The transition to electric mobility in urban public transport is essential to address the challenges of environmental sustainability and energy efficiency in cities. This study examines the energy regeneration potential of electric buses through comprehensive analysis based on vehicle dynamics principles. Through mathematical modelling of resistive forces (aerodynamic, rolling, inertial and gravitational), taking into account urban topographical variations, the energy recoverable during deceleration and descent on slopes was quantified. The findings show that on urban routes with frequent stops and elevation changes, optimised regenerative systems can reduce energy consumption by between 15% and 25%, depending on the driving cycle and topographical configuration of the route. The methodology developed provides a robust framework for evaluating and improving regenerative propulsion systems in public transport fleets, contributing significantly to the energy optimisation of the sector.
