The invention belongs to the field of battery technology, and provides a battery protection method and a device thereof. The battery protection method comprises following steps: first time interval activation and obtaining of a first current value are carried out; if the first current value is capable of satisfying preset current protection trigger rules, current protection operation is carried out; second time interval activation and obtaining of a circuit voltage value and the temperature value of a protected circuit are carried out; if the voltage value and the temperature value are capableof satisfying preset electrical protection trigger rules, electrical protection operation is carried out; wherein the first time interval and the second time interval are set based on preset corresponding relation of priority with acquisition time. According to the battery protection method, battery protection device is activated at different time intervals, circuit, voltage, or temperature acquisition and detection operation of the battery protection device are carried out only after activation, the problems in conventional battery protection technology that long time continuous acquisitionof electrical parameters is needed, the power consumption is relatively large, battery duration is shortened, and electric quantity utilization efficiency is reduced are solved.
Description
Technical field [0001] The invention belongs to the technical field of batteries, and particularly relates to a battery protection method and a device thereof. Background technique [0002] With the continuous development and widespread popularity of mobile terminals, batteries, as power supply components of mobile terminals, are becoming more and more important. Therefore, how to take corresponding measures to protect the battery when the mobile terminal fails will also directly affect the stability of the mobile terminal. [0003] The existing battery protection technology generally monitors the electrical parameters of the circuit where the battery is located in real time, such as real-time monitoring of electrical parameters such as the current value, voltage value, and instantaneous power of the circuit. However, this method needs to continuously obtain the electrical parameters of the circuit for a long time and perform protection detection, and the power consumption is rela...
