Abstract:
A control unit (16) of a replacement determination device charges one or more battery modules (10) as determination targets, and measures the voltage change value of the battery module (10) in a predetermined period of time from the time of stoppage of charge by using a voltage measuring device (14). If the voltage change value becomes equal to or more than a reference voltage change value consecutively a predetermined number of times which is equal to or more than one, the control unit determines that the battery module (10) needs to be replaced.
