The invention relates to the technical field of vehicles, in particular to a vehicle power battery discharge power control method and device, a vehicle and a medium. Based on a preset interval meeting a preset discharge power use frequency condition, the current allowable discharge power of the power battery and the actual demand use power of the vehicle are compared, the estimated vehicle speed and the estimated driving power are combined to obtain the estimated allowable discharge power of the power battery, and the difference value between the estimated allowable discharge power and the estimated driving power is calculated; and when the difference value is greater than a preset threshold value, limiting the estimated allowable discharge power, and performing discharge power control on the power battery based on the limited allowable discharge power. According to the embodiment of the invention, the pre-estimated allowable discharge power of the power battery can be obtained, the pre-estimated allowable discharge power is limited, and the limited allowable discharge power is utilized to control the discharge power of the power battery, so that the mileage anxiety of a user is reduced, and the driving experience of the user is improved.

    本申请涉及车辆技术领域,特别涉及一种车辆的动力电池放电功率控制方法、装置、车辆及介质,方法包括:识别车辆的实际需求使用功率;基于预设的满足预设放电功率使用频率条件的区间,对比动力电池的当前许用放电功率和车辆的实际需求使用功率,结合预估车速、预估驱动功率获取动力电池的预估许用放电功率,并计算与预估驱动功率之间的差值,在差值大于预设阈值时,对预估许用放电功率进行限制,并基于限制后的许用放电功率对动力电池进行放电功率控制。本申请实施例可以获取动力电池的预估许用放电功率,并对预估许用放电功率进行限制,利用限制后的许用放电功率对动力电池进行放电功率控制,降低用户的里程焦虑,提升用户的驾乘体验。
