How are batteries used in the mobility industry? This three-week hybrid course introduces how batteries fit into the energy context and provides the fundamental knowledge and state-of-the-art insights into battery technologies. It will cover the key role of batteries as a tool for energy storage, the main components and parameters that characterize a battery, and the electrochemical phenomena that lie behind battery operation.

Opposed-piston two-stroke engines offer numerous advantages over conventional four-stroke engines, both in terms of fundamental principles and technical aspects. The reduced heat losses and large volume-to-surface area ratio inherently result in a high thermodynamic efficiency. Additionally, the mechanical design is simpler and requires fewer components compared to conventional four-stroke engines. When combining this engine concept with alternative fuels such as hydrogen and pre-chamber technology, a potential route for carbon-neutral powertrains is observed. To ensure safe engine operation using hydrogen as fuel, it is crucial to consider strict safety measures to prevent issues such as knock, pre-ignition, and backfiring. One potential solution to these challenges is the use of direct injection, which has the potential to improve engine efficiency and expand the range of load operation.
