mans event and of course the ultimate formula racing series – with race-tested technology made by Bosch. Bosch's involvement in motor racing dates back 115 years: the first racing victories with Bosch technology on board came in the early 1900s, and the motorsport success stories continue to this day.
Stuttgart/Reutlingen – eBiking is proving very popular. For young or old, for urban or sporty use, the eBike's electric power boost makes cycling more relaxing, you travel longer distances and you reach your destination feeling fresher. What began as a niche movement has become a trend. There are 2.5 million pedelecs on German roads. Opting for an eBike is well worthwhile. To find out why that is so and how the eBike is connecting people more than it separates them, read on.
1. The environment benefits Pedelec users go easy on the environment, especially if they use their eBike on a daily basis. Half of all car journeys are 5 kilometres or less, and according to the Environmental Protection Agency the CO2 emissions of a car are around 40 times higher than those of a bicycle with a battery-powered motor. So by using an eBike rather than a car for short distances you are protecting the environment – and also travelling quietly and economically.
2. Gone are the days of headwinds Who would not on occasion have appreciated a little assistance cycling on steep ascents in a full-on headwind? An invisible “hand” to give you a gentle push and make starting on an uphill stretch or cycling on a steep ascent almost effortless. Making mountains no longer daunting and headwinds neither here nor there. The eBike makes it possible.
3. Keeps you fit, makes you mobile Are eBikes just for those who want to take it easy? Not at all! Despite the power assistance eBikers still have to hit the pedals to get moving. And it is up to you to decide how much power assistance you want or need. Studies have found that eBikers get on their bikes two to three times more often and cover much longer distances than conventional cyclists. So now is the time to get on a bike with power assistance regardless whether for comfort or for sporting use.
4. Perfect for commuting Would you like to keep fit on your commute? Then the eBike is for you. It is a sporting option. A glance at the statistics reveals that there are 30 million commuters in Germany and that nearly 25 million of them travel less than 25 km to work. Indeed, nearly every other German commuter travels less than 10 km to work. eBikes are ideal for distances of this kind.
5. Easement, exercise, extra boost Thanks to the even, adjustable assistance provided by the eBike drive system an eBike is ideal for training or for getting back into cycling after an injury. Furthermore, the drive system prevents too heavy a burden on knees or thigh muscles. That eases pressure on joints, tendons and ligaments. Would you like to be fit and healthy and to improve your wellbeing? An eBike is a step in the right direction.
6. Wheely good advice Could you do without discussions and complaints? No arguments, please? The mood can turn fast when people with unequal physical conditions and expectations set out on a cycling tour together. That is when a little motor can work wonders. Its power assistance offsets differences in performance and brings people closer together again – with the result that the tour is an experience everyone is happy to repeat.
7. Easy on the wallet eBikes are much less expensive than cars to buy and to maintain. Fuel costs, insurance premiums, car tax or parking charges? Zero. The cost of fuel alone for a diesel-powered car is currently around EUR 7.00 per 100 km. 100 km on a pedelec costs around EUR 0.25. Now that is a genuine saving. Plans already?
8. Fun factor eBikes make cycling less work and more fun. With power assistance the eBiker can sail past many other road users freely and easily. The pedelec is often the fastest mode of transport available in urban traffic over distances of up to and including 5 km – and over distances of up to 10 km eBikers can easily keep up with car drivers.
9. Pure mobility Intermodal traffic? Not the slightest problem with an eBike. eBike to the railroad station, take the train and then either use public transportation or rent a pedelec to your destination. With an eBike you are fast and flexible. You can cover distances more easily and increase the radius of distances you can travel. Power assistance gives you a real boost in the city. eBikers leave tailbacks behind them and don't need to worry about finding somewhere to park either.
10. Something for everybody The market is constantly coming up with new models and versions. Pedelecs capable of speeds of up to either 25 km/h or 45 km/h. eBikes are available for urban or cross-country use, for leisure tours or for summiteers with sporting ambitions. There is a wide range from which to choose and the right eBike for every kind of person. You really are spoilt for choice.
In 2016, DTM vehicles will once again feature Bosch engine management, displays, and other components
“DTM benefits from the motorsport expertise Bosch has built up over decades,” says Walter Mertes, Board Member for Marketing/Sponsoring at ITR
Bosch both optimizes series-production technology for motor racing and designs components especially for the DTM
Bosch has a 115-year-long tradition of involvement in motor sports – with its first racing victory in 1901
Abstatt/Hockenheim – They are rivals on the racing track, but fundamentally they all come from the same family. What race cars such as the Audi RS5 DTM, the BMW M4 DTM, and the Mercedes-AMG C 63 DTM have in common is Bosch technology. The Bosch engine management system beats like a heart under the hood, and every driver in the internationally popular DTM German Touring Car Masters series has a Bosch display before his eyes in the cockpit. “Our components precisely control engine function and ensure that drivers are able to monitor the technology. For spectators, this means exciting motorsport to the highest technical standards,” says Dr. Klaus Boettcher, vice president of Bosch Motorsport. Working with Bosch means that the DTM has a leader in technology by its side. “Bosch has been with us from the very beginning. As a supplier of technology and services it has been our trusted partner for years now,” says Walter Mertes, Board Member for Marketing/Sponsoring at ITR. “As for the components employed, we benefit as a racing series from the motorsport expertise that Bosch has built up over decades.”
Motor racing and series-production technology Ever since the new DTM began in 2000, the racing series has relied upon Bosch technology. In addition to the engine management system and displays, Bosch also supplies starters, generators, wiring harnesses, and windshield wiper direct drives. The company supplies these as standard components for every race car. These motorsport components are developed and manufactured at the development center in Abstatt near Heilbronn. This location is home to Bosch Motorsport, the Bosch group’s specialist division for motor racing technology. Its engineers are completely redesigning the DTM engine management system, display, and wiring harness. “DTM engine control units are different from those in road vehicles. That’s why DTM components are custom products, which we develop on a bespoke basis and manufacture in very small numbers,” Boettcher says. In addition to the hardware, the Bosch engine management software is also a special development aimed only at motor racing. This software allows teams to make individual adjustments in the touring cars to a wide variety of parameters such as ignition and fuel injection, within the limits permitted by DTM regulations; it also allows the teams to analyze the data from completed laps. Starters, generators, and windshield wiper direct drives are largely based on series-production technology. The motorsport engineers in Abstatt are improving the performance of these components and making them more resilient against dirt, vibration, heat, and moisture. To do this, they are collaborating closely with the prototype departments of Bosch plants in Germany and around the world. “When it comes to components, every team in the DTM benefits from Bosch’s know-how and its precision large-scale series production,” explains Boettcher.
115-year-long tradition of involvement in motor sports Bosch’s involvement in motor racing has a long tradition. The first racing victories with Bosch technology on board go back to the Nice-Salon-Nice race in 1901 and the Gordon Bennett Cup race of 1903. Back then, Mercedes race cars equipped with Bosch magneto ignition went from one triumph to the next. Another big moment came in 1954. A Mercedes Benz 2.5-liter formula race car won the French Grand Prix with a Bosch mechanical direct gasoline injection system that was being used for the first time in motorsport. A few years later, in 1965, a breakerless transistor ignition system was used in races for the first time in the Porsche 906 – and shortly afterwards, in 1968, came an experimental Antilock Braking System (ABS) in the Porsche Bergspyder. At the start of the 1980s, Bosch combined the direct gasoline injection system and ignition system to create the Motronic electronic engine control system. This was refined for Formula 1, the result of which was the World Championship title in 1983 for Brabham BMW. From 2001 to 2005, all overall winners at the 24-hour Le Mans race were using the company’s electronic direct gasoline injection system. From 2006 to 2011, all the vehicles that won on the Circuit de la Sarthe were equipped with Bosch common-rail injection systems – while in 2012 saw the first win for a diesel-hybrid race car for the first time, which also featured Bosch Motorsport technology. “Then as now, our automotive technology is successful even under the extreme conditions of motor racing,” Boettcher says. That is what his more than one hundred motorsport developers will continue working to maintain in the future, too.
Bosch Software Innovations provides charging apps, including backend infrastructure, in cooperation with automakers
The apps pool together the charging points of multiple operators
Charging apps already available for the smart and Mercedes-Benz brands, with Renault soon to follow
Apps cover some 3,700, or roughly 80 percent, of Germany's web-enabled public charge spots
By offering the ability to quickly find charging stations and pay for their use with one click, innovative charging apps are making electromobility even more practical for everyday use throughout Germany. The key to all of this is the smartphone: charging apps on the phone allow drivers of electric cars to quickly find available charging stations in their area and then use them simply and conveniently. Working together with various automakers, Bosch Software Innovations offers charging apps along with the backend infrastructure. The charging apps are currently available at no cost from smart and Mercedes-Benz, with Renault soon to follow. Around 3,700 public charging points in Germany are already accessible through the apps. The charging apps form a part of Bosch's global connectivity strategy. Soon, electric cars and their charging infrastructure will also be a part of the internet of things (IoT): “The connected electric car is the best electric car,” says Dr. Volkmar Denner, chairman of the board of management at Robert Bosch GmbH.
A key advantage of the charging apps lies in their broad scope. Approximately 3,700 of the web-enabled, public charging points in Germany have already been made accessible through the app network, and additional European countries will later follow. In addition to the technical implementation, which features services such as the intercharge eRoaming platform, Bosch Software Innovations has also signed contracts in advance with a host of charge point operators. This means that app users can conveniently use the displayed charging stations without the need for cash, and without having to resolve complex technical and contractual issues themselves before doing so. Instead, all they need is a PayPal account and to have completed a one-time registration. Even the payment process is completed from within the app in a convenient and secure fashion.
Automakers smart, Mercedes-Benz, and Renault are using the charging apps in an effort to win over more electric car customers. This is because, aside from attractive vehicle offerings, a straightforward recharging procedure plays a critical role in the continued advancement of electromobility in Germany. The operators of the charging stations profit here as well, as the apps help them to increase utilization of their charging points.
Connected charging stations represent an ideal IoT application The charging apps are an ideal example of an Internet of Things application in which intelligent objects – in this case charging stations – are connected together. With its technology, Bosch Software Innovations lays the foundation for bringing together various players such as automakers, charge point operators, energy providers, retailers, and electric car drivers on a single software platform. But what customers do not see is the powerful network of systems behind the app that are connected with one another in real time. The cloud-enabled Bosch IoT Suite software package for the development of IoT applications forms the technological basis for the charging apps. It incorporates a broad range of regional electricity and charge point providers, in addition to the intercharge eRoaming platform and the partnered services that ensure convenient payment functionality.
“With the charging apps, we are bringing the Internet of Things and electromobility together. To us this is the perfect combination, since we have been actively promoting new developments in both of these areas for several years now,” says Kai Weber, product manager at Bosch Software Innovations. Aside from its numerous e-mobility projects and its participation in the EMI³ standardizing body, Bosch's involvement also includes its roles as a consortium partner, IOT systems partner, and platform vendor for eRoaming provider Hubject GmbH in Berlin. This joint venture regularly brings together leading players in the e-mobility marketplace, for instance at the intercharge network conference in Berlin on May 12-13, 2016. During the two days of the conference, the topics of electromobility and interoperable charging infrastructure for electric vehicles will be examined and discussed extensively in keynote speeches, expert presentations, and discussion panels in the heart of the German capital.
The charge point operators are connected to the network via the intercharge eRoaming platform. An additional 700 charging points from Belectric Drive, EmiS, and E-Wald GmbH have recently been made accessible for use through the charging apps as a result. The charging apps are available both for iOS and Android operating systems.
