Embodiment Construction

[0010] figure 1 It is a structural diagram of an electronic device 100 with a battery 102 according to the present invention. To illustrate with the preferred embodiment, the electronic device 100 can be a notebook computer, and the battery 102 is a battery of the notebook computer, and the battery 102 can be used as a backup when the notebook computer has no external AC power supply power supply.

[0011] The electronic device 100 of the present invention also has: a battery temperature sensor 104 coupled to the battery 102 for sensing the temperature of the battery, and a control module 106 coupled to the battery temperature sensor 104, which can be a notebook type An embedded controller (Embedded Controller, EC) or a keyboard controller (Keyboard Controller, KBC) in the computer 100 itself or therein is used to execute a firmware of the present invention. The control module 106, for example, can set a first temperature of 64°C, a second temperature of 66°C higher than the...

Abstract

The invention relates to a method for protecting batteries of electronic equipment from overheating, comprising the following steps of sensing the temperature of a battery, performing a load-lowering operation when the battery temperature is up to a load-lowering temperature point, and removing the load-lowering operation when the battery temperature is lowered to a lowest critical temperature point, wherein the load-lowering temperature point is not lower than the lowest critical temperature point. The invention adjusts the battery temperature by using the load-lowering operation and removing load-lowering operation, thus avoiding damage of batteries due to overhigh temperature.

Description

technical field [0001] The present invention relates to a method for protecting a battery, and more particularly to a method for protecting a battery of an electronic device from overheating. Background technique [0002] In recent years, high-performance small batteries have been used in mobile devices such as notebook computers, mobile phones, and digital cameras. They have high energy density and can be repeatedly charged and discharged, which can meet the needs of general users for mobile devices. [0003] However, when the battery supplies power, it inevitably emits heat, and excessive heat accumulation often leads to damage to the battery, and even causes an explosion of an improperly designed battery, resulting in safety issues. Common electronic devices such as notebook computers and mobile phones all have mechanisms for protecting batteries. A common practice is to set a power-off temperature on the battery chip, and when the temperature of the battery rises to the...
