Abstract
A system for multiple energy storage and management includes a propulsion system includes an electric drive and a direct current (DC) link electrically and a first energy storage system coupled to the electric drive. The first energy storage system includes a low specific-power energy storage device (ESD). A coupling device is coupled to a first terminal of the low specific-power ESD and a second energy storage system, wherein a first terminal of the second energy storage system is electrically coupled to the electric drive through the DC link and a second terminal of the second energy storage system is coupled to the coupling device. A boost converter assembly is coupled to the first and second energy storage systems. The coupling device couples the second terminal of the second energy storage system to the first terminal of the low specific-power ESD in a series connection that bypasses the boost converter assembly.
