Power System Impacts of Electric Vehicles in Germany: Charging with Coal or Renewables?

, 2015
We analyze the impacts of future scenarios of electric vehicles (EVs) on the German power system, drawing on different assumptions on the charging mode. We find that the impact on the load duration curve strongly differs between charging modes.

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

Advanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior

Advanced Engineering Materials, EarlyView.
Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...
