The electrification of local public transport is in full swing. Building battery-operated buses and trolleybuses that combine passenger comfort with low power consumption is technically challenging. Research institutions such as the Swiss Federal Institute of Technology (Eidgenössische Technische Hochschule/ETH) in Zurich are supporting manufacturers with important findings such as the optimal use of batteries, for example. A current research project aims to improve the energy supply for heating, ventilation and air conditioning. Weiterlesen
