The invention provides an intelligent control method and device for quick charging of a battery, and the method comprises the steps: obtaining a real-time battery state parameter when a vehicle battery is charged; judging whether the real-time battery state parameters conform to a combined quick charging condition or not; when the real-time battery state parameters meet the combined quick charging condition, combined charging is carried out on the vehicle battery based on a constant-current stepped charging mode and a positive and negative pulse charging mode; and when the real-time battery state parameters do not meet the combined fast charging condition, the vehicle battery is charged based on a constant-current stepped charging mode. Therefore, the method and the device can improve the charging rate of the vehicle battery and realize the high-power fast charging effect of the power battery.

本申请提供一种电池快充智能控制方法及装置，该方法包括：在车辆电池充电时，获取实时电池状态参数；判断实时电池状态参数是否符合组合式快充条件；当实时电池状态参数符合组合式快充条件时，基于恒流阶梯充电方式和正负脉冲充电方式对车辆电池进行组合式充电；当实时电池状态参数不符合组合式快充条件时，基于恒流阶梯充电方式对车辆电池进行充电。可见，该方法及装置能够提高车辆电池的充电速率，实现动力电池大功率快充的效果。
