The second threshold is higher by a prescribed value than a lowest allowable value of the state-of-charge at which the second battery can function as a backup power supply. The third threshold corresponds to the lowest allowable value. When determining that the conditions i), ii) and iii) are all satisfied, the ECU executes single-battery-using control in which regeneration control using the regenerative electric power is executed with use of the first battery and the second battery is not used for regeneration control."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply apparatus","description":"A power supply apparatus includes a first battery, a second battery, and an ECU configured to determine whether the following conditions i), ii), and iii) are satisfied: i) a degree of deterioration o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9815376","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.
