New Tech Promises to Boost Electric Vehicle Efficiency, Range

Researchers at North Carolina State University have developed a new type of inverter device with greater efficiency in a smaller, lighter package – which should improve the fuel-efficiency and range of hybrid and electric vehicles.

Electric and hybrid vehicles rely on inverters to ensure that enough electricity is conveyed from the battery to the motor during vehicle operation. Conventional inverters rely on components made of the semiconductor material silicon.

Now researchers at the Future Renewable Electric Energy Distribution and Management (FREEDM) Systems Center at NC State have developed an inverter using off-the-shelf components made of the wide-bandgap semiconductor material silicon carbide (SiC) – with promising results.

“Our silicon carbide prototype inverter can transfer 99 percent of energy to the motor, which is about two percent higher than the best silicon-based inverters under normal conditions,” says Iqbal Husain, ABB Distinguished Professor of Electrical and Computer Engineering at NC State and director of the FREEDM Center.

“Equally important, the silicon carbide inverters can be smaller and lighter than their silicon counterparts, further improving the range of electric vehicles,” says Husain, who co-authored two papers related to the work. “And new advances we’ve made in inverter components should allow us to make the inverters even smaller still.”

Range is an important issue because so-called “range anxiety” is a major factor limiting public acceptance of electric vehicles. People are afraid they won’t be able to travel very far or that they’ll get stuck on the side of the road.

The new SiC-based inverter is able to convey 12.1 kilowatts of power per liter (kW/L) – close to the U.S. Department of Energy’s goal of developing inverters that can achieve 13.4 kW/L by 2020. By way of comparison, a 2010 electric vehicle could achieve only 4.1 kW/L.

“Conventional, silicon-based inverters have likely improved since 2010, but they’re still nowhere near 12.1 kW/L,” Husain says.

The power density of new SiC materials allows engineers to make the inverters – and their components, such as capacitors and inductors – smaller and lighter.

“But, frankly, we are pretty sure that we can improve further on the energy density that we’ve shown with this prototype,” Husain says.

That’s because the new inverter prototype was made using off-the-shelf SiC components – and FREEDM researchers have recently made new, ultra-high density SiC power components that they expect will allow them to get closer to DOE’s 13.4 kW/L target once it’s incorporated into next generation inverters.

What’s more, the design of the new power component is more effective at dissipating heat than previous versions. This could allow the creation of air-cooled inverters, eliminating the need for bulky (and heavy) liquid cooling systems.

“We predict that we’ll be able to make an air-cooled inverter up to 35 kW using the new module, for use in motorcycles, hybrid vehicles and scooters,” Husain says. “And it will boost energy density even when used with liquid cooling systems in more powerful vehicles.”

The current SiC inverter prototype was designed to go up to 55 kW – the sort of power you’d see in a hybrid vehicle. The researchers are now in the process of scaling it up to 100 kW – akin to what you’d see in a fully electric vehicle – using off-the-shelf components. And they’re also in the process of developing inverters that make use of the new, ultra-high density SiC power component that they developed on-site.

A paper on the new inverter, “Design Methodology for a Planarized High Power Density EV/HEV Traction Drive using SiC Power Modules,” will be presented at the IEEE Energy Conversion Congress and Exposition (ECCE), being held Sept. 18-22 in Milwaukee. Lead author of the paper is Dhrubo Rahman, a Ph.D. student at NC State. The paper was co-authored by Adam Morgan, Yang Xu and Rui Gao, who are Ph.D. students at NC State; Wensong Yu and Douglas Hopkins, research professors in NC State’s Department of Electrical and Computer Engineering; and Husain.

A paper on the new, ultra-high density SiC power component, “Development of an Ultra-high Density Power Chip on Bus Module,” will also be presented at ECCE. Lead author of the paper is Yang Xu. The paper was co-authored by Yu, Husain and Hopkins, as well as by Harvey West, a research professor in NC State’s Edward P. Fitts Department of Industrial and Systems Engineering.

The research was done with the support of the PowerAmerica Institute, a public-private research initiative housed at NC State and funded by DOE’s Office of Energy Efficiency and Renewable Energy under award number DE-EE0006521. FREEDM, a National Science Foundation Engineering Research Center, is aimed at facilitating the development and implementation of new renewable electric-energy technologies.

Real-driving emissions (RDE)

Brussels, 19 January 2016 – Following the debate on real-driving emissions (RDE) during the plenary session of the European Parliament in Strasbourg yesterday, the European Automobile Manufacturers’ Association (ACEA) reiterates that it fully agrees with the need for emissions to more closely reflect real-world conditions.
“We urgently need to have a new test method to bridge the gap between the current laboratory testing of pollutant emissions, as defined by law, and the very different conditions experienced on the road,” said Erik Jonnaert, ACEA Secretary General. Alongside other stakeholders, ACEA has therefore been contributing constructively to the efforts of the European Commission and member states to develop a robust RDE test.

During the October meeting of the Commission’s regulatory committee (TCMV) a tough compromise was agreed on RDE with testing standards that will be extremely difficult for automobile manufacturers to reach in a short space of time, and highly challenging targets in a second step. The TCMV also agreed that the RDE conformity factor should be reviewed in the future.

“Despite the challenges in the latest proposals, the industry urgently needs clarity now so manufacturers can plan the development and design of vehicles in line with the new RDE requirements. Any delay to this legislation would leave little time to make the necessary changes and ultimately would just push back the benefits for the environment,” stated Jonnaert. “Our industry needs the RDE test to restore the confidence of consumers and legislators in the environmental performance of new vehicles.”

Death by EV

Some automotive technicians are going to be killed by the high voltages on electric vehicles. I have written many textbooks about automotive technology where I have highlighted safe working practices, but the one I have just completed the script for will save lives. This book is called, ‘Electric and Hybrid Vehicles’, and will be out early in 2016. By the way, we use the term EV to cover all the different types there are such as hybrids and pure-EVs.

Did you know the voltages on some EVs can be several hundred volts, which is almost three time the mains voltage in our houses? The majority of EV batteries are well over 300 volts. If the human body experiences a current of just fifty thousandths of an ampere (50mA, which is not very much) for over two seconds it can be fatal.

Now that I have scared you away from ever touching high voltage components (which are all labelled and usually coloured orange) I would add that working on EVs is perfectly safe! You just need to be trained and know what you are doing. Driving an EV is also perfectly safe and don’t expect poor performance either. My EV will do well over 80 miles per hour (on a private track!) just using the battery and electric motor.

Of course as well as saving lives, the book is packed with really interesting information and technology relating to EVs. For example, whether it is safe to plug in the charging lead in the rain. How most motors on EVs are AC motors but we call them DC motors! The book even covers things like what ‘first responders’ should do if a lithium-ion battery is burning after an accident. The book covers all the requirements for the Institute of the Motor Industry (IMI) awards and accreditations for those who need a qualification. Look out for the amazing eLearning that will also be available soon to support the book.

I have also included a short case study on charging my own EV (actually a PHEV) from solar panels. This may or may not save the planet but in the meantime it does save me money as I can now do a large proportion of my motoring for about 1p a mile.

Here are three more interesting facts to finish on:

A formula-e (fully electric racing car) will accelerate from 0 to 100 kilometres per hour in under 3 seconds

  • The Tesla Model S (a fully electric car) has a range of up to 330 miles
  • In the year 1900, electrically powered cars were the best-selling road vehicles in the USA

Now back to the final proof read of the script!

ICE, PHEV or Pure-EV

(Internal Combustion Engine, Plug-in Hybrid Electric Vehicle (like my GTE!) or a pure Electric only Vehicle)

I have been playing around with a few figures relating to the overall costs of running these three different vehicles and trying to compare them – it is a difficult task! Here is what I have done so far, comments and ideas are welcome:

=========================

The cost of charging an EV battery depends on the size of the battery, how depleted the battery is and how quickly you charge it. As a guide, charging a pure-electric car from flat to full will cost from as little as £1.00 to £4.00. This is for a typical pure-EV with a 24kWh battery which will offer around 100 miles range.

This means the average cost of ‘fuel’ will be approximately £0.03 per mile. Similar costs will apply to PHEVs and E-REVs, and because the batteries are smaller, it will cost less to charge them. See also the figures in table 2.

In some cases it may be possible to charge overnight and take advantage of cheaper electricity rates. Other options include charging from domestic solar panels. At this time it is calculated that the total cost of ownership of an electric car is similar to an ICE because of the additional purchase costs. However, this will change and if other advantages are included such as congestion charges (currently £11.50 per day in London for ICE but zero for EVs), the EV will be significantly cheaper in the longer term.

Table 1 Comparison of costs

Term, mileage, fuel cost ICE Pure-EV PHEV Notes
Annual mileage 10,000 10,000 10,000
Cost of fuel (£/gallon or £kW/h) £5.70 £0.05 £5.70 / £0.05 Electricity (£/kWh) average standard/cheap/solar used for calculation
Official combined cycle mpg 68 mpg 150 Wh/km 166 mpg Electricity consumption (Wh/km)
‘Real world‘ mpg 50 mpg 175 Wh/km0.28 kWh/mile 100 mpg *1 Real world consumption
Total fuel costs £1,140 £140 £570 (annual miles * fuel cost / mpg)(annual miles * fuel cost * kWh/mile)
Vehicle cost information        
Purchase price £28,000 £34,000 £35,000 Estimates based on current list prices
Plug-in car grant -£5,000 -£5,000 A grant to reduce cost by 25% (up to £5,000)
Net purchase price £28,000 £29,000 £30,000
Depreciation cost/year £8,400 £8,700 £9,000 30% used – this will vary however
Residual value £19,600 £21,300 £21,000
Service, maintenance and repair £190 £155 £190 Based on average of published figures.
Other information        
Vehicle Excise Duty and Registration Fee £30 £0 £0
TOTAL COST £9,760 £8,995 £9,760 Per year

Important note: the figures used in this table are ‘best guesses’ but none-the-less give a reasonable comparison. The bottom line is that the three cars have broadly the same overall total cost even though the Pure-EV and the PHEV have much lower fuel costs. The key factor will be how the depreciation cost of the EVs pan out. However, over subsequent years the fuel savings associated with the EVs will become more significant.

Being able to programme EVs to charge during the night will allow drivers to take advantage of cheaper electricity prices, whilst using any surplus electricity. In addition, the development of smart metering systems which can automatically select charging times and tariffs can also help to manage demand on the grid. The National Grid manages the grid on a second by second basis to ensure that supply and demand are met and to indicate to the market if there is a shortfall or surplus of power.

Free motoring…

…we’ll almost, at least very cheap motoring is the plan!

On the 7th August 2015 I took delivery of the (almost) final part of the puzzle that when put together will result in big savings – I hope. I still need to get the proper charging point together with gadgets to monitor energy use etc., but I am nearly there. Here is my new Golf GTE (from Inchcape in Chelmsford) taking its first charge on my drive:

image
Golf GTE – one of the first in my region

The Golf GTE 1.4 TSI produces 204PS (Pferdestärke, abbreviation of the German term for metric horsepower).  It is a PHEV (plug-in hybrid electric vehicle) 5dr DSG boasting 0–62mph in 7.6 seconds. and up to 166.0 mpg. The electric range is 31 miles and when electric and petrol combine, the total range is 580 miles. The previous data are laboratory figures of course, I will report back on what happens in the real world in due course. However, its performance is very impressive so far. Because the car is a plug-in hybrid it attracted the £5000 government grant. More on overall prices later though because cheap mileage is all very well but initial and running costs still have to be considered.

The other part of my cunning plan involves solar panels (actually photo-voltaic or PV panels) and these will be used to charge the 8.8 kWh lithium-ion battery in 3.75 hours from a domestic mains outlet, or 2.25 hours from a domestic wallbox.

PV panels (a 4kW array) fitted in February (the snow being the clue)
PV panels (a 4kW array) fitted in February (the snow being the clue)

My PV array has saved me buying a lot of electricity and has further resulted in an income. So far this year I have received about £400, by selling the excess energy back to the grid (using what is known as a feed-in tariff). In addition, my electricity bill has reduced as shown in the following chart:

Comparison of grid power used with solar generated and last year's average use (09/08/2015).
Comparison of grid power used with solar generated and last year’s average use (09/08/2015).

As you would expect, we pay much more for the electricity we use than the price we get when selling it (something like 14p per unit when buying and 3p per unit when selling). The way the feed-in tariff works is that the electricity generation company pays us for 50% of the amount generated by the PV panels. So the more we generate the more we get but of course the other advantage is gained because the more of the PV energy we use, the less electricity we purchase. This is where the new car comes in. The plan is that whenever we return home, we will make sure all the available charge in the car’s lithium-iron (Li-on) traction batteries has been used up. This will simply be done by switching the car to full e-mode when 35 miles from home. The car will now only be charged when enough solar energy is available (emergencies excepted of course). I am doing this manually at the moment but it will be automated in due course.

I have just completed a journey, by pure coincidence, to the UK VW headquarters where they have a charge point (well they should have shouldn’t they)! This was about a 170 mile round trip for me. I set off with a fully charged battery and managed to add 20 miles worth of charge while I was there. The car trip computer showed an overall average mpg of 68 – so just under 2.5 gallons. for the journey. My previous car (a modern Golf GTD 2.0ltr) would have done the same at an average of about 48 mpg (about 3.5 gallons). This journey was a good combination of country roads and motorway so probably indicates a good average. I did not try to save fuel or equally I didn’t accelerate/brake rapidly so the figures are probably quite a good start for real-world use. When used in hybrid mode only, the average was about 50 mpg .

I am expecting to win much more on the shorter journeys we do, which will use no petrol or very little. My journey to the office at the IMI for example, is about 42 miles each way. We have a free charging point! My hope therefore is to only use about half a gallon of fuel for the return trip (60 miles on full electric and 25 miles at 50 mpg).

Watch this space, more details to come…

Internet of ‘car-things’

Cars still have their best days ahead of them. Connecting vehicles to the internet makes them safer, more fun to drive, and reduces fuel consumption. In the future, this Bosch technology will provide real-time information about mobile construction zones, traffic jams, and accidents. On this basis, further improvements to existing functions such as start-stop coasting will be possible. At the same time, it will enable a predictive operating strategy for plug-in hybrids. Technologies such as this reduce CO2 emissions by up to 10 percent or more.

The reductions to consumption brought by start-stop coasting and an optimum operating strategy are most noticeable in real traffic conditions. In the New European Driving Cycle (NEDC), however, they have no effect. Using up-to-date maps, cars can precisely calculate their remaining range in addition to the most efficient route. At the same time, intelligent connectivity increases the suitability of electrified vehicles for everyday use. In only ten years, more than 15 % of new vehicles worldwide will be electrified. Of these, more than 13 million new vehicles will be able to run on electricity alone, at least in urban traffic.

Technically-sophisticated components make vehicles more economical and efficient, allowing them to meet the strict CO2 targets set by the European Commission. European regulations stipulate that in 2021, new vehicles will be allowed to emit an average of only 95 grams of CO2 per kilometre. This corresponds to just over four litres of fuel consumed per hundred kilometres. In 2013, new vehicles emitted an average of 132.9 grams of CO2 per kilometre. The EU recognizes especially environmentally-friendly technologies as “eco-innovations.” Automakers can use these as CO2 credits to reduce their fleet consumption levels. The maximum possible credit is 7 grams per kilometre.

Facts about battery technology for hybrid and electric powertrains

How range is increasing, why a battery has more than one lifetime, and how automated driving could change battery technology

Long service life, top quality, the highest degree of safety – we expect an enormous amount from high-voltage batteries in vehicles. That’s why today’s lithium-ion batteries, for example, have to be designed to run for at least 150,000 kilometers and to last up to 15 years. Even then, after spending all this time in the car, the battery still has to possess 80 percent of its original storage capacity and performance. “Developing a high-voltage vehicle battery that is cost efficient, powerful, and reliable at the same time – this is the proverbial rocket science,” says Dr. Joachim Fetzer, the member of the executive management of the Gasoline Systems division of Robert Bosch GmbH responsible for electromobility. Within the next five years, Bosch intends to offer high-voltage batteries that are twice as powerful. At the same time, the company is exploring new battery technologies.

Development: the path to the next generation of lithium-ion batteries

Lithium-ion technology: In the years to come, lithium-ion technology still has plenty of potential to offer. Today’s batteries have an energy density of approximately 115 W h/kg, but have the potential to go as high as 280 W h/kg. To research the next generation of lithium-ion batteries, Bosch has joined forces with GS Yuasa and Mitsubishi Corporation in a joint venture called Lithium Energy and Power. “The goal of this joint venture is to make lithium-ion batteries up to two times more powerful,” Fetzer says. In pursuit of this goal, the partners have pooled their strengths. GS Yuasa can apply its experience in cell optimization to creating a battery with a higher energy density and increased range. Bosch contributes its expertise in complex battery management and systems integration.

Post-lithium-ion batteries: Bosch’s corporate research department is working on post-lithium-ion batteries, such as those made using lithium-sulfur technology, which promises greater energy density and capacity. Bosch estimates that the earliest the lithium-sulfur battery will be ready for series production is the middle of the next decade.

Progress: battery management results in 10 percent more range

Cell chemistry: There are several ways to improve battery performance. For example, the material used for the anode and cathode plays a major role in the cell chemistry. Most of today’s cathodes consist of nickel-cobalt manganese (NCM) and nickel-carboxyanhydrides (NCA), whereas anodes are made of graphite, soft or hard carbon, or silicon carbon.

Cell voltage: High-voltage electrolytes can further boost battery performance, raising the voltage within the cell from 4.5 to 5 volts. The technical challenge lies in guaranteeing safety and longevity while improving performance.

Battery management: In terms of high-performance batteries, Bosch is focusing on driving forward the monitoring and management of the various cells as well as the overall system. The challenge is managing a high-voltage battery reliably, since up to ten microcontrollers regulate energy flow in the cells by means of a CAN bus system. Sophisticated battery management can further increase the range of a car by up to 10 percent – without altering the cell chemistry.

Infrastructure: automated vehicles have an effect on battery technology

Rapid-recharging charge spots: If there are lots of places where you can quickly charge your electric vehicle, then this will have a major impact on battery technology. The faster an electric vehicle’s battery can recharge, the less important its range becomes.

Automated driving: Fully automated vehicles make charging much more straightforward, since they can search for charge spots without any assistance from the driver. How this works is demonstrated by V-Charge, a project spearheaded by Bosch, VW, and a number of European universities. The idea is that within a parking garage, for instance, the driver would be able to use a smartphone app to direct their electric vehicle to a charge spot. When the driver comes back, the car returns to the pick-up spot by itself. Other variations on this theme are also possible; for example, a driver could request a vehicle from a car-sharing fleet by cell phone and have it come right away to a designated spot. Fleets are in fact another area where demands on the battery – such as those regarding its service life – are changing, since fleet vehicles are often in service for fewer than the 15 years estimated for vehicle batteries.

Three lifetimes: for a high-voltage battery, the car is just the first step

Different stages in the life of a battery: A fleet vehicle, which drives many kilometers in a short space of time, requires a new battery with full performance and capacity. In contrast, a slightly used battery can work just as well in cars that are driven only occasionally for short routes. That would reduce the overall cost of an electric car. Even after twelve years – the average service life of a car – the battery still retains 80 percent of its original performance and capacity. This means its components can still be useful, for example as a power storage unit.

“Second Life” project with BMW and Vattenfall: In Hamburg, used batteries from electric vehicles are being joined together to form a large power storage system. It can provide energy within seconds and helps stabilize the grid. With this project, Bosch, the BMW Group, and Vattenfall are working together to drive electromobility and energy storage forward.

Toyota Motor Europe wants its batteries back

  • With 91% of its hybrid batteries being successfully collected through its own retail network, Toyota Motor Europe (TME) is now extending collection to independent end-of-life vehicle (ELV) treatment operators
  • TME aims to collect 100% of Toyota and Lexus customers’ used hybrid batteries, both through its own network and any authorised ELV operator across Europe
  • As part of its plans to realise this ambitious objective, TME has extended until March 31, 2018 the current battery recycling agreements with France-based Société Nouvelle d’Affinage des Métaux (SNAM) and Belgium-based Umicore N.V., responsible for the European-wide take back and sustainable recycling of nickel-metal hydride (NiMh) and Lithium-ion (Li-ion) batteries in Europe, respectively

Brussels, Belgium – Hybrid batteries can generally outlast the vehicle life. These are therefore usually only recovered at the end of the vehicle life or in case of an accident. TME has built up years of experience running an internal collection process with Toyota and Lexus retailers/repairers through a reverse logistics mechanism. Toyota and Lexus dealers receive a new hybrid battery in return for giving back the old one, leading to an average 91% collection rate.

Now TME is stepping up efforts to drastically increase the volumes of collected used hybrid batteries. It set itself the challenging target of aiming to collect 100% of the batteries, coming from both its own network and from any authorised ELV treatment operators across the whole of Europe.

That is why the company announces today the extension, until March 31, 2018, of the current battery recycling agreements:

  1. Since 1 July 2011 France-based Société Nouvelle d’Affinage des Métaux (SNAM) has been taking back and recycling nickel-metal hydride (NiMh) batteries in Europe (installed in the Prius, Auris Hybrid, Auris Hybrid Touring Sports, Yaris Hybrid and all Lexus hybrids)
  2. Since 20 August 2012 Belgium-based Umicore N.V. has been taking back and recycling Lithium-ion (Li-ion) batteries in Europe (installed in Toyota’s Prius+ and Prius Plug-in)

Steve Hope, General Manager TME Environment Affairs, says “When our customers buy a hybrid, they already know that they are in for outstanding fuel efficiency, a stress free driving experience and a reliable car.” He continues “This is yet another reason for a hybrid purchase. We ensure customers that their car excels in environmental performance during its entire lifecycle, giving customers another good reason to fall in love with hybrid.”

“Today used hybrid batteries are still mainly destined for recycling”, adds Steve Hope. “However, TME has started to research the different options for the remanufacturing of NiMh batteries.” Solutions include giving those batteries a second life as vehicle-to-vehicle or vehicle-to-stationary energy source.

Since 2000, around 850,000 Toyota and Lexus full hybrid vehicles have been sold in Europe. A cornerstone in Toyota’s environmental approach is the protection of natural resources, making sustainable recycling of high voltage batteries a key priority.

“Electric cars are good, but connected electric cars are better”

Says Bosch CEO Denner at Car Symposium 2015

  • Dr. Volkmar Denner: “Electrification will take combustion engines to new heights”
  • Falling battery prices will halve costs by 2020
  • E-bike as model: Europe’s most successful electric vehicle is about enjoyment

Powertrain electrification is picking up pace. The currently low oil price will not change that fact. This was the message underlined by Dr. Volkmar Denner, chairman of the board of management of Robert Bosch GmbH, at the Car Symposium in Bochum, Germany. Bosch expects roughly 15 percent of all new cars built worldwide to have at least a hybrid powertrain by 2025. For the Bosch CEO, advances in battery technology are the key to lower vehicle prices. Denner, whose responsibilities on the board of management include research and advance development, believes that by 2020 batteries will deliver twice as much energy density for half the present cost.

Electrification enhances the attractiveness of combustion engines
The EU has set strict fleet CO2 targets for 2021. For this reason alone, Bosch expects hybrid powertrains to become the standard for SUVs. This will give diesel and gasoline engines an extra boost. “Electrification will take combustion engines to new heights,” Denner said. With electric support, the combustion engines of the future will consume significantly less fuel and be even cleaner. And the additional torque from the electric motor will add to driving enjoyment. Moreover, falling battery prices will make hybrids considerably more affordable.

Denner used the example of China to show how important it is in a mass market for electric cars to be suitable for everyday use. There are already more than 120 million electric scooters on China’s roads. And in China, Bosch sells the electric wheel hub drive for such e-scooters. With a top speed of 40 kph, this popular form of transport is fast enough for the traffic conditions in megacities.

And their range of roughly 50 kilometers is sufficient for everyday journeys. “The reason these two-wheelers are such a success is that they are a perfect match for Chinese commuters’ needs,” Denner said. And because they are designed to meet these needs, many models are less expensive than two-wheelers with combustion engines. According to Denner, the task now is to make such tailor-made solutions possible for cars as well.

One app to recharge the battery, nationwide
The main factor helping to make electromobility convenient will be connecting vehicles with the internet of things. “Electric cars are good but connected electric cars are better,” Denner said. At the moment, recharging vehicles is complicated. But this is expected to become much more convenient. Bosch Software Innovations, the Bosch Group’s software and systems unit, has developed an app that makes it significantly easier to reserve the charge spots of different providers and pay for the electricity. Up to now, doing this would have required a different customer card for each provider. Now all drivers need is a smartphone, the app, and a PayPal account to recharge anywhere in Germany. Bosch also complements this with a software platform that links 80 percent of all charge spots in Germany. As this example shows, Bosch no longer sees itself solely as a supplier of automotive components. The company is now combining its expertise in all three mobility domains – automation, electrification, and connectivity – and will in the future be offering its customers integrated mobility solutions.


However, rational arguments alone are not enough to win drivers over to electric powertrains. In Bosch’s view, emotion and fun play a decisive role. The example of e-bike drives illustrates this. Bosch’s “electric tailwind” makes riding a bike a joy – for serious athletes as well as recreational cyclists. Bosch is now the European market leader in this area, and its e-bike drives feature in more than 50 bike brands. “The e-bike is the most successful electric vehicle in the EU,” Denner said, adding that customers pay considerably more on average for e-bikes than they do for classic ones. “For more than 100 years, riding a bike was a mechanical process. No one saw any reason to change it. Then along came the e-bike, and completely redefined a market everyone thought would never change,” Denner said. The same could be true for the auto industry, he added. The Bosch CEO stressed that the supplier of technology and services will be using its comprehensive systems and connectivity know-how to take electromobility a decisive step forward.
