    摘要： A battery control device for a battery module includes a plurality of integrated circuits. Each integrated circuit includes: a constant voltage circuit that lowers a total voltage of a battery cell group corresponding to the integrated circuit to an integrated circuit internal voltage; a signal generation circuit that generates, based upon a first signal provided by a higher-order control circuit, a second signal assuming a wave height value different from a wave height value of the first signal and outputs the second signal; and a startup circuit that includes a first comparator assuming a first decision-making threshold value corresponding to the first signal and a second comparator assuming a second decision-making threshold value corresponding to the second signal, and starts up the constant voltage circuit in response to a change in an output from at least either the first comparator or the second comparator.

    摘要： A vehicle power supply device comprises a lithium battery module that includes a plurality of lithium battery cells, first control devices, voltage detection harnesses via which terminal voltages at individual lithium battery cells are input to the first control devices, a second control device and a signal transmission path through which signals are transmitted. The first control device comprises a selection circuit that selects terminal voltages at individual lithium battery cells, a voltage measurement circuit that measures the selected terminal voltages, balancing switches used to discharge individual lithium battery cells, a balancing switch control circuit that controls open/close of the balancing switches, and a diagnosis circuit for detecting an electrically abnormal connection in the detection harnesses.
