When the amount of stored electrical power at the low-voltage battery is at least a predetermined value, the control unit performs control in a manner so that the electrical power stored at the low-voltage battery is boosted by the boost unit and the bi-directional buck-boost unit, and the high-voltage battery is charged by means of the boosted electrical power."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle-mounted power source device","description":"The vehicle-mounted power source device comprising: a low-voltage battery; a high-voltage battery; a boost unit that boosts electrical power for charging the high-voltage battery; a solar panel that c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9768639","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.
