  "textContent": "A battery control device for a battery module includes a plurality of integrated circuits CC3A, ..., CC3N, CC4A, ..., CC4N. 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 20, 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.",
