Abstract

The invention discloses a battery charging control method, which comprises the following steps of: charging a battery under the control of a single chip microcomputer serving as a controller, disconnecting a charging circuit after the battery is charged for a preset period time, returning the battery voltage to the actual voltage, and detecting the voltage after the battery voltage is reduced to be stable, so that the detection interference caused by the charging voltage can be avoided; compared with an existing method for charging the battery through charging equipment, the method has the advantages that the charging effect is better, the phenomenon that the battery is overcharged is avoided, when the battery is fully charged, the voltage of the battery is closer to the full-charge voltage, namely the rated voltage, of the rechargeable battery, the performance of the battery is improved, and the service life of the battery is prolonged; in addition, according to the scheme, the single-chip microcomputer is selected as a controller to control charging, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of battery charging management, in particular to a battery charging control method. Background technique [0002] As an important energy supply equipment, batteries have the characteristics of stable voltage, stable current, and long-term stable power supply, and some batteries are simple in structure, easy to carry, easy to charge and discharge, not affected by external climate and temperature, and have stable and reliable performance. , play a great role in all aspects of modern social life. [0003] In the existing battery charging scheme, when the battery is charging, the charging voltage is continuously poured into the battery, and when the battery is fully charged, the battery will continue to maintain the voltage when the battery is not fully charged. It will cause great damage, shorten the service life of the battery, and greatly reduce the performance of the battery; moreover, most of the existing charging d...
