1. Sustainable Urban and Regional Development and Related Ecosystem Services and Water-Climate Interactions
Sammanfattning : To accommodate a growing global population while mitigating climate change, urban areas must grow while minimising environmental impacts. To achieve this, a city must be treated as a complex socio-ecological system in which many actors and subsystems act in unclear and unpredictable ways. LÄS MER
2. A Two-Stroke Range Extender Engine For Heavy Duty BEV applications
Sammanfattning : A back-up range extender (REX) is proposed to support battery electric vehicles (BEV) for heavy duty applications. A single cylinder crank case scavenged two-stroke SI-internal combustion engine (ICE) with a turbocharger system is considered powerful and small enough to be installed directly on the existing electric machine in the electric powertrain.

3. Car movement patterns and the PHEV
Sammanfattning : Roughly 30% of Sweden’s total greenhouse gas emissions originate from transport and a majority of them from cars. The plug-in hybrid electric vehicle (PHEV) avoids the range limitation of the fully electric vehicle while still allowing for a major share of the fuel to be replaced by electricity from the grid and can thereby reduce greenhouse gas emissions, local pollutants and energy security concerns.

4. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles
Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER
5. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure
Sammanfattning : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. LÄS MER
