The invention discloses an intelligent charging system and charging method applied to a power battery. A 4-stage charging method is adopted, namely trickle charge; multi-stage constant current-constant voltage alternative charge; constant voltage charge and floating charge. A charging control system that automatically adjusts charging current and charging voltage, that is a control system of the invention, is used for distinguishing voltage and current thresholds, an equalizing charge condition, a charging terminal condition and the real-time acquired battery pack temperature, battery pack total voltage, single maximum and minimum voltage and the like of each charging stage according to a battery specification transmitted by a battery management system, and can automatically switch charging stages according to different conditions of practical batteries and different conditions of different batteries and so on, so that each charging stage in the charging process can be accurately controlled.
