Further, when the vehicle is traveling, a battery ECU included in the charging controller is configured to maintain a charging relay in an open state (disconnected state) so that the electric power temporarily stored in the low-voltage battery is not supplied to a main battery. On the other hand, when the vehicle is traveling, the solar ECU supplies the electric power temporarily stored in the low-voltage battery to a sub-battery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charging control device using in-vehicle solar cell","description":"A solar ECU included in a charging controller is configured to temporarily store electric power generated by an in-vehicle solar cell of an electric power supply unit in a low-voltage battery when a v","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9614399","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.
