The embodiment of the invention discloses a hybrid power system which comprises an energy storage device and a range extending power generation device, current output by the range extending power generation device is first direct current, current output by the energy storage device is second direct current, the first direct current and the second direct current are connected in parallel and converged on a direct current busbar, and the direct current busbar is connected with a driving system. The first direct current output by the range extending power generation device and the second direct current output by the energy storage device are connected in parallel and converged on the direct current busbar, so that double-source driving of the direct current busbar side to the vehicle is achieved, voltage generated by the range extending power generation device is always linked with the energy storage device, the dynamic balancing capacity is high, and the service life of the vehicle is prolonged. And in combination with the absorption capability of the wave crests and the wave troughs, a hybrid power output mode of the dynamically balanced energy balance body is directly realized on the direct current busbar side, so that the effects of improving efficiency and saving cost are achieved.

    本发明实施例公开了一种混合动力系统,包括储能装置和增程发电装置,该增程发电装置输出的电流为第一直流电,储能装置输出的电流为第二直流电,第一直流电与第二直流电并联连接,并汇流在直流母排上,该直流母排与驱动系统连接。通过增程发电装置输出的第一直流电和储能装置输出的第二直流电的并联连接,并汇流在直流母排上,实现直流母排侧对车辆的双源驱动,增程发电装置发出的电压始终和储能装置联动在一起,具有较强的动态均衡能力,结合波峰波谷的消纳能力,在直流母排侧直接实现动态均衡的能量平衡体的混合动力输出模式,达到提高效能,节约成本的效果。
