The invention discloses a range extender starting control method and device and a range-extended vehicle, and belongs to the technical field of range-extended vehicles. The control method for starting the range extender is applied to the range extending type vehicle. The control method comprises the steps that the current electric quantity and the self-discharging speed of a power battery are obtained; according to the current electric quantity, the self-discharging speed and a first electric quantity threshold value, determining a first duration for discharging the power battery to the first electric quantity threshold value; obtaining the self-discharge duration of the power battery; and if the self-discharge duration is greater than or equal to the first duration, controlling the range extender to start. The first duration is obtained through calculation, the range extender is awakened at a proper moment to charge the power battery, for the extended range vehicle stored in a long-term flameout state, the probability that the extended range vehicle cannot be started due to low electric quantity caused by continuous self-discharging of the power battery is reduced, the awakening time is accurate, frequent starting is avoided, energy management is optimized, and the energy consumption is reduced. And the starting performance of the extended-range vehicle is improved.

    本申请公开了一种增程器启动的控制方法、控制装置和增程式车辆,属于增程式车辆技术领域。所述增程器启动的控制方法应用于增程式车辆,所述控制方法包括:获取动力电池的当前电量和自放电速度;根据所述当前电量、所述自放电速度和第一电量阈值确定所述动力电池放电至所述第一电量阈值的第一时长;获取所述动力电池的自放电时长;若所述自放电时长大于或等于所述第一时长则控制所述增程器启动。通过计算获得第一时长,以在适当的时刻唤醒增程器给动力电池充电,对于长期熄火状态存放的增程式车辆,降低因为动力电池持续自放电导致电量低无法启动的几率,并且唤醒时机准确,避免频繁启动,优化了能源管理,提高了增程式车辆的启动性能。
