The invention provides an energy distribution method and device, a storage medium and equipment, and the method comprises the steps: determining front and rear motor demand powers according to front and rear wheel end demand torques, a transmission ratio and a motor rotating speed, and subtracting the front and rear motor demand powers from the maximum power of a battery to obtain a spare power representing the remaining capacity of charging and discharging of the current battery, and determining the maximum available power of the front motor and the rear motor based on the demand power and the spare power of the front motor and the rear motor. Thus, the maximum power of the battery is dynamically distributed in real time through the required torque of the front wheel end and the rear wheel end, reasonable energy distribution is achieved, the vehicle can use the maximum available power obtained through calculation to limit the motor power, and therefore the phenomenon that the power battery is overcharged and overdischarged in the running process is effectively avoided.

    本申请提供一种能量分配方法、装置、存储介质及设备,该方法中,根据前、后轮端需求扭矩、传动比以及电机转速,确定前、后电机需求功率,再利用电池最大功率减去前、后电机需求功率,得到表征当前电池进行充放电的剩余能力的备余功率,进而基于前、后电机需求功率和备余功率,确定前、后电机的最大可用功率。如此,通过前、后轮端的需求扭矩,实时、动态地对电池最大功率进行分配,实现合理的能量分配,车辆可以使用计算得到的最大可用功率对电机功率进行限制,从而有效避免在行驶过程中动力电池出现过充过放现象。
