Electronic device, and battery abnormality monitoring method and monitoring system thereof

A battery abnormality monitoring system, applicable to an electronic device, comprising:

• a differential amplification circuit, configured to obtain a battery voltage of a battery of the electronic device in real time when the electronic device is in an on state;
• a current detection circuit, configured to obtain a consumption current of the battery in real time when the electronic device is in the on state;
• and
• a controller, configured to determine whether a voltage jump occurs in the battery based on the battery voltage obtained in real time, to further determine whether an abrupt change occurs in the consumption current of the battery when the voltage jump occurs in the battery, and to determine that an abnormality occurs currently in the battery when the voltage jump occurs in the battery and the abrupt change does not occur in the consumption current of the battery.

An electronic device, comprising a housing, a battery, a processor, a memory, and a circuit board, wherein:

• the circuit board is enclosed by the housing;
• the processor and the memory are positioned on the circuit board;
• the battery is configured to provide power for the electronic device;
• the memory is configured to store executable program codes;
• and
• the processor is configured to run a program corresponding to the executable program codes by reading the executable program codes stored in the memory, to perform following operations:
• 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 in an on state;
• 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.
