摘要： PROBLEM TO BE SOLVED: To provide a battery pack controller that prevents an increase in scale of a circuit for changing a reference voltage in multiple stages. SOLUTION: A changing portion 40 is provided with multiple voltage switching circuits 41. A reference voltage is relatively changed in multiple stages to detect a spontaneous change in the reference voltage. The range of the reference voltage relatively changed by the voltage switching circuits 41 is set within voltage ranges 81, 82 of all the voltage ranges 80 of cells 1a to 1d. As a result, no voltage changing circuit 41 is required for changing the reference voltage relative to all the voltage ranges 80 of the voltages of the cells 1a to 1d. Consequently, the number of detected voltage changing circuits 41 required for the cells 1a to 1d is minimized, and an increase in the circuit scale of the battery pack controller 2 is suppressed.
