The invention discloses a multi-source integrated electric driving system of a commercial vehicle and a long-time-domain energy management method, and the system introduces a super capacitor as a short-time high-power output and rapid energy recovery device, and combines an intelligent energy management method. The method can comprehensively consider the dynamic power demand of a driving system, the power loss of the composite energy storage system, the life loss of an energy storage element and other factors, distributes the output power of a power battery and a super capacitor in the composite energy storage system, and gives full play to the respective advantages of the power battery and the super capacitor in the aspects of energy storage and supply. And the system not only can realize efficient scheduling of energy under different working conditions, but also can adjust the energy management method according to the performance attenuation of the energy storage element of the system in a long time domain, so that the comprehensive service life of the system is prolonged, and the long-term working stability of the system is ensured.

    本发明公开一种商用车多源集成式电驱动系统及长时域能量管理方法,该系统引入超级电容作为短时高功率输出与快速能量回收装置,并结合智能能量管理方法,能够综合考虑驱动系统动态功率需求、复合储能系统功率损耗以及储能元件寿命损耗等因素,对复合储能系统中动力电池与超级电容的输出功率进行分配,充分发挥动力电池与超级电容各自在能量储存和供给方面的优势,提高电驱动系统的性能与储能系统的寿命,且该系统不仅能够在不同工况下实现能量的高效调度,还能根据长时域内系统储能元件的性能衰减调整能量管理方法,延长系统综合寿命,保证系统长期工作的稳定性。
