The first energy storage system comprises a high specific-energy storage device and the second energy storage system comprises a low specific-power storage device. The propulsion system also includes a third energy storage system comprising a high specific-energy storage device electrically coupled to the second energy storage system. A bi-directional boost converter is electrically coupled to the second and third energy storage systems such that a terminal of the third energy storage system is electrically coupled to a low voltage side of the bi-directional boost converter and a terminal of the second energy storage system is coupled to a high voltage side of the bi-directional boost converter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for multiple energy storage and management and method of making same","description":"A propulsion system includes an electric drive, a first energy storage system electrically coupled to the electric drive through a DC link, and a second energy storage system electrically coupled to t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9809128","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
