The invention discloses a range-extended electric vehicle, a range extender control method and device thereof and a storage medium, which are applied to the technical field of hybrid electric vehicle power supply, and the method comprises the following steps: when the vehicle speed of the range-extended electric vehicle is in a first vehicle speed interval, a range extender is controlled to operate at a first pre-selected working condition point, and the first pre-selected working condition point is matched with the first vehicle speed interval; if the vehicle speed of the extended-range electric vehicle is reduced from the first vehicle speed interval to a second vehicle speed interval, the range extender is controlled to be sequentially switched from the first pre-selected working condition point to a transition working condition point and a second pre-selected working condition point matched with the second vehicle speed interval for operation, the generated power of the range extender at the transition operating point is the same as that at the first pre-selected operating point, and the engine rotating speed at the transition operating point is smaller than that at the first pre-selected operating point. The technical problem that the NVH noise caused by the vehicle speed change to the range extender is large is at least solved.
本发明公开一种增程式电动汽车及其增程器控制方法、装置和存储介质,应用于混动车供电技术领域,该方法包括:针对增程式电动汽车的车速处于第一车速区间,控制增程器运行于第一预选工况点,第一预选工况点与第一车速区间适配;若增程式电动汽车的车速从第一车速区间下降至第二车速区间,控制增程器从第一预选工况点依次切换至过渡工况点以及与第二车速区间适配的第二预选工况点运行,增程器在过渡工况点的发电功率与在第一预选工况点的发电功率相同,且过渡工况点的发动机转速小于第一预选工况点的发动机转速。通过本发明至少降低车速变化给增程器带来的NVH噪声较大的技术问题。
