Abstract

The embodiment of the invention provides a battery charging method and device, electronic equipment, an adapter and a charger. On one hand, the battery charging method comprises a first stage and a second stage; when an initial temperature of a battery is lower than a first rated temperature, the first stage is executed; after the first stage is completed, the second stage is executed; the first stage comprises a step of carrying out pulse charging and discharging on the battery to a specified stop condition; the second stage comprises at least one charging stage; each charging stage comprises at least one charging cycle; and each charging cycle comprises the steps of charging the battery for first charging time and carrying out pulse charging and discharging on the battery for second charging time. The battery charging method and device provided by the invention are used for solving the problems that the battery charging speed is relatively low and the charging efficiency is relatively low in a low temperature environment in the prior art.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of battery technology, in particular to a battery charging method and device, electronic equipment, an adapter and a charger. [0003] 【Background technique】 [0004] With the advancement of modern science and technology, electronic equipment has developed rapidly, and the related technologies of batteries, the core components of mobile electronic equipment in electronic equipment, have also made great progress. The main development directions include higher energy density and more Fast charging speed. [0005] At present, most of the batteries used in electronic equipment are lithium-ion batteries. Lithium-ion batteries have a problem of poor charging effect in low-temperature environments. For example, the power of the battery becomes worse, so the allowable charging current is significantly reduced, which limits its high-current fast charging in a low-temperature environment. Therefore, in the prior art, ...
