Abstract

The invention relates to an intelligent charger, comprising a charging state detection circuit for detecting the charging state of a rechargeable battery, a voltage conversion circuit and an optical coupling isolation circuit for providing a charging power supply, and a charging state detection circuit for charging according to the detection circuit. A single-chip microcomputer control circuit that controls the on-off state of the charging power supply. The invention changes the charging process, thereby realizing the maintenance of the battery and increasing the service life of the battery.

Description

technical field [0001] The invention relates to the charging field, in particular to an intelligent charger. Background technique [0002] Common rechargeable batteries include lithium batteries, nickel metal hydride batteries, polymer batteries, etc. The service life of a rechargeable battery and the time of a single cycle are not only closely related to the user's usage habits, but also closely related to the charger. A good charger can not only fully charge the battery in a short time, but also protect the battery from overvoltage and temperature by changing the charging process, so as to prolong the service life of the rechargeable battery. However, the existing chargers for charging rechargeable batteries have a single charging process and cannot maintain the battery, resulting in a relatively shortened service life of the rechargeable battery. In addition, conventional chargers continue to charge the battery after it is fully charged, which may shorten its lifespan. ...
