System for multiple energy storage and management and method of making same

A method of assembling a control system comprising:

• coupling an ultracapacitor with an energy battery to form a first energy storage system;
• coupling a second energy storage system to an electric drive through a direct current (DC) link;
• coupling a multi-channel bi-directional boost converter to each of the first energy storage system and second energy storage system;
• and
• connecting a terminal of the ultracapacitor in series with a terminal of the second energy storage system such that the connection between the terminal of the ultracapacitor and the terminal of the second energy storage system bypasses the multi-channel bi-directional boost converter.

An energy storage arrangement for an electrically powered system, the arrangement comprising:

• a first energy storage system comprising at least an ultracapacitor;
• a multi-channel bi-directional boost converter coupled to the first energy storage system on a low-voltage side of the multi-channel bi-directional boost converter;
• and
• a second energy storage system coupled to the multi-channel bi-directional boost converter on a high-voltage side of multi-channel bi-directional boost converter, wherein the second energy storage system is further coupled in series with the ultracapacitor such that the series connection between the second energy storage system and the ultracapacitor bypasses the multi-channel bi-directional boost converter.
