Problems solved by technology
[0018] But above-mentioned rechargeable battery 4 management method has following shortcoming, when rechargeable battery 4 capacity is saturated state, and when notebook computer 1 is connected external power supply by power conversion unit 6, notebook computer 1 can produce high heat after long time operation, and notebook computer 1 The high heat generated will be transferred to the rechargeable battery 4
Therefore, rechargeable battery 4 can be in high heat and saturated state for a long time, makes rechargeable battery 4 accelerate aging and shortens the service life of rechargeable battery 4

Embodiment Construction
[0036] In order to describe the technical content, purpose and effect of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0037] see figure 1 and image 3 Therefore, the rechargeable battery management method for electronic devices of the present invention can be applied to existing electronic products, such as notebook computers, personal data processors, and mobile phones. Taking the notebook computer 1 as an example, a method for managing a rechargeable battery of an electronic device according to the present invention includes the following steps:
[0038] S001: Turn on the notebook computer 1;
[0039] S002: The processing unit 8 judges whether the notebook computer 1 is connected to an external power supply through the power conversion unit 6. If the notebook computer 1 is connected to an external power supply, then execute S003, otherwise, repeatedly execute S002;
[0040] S003...

The invention provides a method for managing a rechargeable battery of an electronic device, which is used for sensing and controlling a rechargeable battery on the electronic device and comprises the steps of; firstly, obtaining allowance and temperature of the rechargeable battery by a processing unit in the electronic device; secondly, judging whether the allowance is more than an allowance preset value by the processing unit, judging whether the temperature is more than a temperature preset value by the processing unit; and thirdly, when the allowance of the rechargeable battery is more than the allowance preset value and the temperature of the rechargeable battery is more than the temperature preset value, sending a first signal by the processing unit for controlling the rechargeablebatter for discharging. Therefore, if the temperature of the rechargeable battery raises, the rechargeable battery is discharged to the preset allowance for avoiding rapid ageing of the rechargeable battery, and further the service life of the rechargeable battery is prolonged.
Description
technical field [0001] The invention relates to a rechargeable battery management method of an electronic device, in particular to a rechargeable battery management method capable of prolonging the service life of the rechargeable battery. Background technique [0002] At present, in order to meet the needs of portability and space-saving, the development trend of electronic products is to develop in the direction of light, thin and small. More common products such as notebook computers, personal data processors, mobile phones, etc., follow this development trend. Looking at the above-mentioned products, in order to make the application of the electronic products more mobile, the existing electronic products are all equipped with rechargeable batteries as working power sources. [0003] see figure 1 The notebook computer 1 is provided with a host 2, a rechargeable battery 4 and a power conversion unit 6, the rechargeable battery 4 is a lithium-ion battery, and the power con...
