Samenvatting
The following article will analyze the benefits of retrofitting a diesel-electric bus by hybridizing its drive
train with a supercapacitor based energy storage system (ESS). Several power flow management strategies
will be proposed and compared; and their respective ESSs will be sized and designed accordingly. The
energy savings achieved range between 32 % and 40%, due to braking energy recovery and an improved
ICE efficiency, and show the importance of the power flow strategy. Results are obtained by means of a
quasi-static backwards/forward looking simulation program, developed for this purpose, which includes a
dynamic model of the ICE. Performance of the conventional bus and the hybrid bus is also compared.
