摘要： PROBLEM TO BE SOLVED: To provide a reliable battery control device by monitoring interrupt processing.
SOLUTION: The battery control device includes a decision means. The decision means individually counts the numbers of times of generation of the following interrupt signals by a counting means: a first interrupt signal for causing interrupt processing through a first communication means (LIN); and a second interrupt signal for causing interrupt processing through a second communication means (CAN). Thereafter, the decision means calculates the sum of the number of times of generation of the first interrupt signal (907) and the number of times of generation of the second interrupt signal (904) counted by the counting means in a predetermined time (909). It compares the sum with a preset predetermined total number of times of interruption (910) and when they agree with each other, it determines that a second control device is normally operating (911).
