Pure electric bus battery pack size

Do battery electric buses need a sizing framework?

With the deployment of battery electric buses (BEB) increasing worldwide, proper battery sizing becomes more critical for operators as it dictates bus driving range and costs. In this paper, we present a battery sizing framework based on comprehensive energy needs assessment for BEB.

Are battery electric buses a viable alternative to diesel buses?

1. Introduction Battery electric buses (BEB) present the most promising alternative to replace diesel bus (DB) fleets and reduce their environmental burden [, , ], however, their massive deployment is subject to many challenges, namely the bus limited driving range and high capital costs [4, 5].

How big a battery does a bus need?

The required battery size for city bus and BRT could reach 33 kWh and 23 kWh respectively at a very high number of opportunity-charging stations (10 stations), which almost represent a 50 % decrease in battery size when compared to end-line charging, assuming the power capacity of the battery is enough to meet the bus driving cycle needs.

Why are bus batteries oversized?

Bus energy consumption and battery size are sensitive to its transit service type. City bus Batteries oversized to accommodate small number of trips during the year. With the deployment of battery electric buses (BEB) increasing worldwide, proper battery sizing becomes more critical for operators as it dictates bus driving range and costs.
