Abstract:
To provide a battery control device with which it is possible to acquire more accurate state information.SOLUTION: Provided is a battery control device comprising: a battery monitoring circuit for monitoring the state information of a battery cell; and a control unit for communicating with the battery monitoring circuit and transmitting an indication signal to the battery monitoring circuit that indicates that the state information be transmitted, thereby receiving the state information from the battery monitoring circuit. The battery monitoring circuit includes a first acquisition unit for repeatedly acquiring the state information at a first timing, a second acquisition unit for repeatedly acquiring the state information at a second timing which is different from the first timing, and a processing unit for transmitting the latest state information to the control unit, out of the state information acquired by the first acquisition unit and the state information acquired by the second acquisition unit, when the indication signal is received.SELECTED DRAWING: Figure 1
