A method for operating such an electrical energy system for a motor vehicle includes charging the high-voltage battery by using the rectifier to rectify a mains voltage and passing the rectified mains voltage on to the high-voltage battery via the direct-current converter arranged between the fuel cell and the high-voltage battery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrical energy system with fuel cells","description":"An electrical energy system includes a fuel cell, a high-voltage battery, a direct-current converter with electrical isolation arranged between the fuel cell and the high-voltage battery, and a mains ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11993158","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.
