A charge current from a battery charging circuit is provided. If a charge voltage is above the lower voltage set-point and below the upper voltage set-point and the charge current exceeds the temperature-dependent upper current set-point, timer is started. If the timer reaches a time limit value while the charge current exceeds the temperature-dependent upper current set-point and the charge voltage is between the lower voltage set-point and the upper voltage set-point, the charge current is reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining a vehicle battery","description":"A method is provided for determining a lower voltage set-point, an upper voltage set-point, a temperature-dependent upper current set-point, a time limit value, and a lower current hysteresis threshol","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9789784","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.
