Abstract
A method for monitoring battery safety is provided and includes the following operations. Duration of a constant-voltage charging stage when a terminal device is charged is acquired. A battery of the terminal device is determined to be abnormal, when the duration is longer than or equal to a preset time period.
Claims18
A method for monitoring battery safety, comprising:
- acquiring duration of a constant-voltage charging stage when a battery of a terminal device is charged, wherein a charging process of the battery comprises at least one of a trickle charging stage, a constant-current charging stage, and the constant-voltage charging stage, the constant-voltage charging stage ends when the battery is fully charged;
- determining whether the duration is longer than or equal to a preset time period corresponding to a charging mode of the terminal device, wherein the charging mode is a first charging mode or a second charging mode, charging speed of the first charging mode is higher than that of the second charging mode, the first charging mode and the second charging mode each corresponds to one preset time period and the preset time period corresponding to the first charging mode is shorter than the preset time period corresponding to the second charging mode wherein the charging current is greater than 2.5 A in the first charging mode, and a rated output voltage is equal to 5 V and a rated output current is less than or equal to 2.5 A in the second charging mode;
- and
- determining the battery of the terminal device being abnormal, when the duration is longer than or equal to the preset time period.

A terminal device, comprising:
- a battery;
- at least one processor;
- and
- a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, causes the at least one processor to carry out actions, comprising:
- determining duration of a constant-voltage charging stage when the battery is charged, wherein a charging process of the battery comprises at least one of a trickle charging stage, a constant-current charging stage, and the constant-voltage charging stage, the constant-voltage charging stage ends when the battery is fully charged;
- determining whether the duration is longer than or equal to a preset time period corresponding to a charging mode of the terminal device, wherein the charging mode is a first charging mode or a second charging mode, charging speed of the first charging mode is higher than that of the second charging mode, the first charging mode and the second charging mode each corresponds to one preset time period and the preset time period corresponding to the first charging mode is shorter than the preset time period corresponding to the second charging mode, wherein the charging current is greater than 2.5 A in the first charging mode, and a rated output voltage is equal to 5 V and a rated output current is less than or equal to 2.5 A in the second charging mode;
- and
- determining the battery of the terminal device being abnormal, when the duration is longer than or equal to the preset time period.
