The invention discloses an energy distribution method, device and equipment for a hybrid vehicle and a storage medium, and the method comprises the steps: obtaining a change curve between the power generation power of an engine and the oil consumption and power generation amount, and determining the vehicle demand oil consumption and power generation amount under the current working condition based on the change curve and the vehicle demand power under the current working condition. Discretizing a preset power generation power range, determining a plurality of to-be-selected power generation powers, and determining the oil consumption power generation amount corresponding to each to-be-selected power generation power; power generation time corresponding to each to-be-selected power generation power is determined, and candidate power generation power meeting a preset condition is determined from the to-be-selected power generation power; and based on the oil consumption generating capacity and the generating time corresponding to the candidate generating power and the current rotating speed difference value of the engine, target generating power of the engine under the current working condition is determined. According to the technical scheme, flexible distribution of energy of the hybrid vehicle is achieved, the energy utilization efficiency is improved, and energy waste is reduced.

本发明公开了一种混动车辆的能量分配方法、装置、设备及存储介质，该方法包括：获取发动机的发电功率与油耗发电量之间的变化曲线，并基于所述变化曲线和当前工况下的车辆需求功率，确定当前工况下的车辆需求油耗发电量。对预设发电功率范围进行离散化，确定多个待选发电功率，并确定每个待选发电功率对应的油耗发电量；确定每个待选发电功率对应的发电时间，并从待选发电功率中确定满足预设条件的候选发电功率；基于候选发电功率对应的油耗发电量和发电时间以及发动机的当前转速差值，确定当前工况下发动机的目标发电功率。通过本发明实施例的技术方案，以实现混动车辆能量的灵活分配，提高能量利用效率，减少能量的浪费。
