摘要: This disclosure includes novel ways of implementing a power supply that powers a load. A main battery source produces a main battery voltage; each of multiple auxiliary battery sources in a set produces a respective auxiliary battery voltage. A controller initially sets a battery supply voltage to the main battery voltage, the main battery voltage is supplied to a power converter. The controller then monitors a magnitude of the battery supply voltage and adjusts the battery supply voltage supplied to the power converter based on a comparison of the magnitude of the battery supply voltage with respect to a threshold level. The adjusted battery supply voltage is provided from a serial connection of the main battery source and a first auxiliary battery source in the set.

摘要: A disconnection detection device includes CR filters, discharge circuits, and a detection unit. The CR filters are provided for respective battery cells of a battery pack in which the battery cells are connected in series. Each of the discharge circuits is connected between the battery cell and the CR filter and discharging the battery cell when cell voltages of the battery cells are made balanced. The detection unit successively discharges two of the battery cells connected in series, successively detects voltages of detection lines detecting contact voltages of the two battery cells after a predetermined time has passed from finish of discharge of each of the battery cells, and detects disconnection of each of the detection lines on the basis of a difference between the two detected voltages.
