A discharge controller discharges, when a state of non-use of the secondary battery lasts for a predetermined period of time, the secondary battery such that an indicator indicating easiness of storage deterioration of the secondary battery to progress decreases in stages. The indicator includes a parameter that depends on an SOC of the secondary battery. A value of the indicator and a duration of stay in each stage are set such that a predetermined relationship holds between products in a plurality of stages, each of the products being derived from multiplying the value of the indicator and the duration of stay in each stage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery management device, battery system, and vehicle power supply system for managing battery state of charge level when in non-use state","description":"A state estimator estimates, based on at least one of a voltage, a current, and a temperature of a secondary battery, a state of the secondary battery including a state of charge (SOC) of the secondar","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11502530","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.
