The invention discloses a battery discharge power control method and device, a vehicle and electronic equipment, and the main technical scheme comprises the steps: querying the first discharge power of a target battery and a minimum monomer voltage drop threshold value based on the battery temperature, the residual electric quantity, the preset value of the first discharge power and the pre-corresponding relation of the minimum monomer voltage drop threshold value, if the minimum monomer voltage is smaller than or equal to the early warning voltage and the decreasing amplitude of the minimum monomer voltage at the preset time interval is larger than or equal to a minimum monomer voltage decreasing threshold value, it is confirmed that an early warning strategy is triggered, and the target battery is controlled to conduct discharging based on the first allowable discharging power; compared with the prior art, the corresponding early warning strategy is determined to be triggered according to the lowest single voltage of the power battery and the drop threshold of the lowest single voltage, and the power battery is controlled to discharge based on the first allowable discharge power obtained by reducing the first power drop coefficient, so that the change of the discharge power of the discharge tail end of the power battery is smoother; and the driving experience of the user is improved.

    本公开公开了电池放电功率的控制方法及装置、车辆及电子设备,主要技术方案包括:基于电池温度、剩余电量、第一放电功率的预设值与最低单体电压下降阈值的预先对应关系,查询目标电池的第一放电功率及最低单体电压下降阈值,若最低单体电压小于或等于预警电压,且最低单体电压在预设时间间隔的下降幅度大于或等于最低单体电压下降阈值,则确认触发预警策略,控制目标电池基于第一允许放电功率进行放电;与相关技术相比,根据动力电池最低单体电压及最低单体电压的下降阈值确定触发对应的预警策略,控制动力电池基于第一降功率系数缩小得到的第一允许放电功率进行放电,使动力电池放电末端放电功率的变化较为平滑,提升用户的驾驶体验。
