Analysis of limiting factors of battery assisted trolleybuses

The Economic Effects of Electromobility in Sustainable Urban Public Transport

“…In the context of analysing how zero-emission buses operate, it is also worth considering trolleybuses which have long been functioning in urban areas. Studies focusing on this type of buses were completed by, inter alia, Zavada et al [120], Wołek et al [121,122], or Bartłomiejczyk this type of vehicle were also obtained by Dziubinski et al [124], Grygar et al [125], and Jakubas et al [126].…”

Simulating the traction electric drive operation of a trolleybus equipped with mixed excitation motors and a DC-DC converter

“…The further impetus for the development of DC-DC converters was provided by using them in the traction drive of alternating current to ensure the connection to an energy accumulator. Study [51] analyzed the application of a DC-DC converter in public transport; work [52] explores the factors that limit the use of energy drives in a trolleybus. In fact, the DC-DC converter is used to work with the energy drive for both induction motors and DCM [53].…”

“…Urban electric transport such as subway, tram, trolleybus provides most of the intra-city passenger transportation. At present, in Ukraine, its share is (42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56) % of the total volume of passenger traffic [1]; this proportion will only increase in the future. This is explained by the fact that, given the increasing cost of fuel and the emission of carbon dioxide into the ambient air [2], the world is replacing conventional buses with electric buses (E-bus).…”

Trolleybus power supply system with high-voltage battery

“…Отже, за рахунок такої системи живлення тролейбуса підвищується його мобільність, а також усуваються пікові значення струму, внаслідок використання акумулятора [6,7].…”

“…Можемо відзначити, що рекуперація енергії має значний потенціал для економії енергії, тому під час гальмування енергія буде накопичуватися в акумуляторній батареї, а не розсіюватиметься на гальмівному резисторі, як у звичайних системах живлення тролейбусів [7].…”
