Therefore, an ON control of a switch element takes long time to detect a disconnection state reliably. A battery monitoring system includes: a monitoring circuit corresponding to an assembled battery having a plurality of battery cells and which monitors states of the battery cells; voltage detection lines which are provided corresponding to the battery cells and which connect the battery cells with the monitoring circuit; and switch elements which are provided between the voltage detection lines and which adjust voltages of the battery cells, the battery monitoring system compares battery voltages of the adjacent battery cells with a varying threshold determined based on a voltage just before checking a disconnection state and detects disconnection states of the voltage detection lines according to the comparison result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery monitoring system","description":"When a battery voltage of a battery cell is high, it takes time for a detected voltage to drop to a fixed threshold.
