The recent Infrastructure Investment and Jobs Act (IIJA) reaffirms the decarbonizing of the transportation sector in the United States. This bill will ensure the penetration of EVs in all sectors by increasing charging station accessibility and removing barriers to further EV adoption nationwide. This mandates to investigation of all transportation sectors for EV adoption and remove the barriers. School buses are one of the largest bus networks in the USA. These buses are widely run on fossil fuels and require the execution of a variety of steps before their electrification. Before these e-school buses can be deployed at the mass level, we need to understand the energy needs and influence their fleet composition. The energy need requires a thorough understanding of each school district for their road loads (number of bus stops, trip duration, electric range, and grade profile). Typically, we see 4 types of school buses on the road these days, however, the 4 types will not be sustainable options for their electric variants, unless the whole design space is investigated for optimal sizes. Unlike diesel variants, battery holds the primary cost in the EV, oversizing it will have a significant financial impact on the school districts. Besides the road loads, the other major subsystems consuming the school bus’s energy resources are the body and dash heating and cooling loads. The bus body climate control load on the battery can impact its range and performance. These loads can impact the bus range by 50+%. This means that in winter, the same e-school bus will travel 50% fewer miles. Speaker(s): Athar Virtual: https://events.vtools.ieee.org/m/426235
