Abstract
A vehicle propulsion includes an alternating current (AC) traction drive, a first energy storage system electrically coupled to the traction drive through a direct current (DC) link, a second energy storage system electrically coupled to the traction drive such that the voltage output from the second energy storage system is decoupled from the DC link using a bidirectional boost converter, and an energy management system configured to control said first and second energy storage systems when the vehicle is operating in at least one of a pre-charge mode and a normal operation mode with the traction drive system enabled.
Claims31
A vehicle propulsion system comprising:
- an alternating current (AC) traction drive system;
- a first energy storage system electrically coupled to said traction drive through a direct current (DC) link;
- a second energy storage system electrically coupled to said traction drive such that the voltage output from said second energy storage system is decoupled from said DC link using a bi-directional boost converter comprising a high voltage side and a low voltage side;
- and
- an energy management system configured to control said first and second energy storage systems when the vehicle is operating in at least one of a pre-charge mode and a normal operation mode with the traction drive system enabled.
