1. A battery management device for controlling supply of electric power from a battery device to a load of an electric device, the battery device including a plurality of battery units that are electrically connected, each of the battery units being independently controllable to switch between an output enabled state and an output disabled state, said battery management device comprising:
a device sensor configured to detect a present state of the electric device, and to output a detection signal corresponding to the present state of the electric device; a determining module that stores a predetermined threshold, that is coupled to said device sensor for receiving the detection signal, and that is configured to compare the detection signal with the predetermined threshold, and to output a device state signal according to a comparison result between the detection signal and the predetermined threshold, the device state signal indicating whether the electric device is in a normal state or an abnormal state; and a control module to be electrically connected to each of the battery units, electrically connected to said determining module for receiving the device state signal, and configured to switch each of the battery units to the output disabled state and thereby stop supply of the electric power to the load when the device state signal indicates that the electric device is in the abnormal state. |
