Abstract
A charging control method, a charging control device and a terminal are provided. According to the charging control method, it is determined whether the present charging stage is the constant voltage charging stage. The predetermined charging cut-off voltage is increased to the first charging cut-off voltage if the present charging stage is the constant voltage charging stage. The charging current and the battery voltage are periodically detected at a predetermined time interval. The first charging cut-off voltage is decreased by the predetermined voltage adjustment magnitude when the charging current is greater than or equal to the predetermined threshold and the battery voltage is greater than or equal to the safety voltage. The charging is completed when the charging current is less than the predetermined threshold.
