The controller manages the power chargeable to the battery on a basis of a detected value of the sensor and the upper limit charge voltage, controls the charge power on a basis of the chargeable power, sets the upper limit charge voltage to first upper limit charge voltage when the charge power is higher than a predetermined threshold value, and sets the upper limit charge voltage to second upper limit charge voltage when the charge power is lower than the threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charge control apparatus and charge control method","description":"A charge control apparatus has a charger for charging a battery with rectified power obtained by rectifying AC power supplied from a power supply by full-wave rectification or half-wave rectification ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742217","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.
