Abstract

A battery malfunction detection method includes: applying a preset number of vibration signals with different frequencies to a battery to be detected through a vibration generation device; collecting a response signal of the battery to be detected through a response collection device, where the response signal includes the preset number of vibration response amplitudes of the battery to be detected; determining whether the battery to be detected is malfunctioning according to the response signal.
