摘要： In a flying capacitor type battery voltage detector on a circuit substrate, a large number of photo MOS switches having performance highly depending from temperature are dividedly disposed on front and back surfaces of the circuit substrate such that the photo MOS switches of the back surface are lying over the photo MOS switches of the front surface. Each of pairs of photo MOS switches connects a pair of surface lines with first and second floating lines to transmit an output voltage of each cell of a battery pack connected with the surface lines to a differential amplifier through a flying capacitor connected with the floating lines. Because of the division of the photo MOS switches on the surfaces of the circuit substrate, temperatures of the photo MOS switches have less dispersion, and an S/N ratio of each signal indicating the output voltage can be improved.

摘要： A first monitor circuit 50 and a second monitor circuit 60 each having an identical configuration are provided in a voltage monitor. A threshold switching section 41 switches a threshold of each of switching units 51 and 61 provided in the respective monitor circuits 50 and 60 to a same value. Each of comparators 53 and 63 compares the threshold with a reference voltage to output a result of the comparison. A fault detecting section 42 compares the respective outputs from the comparators 53 and 63 with each other to detect a characteristic shift of the threshold of each of the monitor circuits 50 and 60.

摘要： A plurality of voltage switching circuits 41 are provided in a switching unit 40 to relatively change a reference voltage to plural levels, thus detecting a spontaneous change of the reference voltage. A range of relative change in the reference voltage by the plurality of voltage switching circuits 41 is set to a usage voltage range 81 or 82 as a part of a total voltage range 80 of each of cells 1a to 1d. This eliminates the need to provide voltage switching circuits 41 required to relatively change the reference voltage over the total voltage range of each of the cells 1a to 1d, making it possible to minimize the number of the voltage switching circuits 41 for each of the cells 1a to 1d. Thus, it is possible to prevent the size of a battery pack control apparatus 2 from increasing.

摘要： In a battery pack manager that manages series-connected rechargeable unit cells, a cell equalizer equalizes the cell voltages by individually discharging the unit cells according to deviations from reference voltages. An overcharge/overdischarge detector detects an overcharge and an overdischarge state of each unit cell. An inhibit circuit prevents the cell equalizer from discharging the unit cells when the overcharge/overdischarge detector is activated to reduce the cell voltage variability, which would otherwise occur as a result of interference from the overcharge/overdischarge detector, so that the overcharge/overdischarge states of all unit cells can be determined with precision. Connecting lines of the unit cells are monitored to detect a line-cut. The inhibit circuit further inhibits the cell equalizer when the connecting lines are being monitored to reduce the cell voltage variability, which would otherwise occur as a result of interference from the line-cut detection, so that false line-cut detection is avoided.

摘要： The battery pack management apparatus for managing a battery pack having a series connection of battery cells is provided with a management unit for each of unit batteries each of which includes a single battery cell or a plurality of adjacent battery cells included in said battery pack. The battery pack management apparatus includes a selection circuit selecting one of the unit batteries, and a voltage detection circuit detecting a voltage across the selected unit battery. The management unit provided for the selected unit battery is configured to perform a management process (discharge process, for example) other than detection of the voltage across the selected unit battery on the selected unit battery.
