The apparatus includes a collecting device that collects information regarding the slope or the road type and information regarding the vehicle speed. A controller determines charge and discharge modes based on the driving information and determines a charging upper and lower limit SOC based on the road slope or road type information a road section on which the vehicle is traveling and the vehicle speed information in the road section. A charge or discharge command is output based on the charging upper limit SOC and the charging lower limit SOC."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for controlling battery state of charge in hybrid electric vehicle","description":"A method and apparatus for controlling battery state of charge (SOC) in a hybrid electric vehicle are provided to enable the efficient use of energy, the maximization of energy recovery, and the impro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9834199","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.
