The present disclosure provides an electronic device and a battery abnormality monitoring method and monitoring system. The battery abnormality monitoring method includes: obtaining a battery voltage of a battery of the electronic device in real time and obtaining a consumption current of the battery in real time, when the electronic device is on; determining whether a voltage jump occurs in the battery of the electronic device according to the battery voltage obtained in real time; further determining whether an abrupt change occurs in the consumption current of the battery when the voltage jump occurs in the battery; and determining that an abnormality occurs currently in the battery when the abrupt change does not occur in the consumption current of the battery.
