The invention discloses an energy management method and device of a vehicle, the vehicle and a storage medium. The method comprises the steps that the charge state of the vehicle, the whole vehicle demand electric power and the total demand torque of a driving motor are obtained; determining a vehicle operation mode of the vehicle according to the state of charge and the required electric power of the whole vehicle; based on the vehicle operation mode, calculating the system electric efficiency corresponding to each preset distribution proportion of the vehicle according to the total demand torque of the driving motor; and selecting target electric efficiency from the system electric efficiency corresponding to each preset distribution proportion, and distributing the torque between the first driving motor and the second driving motor according to the preset distribution proportion corresponding to the target electric efficiency. The vehicle operation modes are divided according to the state of charge, and different torque distribution modes are adopted for different vehicle operation modes, so that the energy management of the vehicle is more detailed and accurate, and the performance of the whole vehicle is improved.

    本申请公开了一种车辆的能量管理方法、装置、车辆及存储介质,所述方法包括:获取车辆的荷电状态、整车需求电功率和驱动电机总需求扭矩;根据荷电状态和整车需求电功率确定车辆的车辆运行模式;基于车辆运行模式,根据驱动电机总需求扭矩计算车辆在各个预设分配比例对应的系统电效率;从各个预设分配比例对应的系统电效率中选择目标电效率,并根据目标电效率对应的预设分配比例对第一驱动电机和第二驱动电机之间的扭矩进行分配。本申请根据荷电状态对车辆运行模式划分,并针对不同车辆运行模式采用不同的扭矩分配方式,使得车辆的能量管理更加细致准确,有利于提高整车性能。
