A multi-energy storage device system is provided that includes a first energy storage device (ESD) coupled to a direct current (DC) link. A bi-directional buck/boost converter includes an output channel coupled to the DC link and an input channel. A second ESD coupled to the input channel has a usable energy storage range defining an entire amount of usable energy storable therein. A database includes stored information related to a known acceleration event. A system controller is configured to acquire the stored information related to the known acceleration event and, during the known acceleration event, cause the buck/boost converter to boost the voltage of the second ESD and to supply the boosted voltage to the DC link such that after the known acceleration event, the state of charge of the second ESD is less than or substantially equal to a minimum usable energy storage state of charge.
