Electronic equipment and battery charging and discharging method thereof and device with storage function

Abstract

The invention discloses electronic equipment and a battery charging and discharging method thereof and a device with a storage function. The battery charging and discharging method comprises the stepsas follows: the electronic equipment obtains current remaining capacity and temperature of a battery and judges whether the remaining capacity is matched with a temperature range corresponding to thetemperature or not, wherein the remaining capacity is in inverse proportion to the temperature range; when the remaining capacity is greater than the capacity corresponding to the temperature range,the electronic equipment is provided with electricity through the battery; and the electronic equipment is provided with the electricity through an external power supply when the remaining capacity ofthe battery is matched with the capacity corresponding to the temperature range. Through the method, a corresponding relationship is built for the remaining capacity of the battery and the temperature range, and the remaining capacity of the battery is adjusted according to the temperature of the battery, so that good battery life can be ensured while the battery is prevented from bulging at hightemperature.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an electronic equipment, a method for charging and discharging a battery thereof, and a device with a storage function. Background technique [0002] With the continuous development of electronic devices (such as smart phones and routers, etc.), the functions of electronic devices are becoming more and more powerful, the user experience is becoming more and more rich, and the user environment and scenarios are becoming more and more complex. The normal use temperature range of the battery: 0~+45℃, the discharge temperature: -20~+60℃, but in fact, due to the long-term operation of the electronic device (such as chatting on WeChat, playing games, watching videos, etc.), there will be The temperature of the battery in the battery compartment of the terminal product is as high as 45-60°C or even higher, especially for terminals that are constantly charged with an external USB or a...

AI Technical Summary

Problems solved by technology

But there are many problems in this way: (1) because other heat dissipation materials are added, it is necessary to have enough large structural space, resulting in higher production costs

(2) It is necessary to develop and select a battery with special high-temperature performance, but the low-temperature performance cannot meet the end product, and it will increase the cost of materials

(3) Since the battery will stop discharging only when it is over-discharged, and the battery power is already very low when the battery reaches over-discharge, once the external power supply is disconnected, the battery life will not be guaranteed
