A battery-pack fault detecting device and a method for detecting a fault of a battery pack are provided. The battery-pack fault detecting device includes: N diodes, in which each battery is connected with one of the N diodes in anti-parallel via a detecting line; N+1 switches; a switch control circuit for switching on or switching off each switch; a voltage collecting circuit connected with the switch control circuit for collecting a voltage of the battery; an analog-to-digital conversion circuit for performing an analog-digital conversion on the voltage of the battery to obtain a digital voltage; a detection control circuit connected with the switch control circuit and the analog-to-digital conversion circuit, for controlling the switch control circuit to switch on or off each switch and for comparing the digital voltage with a preset value to judge a fault of the battery pack.

Provided are a broadcast switching device, method and terminal for switching between broadcast modes of a terminal, and the broadcast switching device includes: a second signal broadcasting unit; a first signal broadcasting unit; a signal reception module, connected respectively to the first signal broadcasting unit and the second signal broadcasting unit, configured to receive a first signal and a second signal and receive preferentially the first signal; a parsing module configured to parse the first signal to acquire signal strength of the first signal; a determination module configured to compare the signal strength of the first signal with a preset broadcasting strength and obtain a comparison result; and a switching module configured to control the signal reception module to receive the second signal when comparison result is that the signal strength of the first signal cannot meet the preset broadcasting strength. By means of technical solutions of the present disclosure, a digital broadcast signal can be switched to an FM broadcast signal when signal strength of the digital broadcast signal cannot meet broadcasting requirements, thus providing a user with optimal audio experiences.
