The electrification of public transport buses is getting more insights, especially in urban areas. The use of Battery electric buses (BEB) results in no tailpipe emissions, which gives BEB an advantage over diesel, hybrid and natural gas buses. However, the high capital costs and fluctuating operating costs of BEB limits their market breakthrough. Minimizing the total costs of BEB is essential to ease their deployment and this can be achieved by optimally designing the battery size and managing the charging strategy of the buses. These costs incur significant fluctuations as they are highly sensitive to electricity tariffs set by local authorities. In addition, these costs are directly driven by the battery costs, battery technology, and onboard energy management. For this sake, it is essential to evaluate the effect of the mentioned parameters on BEB optimal battery sizing and charging strategy and highlight their impact on the electricity grid.
