The battery pack is provided with an analog front-end 2 that detects battery 1 voltage, and a micro-controller 3 connected to the analog front-end 2 that accepts analog voltage signals from the analog front-end 2 as input. The micro-controller 3 switches voltage signals input from the analog front-end 2 to determine failure of the analog front-end 2 or the micro-controller 3.
