ANALYTICAL STUDY OF THE EFFICIENCY OF RECUPERATIVE BRAKING FOR ELECTRIC BUSES
Ilko Tarpov, Todor Lalev Nowadays, zero-emission vehicles are increasingly used in the transport systems of modern urban areas. The imposed European ment for their implementation on fifty percent of all buses by the end of 2030 and their one hundred percent use by 2060 favors them.
The selection of an electric bus is a complex technical and political process, which is accompanied by diverse ments and supported by proven methodologies for comparing various and often contradictory criteria such as price, reliability, durability and efficiency throughout the entire life cycle. There is a wide variety of brands, models, dimensions, traction battery capacity, range on a single charge, traction motor power, etc. indicators on the market, which can be seen from the catalogs of their manufacturers and compared. One of the important criteria that carriers are interested in is energy efficiency and costs during the operation period. For this reason, there is a need to assess the technical condition of an electric bus by determining the efficiency of regenerative braking and the possibility of more complete utilization of this recovered energy. The main objective of the report is to assess the efficiency and condition of the regenerative braking system by analyzing key parameters during braking. The creation of a methodology to assess the ability of an electric vehicle to recover energy during braking and return it for storage in the battery provides this opportunity for a correct assessment and comparison between different brands and models of electric buses.
