1. 1. Decarbonizing Public Bus Transport – a case study on Curitiba, Brazil

   University essay from KTH/Energi och klimatstudier, ECS

   Author : Joana Lena Düllmann Vasques Pereira; [2018]
   Keywords : Battery electric bus; Brazil; Charging station; Curitiba; Greenhouse gas emissions; Opportunity charging; Optimisation; Public transport network; Brasil; Carregamento de oportunidade; Curitiba; Estação de recarga; Gases com efeito de estufa; Ônibus eléctricos a baterias; Otimisação; Sistema de Transporte Público; Batteribuss; Brasilien; Laddstation; Curitiba; Växthusgas utsläpp; Opportunity Charging; optimering; kollektivtrafik;

   Abstract : Air pollution is becoming a major issue in cities across the world, its common cause being the use of fossil fuel combustion engines in both private and collective transport modes. However, alternative technologies, such as biofuels, hybrid and battery electric vehicles, are on the rise. READ MORE

3. 2. Current Ripple Simulation in DC Traction Voltage System of an Electric Bus: 2

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Filip Gard; Linda Nilsson; [2017]
   Keywords : Current Ripple; LTSpice; Simulation; Measurement; Volvo; Electric vehicle; Electric bus; Technology and Engineering;

   Abstract : Current ripple can cause a lot of problems as it spreads in the DC-side of the TVS of electric and electric hybrid vehicles. Fully knowing the properties of the TVS can be used to build a simulation model to determine the spreading of current ripple beforehand, which in turn is useful for calculating component placement, optimal filter sizes, and component lifetime.

4. 3. Current ripple simulation of the electric system of an electric bus

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Christian Lugnberg; David Wenander; [2017]
   Keywords : Electromobility; electric propulsion system; current ripple; hybrid vehicles; simulation model; power electronics; LTspice; Technology and Engineering;

   Abstract : With effect of global warming and climate change the electrification of vehicles enables a more sustainable and environmentally friendly alternative to conventional vehicles as it reduces toxic emissions and overall energy consumption. Different extents of electrification is today used. Hybrid and electric vehicles are two examples. READ MORE

5. 4. Assessing the potential of fuel saving and emissions reduction of the bus rapid transit system in Curitiba, Brazil

   Abstract : The transport sector contributes significantly to global energy use and emissions due to its traditional dependency on fossil fuels. Climate change, security of energy supply and increasing mobility demand is mobilising governments around the challenges of sustainable transport. READ MORE

6. 5. Alternative cost-optimal pathways for the transport sector of Cyprus

   University essay from KTH/Energisystemanalys

   Author : Josefin Wiking; [2015]
   Keywords : energy systems analysis; modelling; MESSAGE; Cyprus; transportation sector; freight transportation; passenger transportation;

   Abstract : This thesis investigates the possible future pathways for the road transportation sector of Cyprus, in a time horizon from the year 2013 to 2040. The road transportation sector of Cyprus is the most energy consuming sector in the country, completely dependent on the use of diesel and gasoline. READ MORE
