Problems solved by technology

[0003] Take the lithium battery commonly used in electronic equipment as an example. When the lithium battery itself is affected by temperature, the voltage fluctuation is very large, but the fuel gauge may not respond very timely, which leads to the following problems in recharging: (1) It is not easy Trigger battery recharging, which will cause the power in the battery to be exhausted and affect the user's use; (2) Continuously resend the battery recharging, thus affecting the service life of the battery

Embodiment Construction

[0075] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0076] When batteries, such as lithium batteries, are affected by temperature, the voltage fluctuates greatly. Therefore, if the same recharging threshold is used at high temperature and low temperature, it will be difficult to trigger battery recharging, which will cause the power in the battery to be exhausted and affect user use, or will continuously trigger battery recharging. Thus affecting ...

Abstract

The present disclosure relates to a battery charging method, device and medium. The method includes: acquiring the temperature and voltage of the battery; determining a recharge voltage of the battery based on the temperature; and determining whether to charge the battery based on the voltage and the recharge voltage. By adopting this method, the number of recharging times of the battery can be effectively reduced, the service life of the battery can be improved, and recharging can be normally triggered when the battery is at high temperature.

Description

technical field [0001] The present disclosure relates to the technical field of battery charging, in particular to a battery charging method, device and medium. Background technique [0002] At present, electronic devices have been used in various fields, and most of these electronic devices are powered by batteries. When the battery is connected to the power supply, when the power of the battery is lower than the recharging threshold value of the battery, recharging of the battery can be triggered. Usually, the recharging threshold of the battery is a fixed value, which is obtained by subtracting a voltage value from the rated voltage of the battery at normal temperature. [0003] Take the lithium battery commonly used in electronic equipment as an example. When the lithium battery itself is affected by temperature, the voltage fluctuation is very large, but the fuel gauge may not respond very timely, which leads to the following problems in recharging: (1) It is not easy ...
