Impact of Critical Variables on Economic Viability of Converted Diesel City Bus into Electric Bus
Through the European Strategy for low-emission MOBILITY of 2016, the European Commission is working to strengthen the economy by promoting sustainable urban mobility and increased use of clean and energy efficient vehicles and looking into how to accelerate this process. Cities are crucial for the delivery of this strategy, and electrification of buses is a step towards reducing the fossil fuel dependency of the transportation sector as well as creation of a healthier urban environment.
At the same time electric buses are still a challenge for public transport operators due to high acquisition costs of a new vehicle and lack of charging infrastructure. Therefore, conversion of diesel city bus into electric bus is one of the alternatives considered. Economic viability of converted diesel bus into electric bus can be parameterized using an economic model that allows to estimate an impact of critical variables on the total cost of ownership.
In this paper, a specific case of operating converted diesel bus into electric bus in a city of Latvia is analyzed. With the help of economic model, critical variables are determined as well as their switching values, which make the use of converted diesel engine bus into an electric vehicle economically viable. It can be used to support decision-making process of public transport stakeholders in the context of the deployment of environmentally friendly public transport.
