<p><P>PROBLEM TO BE SOLVED: To provide a system for multiple energy storage and management and a method of making the same. <P>SOLUTION: A propulsion system comprising an electric drive, a DC link electrically coupled to the electric drive, a first energy storage system electrically coupled to the electric drive and comprising at least a high specific-power energy storage device is shown. The propulsion system further includes a second energy storage system, wherein a positive terminal of the second energy storage system is electrically coupled to the electric drive through the DC link and a negative terminal of the second energy storage system is coupled in series with a positive terminal of the high specific-power energy storage device. A multi-channel bidirectional boost converter is coupled to the first energy storage system and the second energy storage system, wherein the connection between the positive terminal of the high specific-power energy storage device and the negative terminal of the second energy storage system bypasses the multi-channel bidirectional boost converter. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
