While the solar ECU31 carries out the pumping charge, the power supply portion solar charger supplies the generated power from an in-vehicle solar cell to solar ECU31 when the power generated by the in-vehicle solar cell is a predetermined power or less, and supplies the generated power from an in-vehicle solar cell to solar ECU31 and main battery when the power generated by the in-vehicle solar cell is larger than the predetermined power. Even where the pumping charge is being carried out, the power which the in-vehicle solar cell is continuously generating can be used without being discarded futilely."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charge control device using an in-vehicle solar cell","description":"When the amount of charge of a temporary battery exceeds a predetermined amount of charge, a solar ECU31 constitutes a charge controller pumps up and boosts power stored in the battery collaborating w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9821666","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.
