Moreover, a detection device is provided that outputs a detection signal indicating a full-charged state of the storage battery, and a controller keeps a high-side switch in the voltage stepping-up/down circuit in an off state in response to input of the detection signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power storage apparatus with voltage stepping-up/down bi-directional converter","description":"A power storage apparatus includes a storage battery chargeable and dischargeable, a voltage stepping-up/down circuit that performs a voltage stepping-up operation of stepping up by PWM control a volt","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11522380","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.
