The vehicle charging apparatus is provided with a control device 7 that controls the electric generator 3 for a charging voltage to be a target charging voltage calculated from the output voltage in order to suppress a charging current to be lower than a charging current upper limit value when the electric storage device 5 is charged. It thus becomes possible to achieve efficiency higher than that of a charging apparatus in the related art while preventing deterioration or damage of the electric storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle charging apparatus","description":"A vehicle charging apparatus includes: an electric generator 3 that is driven by an internal combustion engine 1 and outputs an adjustable alternating-current voltage; a rectifier 4 that converts the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9793749","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.
