“…The full-active HESS solves the drawbacks of both semi-active topologies. Two main topologies exist: (a) parallel DC/DC converters topology [26] and (b) multiport DC/DC converters [27,28] as shown in Figure 2d and e, where both the battery and the SCs are connected through a DC/DC converter to an output DC link that is connected to the load [25]. The SC-stack uses its entire operating voltage range; no high power pulses are demanded from the battery because its current is well controlled, and the DC link voltage can be correctly regulated through the DC/DC converters.…”

This chapter presents hybrid energy storage systems for electric vehicles. It briefly reviews the different electrochemical energy storage technologies, highlighting their pros and cons. After that, the reason for hybridization appears: one device can be used for delivering high power and another one for having high energy density, thus large autonomy. Different energy storage devices should be interconnected in a way that guarantees the proper and safe operation of the vehicle and achieves some benefits in comparison with the single device storage system source. The chapter shows different topologies for interconnecting electrochemical technologies: passive, semi-active, and full-active, clarifying their benefits and drawbacks. The chapter concludes with a case study, an electric motorcycle, which is ridded using an urban profile. There, the hybridization was performed to extend its cycle life.
