The invention relates to the technical field of automobile control, and discloses a pure electric vehicle driving power control method and device, equipment and a storage medium. The method comprises the steps of obtaining a position value corresponding to initial monomer voltage, and when the position value corresponding to the initial monomer voltage is lower than a preset position value, controlling the vehicle to enter a working state of a single power self-adaptive control mode, and in the working state, inquiring a first preset mapping relation table according to the position value corresponding to the current single voltage to determine a single power upper limit value; acquiring a current torque value and a current motor rotating speed, and determining current motor power according to the current torque value and the current motor rotating speed; and determining the current actual output power according to the monomer power upper limit value and the current motor power. By controlling the vehicle to enter the single power self-adaptive mode, self-adaptive control is carried out on the output power, the maximum output power is exerted to the maximum extent while the battery is protected, and therefore the output effectiveness of the pure electric vehicle is improved.
本发明涉及汽车控制技术领域，公开了一种纯电动车驱动功率控制方法、装置、设备及存储介质，所述方法包括：获取初始单体电压对应的位置值，在初始单体电压对应的位置值低于预设位置值时，控制车辆进入单体功率自适应控制模式的工作状态，在此工作状态下，根据当前单体电压对应的位置值查询第一预设映射关系表确定单体功率上限值；获取当前扭矩值和当前电机转速，根据当前扭矩值和当前电机转速确定当前电机功率；根据单体功率上限值和当前电机功率确定当前实际输出功率。通过控制车辆进入单体功率自适应模式，对输出功率进行自适应控制，在保护电池的同时，最大程度的发挥最大输出功率，从而提高纯电动车输出的有效性。
