The invention discloses a peak power and continuous power switching control method for a power battery. Power switching is divided into a peak power reduction-to-continuous power control stage and a continuous power rise-to-peak power control stage. A control stage of rising from the continuous power to the peak power: rising from the continuous power to the peak power according to a set recovery rate for power output; in the stage, the peak power is gradually reduced to the continuous power, and the reduction rate is adjusted according to the power volume or the current volume. The method has the advantages that the problem that the experience of a vehicle owner is poor due to the fact that switching between the peak power and the continuous power is too fast is solved, and meanwhile battery abuse and influence on the service life of a battery are avoided. And smooth power switching is carried out by adopting a power-to-time integral vehicle, namely a power volume or current volume method. The peak power and the continuous power can be smoothly switched without sudden change, so that the experience of the whole vehicle is improved, and the battery is protected.

    本发明公开了一种动力电池峰值功率和持续功率切换控制方法,将功率切换划分为由峰值功率下降为持续功率控制阶段和由持续功率上升至峰值功率控制阶段;由持续功率上升至峰值功率控制阶段:按照设置的回升速率由持续功率上升至峰值功率进行功率输出;由峰值功率下降为持续功率控制阶段:在该阶段由峰值功率逐渐下降至持续功率,下降速率根据功率容积或电流容积进行调节。本发明的优点在于:解决这个峰值功率和持续功率的切换过快造成车主体验不好的问题,同时避免电池滥用,影响电池使用寿命。采用功率对时间的积分车,即功率容积或电流容积法进行平滑切换功率。峰值功率和持续功率能平滑切换,没有突变,既提升整车体验又保护电池。
