The invention belongs to the technical field of hybrid electric vehicles, and particularly relates to a power request method of a hybrid electric vehicle, a readable storage medium and a vehicle, and the power request method comprises the following steps: determining a target SOC range of a power battery, dividing the target SOC range into at least two working intervals, and setting power correction parameters for each working interval; and when the SOC of the power battery is within the target SOC range, obtaining the request power sent to the fuel battery according to the power correction parameter of the working interval where the SOC is located. According to the method, the disturbance of the change of the required power of the whole vehicle to the SOC of the power battery can be well resisted, and the SOC of the power battery can be well maintained in the target SOC range, so that the high power performance and energy recovery performance are maintained, the NVH performance is improved, and overcharge is avoided.
本发明属于混合动力汽车技术领域,具体涉及一种混合动力汽车的功率请求方法、可读存储介质与车辆,本发明包括以下步骤:确定动力电池的目标SOC范围,将目标SOC范围划分出至少两个工作区间,并为各个工作区间设置功率修正参数;当动力电池的SOC在所述目标SOC范围内时,根据SOC所在的工作区间的功率修正参数获得向燃料电池发出的请求功率。本发明能够较好的抵抗整车需求功率的变化对动力电池的SOC的扰动,能够较好的维持动力电池的SOC在目标SOC范围内,从而保持较高动力性能与能量回收性能,提高NVH性能,并避免发生过充。
