A propulsion system is provided that includes an energy system, wherein the energy system comprises a first energy storage system electrically coupled to a direct current (DC) link, a bi-directional boost converter electrically coupled to the first energy storage system and to the DC link, and a second energy storage system electrically coupled to the bi-directional boost converter. The propulsion system further comprises an electric drive coupled to the DC link, an auxiliary energy source coupled to the energy system; and a system controller, wherein the system controller is configured to determine an operational status of the first energy storage system and an operational status of the second energy storage system, and if the first and second energy storage systems are determined to be non-operational, then the system controller causes energy from the auxiliary energy source to be supplied to the first energy storage system. |
