The invention relates to a hydrogen internal combustion engine range extending power system, a control method and an automobile, and the system comprises a hydrogen internal combustion engine, a range extender generator, a motor controller, a power battery and a driving motor; the hydrogen internal combustion engine is in gas circuit connection with the hydrogen storage bottle, the hydrogen internal combustion engine is mechanically connected with the range extender generator, and the hydrogen internal combustion engine is used for driving the range extender generator to generate electricity and supplying power to the power battery and/or a driving motor in the hydrogen internal combustion engine range extending power system under the target operation working condition that any hydrogen internal combustion engine is in the operation state. The hydrogen internal combustion engine operates according to the excess air coefficient; the motor controller is electrically connected with the range extender generator, the driving motor and the power battery and used for controlling the power generation power of the range extender generator, the output power for transmitting power to the driving motor and the charging power for charging the power battery. By means of the supercharger, under the condition that the working load of the supercharger is reduced, the power performance equivalent to that of a gasoline engine can be achieved, and emission of nitric oxide is reduced.

    本发明涉及一种氢内燃机增程动力系统、控制方法及汽车,其中,系统包括:氢内燃机、增程器发电机、电机控制器、动力电池和驱动电机;氢内燃机与储氢瓶气路连接,氢内燃机与增程器发电机机械连接,在任意一种氢内燃机处于运行状态的目标运行工况下,氢内燃机用于驱动增程器发电机发电,并向动力电池和/或氢内燃机增程动力系统中的驱动电机进行供电,且氢内燃机按照过量空气系数运行;电机控制器分别与增程器发电机、驱动电机和动力电池电气连接,用于控制增程器发电机的发电功率、向驱动电机输电的输出功率以及对动力电池充电的充电功率。通过本申请,可以在降低增压器的工作负荷的情况下,能达到与汽油机相当的动力性能以及减少氮氧化物排放。
