Management method of rechargeable battery of electronic device

Abstract

The invention provides a management method of a rechargeable battery of an electronic device, which is used for detecting and controlling the rechargeable battery on the electronic device. The management method comprises the following steps of: firstly, obtaining the temperature of the rechargeable battery by a processing unit arranged in the electronic device; secondly, judging whether the temperature is greater than a temperature default by the processing unit; finally, when the temperature of the rechargeable battery is greater than the temperature default, transmitting a first signal by the processing unit to reduce the charging voltage or the charging current of the rechargeable battery; and therefore, if the temperature of the rechargeable battery rises, a charging unit can be controlled to reduce the charging voltage and the charging current in order to avoid the accelerated aging of the rechargeable battery and prolong the service life of the rechargeable battery.

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...

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 The high heat generated by 1 will be transferred to the rechargeable battery 4. When the capacity of the rechargeable battery 4 is not saturated, and the notebook computer 1 is connected to an external power source through the power conversion unit 6, the charging unit 16 will charge the rechargeable battery 4 to the rechargeable battery 4. reach saturation

Therefore, the rechargeable battery 4 will continue to be in a state of high heat and saturation, which will accelerate the aging of the rechargeable battery 4 and shorten the service life of the rechargeable battery 4
