The invention relates to an enhanced starting method, a starting system and a vehicle. The extended-range starting method comprises the following steps: acquiring the residual electric quantity of a power battery of the vehicle; judging whether the residual electric quantity of the vehicle power battery is lower than a first threshold value; when the residual electric quantity of the vehicle power battery is lower than a first threshold value, starting a generator in a mode of limiting the power of a vehicle-mounted electric appliance, and dragging an engine by using the generator to realize the starting of the engine; after the engine is started, the engine drags the generator to generate electricity to charge a power battery of the vehicle. According to the range extending starting method and system and the vehicle, it can be guaranteed that the power battery of the vehicle supplies enough electricity to the generator by limiting the power of the vehicle-mounted electric appliance when the vehicle is low in electric quantity, starting of the generator under the low-electric-quantity condition is achieved, starting of an engine is achieved without the help of a starter, and the cost is reduced. The range-extending starting of the vehicle under the low electric quantity of the power battery is ensured, and meanwhile the cost of the vehicle is reduced.

    本发明涉及一种增强启动方法、启动系统以及车辆,增程启动方法包括:获取车辆动力电池的剩余电量;判断车辆动力电池的剩余电量是否低于第一阈值;当车辆动力电池的剩余电量低于第一阈值时,以限制车载电器功率的方式启动发电机,并利用发电机拖动发动机,实现发动机的启动;当所述发动机启动后,所述发动机拖动发电机发电,对车辆动力电池充电。本发明提供的一种增程启动方法、启动系统以及车辆可以在车辆低电量时,通过限制车载电器功率的方式,保证车辆的动力电池向发电机供足够的电,实现在低电量情况下发电机的启动,不需要借助启动机实现发动机的起动,既保证了动力电池低电量下车辆的增程起动,同时降低了车辆的成本。
