Original Abstract

This paper presents measurement results of energy balance of trolleybus regenerative braking in Brno office of public transportation. Energy storage tank (ultracapacitor or LiFePO4 battery) can be used for utilization of braking energy. Further the possibility to drive without trolley can be very useful for the office of public transportation. In this case the energy storage tank must be paced directly in the vehicle, not in the substation. Detailed measurements were performed in real trolleybus traffic on several representative routes at various work shifts. The energy balance was evaluated from the measured data. Then the energy storage tank was dimensioned (energy and power) considering both variants – ultracapacitor or LiFePO4 batteries. The results were compared each other technically and economically. Considering the ability of independent drive without trolley the solution with LiFePO4 battery is more advantageous than with the ultracapacitor.
