A battery controller controls the cell controller IC and a plurality of voltage detection lines measure the voltage across the terminals of the battery cell. The voltage detection lines connect positive and negative electrodes of the battery cell, respectively, to a plurality of voltage input terminals of the cell controller IC. A power line connects the positive electrode of the battery cell having the highest potential among the plurality of battery cells to a power supply terminal of the cell controller IC and a ground line which connects the negative electrode of the battery cell having the lowest potential among the plurality of battery cells to a ground terminal of the cell controller IC."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery system monitoring apparatus and electric storage device including the same for balancing a plurality of battery cells by discharging them based on voltage dependent turn-on resistance adapting of the balancing switch","description":"A battery system monitoring apparatus for monitoring a cell group having a plurality of battery cells, and includes a cell controller IC which monitors and controls the states of the plurality of batt","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9673640","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.
