Abstract:
1. A multi-energy storage device system comprising: a first energy storage device coupled to a direct current (DC) link; a load coupled to the DC link and configured to receive energy from the DC link; a bi-directional buck/boost converter assembly comprising a first bi-directional buck/boost converter, the first bi-directional buck/boost converter comprising an output channel coupled to the DC link and comprising a first input channel; a second energy storage device coupled to the first input channel of the first bi-directional buck/boost converter via a first DC bus, the second energy storage device having a usable energy storage range defining an entire amount of usable energy storable in second energy storage device; a database comprising stored information related to a known acceleration event in which a supply of energy to the load is desired; and a system controller configured to: wherein the first bi-directional buck/boost converter bucks and boosts voltages received thereby so as to provide voltage to a high voltage side and a low voltage side of the multi-energy storage device system; and wherein the first energy storage device is coupled to the DC link on the high voltage side of the multi-energy storage device system and the second energy storage device is coupled to the first input channel of the first bi-directional buck/boost converter on the low voltage side of the multi-energy storage device system.
