The invention belongs to the technical field of power batteries, and discloses a power control method and device of a power battery, equipment, a storage medium and a product. The real-time health degree corresponding to the power battery is determined according to the initial capacity and the target capacity corresponding to the power battery, and then the allowable power of the power battery in different health states is determined according to the real-time health degree and the EOL health degree of the power battery in the EOL state. And controlling the power of the power battery according to the actual output power of the vehicle in the running process and the allowable power of the power battery in different health states. According to the invention, the allowable power of the power battery in different health states can be determined according to the real-time health degree and the EOL health degree, and the influence of performance degradation caused by aging of the power battery is considered. And the power of the power battery is controlled according to the actual output power of the vehicle in the running process and the allowable power of the power battery in different health states, so that the power of the power battery can be effectively controlled.
本申请属于动力电池技术领域,公开了一种动力电池的功率控制方法、装置、设备、存储介质及产品。根据动力电池对应的初始容量和目标容量确定动力电池对应的实时健康度,然后根据实时健康度和动力电池在EOL状态下的EOL健康度确定动力电池在不同健康状态下的允许功率,再根据车辆在行驶过程中的实际输出功率和动力电池在不同健康状态下的允许功率对动力电池进行功率控制。本申请能够根据实时健康度和EOL健康度确定动力电池在不同健康状态下的允许功率,考虑到动力电池老化带来的性能衰减的影响,再根据车辆在行驶过程中的实际输出功率和动力电池在不同健康状态下的允许功率对动力电池进行功率控制,从而能够有效地对动力电池进行功率控制。
