What is e-mobility?

Electric Mobility is Reforming the Automotive Industry Conventional mobility with vehicles powered by internal combustion engines is to be replaced by electric mobility. A battery-powered vehicle does not produce any local emissions and therefore has a positive tank-to-wheel balance.

Electric Mobility is Reforming the Automotive Industry

The automotive industry is in a state of upheaval. Battery-powered electric vehicles that use electricity from sustainable resources are the best solution for reducing global greenhouse gas emissions and pollution caused by particulate matter and noise. However, their success will depend to a great extent on the creation of a charging infrastructure and adaptations to vehicle architectures.

Only by abandoning the use of fossil fuels will it be possible to achieve a significant reduction in greenhouse gas emissions and pollution caused by particulate matter and noise. Conventional mobility with vehicles powered by internal combustion engines is to be replaced by electric mobility. A battery-powered vehicle does not produce any local emissions and therefore has a positive tank-to-wheel balance. What is more, vehicles that do not have an internal combustion engine generate considerably less noise pollution than conventionally powered vehicles.

However, this positive overall environmental balance depends on how the energy is generated. If the electricity does not come from regenerative resources such as solar or wind power, but from conventional coal-fired, gas-fired, or nuclear power stations, the environmental balance is negative. In fact, even higher emissions are generated per mile driven. A further negative factor from the well-to-wheel perspective is the CO2-intensive production of the lithium-ion batteries that are required.

The Challenge of Electric Mobility

Making electric mobility attractive not only for everyday driving but also for long-distance travel will require the development of powerful batteries with a high capacity. Only then will it be possible to achieve acceptable driving ranges of more than 500 km with an electric car. Furthermore, the lithium-ion batteries must be mass-produced at a lower cost than is currently the case. After all, the drive battery is currently the key reason why the purchase price of electric vehicles is still high.

Also required are comprehensive thermal management concepts to optimally control all energy flows in the vehicle. Only these can resolve the conflicts between range and interior comfort. This is particularly true when it comes to utilizing the battery power regardless of the weather conditions. For example, driving at temperatures below freezing point requires completely new heating concepts in order to avoid reductions in the driving range of the electric motors.

The Electric Vehicle as a Virtual Power Plant

A further challenge for electric mobility is the rapid creation of a nationwide infrastructure of electric charging stations, particularly regarding the charging period and the type of charging involved. Charging must be rapid and simple if it is to result in the necessary level of acceptance among customers who are considering buying an electric car. Fast charging stations and inductive charging systems offer the necessary potentials here. It is particularly important to further advance vehicle connectivity in order to guarantee optimum and efficient range analysis with fast charging cycles in real time. What is more, the additional energy requirements and the impact on peak loads caused by large-scale electrification must not be underestimated, and these can only be ensured by further power stations or storage systems for volatile wind and solar energy.

Otherwise, there is a risk that an increase in electric mobility will result in supply bottlenecks at the distribution level. Electric vehicles can be integrated into an intelligent electric grid (vehicle-to-grid) as flexible consumers and peak load storage systems, thus sustainably optimizing the distribution network. Bidirectional charging is a key step towards electrified mobility. Intelligent control systems and power electronics are required. A further requirement is to synchronize the development and marketing of electric vehicles and the charging infrastructure.

Shift in Expertise in Development and Production

The impact of electric mobility can be seen not only in a change in energy requirements, but also in the technology of the vehicles themselves. It will involve profound changes to vehicle structures and components. Electric powertrains require completely different types of expertise. The proportion of electric and electronic components in particular will rise dramatically, to 75 %. And other systems too, such as the body, the interior, and the chassis, cannot simply be taken over from conventionally powered vehicles, but must be specially adapted.

What is more, depending on how the vehicle is to be used, different requirements regarding efficiency, cost, and performance must be taken into consideration. On the other hand, the substitution of the internal combustion engine, the fuel tank and other components required for conventional vehicles will provide new degrees of freedom in vehicle design. That is extremely important particularly in the context of urban mobility.
