Design of a new On-board Energy Storage and Conversion System for a Fast Charging Urban Transport Electric Bus

Activities described in this paper concern the development of a newly urban transport solution which involves the revamping of electric bus and related fast-charge pantograph infrastructure. The sizing of the vehicle storage system in based on recorder mission profile and consumption acquired during real word testing, both in the real application scenarios and simulation environments. Optimal design relay on 5 Degree of Freedom vehicle model, for the purpose of estimating average consumption. These in formations are also useful to establish the size for the power and energy of the recharge infrastructures, which is equipped with flywheel inertial accumulators. Results show the accuracy of the developed model by comparing real and estimated energy consumption for several drive cycles, also concerning the effective route for the investigate bus line in the urban transport context.
